&lt;div&gt;According to available data a QXGA display version was never available, not even for CTO.&lt;br /&gt;
&lt;br /&gt;
Just because the HMM lists something, does not mean it was ever used in any shipping model.&lt;br /&gt;
&lt;br /&gt;
--[[User:Tonko|Tonko]] 04:13, 28 February 2006 (CET)&lt;br /&gt;
&lt;br /&gt;
AFAIK the QXGA display was only corporate option, not for public buyers. But good news are, that you can do the upgrade yourself, the QXGA LCD itself is needed, new inverter and LCD cable, also new LCD hinges are recommended, but that's not necessary, price of parts needed for this upgrade is nowadays about $500. This is not my personal experience, but several people here: [http://forum.thinkpads.com forum.thinkpads.com] did it succesfully. The R50p is IMHO the only one thinkpad that could go QXGA.&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;== Solution for T43, T6x ==&lt;br /&gt;
I hope I'm not breaking rules of this page. I've researched quite a lot on this topic and tried to solve it by editing BIOS. There are quite a lot obstacles, but in the end, I think I've succeeded. Though I'm not exactly that sure to risk a perfectly working machine, so I'd like to ask if anyone has a T43/T6x (perhaps with some motherboard issues, which allow it to power up, but it's unusable for work) which could be flashed with the modified BIOS to see if it still boots up. Thanks for any reply to ender@pikachu.cz (or here).&lt;br /&gt;
&lt;br /&gt;
== Affected Models ==&lt;br /&gt;
I am unsure about which models this applies to.  I have seen reports of this problem affecting a T41p, T43, X40, R31, X31, and T30; but I do not know how far back this problem goes or if there are exceptions.  If anyone has better information, please clarify/specify the &amp;quot;Affected Models&amp;quot; section. --[[User:Kevinoid|Kevinoid]] 05:44, 14 Dec 2005 (CET)&lt;br /&gt;
&lt;br /&gt;
I have a R40 model 2681-K9G that came without any mini-pci card so I bought a Intel PRO/Wireless 2915ABG mini-pci card for it. When I discovered that it would not work in my Thinkpad I came to this site to see if there was a fix. Seemed like there was, so I bought a mini-pci-to-PCI adapter and installed the card(s) in my desktop. Now I need to know what vendor and device ID strings to use when I flash the card's BIOS. Anyone have a list?&lt;br /&gt;
&lt;br /&gt;
== Solution on T43? ==&lt;br /&gt;
There were several edits to the previous page to the effect that &amp;quot;this didn't work for my T43&amp;quot;.  Although I do not weight this as highly credible (please just ask for help on the ML rather than adding random comments to pages), I did feel that it deserved a mention that the solution may not work on the T43.  If anyone can confirm or deny this statement, please do so (and possibly ask on the ML for solutions if it does not work for you). --[[User:Kevinoid|Kevinoid]] 05:44, 14 Dec 2005 (CET)&lt;br /&gt;
&lt;br /&gt;
== Confirmation - patch not working on T43 ==&lt;br /&gt;
I can confirm, that a &amp;quot;nvram/cmos&amp;quot; patch is not working on my T43, exact type 1871-A62. I tried several cards (some working without patch in another thinkpads (t40, t42, x40), but no success.--[[User:Jap|Jap]] 09:50, 13 June 2006 (CEST)&lt;br /&gt;
&lt;br /&gt;
== Hotplugging PCI device ==&lt;br /&gt;
I'd like to send out a '''BIG FAT WARNING''' that 'hotplugging' the mini-PCI card can easily lead to frying the system board, mini-PCI bus, or both. Yes, it happened to me... :-( Interrupting the boot process at the lilo boot menu, and then inserting the ipw2915abg card worked as a charm to circumvent the BIOS white list. However, somewhere it must have gone wrong because now the laptop hangs immediately when the IBM/Intel boot logos appear. --[[User:LJSBrokken|LJSBrokken]] 13:01, 20 July 2006 (GMT+1)&lt;br /&gt;
&lt;br /&gt;
== Z60 series ==&lt;br /&gt;
I tried this on a Lenovo Z60t. Bought an Intel Wireless card since the linux drivers for the madwifi are crap. I applied the C-Patch from here. Then after booting with the intel device installed I get some weird broadcom PXE boot messages displayed ontop of the key symbol for startup security. Even if I don't put my finger on the sensor, it continues with GRUB. At this point I can't use the keyboard, the key symbol is still displayed in the upper left corner. After a few secons grub starts with its default entry (Gentoo Linux). It all works, but no Wireless Adapter shows up in lspci.&lt;br /&gt;
&lt;br /&gt;
So, I don't have that 1802 error, but still can't use my wifi card. Any ideas?&lt;br /&gt;
&lt;br /&gt;
== G40 series ==&lt;br /&gt;
According to [[http://www.wifi-forum.com/wf/showthread.php?t=60620|this forum post]], the CMOS hack (I assume they are referring to the bit-twiddling code) works.  Does anyone else have anything to confirm this?  I might well try it myself (in which case I'll update the main table), but I'll have to at least get an aerial first.&lt;br /&gt;
&lt;br /&gt;
[[User:lentinj|lentinj]]&lt;br /&gt;
&lt;br /&gt;
== no dice on T43 ==&lt;br /&gt;
&lt;br /&gt;
Also can confirm the T43 is much more resistant to the unauthorized mini pci card problem. No 1802 didn't work (it worked for my T40). Changing the PCI class id to 0x0280 (networking device - other) also didn't shake the message. Finally, I tried to masquerade the card as a one of the whitelisted ones via the ath_info utility from madwifi. I made a mistake at this point and didn't update the subsystem vendor id / subsystem device id, just the primary pci vendor and device ids. I *still* got the warning message, and now the ath driver doesn't pick up the card, so I can't use ath_info. The card is basically bricked, unless I find time (ha ha) for some kernel hacking. Moral of the story is be careful with ath_info.&lt;br /&gt;
&lt;br /&gt;
== IBM R40e ==&lt;br /&gt;
&lt;br /&gt;
Have an IBM R40 &amp;amp; R40e, R40 - linux no-1802 cd worked flawlessly, r40e - linux no-1802 cd - hangs on confirmation the patching - maybe a keyboard error, but I dont have dock nor USB keyboard to try, the DOS CD, worked perfectly on the r40e (although I was a little nervous about bricking the R40e ;-). A little note - the r40e obviously dont have an antena - i'll have to get some, but its working even without antena for short range indoor (the accesspoint is about 3 meters away)&lt;br /&gt;
&lt;br /&gt;
== Other issues with unauthorized cards ==&lt;br /&gt;
&lt;br /&gt;
I'm not sure if this is common but my Intel Pro 2915ABG (not from IBM) works on my T41 (both from eBay so some patch was probably already applied) except that the WLAN LED on the laptop stays off all the time. If this is common to all non-authorized cards, this wiki article should mention this.&lt;br /&gt;
&lt;br /&gt;
It does the same for my r40 and not IBM intel 2200, I think that the led would work only if the PCI ID of the minipci card would be changed to IBM, but i dont know excatly how to do this, I just remember seeing it somewhere (kajencik - 24.1.2008)&lt;/div&gt;</summary>

&lt;hr /&gt;
&lt;div&gt;==Problem Description==&lt;br /&gt;
Although the MiniPCI slot is an industry standard and can accept any MiniPCI adapter, the IBM BIOS is set to only allow you to boot with an 'authorized' adapter installed. Attempts to install an unsupported card will result in the following message:&lt;br /&gt;
&lt;br /&gt;
   1802: Unauthorized network card is plugged in - Power off and remove the miniPCI network card.&lt;br /&gt;
&lt;br /&gt;
This is because the card's sub-vendor PCI-ID (which can be seen using ''lspci -v'') are checked against a [[Wikipedia:Whitelist|whitelist]] in the BIOS.  IBM's reasoning for this is that the combination of MiniPCI card and the integrated antenna in the ThinkPad needs to be certified by the US FCC (Federal Communications Commission).{{footnote|1}} or similar agencies in other countries.&lt;br /&gt;
&lt;br /&gt;
==Affected Models==&lt;br /&gt;
All machines with integrated WiFi, or machines with WiFi added&lt;br /&gt;
&lt;br /&gt;
==Affected Operating Systems==&lt;br /&gt;
All - problem is in the BIOS&lt;br /&gt;
&lt;br /&gt;
==Status==&lt;br /&gt;
* Workarounds exist for most affected models.&lt;br /&gt;
&lt;br /&gt;
==Solutions==&lt;br /&gt;
It may be possible to use the computer with the unauthorized card deactivated (but not removed).  Press {{key|F1}} to enter the BIOS and deactivate the WLAN card, then attempt to boot with the card disabled.  This does not make the wireless card work, but it may allow you to boot the computer normally.&lt;br /&gt;
&lt;br /&gt;
{{NOTE|Any of the following solutions should suffice to make the wireless card useable.  You only need to perform one of them.}}&lt;br /&gt;
&lt;br /&gt;
* You may can modify the BIOS whitelist to include the PCI-ID of the card you wish to use.  The complete instructions for this procedure are [http://www.paul.sladen.org/thinkpad-r31/wifi-card-pci-ids.html here].&lt;br /&gt;
{{WARN|It is dangerous to mess with your BIOS, you can easily make your machine unbootable, proceed with caution!}}&lt;br /&gt;
&lt;br /&gt;
* A safer and better method than modifying the BIOS is modifying the PCI-ID of the wlan card to match the authorized one(why? 1.you'll risk the wireless card instead of the motherbord 2.future BIOS updates will not create any problem 3.no problem with newer laptops with different BIOS, the only reqirement is to find an ID that is already listed in the BIOS that can be easily acheived if community maintain a compatibility table). The instructions are [http://www.dagarlas.org/stuff/computing/article0001.php here].  This page is for Atheros-based cards and HP notebooks, but it applies to Thinkpads as well. It also has links on how to edit the PCI-ID on Intel Pro Wireless cards.  &lt;br /&gt;
Instruction for intel 2200/2915 cards are [http://stachon.webpark.cz/ipw-eeprom.html here]. &lt;br /&gt;
{{NOTE|Modifying your PCI-ID will require either a laptop without a BIOS lock or a PCI adapter for your desktop.  Also, this procedure can render your card useless, but that's better than bricking your laptop.}}&lt;br /&gt;
&lt;br /&gt;
* You can use the [[Problem with error 01C9 - More than one Ethernet devices | no-1802 and no-01C9 Linux Live CD]] without applying the no-01C9 patch. It is very convenient to use and based on the C code below.&lt;br /&gt;
&lt;br /&gt;
* You can use the DOS [http://jcnp.pku.edu.cn/~shadow/1802/no-1802.com no-1802] utility, written by Tisheng Chen.{{footnote|2}} It will set a certain bit in the CMOS memory which disables the whitelist check, but it has been reported not to work on the latest machines, such as the T43 and X41&lt;br /&gt;
&lt;br /&gt;
* You can compile and run (as root) the following C-code, which was written by Matthew Garrett. It was based on the code written by Vojtech Pavlik, which in turn was based on the assembly used in the no-1802 program. {{footnote|3}}&lt;br /&gt;

		<summary type="html">&lt;p&gt;Kajencik: New section: IBM R40e&lt;/p&gt;
&lt;hr /&gt;
&lt;div&gt;== Affected Models ==&lt;br /&gt;
I am unsure about which models this applies to.  I have seen reports of this problem affecting a T41p, T43, X40, R31, X31, and T30; but I do not know how far back this problem goes or if there are exceptions.  If anyone has better information, please clarify/specify the &amp;quot;Affected Models&amp;quot; section. --[[User:Kevinoid|Kevinoid]] 05:44, 14 Dec 2005 (CET)&lt;br /&gt;
&lt;br /&gt;
I have a R40 model 2681-K9G that came without any mini-pci card so I bought a Intel PRO/Wireless 2915ABG mini-pci card for it. When I discovered that it would not work in my Thinkpad I came to this site to see if there was a fix. Seemed like there was, so I bought a mini-pci-to-PCI adapter and installed the card(s) in my desktop. Now I need to know what vendor and device ID strings to use when I flash the card's BIOS. Anyone have a list?&lt;br /&gt;
&lt;br /&gt;
== Solution on T43? ==&lt;br /&gt;
There were several edits to the previous page to the effect that &amp;quot;this didn't work for my T43&amp;quot;.  Although I do not weight this as highly credible (please just ask for help on the ML rather than adding random comments to pages), I did feel that it deserved a mention that the solution may not work on the T43.  If anyone can confirm or deny this statement, please do so (and possibly ask on the ML for solutions if it does not work for you). --[[User:Kevinoid|Kevinoid]] 05:44, 14 Dec 2005 (CET)&lt;br /&gt;
&lt;br /&gt;
== Confirmation - patch not working on T43 ==&lt;br /&gt;
I can confirm, that a &amp;quot;nvram/cmos&amp;quot; patch is not working on my T43, exact type 1871-A62. I tried several cards (some working without patch in another thinkpads (t40, t42, x40), but no success.--[[User:Jap|Jap]] 09:50, 13 June 2006 (CEST)&lt;br /&gt;
&lt;br /&gt;
== Hotplugging PCI device ==&lt;br /&gt;
I'd like to send out a '''BIG FAT WARNING''' that 'hotplugging' the mini-PCI card can easily lead to frying the system board, mini-PCI bus, or both. Yes, it happened to me... :-( Interrupting the boot process at the lilo boot menu, and then inserting the ipw2915abg card worked as a charm to circumvent the BIOS white list. However, somewhere it must have gone wrong because now the laptop hangs immediately when the IBM/Intel boot logos appear. --[[User:LJSBrokken|LJSBrokken]] 13:01, 20 July 2006 (GMT+1)&lt;br /&gt;
&lt;br /&gt;
== Z60 series ==&lt;br /&gt;
I tried this on a Lenovo Z60t. Bought an Intel Wireless card since the linux drivers for the madwifi are crap. I applied the C-Patch from here. Then after booting with the intel device installed I get some weird broadcom PXE boot messages displayed ontop of the key symbol for startup security. Even if I don't put my finger on the sensor, it continues with GRUB. At this point I can't use the keyboard, the key symbol is still displayed in the upper left corner. After a few secons grub starts with its default entry (Gentoo Linux). It all works, but no Wireless Adapter shows up in lspci.&lt;br /&gt;
&lt;br /&gt;
So, I don't have that 1802 error, but still can't use my wifi card. Any ideas?&lt;br /&gt;
&lt;br /&gt;
== G40 series ==&lt;br /&gt;
According to [[http://www.wifi-forum.com/wf/showthread.php?t=60620|this forum post]], the CMOS hack (I assume they are referring to the bit-twiddling code) works.  Does anyone else have anything to confirm this?  I might well try it myself (in which case I'll update the main table), but I'll have to at least get an aerial first.&lt;br /&gt;
&lt;br /&gt;
[[User:lentinj|lentinj]]&lt;br /&gt;
&lt;br /&gt;
== no dice on T43 ==&lt;br /&gt;
&lt;br /&gt;
Also can confirm the T43 is much more resistant to the unauthorized mini pci card problem. No 1802 didn't work (it worked for my T40). Changing the PCI class id to 0x0280 (networking device - other) also didn't shake the message. Finally, I tried to masquerade the card as a one of the whitelisted ones via the ath_info utility from madwifi. I made a mistake at this point and didn't update the subsystem vendor id / subsystem device id, just the primary pci vendor and device ids. I *still* got the warning message, and now the ath driver doesn't pick up the card, so I can't use ath_info. The card is basically bricked, unless I find time (ha ha) for some kernel hacking. Moral of the story is be careful with ath_info.&lt;br /&gt;
&lt;br /&gt;
== IBM R40e ==&lt;br /&gt;
&lt;br /&gt;
Have an IBM R40 &amp;amp; R40e, R40 - linux no-1802 cd worked flawlessly, r40e - linux no-1802 cd - hangs on confirmation the patching - maybe a keyboard error, but I dont have dock nor USB keyboard to try, the DOS CD, worked perfectly on the r40e (although I was a little nervous about bricking the R40e ;-). A little note - the r40e obviously dont have an antena - i'll have to get some, but its working even without antena for short range indoor (the accesspoint is about 3 meters away)&lt;/div&gt;</summary>

&lt;hr /&gt;
&lt;div&gt;==Problem Description==&lt;br /&gt;
Although the MiniPCI slot is an industry standard and can accept any MiniPCI adapter, the IBM BIOS is set to only allow you to boot with an 'authorized' adapter installed. Attempts to install an unsupported card will result in the following message:&lt;br /&gt;
&lt;br /&gt;
   1802: Unauthorized network card is plugged in - Power off and remove the miniPCI network card.&lt;br /&gt;
&lt;br /&gt;
This is because the card's sub-vendor PCI-ID (which can be seen using ''lspci -v'') are checked against a [[Wikipedia:Whitelist|whitelist]] in the BIOS.  IBM's reasoning for this is that the combination of MiniPCI card and the integrated antenna in the ThinkPad needs to be certified by the US FCC (Federal Communications Commission).{{footnote|1}} or similar agencies in other countries.&lt;br /&gt;
&lt;br /&gt;
==Affected Models==&lt;br /&gt;
All machines with integrated WiFi, or machines with WiFi added&lt;br /&gt;
&lt;br /&gt;
==Affected Operating Systems==&lt;br /&gt;
All - problem is in the BIOS&lt;br /&gt;

* Workarounds exist for most affected models.&lt;br /&gt;
&lt;br /&gt;
==Solutions==&lt;br /&gt;
It may be possible to use the computer with the unauthorized card deactivated (but not removed).  Press {{key|F1}} to enter the BIOS and deactivate the WLAN card, then attempt to boot with the card disabled.  This does not make the wireless card work, but it may allow you to boot the computer normally.&lt;br /&gt;
&lt;br /&gt;
{{NOTE|Any of the following solutions should suffice to make the wireless card useable.  You only need to perform one of them.}}&lt;br /&gt;
&lt;br /&gt;
* You may can modify the BIOS whitelist to include the PCI-ID of the card you wish to use.  The complete instructions for this procedure are [http://www.paul.sladen.org/thinkpad-r31/wifi-card-pci-ids.html here].&lt;br /&gt;
{{WARN|It is dangerous to mess with your BIOS, you can easily make your machine unbootable, proceed with caution!}}&lt;br /&gt;
&lt;br /&gt;
* A safer and better method than modifying the BIOS is modifying the PCI-ID of the wlan card to match the authorized one(why? 1.you'll risk the wireless card instead of the motherbord 2.future BIOS updates will not create any problem 3.no problem with newer laptops with different BIOS, the only reqirement is to find an ID that is already listed in the BIOS that can be easily acheived if community maintain a compatibility table). The instructions are [http://www.dagarlas.org/stuff/computing/article0001.php here].  This page is for Atheros-based cards and HP notebooks, but it applies to Thinkpads as well. It also has links on how to edit the PCI-ID on Intel Pro Wireless cards.  &lt;br /&gt;
Instruction for intel 2200/2915 cards are [http://stachon.webpark.cz/ipw-eeprom.html here]. &lt;br /&gt;
{{NOTE|Modifying your PCI-ID will require either a laptop without a BIOS lock or a PCI adapter for your desktop.  Also, this procedure can render your card useless, but that's better than bricking your laptop.}}&lt;br /&gt;
&lt;br /&gt;
* You can use the [[Problem with error 01C9 - More than one Ethernet devices | no-1802 and no-01C9 Linux Live CD]] without applying the no-01C9 patch. It is very convenient to use and based on the C code below.&lt;br /&gt;
&lt;br /&gt;
* You can use the DOS [http://jcnp.pku.edu.cn/~shadow/1802/no-1802.com no-1802] utility, written by Tisheng Chen.{{footnote|2}} It will set a certain bit in the CMOS memory which disables the whitelist check, but it has been reported not to work on the latest machines, such as the T43 and X41&lt;br /&gt;
&lt;br /&gt;
* You can compile and run (as root) the following C-code, which was written by Matthew Garrett. It was based on the code written by Vojtech Pavlik, which in turn was based on the assembly used in the no-1802 program. {{footnote|3}}&lt;br /&gt;

*avoid exposing the battery (or notebook) to excessive heat&lt;br /&gt;
|&lt;br /&gt;
*avoid deep discharges except when resetting fuel gauge or reconditioning a battery;  partial dis-/recharges are better for the battery lifetime (note: fuel gauge will slowly get inaccurate over time)&lt;br /&gt;
*remove battery when on AC (due to heat)&lt;br /&gt;

*avoid charging if battery is nearly full, unless you will need its full capacity soon; keep it on the 30%-85% charged range&lt;br /&gt;
*keep notebook off while charging due to heat&lt;br /&gt;
*fully discharge, then fully charge battery when needed to recalibrate fuel gauge;  newer battery pack models require this less often, old ones might need it as often as every 30 cycles&lt;br /&gt;

&lt;br /&gt;
===Battery health===&lt;br /&gt;
Batteries, especially of the modern Li-Ion type, wear out quicker when they hold a large charge or are subject to higher temperatures (see above).&lt;br /&gt;
&lt;br /&gt;
If you use your laptop at a desk, reduce battery wear by maintaining an appropriate charge level.  When  possible, remove Li-ion batteries while operating from AC as the notebook gets hot enough inside for that to damage the battery in the long run, even if charging is stopped.&lt;br /&gt;
&lt;br /&gt;
On recent ThinkPads, charging thresholds can be configured in the bundled software.  Under Linux, this is supported on recent models by the [[tp_smapi]] driver (and even without &amp;lt;tt&amp;gt;tp_smapi&amp;lt;/tt&amp;gt;, if you have a dual-boot setup, you can set the thresholds under Windows and they will be remembered as long as you don't power off your machine with AC disconnected; suspend to RAM is OK). Have a look at [[How to use UltraBay batteries]].&lt;br /&gt;
&lt;br /&gt;
If you have spare Li-ion battery packs, store them at 40% charge in a cool place (15C being a recommended temperature, do not let the batteries freeze).  If storing inside a refrigerator, beware of humidity, and be careful with cold spots that can easily freeze the battery if anything goes wrong.&lt;br /&gt;
&lt;br /&gt;
===The problem with 600 series batteries===&lt;br /&gt;
ThinkPad 600 power management causes batteries to die before they should. Read more about this on the [[Problem with ThinkPad 600 batteries|associated problem page]].&lt;br /&gt;
&lt;br /&gt;
===Reviving batteries===&lt;br /&gt;
Some people experience sudden drops in their batteries capacity.  A way to get these batteries back to full capacity is to run the &amp;quot;Battery Rundown&amp;quot; function of IBMs &amp;quot;PC Doctor for DOS&amp;quot;.  The program is downloadable from IBMs support site as three floppy disk images.  Make sure you get the specific version of program made for your ThinkPad model.

&lt;br /&gt;
I have recently made an interesting discovery, I have an R40 with two main batteries, both of them have aproximately about under 200 cycles and are nowadays 4 years old, projected capacity for R40/R32 main battery is 57Wh, and both my batteries were about 30Wh, than I left my notebook with one of them about a day in a standby mode, as long as it powered off itself because of low battery power, when I turned it on I saw the battery capacity at about 42Wh, than, I did this too for the second battery and I got even about 46Wh, I think I could go even higher with letting the battery discharge completely from 100% in standby, I think this has something to do with low power consumption in standby mode, it may work for you too.&lt;br /&gt;

==Cleaning the Interior==&lt;br /&gt;
{{WARN|The following instructions are not appropriate for all ThinkPad models. Please consult the hardware maintenance guide or on-line disassembly instructions for your model.}}&lt;br /&gt;
Most ThinkPad models (particularly the A-series and the T-series) tend to accumulate a lot of interior dust which they draw from their ventilation fan.  A good dusting every few months is advised. The procedure is as follows.&lt;br /&gt;
&lt;br /&gt;

===Other models (which?)===&lt;br /&gt;
#Unplug the computer.&lt;br /&gt;
#Remove the battery.&lt;br /&gt;
#Turn the ThinkPad over and find two to three screws with upraised double-arrows pointing to them.&lt;br /&gt;
#Unscrew these screws and set them aside.&lt;br /&gt;
#Press the silver area underneath where the battery used to be.  The front of the keyboard will pop up.&lt;br /&gt;
#Turn the ThinkPad right side up and gently remove the keyboard, pulling it toward you.&lt;br /&gt;
#There is one connector between the ThinkPad and the keyboard.  Disconnect it, and set the keyboard aside.&lt;br /&gt;
#If there is a small black plastic separator under the keyboard, remove it and set it aside.&lt;br /&gt;
#The fan should be visible in the upper left.  That entire area will likely be dusty.  With a can of compressed air (and ''only'' with a can of compressed air), dust that area and the surrounding area.&lt;br /&gt;
#Replace the small black plastic separator, then reconnect the keyboard.&lt;br /&gt;
#Slide the keyboard back into place, then press down on the Fn and right-arrow keys until it pops into place.&lt;br /&gt;
#Replace the keyboard screws and battery.&lt;br /&gt;
&lt;br /&gt;
==Dealing with spilling accidents==&lt;br /&gt;
#Don't panic.&lt;br /&gt;
#Don't flip or tilt the computer to prevent the liquid from spreading all over the inside of the case.&lt;br /&gt;
#Shut down the OS and turn off the power:&lt;br /&gt;
##Unplug the computer.&lt;br /&gt;
##Remove the battery.&lt;br /&gt;
#Tilt the computer so that everything that leaked into the case can flow out the same way.&lt;br /&gt;
#Allow the computer to dry before switching it on again.&lt;br /&gt;
#For minor accidents this might already be sufficient. For major flooding you should either bring the computer to a dealer who knows how to open and clean it from inside. Or you can read the Hardware Maintenance Manual, open, clean, and dry the computer yourself. &lt;br /&gt;

==Recovering BIOS passwords==&lt;br /&gt;
Password recovery procedure for IBM ThinkPads&lt;br /&gt;
using R24RF08 and IBMpass&lt;br /&gt;
&lt;br /&gt;
'''1. Introduction.'''&lt;br /&gt;
&lt;br /&gt;
The IBM ThinkPad uses a small eeprom ([[AT24RF08|ATMEL 24RF08]]) to store different OEM&lt;br /&gt;
issues like serial number, UUID, etc. The supervisor password (SVP) is also stored in this eeprom.&lt;br /&gt;
The 24RF08 is not an ordinary eeprom: it features read protection, which the BIOS uses to lock down&lt;br /&gt;
access to the eeprom contents.  Also, the password is written in a special scan code, which needs to&lt;br /&gt;
be translated to ASCII to be of any use.&lt;br /&gt;
&lt;br /&gt;
To recover the password, one can use two different programs: R24RF08 (eeprom reader) and IBMpass&lt;br /&gt;
(password revealer) available at [http://www.allservice.ro http://www.allservice.ro]. Diagrams are included in the reader kit.&lt;br /&gt;
&lt;br /&gt;
Models for which R24RF08 and IBMpass are enough to recover the password: 240, 240X, 390E, 390X, 570, 570E,&lt;br /&gt;
600e, 600X, 770Z, A20m, A21e, A21m, a22m, A30, A30p, A31, A31p, G40, G41, R30, R31, R32, R40, R50, R51, &lt;br /&gt;
Transnote, T20, T21, T22, T23, T30, T40, T40p, T41, T41p, T42, T42p, X20, X21, X22, X23, X24, X30, X31, X40, X41.&lt;br /&gt;
&lt;br /&gt;
ThinkPads featuring TPCA technology (i.e. a [[Tpm|TPM trusted platform module chip]]), especially T4x, X3x, X4x need the W24RF08 eeprom writer program to complete the password recovery procedure, if the passphrase function is enabled in BIOS setup.&lt;br /&gt;
&lt;br /&gt;
Other models such as the 380XD or 600 use 24C01 or 93C46 eeproms, which can be read without special tools.&lt;br /&gt;
The method is the same like for the models based on 24RF08, only the software to dump the eeprom is different. &lt;br /&gt;
&lt;br /&gt;
Newer T43/T43p, R52, R60, T60/p, X60 and Z60 ThinkPads can be unlocked using PC8394 programming tools that consist in RPC8394 and WPC8394 (reader and writer for TPM chips). The software is available as well on [http://www.allservice.ro http://www.allservice.ro]. IBMpass 2.0 works for any TP model without exceptions.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
'''2. Locating the ATMEL 24RF08 eeprom. Soldering.'''&lt;br /&gt;
&lt;br /&gt;
No need to unsolder the 24RF08 eeprom, just solder 3 wires to SDA, SCL and GND pins of the&lt;br /&gt;
eeprom. There are two eeprom layouts (see interface schematics described bellow), corresponding to 8 pin or 14 pin eeproms. Locate the eeprom first according to your model (E.g. T20-23 and T30 have the eeprom underneath TP, and can be accessed by removing the RAM modules cover, no need to dismantle the laptop.) and solder the wires using a soldering iron with a fine tip. Also, you can use 0.15 -0.20 mm enamel coated wires or similar small diameter insulated wires. These wires will be connected later to the interface.&lt;br /&gt;
Tip: You can use clips to connect the wires or you can solder on the PCB traces leading to the&lt;br /&gt;
eeprom pins. Once again, be careful and double, triple check the soldering if necessary till you are positively sure you have done the right job. In case of applying too much solder, use flux-impregnated copper-braid &amp;quot;desoldering wick&amp;quot; - this works exceptionally well.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
'''3. Choose and build the interface.'''&lt;br /&gt;
&lt;br /&gt;
Since version 2.0, R24RF08 and W24RF08 (eeprom writer) are compatible with a wide range of eeprom programmers. By default, both programs set the COM port signals to use direct logic level to access I2C bus. We provide here 2 schematics that are relevant for direct logic signals and for inverse logic signals (simple-i2cprog.pdf and driven-i2cprog.pdf). Also, depending of the interface you build, you can invert the logics for SDA-In, SDA-Out, and SCL COM port signals by some command line parameters described later in this document.&lt;br /&gt;
a) The file simple-i2cprog.pdf contains the schematic diagram of a simple interface (known as SIPROG)based on 2 zeners and 2 resistors. This is a classic, easy to build circuit and works with soldered or unsoldered eeproms. The purpose of the 2 zeners is to convert RS232 levels (+/- 5V) to TTL levels, needed by the eeprom. It uses direct logic signals to I2C eeprom and is powered by the COM port. However, this interface works with in-system eeproms but is dependant on COM port current and eeprom bus impedance. R24RF08 works natively with this circuit, no need to change the lines signals with command line parameters. This circuit works pretty well with almost all ThinkPads series.&lt;br /&gt;
b) The second interface is described in driven-i2cprog.pdf. The circuit uses MAX 232 as a RS232 to TTL driver and its main purpose is to work with soldered eeproms. The advantage of MAX232 is the TTL outputs that are more reliable and more powerful when work with soldered, in-system eeproms (dependency free from the COM port current). Due of the internal inverters of MAX232 the interface responds to an inverse signal logic level. R24RF08 needs /x, /d, /i switches to be specified in the command line.&lt;br /&gt;
&lt;br /&gt;
What these switches mean:&lt;br /&gt;
/x - invert serial clock, also known as SCL;&lt;br /&gt;
/d - invert serial data output, also known as SDA-Out;&lt;br /&gt;
/i - invert serial data input, also known as SDA-In.&lt;br /&gt;
All those can be used in any combination to meet any interface specification.&lt;br /&gt;
&lt;br /&gt;
Note that the &amp;quot;standard&amp;quot; serial port programmer probably won't work with a USB-Serial adapter, but requires the full nominal voltage of a hardware serial port. [Example: the A22p's serial port works fine here.]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
'''4. Dump the EEPROM:'''&lt;br /&gt;
&lt;br /&gt;
Prepare your technician PC by connecting the interface to the COM1 port (donâ€™t connect the wires to eeprom yet). Turn on the ThinkPad and press F1 to enter BIOS Setup. When you are prompted for the password and thereâ€™s no other activity like HDD access or so, connect the wires (GND first!, SDA, SCL) to the corresponding wires from the interface (attached before to COM1) and execute R24RF08:&lt;br /&gt;
&lt;br /&gt;
-for SI-PROG interface (as described in 3.a above):&lt;br /&gt;
r24rf08.exe &amp;lt;filename.ext&amp;gt;. where filename.ext is the file where eeprom content will be stored.&lt;br /&gt;
Example: r24rf08 mytp.bin&lt;br /&gt;
&lt;br /&gt;
-for MAX232 driven I2C interface (as described in 3.b above):&lt;br /&gt;
r24rf08.exe &amp;lt;filename.ext&amp;gt; /x /d /i. where /x /d /i are command line parameters (switches) for this kind of interface.&lt;br /&gt;
Example: r24rf08 mytp2.bin /x /d /i&lt;br /&gt;
&lt;br /&gt;
Use exactly the instructed switches to avoid possible damages to your eeprom data!&lt;br /&gt;
The file should be created in the same folder. Finally, disconnect the wires (GND last!) and turn off the ThinkPad by pressing on/off switch.&lt;br /&gt;
&lt;br /&gt;
Dump the EEPROM data at least twice, and do a bytewise compare with `cmp`. Both files should be identical, and 1024 bytes long. Otherwise, you probably have a serial port problem.&lt;br /&gt;
&lt;br /&gt;
Note: the r24rf08.exe program automatically sets the serial port parameters. It also works fine with Wine under Linux - provided that a symlink (com1) exists in the .wine/dos_devices directory, and points to the /dev/ttySX for the actual serial port.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
'''5. Reveal the password.'''&lt;br /&gt;
&lt;br /&gt;
Now, you have the .bin file but you need to dump in scan code to retrieve the password. IBMpass 2.0 Lite is a free tool that will do the job. Just open the eeprom dump youâ€™ve created before and search for 0x330, 0x340 lines. The password is located on 0x338 (and 0x340 depending on model) in scan code. For 24C01 eeproms the password is located at 0x38, 0x40. If the password won't work for the very first time then your eeprom may use newer IBM scancodes. In this case switch to alternate scan codes to find it. For those who want quick answers the recommended version is IBMpass 1.1. Usage for IBMpass 1.1 (command line only):&lt;br /&gt;
&lt;br /&gt;
ibmpass mytp.bin â€“ use â€œ/aâ€ switch to see in alternate scan code if needed:&lt;br /&gt;
ibmpass mytp.bin /a&lt;br /&gt;
&lt;br /&gt;
For some old models like 570 or 770Z you need to execute the eeprom patcher first. This will reset the read protection on the password offset. To do that just execute patcher.exe before the reading operation, without rebooting the laptop:&lt;br /&gt;
&lt;br /&gt;
-for SI-PROG:&lt;br /&gt;
patcher.exe , then immediately&lt;br /&gt;
r24rf08.exe &amp;lt;filename.ext&amp;gt;&lt;br /&gt;
&lt;br /&gt;
-for Driven-I2C (Max232) you must insert the switches:&lt;br /&gt;
patcher.exe /x /d /i, then immediately&lt;br /&gt;
r24rf08.exe &amp;lt;filename.ext&amp;gt; /x /d /i&lt;br /&gt;
&lt;br /&gt;
W24RF08, the writer version, has included the complete APP reset operation you donâ€™t need to use patcher.&lt;br /&gt;
&lt;br /&gt;
Moreover, there are a new encrypting algos used with some new security chips (AT97SC3201, AT97SC3203) that are very secured. The password is not in scancode and in some cases not even in the eeprom. To unlock the machine, the dump should suffer some changes and the eeprom must be reprogrammed using W24RF08. This operation works for all IBM TCG/TCPA secured laptops w/o exceptions. &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Remember, use 3 wires from the interface and 3 wires from eeprom! Connect them after your&lt;br /&gt;
ThinkPad is powered and disconnect them right after you read the content, before you switch off the laptop.&lt;br /&gt;
&lt;br /&gt;
'''6. Password format'''&lt;br /&gt;
&lt;br /&gt;
The thinkpad power-on/supervisor passwords are a maximum of 7 characters, and are NOT case-sensitive. The allowed characters are restricted to A-Z, 0-9, semicolon, _, - (and perhaps a few others).&lt;br /&gt;

&lt;br /&gt;
===Battery health===&lt;br /&gt;
Batteries, especially of the modern Li-Ion type, wear out quicker when they hold a large charge or are subject to higher temperatures (see above).&lt;br /&gt;
&lt;br /&gt;
If you use your laptop at a desk, reduce battery wear by maintaining an appropriate charge level.  When  possible, remove Li-ion batteries while operating from AC as the notebook gets hot enough inside for that to damage the battery in the long run, even if charging is stopped.&lt;br /&gt;
&lt;br /&gt;
On recent ThinkPads, charging thresholds can be configured in the bundled software.  Under Linux, this is supported on recent models by the [[tp_smapi]] driver (and even without &amp;lt;tt&amp;gt;tp_smapi&amp;lt;/tt&amp;gt;, if you have a dual-boot setup, you can set the thresholds under Windows and they will be remembered as long as you don't power off your machine with AC disconnected; suspend to RAM is OK). Have a look at [[How to use UltraBay batteries]].&lt;br /&gt;
&lt;br /&gt;
If you have spare Li-ion battery packs, store them at 40% charge in a cool place (15C being a recommended temperature, do not let the batteries freeze).  If storing inside a refrigerator, beware of humidity, and be careful with cold spots that can easily freeze the battery if anything goes wrong.&lt;br /&gt;
&lt;br /&gt;
===The problem with 600 series batteries===&lt;br /&gt;
ThinkPad 600 power management causes batteries to die before they should. Read more about this on the [[Problem with ThinkPad 600 batteries|associated problem page]].&lt;br /&gt;
&lt;br /&gt;
===Reviving batteries===&lt;br /&gt;
Some people experience sudden drops in their batteries capacity.  A way to get these batteries back to full capacity is to run the &amp;quot;Battery Rundown&amp;quot; function of IBMs &amp;quot;PC Doctor for DOS&amp;quot;.  The program is downloadable from IBMs support site as three floppy disk images.  Make sure you get the specific version of program made for your ThinkPad model.  For those who do not have a floppy, David Smith prepared a [http://www.mypchelp.com/~dsmith/ibmutil/ibm_t22_pcdiag.iso bootable CD image] (dead link, a copy is also available [http://server6.org/~marker/software/ibm_t22_pcdiag.iso here]) from the T22 floppy images. For newer ThinkPads there is an official [http://www-307.ibm.com/pc/support/site.wss/document.do?sitestyle=lenovo&amp;amp;lndocid=MIGR-56222 bootable CD image].&lt;br /&gt;
&lt;br /&gt;
I have recently made a discovery which could be considered, I have an R40 and two main batteries, both of them have aproximately about under 200 cycles and are nowadays 4 years old, projected capacity for R40/R32 main battery is 57Wh, and both my batteries were about 30Wh, than I left my notebook with one of them about a day in a standby mode, as long as it powered off itself because of low battery power, when I turned it on I saw the battery capacity at about 42Wh, than, I did this too for the second battery and I got even about 46Wh, I think I could go even higher with letting the battery discharge completely from 100% in standby, I think this has something to do with low power consumption in standby mode, it may work for you too.&lt;br /&gt;

==Cleaning the Interior==&lt;br /&gt;
{{WARN|The following instructions are not appropriate for all ThinkPad models. Please consult the hardware maintenance guide or on-line disassembly instructions for your model.}}&lt;br /&gt;
Most ThinkPad models (particularly the A-series and the T-series) tend to accumulate a lot of interior dust which they draw from their ventilation fan.  A good dusting every few months is advised. The procedure is as follows.&lt;br /&gt;
&lt;br /&gt;
===ThinkPad T4x series===&lt;br /&gt;

===Other models (which?)===&lt;br /&gt;
#Unplug the computer.&lt;br /&gt;
#Remove the battery.&lt;br /&gt;
#Turn the ThinkPad over and find two to three screws with upraised double-arrows pointing to them.&lt;br /&gt;
#Unscrew these screws and set them aside.&lt;br /&gt;
#Press the silver area underneath where the battery used to be.  The front of the keyboard will pop up.&lt;br /&gt;
#Turn the ThinkPad right side up and gently remove the keyboard, pulling it toward you.&lt;br /&gt;
#There is one connector between the ThinkPad and the keyboard.  Disconnect it, and set the keyboard aside.&lt;br /&gt;
#If there is a small black plastic separator under the keyboard, remove it and set it aside.&lt;br /&gt;
#The fan should be visible in the upper left.  That entire area will likely be dusty.  With a can of compressed air (and ''only'' with a can of compressed air), dust that area and the surrounding area.&lt;br /&gt;
#Replace the small black plastic separator, then reconnect the keyboard.&lt;br /&gt;
#Slide the keyboard back into place, then press down on the Fn and right-arrow keys until it pops into place.&lt;br /&gt;
#Replace the keyboard screws and battery.&lt;br /&gt;
&lt;br /&gt;
==Dealing with spilling accidents==&lt;br /&gt;
#Don't panic.&lt;br /&gt;
#Don't flip or tilt the computer to prevent the liquid from spreading all over the inside of the case.&lt;br /&gt;
#Shut down the OS and turn off the power:&lt;br /&gt;
##Unplug the computer.&lt;br /&gt;
##Remove the battery.&lt;br /&gt;
#Tilt the computer so that everything that leaked into the case can flow out the same way.&lt;br /&gt;
#Allow the computer to dry before switching it on again.&lt;br /&gt;
#For minor accidents this might already be sufficient. For major flooding you should either bring the computer to a dealer who knows how to open and clean it from inside. Or you can read the Hardware Maintenance Manual, open, clean, and dry the computer yourself. &lt;br /&gt;

==Recovering BIOS passwords==&lt;br /&gt;
Password recovery procedure for IBM ThinkPads&lt;br /&gt;
using R24RF08 and IBMpass&lt;br /&gt;
&lt;br /&gt;
'''1. Introduction.'''&lt;br /&gt;
&lt;br /&gt;
The IBM ThinkPad uses a small eeprom ([[AT24RF08|ATMEL 24RF08]]) to store different OEM&lt;br /&gt;
issues like serial number, UUID, etc. The supervisor password (SVP) is also stored in this eeprom.&lt;br /&gt;
The 24RF08 is not an ordinary eeprom: it features read protection, which the BIOS uses to lock down&lt;br /&gt;
access to the eeprom contents.  Also, the password is written in a special scan code, which needs to&lt;br /&gt;
be translated to ASCII to be of any use.&lt;br /&gt;
&lt;br /&gt;
To recover the password, one can use two different programs: R24RF08 (eeprom reader) and IBMpass&lt;br /&gt;
(password revealer) available at [http://www.allservice.ro http://www.allservice.ro]. Diagrams are included in the reader kit.&lt;br /&gt;
&lt;br /&gt;
Models for which R24RF08 and IBMpass are enough to recover the password: 240, 240X, 390E, 390X, 570, 570E,&lt;br /&gt;
600e, 600X, 770Z, A20m, A21e, A21m, a22m, A30, A30p, A31, A31p, G40, G41, R30, R31, R32, R40, R50, R51, &lt;br /&gt;
Transnote, T20, T21, T22, T23, T30, T40, T40p, T41, T41p, T42, T42p, X20, X21, X22, X23, X24, X30, X31, X40, X41.&lt;br /&gt;
&lt;br /&gt;
ThinkPads featuring TPCA technology (i.e. a [[Tpm|TPM trusted platform module chip]]), especially T4x, X3x, X4x need the W24RF08 eeprom writer program to complete the password recovery procedure, if the passphrase function is enabled in BIOS setup.&lt;br /&gt;
&lt;br /&gt;
Other models such as the 380XD or 600 use 24C01 or 93C46 eeproms, which can be read without special tools.&lt;br /&gt;
The method is the same like for the models based on 24RF08, only the software to dump the eeprom is different. &lt;br /&gt;
&lt;br /&gt;
Newer T43/T43p, R52, R60, T60/p, X60 and Z60 ThinkPads can be unlocked using PC8394 programming tools that consist in RPC8394 and WPC8394 (reader and writer for TPM chips). The software is available as well on [http://www.allservice.ro http://www.allservice.ro]. IBMpass 2.0 works for any TP model without exceptions.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
'''2. Locating the ATMEL 24RF08 eeprom. Soldering.'''&lt;br /&gt;
&lt;br /&gt;
No need to unsolder the 24RF08 eeprom, just solder 3 wires to SDA, SCL and GND pins of the&lt;br /&gt;
eeprom. There are two eeprom layouts (see interface schematics described bellow), corresponding to 8 pin or 14 pin eeproms. Locate the eeprom first according to your model (E.g. T20-23 and T30 have the eeprom underneath TP, and can be accessed by removing the RAM modules cover, no need to dismantle the laptop.) and solder the wires using a soldering iron with a fine tip. Also, you can use 0.15 -0.20 mm enamel coated wires or similar small diameter insulated wires. These wires will be connected later to the interface.&lt;br /&gt;
Tip: You can use clips to connect the wires or you can solder on the PCB traces leading to the&lt;br /&gt;
eeprom pins. Once again, be careful and double, triple check the soldering if necessary till you are positively sure you have done the right job. In case of applying too much solder, use flux-impregnated copper-braid &amp;quot;desoldering wick&amp;quot; - this works exceptionally well.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
'''3. Choose and build the interface.'''&lt;br /&gt;
&lt;br /&gt;
Since version 2.0, R24RF08 and W24RF08 (eeprom writer) are compatible with a wide range of eeprom programmers. By default, both programs set the COM port signals to use direct logic level to access I2C bus. We provide here 2 schematics that are relevant for direct logic signals and for inverse logic signals (simple-i2cprog.pdf and driven-i2cprog.pdf). Also, depending of the interface you build, you can invert the logics for SDA-In, SDA-Out, and SCL COM port signals by some command line parameters described later in this document.&lt;br /&gt;
a) The file simple-i2cprog.pdf contains the schematic diagram of a simple interface (known as SIPROG)based on 2 zeners and 2 resistors. This is a classic, easy to build circuit and works with soldered or unsoldered eeproms. The purpose of the 2 zeners is to convert RS232 levels (+/- 5V) to TTL levels, needed by the eeprom. It uses direct logic signals to I2C eeprom and is powered by the COM port. However, this interface works with in-system eeproms but is dependant on COM port current and eeprom bus impedance. R24RF08 works natively with this circuit, no need to change the lines signals with command line parameters. This circuit works pretty well with almost all ThinkPads series.&lt;br /&gt;
b) The second interface is described in driven-i2cprog.pdf. The circuit uses MAX 232 as a RS232 to TTL driver and its main purpose is to work with soldered eeproms. The advantage of MAX232 is the TTL outputs that are more reliable and more powerful when work with soldered, in-system eeproms (dependency free from the COM port current). Due of the internal inverters of MAX232 the interface responds to an inverse signal logic level. R24RF08 needs /x, /d, /i switches to be specified in the command line.&lt;br /&gt;
&lt;br /&gt;
What these switches mean:&lt;br /&gt;
/x - invert serial clock, also known as SCL;&lt;br /&gt;
/d - invert serial data output, also known as SDA-Out;&lt;br /&gt;
/i - invert serial data input, also known as SDA-In.&lt;br /&gt;
All those can be used in any combination to meet any interface specification.&lt;br /&gt;
&lt;br /&gt;
Note that the &amp;quot;standard&amp;quot; serial port programmer probably won't work with a USB-Serial adapter, but requires the full nominal voltage of a hardware serial port. [Example: the A22p's serial port works fine here.]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
'''4. Dump the EEPROM:'''&lt;br /&gt;
&lt;br /&gt;
Prepare your technician PC by connecting the interface to the COM1 port (donâ€™t connect the wires to eeprom yet). Turn on the ThinkPad and press F1 to enter BIOS Setup. When you are prompted for the password and thereâ€™s no other activity like HDD access or so, connect the wires (GND first!, SDA, SCL) to the corresponding wires from the interface (attached before to COM1) and execute R24RF08:&lt;br /&gt;
&lt;br /&gt;
-for SI-PROG interface (as described in 3.a above):&lt;br /&gt;
r24rf08.exe &amp;lt;filename.ext&amp;gt;. where filename.ext is the file where eeprom content will be stored.&lt;br /&gt;
Example: r24rf08 mytp.bin&lt;br /&gt;
&lt;br /&gt;
-for MAX232 driven I2C interface (as described in 3.b above):&lt;br /&gt;
r24rf08.exe &amp;lt;filename.ext&amp;gt; /x /d /i. where /x /d /i are command line parameters (switches) for this kind of interface.&lt;br /&gt;
Example: r24rf08 mytp2.bin /x /d /i&lt;br /&gt;
&lt;br /&gt;
Use exactly the instructed switches to avoid possible damages to your eeprom data!&lt;br /&gt;
The file should be created in the same folder. Finally, disconnect the wires (GND last!) and turn off the ThinkPad by pressing on/off switch.&lt;br /&gt;
&lt;br /&gt;
Dump the EEPROM data at least twice, and do a bytewise compare with `cmp`. Both files should be identical, and 1024 bytes long. Otherwise, you probably have a serial port problem.&lt;br /&gt;
&lt;br /&gt;
Note: the r24rf08.exe program automatically sets the serial port parameters. It also works fine with Wine under Linux - provided that a symlink (com1) exists in the .wine/dos_devices directory, and points to the /dev/ttySX for the actual serial port.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
'''5. Reveal the password.'''&lt;br /&gt;
&lt;br /&gt;
Now, you have the .bin file but you need to dump in scan code to retrieve the password. IBMpass 2.0 Lite is a free tool that will do the job. Just open the eeprom dump youâ€™ve created before and search for 0x330, 0x340 lines. The password is located on 0x338 (and 0x340 depending on model) in scan code. For 24C01 eeproms the password is located at 0x38, 0x40. If the password won't work for the very first time then your eeprom may use newer IBM scancodes. In this case switch to alternate scan codes to find it. For those who want quick answers the recommended version is IBMpass 1.1. Usage for IBMpass 1.1 (command line only):&lt;br /&gt;
&lt;br /&gt;
ibmpass mytp.bin â€“ use â€œ/aâ€ switch to see in alternate scan code if needed:&lt;br /&gt;
ibmpass mytp.bin /a&lt;br /&gt;
&lt;br /&gt;
For some old models like 570 or 770Z you need to execute the eeprom patcher first. This will reset the read protection on the password offset. To do that just execute patcher.exe before the reading operation, without rebooting the laptop:&lt;br /&gt;
&lt;br /&gt;
-for SI-PROG:&lt;br /&gt;
patcher.exe , then immediately&lt;br /&gt;
r24rf08.exe &amp;lt;filename.ext&amp;gt;&lt;br /&gt;
&lt;br /&gt;
-for Driven-I2C (Max232) you must insert the switches:&lt;br /&gt;
patcher.exe /x /d /i, then immediately&lt;br /&gt;
r24rf08.exe &amp;lt;filename.ext&amp;gt; /x /d /i&lt;br /&gt;
&lt;br /&gt;
W24RF08, the writer version, has included the complete APP reset operation you donâ€™t need to use patcher.&lt;br /&gt;
&lt;br /&gt;
Moreover, there are a new encrypting algos used with some new security chips (AT97SC3201, AT97SC3203) that are very secured. The password is not in scancode and in some cases not even in the eeprom. To unlock the machine, the dump should suffer some changes and the eeprom must be reprogrammed using W24RF08. This operation works for all IBM TCG/TCPA secured laptops w/o exceptions. &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Remember, use 3 wires from the interface and 3 wires from eeprom! Connect them after your&lt;br /&gt;
ThinkPad is powered and disconnect them right after you read the content, before you switch off the laptop.&lt;br /&gt;
&lt;br /&gt;
'''6. Password format'''&lt;br /&gt;
&lt;br /&gt;
The thinkpad power-on/supervisor passwords are a maximum of 7 characters, and are NOT case-sensitive. The allowed characters are restricted to A-Z, 0-9, semicolon, _, - (and perhaps a few others).&lt;br /&gt;

&lt;br /&gt;
===Battery health===&lt;br /&gt;
Batteries, especially of the modern Li-Ion type, wear out quicker when they hold a large charge or are subject to higher temperatures (see above).&lt;br /&gt;
&lt;br /&gt;
If you use your laptop at a desk, reduce battery wear by maintaining an appropriate charge level.  When  possible, remove Li-ion batteries while operating from AC as the notebook gets hot enough inside for that to damage the battery in the long run, even if charging is stopped.&lt;br /&gt;
&lt;br /&gt;
On recent ThinkPads, charging thresholds can be configured in the bundled software.  Under Linux, this is supported on recent models by the [[tp_smapi]] driver (and even without &amp;lt;tt&amp;gt;tp_smapi&amp;lt;/tt&amp;gt;, if you have a dual-boot setup, you can set the thresholds under Windows and they will be remembered as long as you don't power off your machine with AC disconnected; suspend to RAM is OK). Have a look at [[How to use UltraBay batteries]].&lt;br /&gt;
&lt;br /&gt;
If you have spare Li-ion battery packs, store them at 40% charge in a cool place (15C being a recommended temperature, do not let the batteries freeze).  If storing inside a refrigerator, beware of humidity, and be careful with cold spots that can easily freeze the battery if anything goes wrong.&lt;br /&gt;
&lt;br /&gt;
===The problem with 600 series batteries===&lt;br /&gt;
ThinkPad 600 power management causes batteries to die before they should. Read more about this on the [[Problem with ThinkPad 600 batteries|associated problem page]].&lt;br /&gt;
&lt;br /&gt;
===Reviving batteries===&lt;br /&gt;
Some people experience sudden drops in their batteries capacity.  A way to get these batteries back to full capacity is to run the &amp;quot;Battery Rundown&amp;quot; function of IBMs &amp;quot;PC Doctor for DOS&amp;quot;.  The program is downloadable from IBMs support site as three floppy disk images.  Make sure you get the specific version of program made for your ThinkPad model.  For those who do not have a floppy, David Smith prepared a [http://www.mypchelp.com/~dsmith/ibmutil/ibm_t22_pcdiag.iso bootable CD image] (dead link, a copy is also available [http://server6.org/~marker/software/ibm_t22_pcdiag.iso here]) from the T22 floppy images. For newer ThinkPads there is an official [http://www-307.ibm.com/pc/support/site.wss/document.do?sitestyle=lenovo&amp;amp;lndocid=MIGR-56222 bootable CD image].&lt;br /&gt;
&lt;br /&gt;
I have recently made a discovery which could be considered, I have an R40 and two main batteries, each of them have aproximately about under 200 cycles and are nowadays 4 years old, projected capacity for R40/R32 main battery is 57Wh, and both my batteries were about 30Wh, than I left my notebook with one of them about a day in a standby mode, as long as it powered off itself because of low battery power, when I turned it on I saw the battery capacity at about 42Wh, than, I did this too for the second battery and I got even about 46Wh, I think I could go even higher with letting the battery discharge completely from 100% in standby, I think this has something to do with low power consumption in standby mode, it may work for you too.&lt;br /&gt;

==Cleaning the Interior==&lt;br /&gt;
{{WARN|The following instructions are not appropriate for all ThinkPad models. Please consult the hardware maintenance guide or on-line disassembly instructions for your model.}}&lt;br /&gt;
Most ThinkPad models (particularly the A-series and the T-series) tend to accumulate a lot of interior dust which they draw from their ventilation fan.  A good dusting every few months is advised. The procedure is as follows.&lt;br /&gt;
&lt;br /&gt;

===Other models (which?)===&lt;br /&gt;
#Unplug the computer.&lt;br /&gt;
#Remove the battery.&lt;br /&gt;
#Turn the ThinkPad over and find two to three screws with upraised double-arrows pointing to them.&lt;br /&gt;
#Unscrew these screws and set them aside.&lt;br /&gt;
#Press the silver area underneath where the battery used to be.  The front of the keyboard will pop up.&lt;br /&gt;
#Turn the ThinkPad right side up and gently remove the keyboard, pulling it toward you.&lt;br /&gt;
#There is one connector between the ThinkPad and the keyboard.  Disconnect it, and set the keyboard aside.&lt;br /&gt;
#If there is a small black plastic separator under the keyboard, remove it and set it aside.&lt;br /&gt;
#The fan should be visible in the upper left.  That entire area will likely be dusty.  With a can of compressed air (and ''only'' with a can of compressed air), dust that area and the surrounding area.&lt;br /&gt;
#Replace the small black plastic separator, then reconnect the keyboard.&lt;br /&gt;
#Slide the keyboard back into place, then press down on the Fn and right-arrow keys until it pops into place.&lt;br /&gt;
#Replace the keyboard screws and battery.&lt;br /&gt;
&lt;br /&gt;
==Dealing with spilling accidents==&lt;br /&gt;
#Don't panic.&lt;br /&gt;
#Don't flip or tilt the computer to prevent the liquid from spreading all over the inside of the case.&lt;br /&gt;
#Shut down the OS and turn off the power:&lt;br /&gt;
##Unplug the computer.&lt;br /&gt;
##Remove the battery.&lt;br /&gt;
#Tilt the computer so that everything that leaked into the case can flow out the same way.&lt;br /&gt;
#Allow the computer to dry before switching it on again.&lt;br /&gt;
#For minor accidents this might already be sufficient. For major flooding you should either bring the computer to a dealer who knows how to open and clean it from inside. Or you can read the Hardware Maintenance Manual, open, clean, and dry the computer yourself. &lt;br /&gt;

==Recovering BIOS passwords==&lt;br /&gt;
Password recovery procedure for IBM ThinkPads&lt;br /&gt;
using R24RF08 and IBMpass&lt;br /&gt;
&lt;br /&gt;
'''1. Introduction.'''&lt;br /&gt;
&lt;br /&gt;
The IBM ThinkPad uses a small eeprom ([[AT24RF08|ATMEL 24RF08]]) to store different OEM&lt;br /&gt;
issues like serial number, UUID, etc. The supervisor password (SVP) is also stored in this eeprom.&lt;br /&gt;
The 24RF08 is not an ordinary eeprom: it features read protection, which the BIOS uses to lock down&lt;br /&gt;
access to the eeprom contents.  Also, the password is written in a special scan code, which needs to&lt;br /&gt;
be translated to ASCII to be of any use.&lt;br /&gt;
&lt;br /&gt;
To recover the password, one can use two different programs: R24RF08 (eeprom reader) and IBMpass&lt;br /&gt;
(password revealer) available at [http://www.allservice.ro http://www.allservice.ro]. Diagrams are included in the reader kit.&lt;br /&gt;
&lt;br /&gt;
Models for which R24RF08 and IBMpass are enough to recover the password: 240, 240X, 390E, 390X, 570, 570E,&lt;br /&gt;
600e, 600X, 770Z, A20m, A21e, A21m, a22m, A30, A30p, A31, A31p, G40, G41, R30, R31, R32, R40, R50, R51, &lt;br /&gt;
Transnote, T20, T21, T22, T23, T30, T40, T40p, T41, T41p, T42, T42p, X20, X21, X22, X23, X24, X30, X31, X40, X41.&lt;br /&gt;
&lt;br /&gt;
ThinkPads featuring TPCA technology (i.e. a [[Tpm|TPM trusted platform module chip]]), especially T4x, X3x, X4x need the W24RF08 eeprom writer program to complete the password recovery procedure, if the passphrase function is enabled in BIOS setup.&lt;br /&gt;
&lt;br /&gt;
Other models such as the 380XD or 600 use 24C01 or 93C46 eeproms, which can be read without special tools.&lt;br /&gt;
The method is the same like for the models based on 24RF08, only the software to dump the eeprom is different. &lt;br /&gt;
&lt;br /&gt;
Newer T43/T43p, R52, R60, T60/p, X60 and Z60 ThinkPads can be unlocked using PC8394 programming tools that consist in RPC8394 and WPC8394 (reader and writer for TPM chips). The software is available as well on [http://www.allservice.ro http://www.allservice.ro]. IBMpass 2.0 works for any TP model without exceptions.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
'''2. Locating the ATMEL 24RF08 eeprom. Soldering.'''&lt;br /&gt;
&lt;br /&gt;
No need to unsolder the 24RF08 eeprom, just solder 3 wires to SDA, SCL and GND pins of the&lt;br /&gt;
eeprom. There are two eeprom layouts (see interface schematics described bellow), corresponding to 8 pin or 14 pin eeproms. Locate the eeprom first according to your model (E.g. T20-23 and T30 have the eeprom underneath TP, and can be accessed by removing the RAM modules cover, no need to dismantle the laptop.) and solder the wires using a soldering iron with a fine tip. Also, you can use 0.15 -0.20 mm enamel coated wires or similar small diameter insulated wires. These wires will be connected later to the interface.&lt;br /&gt;
Tip: You can use clips to connect the wires or you can solder on the PCB traces leading to the&lt;br /&gt;
eeprom pins. Once again, be careful and double, triple check the soldering if necessary till you are positively sure you have done the right job. In case of applying too much solder, use flux-impregnated copper-braid &amp;quot;desoldering wick&amp;quot; - this works exceptionally well.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
'''3. Choose and build the interface.'''&lt;br /&gt;
&lt;br /&gt;
Since version 2.0, R24RF08 and W24RF08 (eeprom writer) are compatible with a wide range of eeprom programmers. By default, both programs set the COM port signals to use direct logic level to access I2C bus. We provide here 2 schematics that are relevant for direct logic signals and for inverse logic signals (simple-i2cprog.pdf and driven-i2cprog.pdf). Also, depending of the interface you build, you can invert the logics for SDA-In, SDA-Out, and SCL COM port signals by some command line parameters described later in this document.&lt;br /&gt;
a) The file simple-i2cprog.pdf contains the schematic diagram of a simple interface (known as SIPROG)based on 2 zeners and 2 resistors. This is a classic, easy to build circuit and works with soldered or unsoldered eeproms. The purpose of the 2 zeners is to convert RS232 levels (+/- 5V) to TTL levels, needed by the eeprom. It uses direct logic signals to I2C eeprom and is powered by the COM port. However, this interface works with in-system eeproms but is dependant on COM port current and eeprom bus impedance. R24RF08 works natively with this circuit, no need to change the lines signals with command line parameters. This circuit works pretty well with almost all ThinkPads series.&lt;br /&gt;
b) The second interface is described in driven-i2cprog.pdf. The circuit uses MAX 232 as a RS232 to TTL driver and its main purpose is to work with soldered eeproms. The advantage of MAX232 is the TTL outputs that are more reliable and more powerful when work with soldered, in-system eeproms (dependency free from the COM port current). Due of the internal inverters of MAX232 the interface responds to an inverse signal logic level. R24RF08 needs /x, /d, /i switches to be specified in the command line.&lt;br /&gt;
&lt;br /&gt;
What these switches mean:&lt;br /&gt;
/x - invert serial clock, also known as SCL;&lt;br /&gt;
/d - invert serial data output, also known as SDA-Out;&lt;br /&gt;
/i - invert serial data input, also known as SDA-In.&lt;br /&gt;
All those can be used in any combination to meet any interface specification.&lt;br /&gt;
&lt;br /&gt;
Note that the &amp;quot;standard&amp;quot; serial port programmer probably won't work with a USB-Serial adapter, but requires the full nominal voltage of a hardware serial port. [Example: the A22p's serial port works fine here.]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
'''4. Dump the EEPROM:'''&lt;br /&gt;
&lt;br /&gt;
Prepare your technician PC by connecting the interface to the COM1 port (donâ€™t connect the wires to eeprom yet). Turn on the ThinkPad and press F1 to enter BIOS Setup. When you are prompted for the password and thereâ€™s no other activity like HDD access or so, connect the wires (GND first!, SDA, SCL) to the corresponding wires from the interface (attached before to COM1) and execute R24RF08:&lt;br /&gt;
&lt;br /&gt;
-for SI-PROG interface (as described in 3.a above):&lt;br /&gt;
r24rf08.exe &amp;lt;filename.ext&amp;gt;. where filename.ext is the file where eeprom content will be stored.&lt;br /&gt;
Example: r24rf08 mytp.bin&lt;br /&gt;
&lt;br /&gt;
-for MAX232 driven I2C interface (as described in 3.b above):&lt;br /&gt;
r24rf08.exe &amp;lt;filename.ext&amp;gt; /x /d /i. where /x /d /i are command line parameters (switches) for this kind of interface.&lt;br /&gt;
Example: r24rf08 mytp2.bin /x /d /i&lt;br /&gt;
&lt;br /&gt;
Use exactly the instructed switches to avoid possible damages to your eeprom data!&lt;br /&gt;
The file should be created in the same folder. Finally, disconnect the wires (GND last!) and turn off the ThinkPad by pressing on/off switch.&lt;br /&gt;
&lt;br /&gt;
Dump the EEPROM data at least twice, and do a bytewise compare with `cmp`. Both files should be identical, and 1024 bytes long. Otherwise, you probably have a serial port problem.&lt;br /&gt;
&lt;br /&gt;
Note: the r24rf08.exe program automatically sets the serial port parameters. It also works fine with Wine under Linux - provided that a symlink (com1) exists in the .wine/dos_devices directory, and points to the /dev/ttySX for the actual serial port.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
'''5. Reveal the password.'''&lt;br /&gt;
&lt;br /&gt;
Now, you have the .bin file but you need to dump in scan code to retrieve the password. IBMpass 2.0 Lite is a free tool that will do the job. Just open the eeprom dump youâ€™ve created before and search for 0x330, 0x340 lines. The password is located on 0x338 (and 0x340 depending on model) in scan code. For 24C01 eeproms the password is located at 0x38, 0x40. If the password won't work for the very first time then your eeprom may use newer IBM scancodes. In this case switch to alternate scan codes to find it. For those who want quick answers the recommended version is IBMpass 1.1. Usage for IBMpass 1.1 (command line only):&lt;br /&gt;
&lt;br /&gt;
ibmpass mytp.bin â€“ use â€œ/aâ€ switch to see in alternate scan code if needed:&lt;br /&gt;
ibmpass mytp.bin /a&lt;br /&gt;
&lt;br /&gt;
For some old models like 570 or 770Z you need to execute the eeprom patcher first. This will reset the read protection on the password offset. To do that just execute patcher.exe before the reading operation, without rebooting the laptop:&lt;br /&gt;
&lt;br /&gt;
-for SI-PROG:&lt;br /&gt;
patcher.exe , then immediately&lt;br /&gt;
r24rf08.exe &amp;lt;filename.ext&amp;gt;&lt;br /&gt;
&lt;br /&gt;
-for Driven-I2C (Max232) you must insert the switches:&lt;br /&gt;
patcher.exe /x /d /i, then immediately&lt;br /&gt;
r24rf08.exe &amp;lt;filename.ext&amp;gt; /x /d /i&lt;br /&gt;
&lt;br /&gt;
W24RF08, the writer version, has included the complete APP reset operation you donâ€™t need to use patcher.&lt;br /&gt;
&lt;br /&gt;
Moreover, there are a new encrypting algos used with some new security chips (AT97SC3201, AT97SC3203) that are very secured. The password is not in scancode and in some cases not even in the eeprom. To unlock the machine, the dump should suffer some changes and the eeprom must be reprogrammed using W24RF08. This operation works for all IBM TCG/TCPA secured laptops w/o exceptions. &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Remember, use 3 wires from the interface and 3 wires from eeprom! Connect them after your&lt;br /&gt;
ThinkPad is powered and disconnect them right after you read the content, before you switch off the laptop.&lt;br /&gt;
&lt;br /&gt;
'''6. Password format'''&lt;br /&gt;
&lt;br /&gt;
The thinkpad power-on/supervisor passwords are a maximum of 7 characters, and are NOT case-sensitive. The allowed characters are restricted to A-Z, 0-9, semicolon, _, - (and perhaps a few others).&lt;br /&gt;
