Talk:Problem with DVI throughput

2008-10-20T07:18:41Z

Maccess: /* Latest IBM Drivers Don't Support 1600x1200 on all models */

Here's some information I found:

Most DVI devices today use single-link DVI which supports a maximum bandwidth of 165 MHz [http://www.ddwg.org/dvi.html]. I suppose that ThinkPads provide a single-link DVI signal.

To calculate the bandwidth of your signal, in theory you just need to multiply the resolution with the vertical frequency. For example: 1600x1200 @ 85 Hz => 1600*1200*85 Hz = 163 MHz. This looks good, but it is outside the specs - because you need to take into account some extra time. CRTs need a so-called ''blanking time'' between the data for two display lines. This time is needed for something similar to a carriage return on a typewriter: The electron beam needs to be returned to the start of the next line. Additionally, some extra time is needed to transmit information about the border area around the real picture. About 25% of the bandwidth is used for these additional data. [http://graphics.tomshardware.com/graphic/20041129/tft_connection-04.html]

This means, that there is no specific ThinkPad problem with the throughput - you are just trying to transfer video data at a rate that is outside the specs of DVI. Maybe the DVI transmitter inside the ThinkPad even works at this data rate. But the DVI receiver inside the monitor might be "overclocked".

TFTs don't really need extra time. So there is a chance of writing a display driver with a reduced blanking time. This might explain, why some people were successful with other drivers.

The effective maximum resolution for single link DVI should be around 1600x1200 @ 65 Hz, or @ 60 Hz to be on the sure side. Has anyone solved his problems by lowering the vertical frequency?

== No problem on T41p ==

I have a T41p with 1400x1040 LCD and a Samsung SyncMaster 213T connected through the Port Replicator II with DVI<br>
After some windows registry hacks I can run the Samsung in 1600x1200 in single, clone display and extend display mode.<br>
Linux requires no such hacks and will happily run at 1600x1200

The picture through DVI is perfect with either desktop applications or running DVD video.

----
This is good news.
Do you run Linux in DualHead, MergedFB or CloneMode?
In Windows you have a clear video overlay all the time (like after every boot)?
Which drivers are you using in Linux and Windows, please list the with version numbers.

==Question about DVI/LCD switching on T4x / Radeon M9 / Linux==
Has anyone been able to successfully switch back and forth between the LCD output and the Port Replicator II DVI output on Linux? How do you do it? My problem is described below:

[[http://forums.gentoo.org/viewtopic-t-320973-highlight-.html]]

== No problems here ==

I installed the new catalyst drivers 5.6 using Patje's Mobility Moddingand it works for all resolutions. My laptop runs at 1400x1060 and my dvi screen at 1920x1200.
No problems that I can tell. The omega drivers (based on older catalyst drivers) blue screened my windows xp on boot.

Thanks for the info, it is a while since i tested with Catalyst and back then it didn't allow 1400x1050.

== Corruption and Flickering on T43 ==

No problems changing to 1600x1200 @60Hz on DVI passthrough using stock ATI drivers (6.14.10) and IBM presentation director on T43 and port replicator II. However the image is not stable - green dot artifacts flicker in approximately horizontal lines, while the screen blanks in and out. Completely stable at 1280x1024. Changing to the Omega drivers did not help at all. Also replacing ATI with Omega drivers somehow removed the presentation director key binding Fn-F7 and I had to reinstall it to get it back. Monitor is NEC AccuSync 200VX. Tried what appeared to be both single and dual-link DVI cables (not sure about monitor or port replicator support for dual-link).

I just tried the same setup while replacing the NEC monitor with a Planar PL2010M. The Planar LCD gives a completely stable image at 1600x1200.

UPDATE: I was able to get a stable 1600x1200 image on the NEC panel by going into the ATI Catalyst Control Center (downloadable as standalone program from ATI webpage) and <b>unchecking</b> "Reduce DVI frequency on high-resolution displays" which was on by default. The "Alternate DVI operational mode" option seems to have no effect either way. I'm guessing "Reduce DVI frequency" changes to 50 Hz or something, and "Aleternate DVI operational mode" is the reduced blanking time, but who knows with ATI's ambiguous descriptions. In any case it's interesting that the fixes mentioned on this page actually cause trouble on the NEC display, while taking away the "fixes" makes the problem go away.

--Aeyea

I have a T43 attached to a port replicator II 74P7633 and a pair of Samsung 213T 1600x1200 monitors attached, one each to the DVI and VGA ports on the dock. The built-in LCD is disabled when both externals are activated. I experienced that problem, but then downloaded the latest ATI Catalyst drivers and the Driver Heaven Mobility mod. I also switched off the "Alternate DVI operational mode" which fixed the DVI instability problem. I didn't have to reduce DVI frequency for the pair of monitors to run properly.

On a side note: I've also tried attaching my X22 to the same dock. Only the VGA monitor works together with the built-in LCD. I think the Radeon 7000 supports only dual VGA ports (one to the LCD, the other to the external). I tried connecting the second monitor to the laptop's VGA port but that didn't work. If I find a non-destructive hack to extract a second VGA signal (the one that drive the X22s built-in LCD), I'll post it here.

It's interesting, indeed, since it's quite illogical. Did you try the newest official IBM drivers? They worked out of the box for me and at least one other person. On a T41p with a NEC 2180UX that is. I think the "Reduce DVI frequency" changes to 60 Hz, which is supposed to be ideal for DVI TFTs, but that may in fact vary.

[[User:Wyrfel|Wyrfel]] 01:43, 27 Oct 2005 (CEST)

I haven't, as far as I know, tried the newest IBM drivers for the Radeon X300 - dated 2005-02-11 on Lenovo's website. I just did an install of ATI Catalyst 5.11 with the included control center. This installation actually requires a hack (http://www.driverheaven.net/patje/) for mobile devices. But in any case, the NEC LCD200VX still requires "Reduce DVI Frequency" to be unchecked in the ATI Control Center to avoid artifacts and instability. I would guess that the IBM drives also have this option enabled by default, so probably they would not work on this particular display without changing the settings, but I don't know for sure. I did take a look at the monitor's OSD info. In both cases, with and without "reduce DVI frequency" checked the OSD reports running at 1600x1200 at 75kHz horiz, 60Hz vertical. I'd really like to know what this setting does, then.

--[[User:Aeyea|Aeyea]] 21:07, 15 Nov 2005 (CET)

Funny thing I just discovered that having the option "Alternate DVI operational mode" enabled causes small artifacts on the NEC screen. These are little red and blue pixels or clusters of pixels that light up here and there - most visible on a totally black screen. So enabling the "Reduce DVI frequency" option causes screen blanking in and out (very disturbing), and enabling "Alternate DVI operational mode" causes small artifacts (almost unnoticeable).

== Single-link DVI ==

No thinkpads are currently capable of supporting dual-link DVI natively.

Single link is limited to 165MHz, while dual link has double that.

1600x1200x60=115200000Hz or 115.2MHz (assuming no blanking space), so in theory that should not be a problem, but in practice there might be additional limitations, such as the quality of the video controller and the passthrough to the dock or port replicator.

The IBM video drivers have always limited DVI output to 1280x1024, probably due to these issues.
Some people have had success hacking the drivers (or using alternative drivers), and going up to 1920x1200, but other people get corruption already at 1600x1200.

1920x1200x60=138240000Hz or 138.24MHz

== X40? ==
The article says the X40 is affected by this issue---how is that? Are there any X40 docs or adapters that give the X40 DVI capability at all?
----
The X4x and X6x series use Intel GMA Integrated Video without any DVI support. (that's the same problem with T4x with Intel Video). To get DVI support, you could try using Matrox DualHead2Go or TripleHead2Go to convert your single VGA output to two or three DVI outputs. Alternatively, you could get a Dock II and place a PCI DVI video card and use that, or you could use Villagetronic's Cardbus video card and use the DVI ouput.

== List of affected models is totally incorrect ==

Just because a ThinkPad is compatible with a Dock or Port Replicator that has a DVI port, does not mean you can actually use it.

For example, NONE of the T2x or X series ThinkPads can do DVI, and there are probably others.

== Latest IBM Drivers Don't Support 1600x1200 on all models ==

The latest ThinkPad video driver, 2005 Aug 11 release, version 8.133.2-050525a-024243C-IBM, does *not* appear
to support 1600x1200 mode on a T41 (not T41p) out of the box when using the MiniDock and an NEC 2080UX display.
The Display Properties->Setting tab allows 1600x1200 pixels to be selected, but the display is driven
at 1280x1024. Patched Catalyst drivers from ATI have been working just fine on the T41 for 1600x1200 with only a
few DVI driver issues (flying green pixels) on applications like Celestia.

As I have tested several T4Xp models, it seems that after T41p (like model 2373-GHG) the DVI throughput problem has been solved by IBM using latest drivers (video and presentation director) running Windows XP, however, my users have reported "flickering" on screens randomly (like Dell 20" and 24") and that seems to be solved by using better cables. Don't expect to be able to extend or use very long cables! ((Someone correct me if I'm wrong, but the T40p model has been making trouble for me.))

I have a t41 (Type 2373) non "P" and the Port Replicator II (74p6734)

With the ATI hydra drivers I can drive an Apple 23 inch at 1920x1200 but I cannot set it as the "primary Monitor" which I want to do. I keep the thinkpad and dock in my desk and do not want to even extend onto the notebook LCD.

Any ideas why cannot change the external display to be the "primary" monitor.

:I have a T43 (as mentioned above) attached to the Port Replicator II driving two 1600x1200 external LCDs through the VGA and DVI port. I can set the DVI to be the primary, but it resets everytime I use the laptop unattached to the dock. Eventually, I gave up and just use the monitor attached to VGA as primary. The VGA is to my left, the DVI is directly ahead of me. FYI, I was also able to set portrait mode--that works fine until the computer is used undocked--the ATI drivers have to be reinstalled.
[[User:Maccess|Maccess]] 06:08, 20 October 2008 (CEST)

FYI -- if I use my Village Tronic PCMCIA video card I can drive monitor as the primary display. However, the video performance of the Village tronic card is very limited and thus my desire to move to the port deplicator DVI connector.

Any ideas ???

Here's some information I found:

Most DVI devices today use single-link DVI which supports a maximum bandwidth of 165 MHz [http://www.ddwg.org/dvi.html]. I suppose that ThinkPads provide a single-link DVI signal.

To calculate the bandwidth of your signal, in theory you just need to multiply the resolution with the vertical frequency. For example: 1600x1200 @ 85 Hz => 1600*1200*85 Hz = 163 MHz. This looks good, but it is outside the specs - because you need to take into account some extra time. CRTs need a so-called ''blanking time'' between the data for two display lines. This time is needed for something similar to a carriage return on a typewriter: The electron beam needs to be returned to the start of the next line. Additionally, some extra time is needed to transmit information about the border area around the real picture. About 25% of the bandwidth is used for these additional data.

This means, that there is no specific ThinkPad problem with the throughput - you are just trying to transfer video data at a rate that is outside the specs of DVI. Maybe the DVI transmitter inside the ThinkPad even works at this data rate. But the DVI receiver inside the monitor might be "overclocked".

TFTs don't really need extra time. So there is a chance of writing a display driver with a reduced blanking time. This might explain, why some people were successful with other drivers.

The effective maximum resolution for single link DVI should be around 1600x1200 @ 65 Hz, or @ 60 Hz to be on the sure side. Has anyone solved his problems by lowering the vertical frequency?

==Question about DVI/LCD switching on T4x / Radeon M9 / Linux==
Has anyone been able to successfully switch back and forth between the LCD output and the Port Replicator II DVI output on Linux? How do you do it? My problem is described below:

[[http://forums.gentoo.org/viewtopic-t-320973-highlight-.html]]

== No problems here ==

I installed the new catalyst drivers 5.6 using Patje's Mobility Moddingand it works for all resolutions. My laptop runs at 1400x1060 and my dvi screen at 1920x1200.
No problems that I can tell. The omega drivers (based on older catalyst drivers) blue screened my windows xp on boot.

Thanks for the info, it is a while since i tested with Catalyst and back then it didn't allow 1400x1050.

== Corruption and Flickering on T43 ==

No problems changing to 1600x1200 @60Hz on DVI passthrough using stock ATI drivers (6.14.10) and IBM presentation director on T43 and port replicator II. However the image is not stable - green dot artifacts flicker in approximately horizontal lines, while the screen blanks in and out. Completely stable at 1280x1024. Changing to the Omega drivers did not help at all. Also replacing ATI with Omega drivers somehow removed the presentation director key binding Fn-F7 and I had to reinstall it to get it back. Monitor is NEC AccuSync 200VX. Tried what appeared to be both single and dual-link DVI cables (not sure about monitor or port replicator support for dual-link).

I just tried the same setup while replacing the NEC monitor with a Planar PL2010M. The Planar LCD gives a completely stable image at 1600x1200.

UPDATE: I was able to get a stable 1600x1200 image on the NEC panel by going into the ATI Catalyst Control Center (downloadable as standalone program from ATI webpage) and <b>unchecking</b> "Reduce DVI frequency on high-resolution displays" which was on by default. The "Alternate DVI operational mode" option seems to have no effect either way. I'm guessing "Reduce DVI frequency" changes to 50 Hz or something, and "Aleternate DVI operational mode" is the reduced blanking time, but who knows with ATI's ambiguous descriptions. In any case it's interesting that the fixes mentioned on this page actually cause trouble on the NEC display, while taking away the "fixes" makes the problem go away.

--Aeyea

I have a T43 attached to a port replicator II 74P7633 and a pair of Samsung 213T 1600x1200 monitors attached, one each to the DVI and VGA ports on the dock. The built-in LCD is disabled when both externals are activated. I experienced that problem, but then downloaded the latest ATI Catalyst drivers and the Driver Heaven Mobility mod. I also switched off the "Alternate DVI operational mode" which fixed the DVI instability problem. I didn't have to reduce DVI frequency for the pair of monitors to run properly.

On a side note: I've also tried attaching my X22 to the same dock. Only the VGA monitor works together with the built-in LCD. I think the Radeon 7000 supports only dual VGA ports (one to the LCD, the other to the external). I tried connecting the second monitor to the laptop's VGA port but that didn't work. If I find a non-destructive hack to extract a second VGA signal (the one that drive the X22s built-in LCD), I'll post it here.

It's interesting, indeed, since it's quite illogical. Did you try the newest official IBM drivers? They worked out of the box for me and at least one other person. On a T41p with a NEC 2180UX that is. I think the "Reduce DVI frequency" changes to 60 Hz, which is supposed to be ideal for DVI TFTs, but that may in fact vary.

[[User:Wyrfel|Wyrfel]] 01:43, 27 Oct 2005 (CEST)

I haven't, as far as I know, tried the newest IBM drivers for the Radeon X300 - dated 2005-02-11 on Lenovo's website. I just did an install of ATI Catalyst 5.11 with the included control center. This installation actually requires a hack (http://www.driverheaven.net/patje/) for mobile devices. But in any case, the NEC LCD200VX still requires "Reduce DVI Frequency" to be unchecked in the ATI Control Center to avoid artifacts and instability. I would guess that the IBM drives also have this option enabled by default, so probably they would not work on this particular display without changing the settings, but I don't know for sure. I did take a look at the monitor's OSD info. In both cases, with and without "reduce DVI frequency" checked the OSD reports running at 1600x1200 at 75kHz horiz, 60Hz vertical. I'd really like to know what this setting does, then.

--[[User:Aeyea|Aeyea]] 21:07, 15 Nov 2005 (CET)

Funny thing I just discovered that having the option "Alternate DVI operational mode" enabled causes small artifacts on the NEC screen. These are little red and blue pixels or clusters of pixels that light up here and there - most visible on a totally black screen. So enabling the "Reduce DVI frequency" option causes screen blanking in and out (very disturbing), and enabling "Alternate DVI operational mode" causes small artifacts (almost unnoticeable).

== Single-link DVI ==

No thinkpads are currently capable of supporting dual-link DVI natively.

Single link is limited to 165MHz, while dual link has double that.

1600x1200x60=115200000Hz or 115.2MHz (assuming no blanking space), so in theory that should not be a problem, but in practice there might be additional limitations, such as the quality of the video controller and the passthrough to the dock or port replicator.

The IBM video drivers have always limited DVI output to 1280x1024, probably due to these issues.
Some people have had success hacking the drivers (or using alternative drivers), and going up to 1920x1200, but other people get corruption already at 1600x1200.

1920x1200x60=138240000Hz or 138.24MHz

== X40? ==
The article says the X40 is affected by this issue---how is that? Are there any X40 docs or adapters that give the X40 DVI capability at all?
----
The X4x and X6x series use Intel GMA Integrated Video without any DVI support. (that's the same problem with T4x with Intel Video). To get DVI support, you could try using Matrox DualHead2Go or TripleHead2Go to convert your single VGA output to two or three DVI outputs. Alternatively, you could get a Dock II and place a PCI DVI video card and use that, or you could use Villagetronic's Cardbus video card and use the DVI ouput.

Just because a ThinkPad is compatible with a Dock or Port Replicator that has a DVI port, does not mean you can actually use it.

== Latest IBM Drivers Don't Support 1600x1200 on all models ==

The latest ThinkPad video driver, 2005 Aug 11 release, version 8.133.2-050525a-024243C-IBM, does *not* appear
to support 1600x1200 mode on a T41 (not T41p) out of the box when using the MiniDock and an NEC 2080UX display.
The Display Properties->Setting tab allows 1600x1200 pixels to be selected, but the display is driven
at 1280x1024. Patched Catalyst drivers from ATI have been working just fine on the T41 for 1600x1200 with only a
few DVI driver issues (flying green pixels) on applications like Celestia.

As I have tested several T4Xp models, it seems that after T41p (like model 2373-GHG) the DVI throughput problem has been solved by IBM using latest drivers (video and presentation director) running Windows XP, however, my users have reported "flickering" on screens randomly (like Dell 20" and 24") and that seems to be solved by using better cables. Don't expect to be able to extend or use very long cables! ((Someone correct me if I'm wrong, but the T40p model has been making trouble for me.))

I have a t41 (Type 2373) non "P" and the Port Replicator II (74p6734)

With the ATI hydra drivers I can drive an Apple 23 inch at 1920x1200 but I cannot set it as the "primary Monitor" which I want to do. I keep the thinkpad and dock in my desk and do not want to even extend onto the notebook LCD.

Any ideas why cannot change the external display to be the "primary" monitor.

FYI -- if I use my Village Tronic PCMCIA video card I can drive monitor as the primary display. However, the video performance of the Village tronic card is very limited and thus my desire to move to the port deplicator DVI connector.

Any ideas ???

Talk:Problem with DVI throughput

2008-06-17T12:29:13Z

Maccess: Added my own experience with the T43 and a note on the X22.

Here's some information I found:

Most DVI devices today use single-link DVI which supports a maximum bandwidth of 165 MHz [http://www.ddwg.org/dvi.html]. I suppose that ThinkPads provide a single-link DVI signal.

To calculate the bandwidth of your signal, in theory you just need to multiply the resolution with the vertical frequency. For example: 1600x1200 @ 85 Hz => 1600*1200*85 Hz = 163 MHz. This looks good, but it is outside the specs - because you need to take into account some extra time. CRTs need a so-called ''blanking time'' between the data for two display lines. This time is needed for something similar to a carriage return on a typewriter: The electron beam needs to be returned to the start of the next line. Additionally, some extra time is needed to transmit information about the border area around the real picture. About 25% of the bandwidth is used for these additional data. [http://graphics.tomshardware.com/graphic/20041129/tft_connection-04.html]

This means, that there is no specific ThinkPad problem with the throughput - you are just trying to transfer video data at a rate that is outside the specs of DVI. Maybe the DVI transmitter inside the ThinkPad even works at this data rate. But the DVI receiver inside the monitor might be "overclocked".

Ordering Recovery CDs

2008-05-15T14:05:37Z

Maccess:

Information on getting Recovery CDs from IBM.

The information on this page is unofficial. It is gathered from personal experiences. It is here to raise your chances of success when you give it a try yourself.

==About Recovery CDs==
Recovery CDs enable you to reproduce the original software state on your ThinkPad. Until the beginning of 2001 IBM delivered recovery CDs with the ThinkPads, but starting with the A30/T23/X22 models ThinkPads have a [[Predesktop Area]], which's purpose is to make Recovery CDs obsolete. However, this is flawed logic, since you will lose both the installed OS AND the [[Predesktop Area]] upon failure of the hard drive. Also, if you buy a drive upgrade the [[Predesktop Area]] will not be on the new drive. Furthermore, spyware and viruses are lately being designed to infiltrate recovery partitions, so if you restore the system from such, you will restore the invading malware along with it. For the time being, Recovery CDs are available on request.

Recovery CDs are localized, meaning that there are specific versions for each language. The language you will get depends on the language of the OS that was shipped with your ThinkPad. There's usually no way to get CDs in a different language from IBM.

==How to get them==

===Creating Recovery CDs from the preinstalled O/S===
In some ThinkPads IBM supplies a utility to create the recovery CDs. You'll find a utility called "Create Recovery Discs" in the "ACCESS IBM" folder of the Start Menu. To create the Recovery discs, you'll need a CD/DVD writer and blank media. The Product Recovery discs set consist of one Rescue and Recovery disc (size of 1 CD-R) and one or more Product recovery discs (size of 1 DVD-R).

Others might want to read the appendix "Creating an image of the hard drive" in this [ftp://ftp.software.ibm.com/pc/pccbbs/access_ibm_en/hpa_aibm.pdf document] from IBM for instructions. It is also usefull when replacing the hard disk. If your Thinkpad does not have a floppy drive, you could try to create a FAT partition on the harddisk and copy the files "fwbackup.exe" and "fwrestor.exe" there.

===From IBM===
Should you fail to create a set of recovery discs before your harddrive fails, you may try to contact IBM service and request for a set.
This can be done by eMail or phone.
[http://www.ibm.com/planetwide/ Support phone numbers]
Site has moved with the Change to Lenovo to [http://www-307.ibm.com/pc/support/site.wss/document.do?sitestyle=lenovo&lndocid=MIGR-4M7HWZ]. Select there Purchase Recovery CD's. Then Select ThinkPad or Lenovo Notebook. You get the phone number list.

are available online.
They are officially called ''Recovery CD service parts.''
If you actually get them, or not, seems to be more a personal decision of the service person dealing with you than following fixed rules. Also it seems to depend on your country (see below).

They will usually expect you to tell them a good reason for your request (see below).
As with every service request, you'll also have to provide your model and serial number to verify the warranty state.
The warranty for your ThinkPad is usually quite long though (3 years in my case), and you can
[http://www-307.ibm.com/pc/support/site.wss/ check online] if your warranty is still in force.
The model number is also used to determine which CDs you will get.

Orders placed during the first month after purchase have proven to be the most successful. Note some people needed to pay a $45.00 fee, plus shipping and tax, for the CDs, regardless of when ordering them. Again, this seems to depend on the mood of the service rep that handles your case.

Note that Recovery CDs are only available for Windows XP Professional for the X24, as per the Customer Service Center in Atlanta, GA. All other operating systems (Windows 2000, 98SE, OS/2, etc...) are no longer available. XP Home was apparently never available for the X24.

====Good reasons to tell====
*You replaced (or will be replacing) your hard drive.
*You upgraded to Vista and now the 'Create Recovery Media' software only offers to make 'Rescue Media', not 'Recovery Discs'. The [http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=VSTA-LENOVO#hp official guide] does not make it clear to create Recovery Discs before upgrading/installing.
*You installed Linux or some other OS and accidentally removed/destroyed the [[Predesktop Area]]. However, support may argue that installing an OS that corrupted the MBR is outside of the warranty, and thus the $45 surcharge still applies. Chances of receiving free recovery discs may be better by providing reasons other than this one.
*You bought a machine in one country (e.g Germany) and need to convert the OS to use a different language (e.g. English).** this is a very bad reason to use, IBM will (or should) tell you that the machine is only supported with the language it is delivered, this is a license requirement between Microsoft / IBM.
*Your computer was unable to run Windows XP and is temporarily running on Windows 2000 (or other O/S)
**in Europe IBM have to provide recovery means due to EU consumer laws but willfull damage are not covered by warranty as per IBMs Terms and Condition of warranty now whether installing linux and thus deleting / formatting the hard drive is "willfull damage" is open to the service reps interpretation so there is possibility of slightly variation here therefore the best way to recieve recovery CDs is to claim no knowledge of the recovery process "pressing the (access IBM / Lenovo care) button but nothing happens it will not start windows can you send me some CDs so i can reinstall?" this will near always work.

====What happens then====
The time of delivery varies. In some cases its very fast (times from 16h to 3 days have been reported), on the other hand it has been reported that the time of delivery is very high, three weeks for example. The shipping can happen without prior confirmation of your request, so don't be worried if you hear nothing within this time.

A IBM/Lenovo customer requested a Z60M recovery disc set at 1:00pm Thursday afternoon with Atlanta,Ga Tech Center and shipped from Morrisville,NC with Airborne Express and hand delived to Valparaiso,IN address Monday morning 9:00am,that's was fast! and it was on a weekend. Also the IBM/Lenovo Rep give a software order number and a telephone number to call,if the package doesn't arrived in three business days.The package has 1 R&R Startup CD,1 R&R Supplemental CD and 6 Recovery CD. and IBM/Lenovo is picking up the cost.

A Dutch IBM customer reported next-day delivery of recovery CDs, on three different occasions. A customer in Belgium had to wait 8 days, so sometimes delivery is not that fast.

Apparently recovery CDs to the UK are now shipped from Hungary, with an estimated delivery of 8-9 days. Experience shows they tend to come a little sooner. It seems likely that this is now the source for all of Europe.

Ordering Recovery CDs

2008-05-15T14:02:17Z

Maccess: detail on Philippines

Information on getting Recovery CDs from IBM.

The information on this page is unofficial. It is gathered from personal experiences. It is here to raise your chances of success when you give it a try yourself.

==About Recovery CDs==
Recovery CDs enable you to reproduce the original software state on your ThinkPad. Until the beginning of 2001 IBM delivered recovery CDs with the ThinkPads, but starting with the A30/T23/X22 models ThinkPads have a [[Predesktop Area]], which's purpose is to make Recovery CDs obsolete. However, this is flawed logic, since you will lose both the installed OS AND the [[Predesktop Area]] upon failure of the hard drive. Also, if you buy a drive upgrade the [[Predesktop Area]] will not be on the new drive. Furthermore, spyware and viruses are lately being designed to infiltrate recovery partitions, so if you restore the system from such, you will restore the invading malware along with it. For the time being, Recovery CDs are available on request.

Recovery CDs are localized, meaning that there are specific versions for each language. The language you will get depends on the language of the OS that was shipped with your ThinkPad. There's usually no way to get CDs in a different language from IBM.

==How to get them==

===Creating Recovery CDs from the preinstalled O/S===
In some ThinkPads IBM supplies a utility to create the recovery CDs. You'll find a utility called "Create Recovery Discs" in the "ACCESS IBM" folder of the Start Menu. To create the Recovery discs, you'll need a CD/DVD writer and blank media. The Product Recovery discs set consist of one Rescue and Recovery disc (size of 1 CD-R) and one or more Product recovery discs (size of 1 DVD-R).

Others might want to read the appendix "Creating an image of the hard drive" in this [ftp://ftp.software.ibm.com/pc/pccbbs/access_ibm_en/hpa_aibm.pdf document] from IBM for instructions. It is also usefull when replacing the hard disk. If your Thinkpad does not have a floppy drive, you could try to create a FAT partition on the harddisk and copy the files "fwbackup.exe" and "fwrestor.exe" there.

===From IBM===
Should you fail to create a set of recovery discs before your harddrive fails, you may try to contact IBM service and request for a set.
This can be done by eMail or phone.
[http://www.ibm.com/planetwide/ Support phone numbers]
Site has moved with the Change to Lenovo to [http://www-307.ibm.com/pc/support/site.wss/document.do?sitestyle=lenovo&lndocid=MIGR-4M7HWZ]. Select there Purchase Recovery CD's. Then Select ThinkPad or Lenovo Notebook. You get the phone number list.

are available online.
They are officially called ''Recovery CD service parts.''
If you actually get them, or not, seems to be more a personal decision of the service person dealing with you than following fixed rules. Also it seems to depend on your country (see below).

They will usually expect you to tell them a good reason for your request (see below).
As with every service request, you'll also have to provide your model and serial number to verify the warranty state.

Talk:ThinkPad Mini-Dock

2008-05-11T14:35:07Z

Maccess:

Hi,

recently I compared the specs of the three "docking stations" that fit my R50p.

The Mini Dock's power supply is '''not''' integrated into the case, you need a proprietary '''external''' power supply that you cannot connect to the laptop directly. It has 120W compared to the standard power supply's 70W.

[http://www-307.ibm.com/pc/support/site.wss/MIGR-45932.html]

I think this is a big disadvantage over the Port Replicator II. According to the IBM specs, the Mini Dock is about 10% heavier (presumably the device only, the power supply itself should be heavier too), and it's only advantages are the USB hub and the key lock.

For me the Port Replicator II seems to be the better choice: Less expensive, lighter and no need to care about a second different(!) power supply.

The ThinkPad Dock II is a completely different league, it's a complex and heavy system extension.

Unfortunately, I didn't have one of these things in my hands yet. So can anybody here tell us about his/her real live experiences?

thanks

Steve

:I have several Port Replicator IIs, and saw an ad for the Mini Dock. Like yourself, the only real difference I saw was the built-in USB port.

The PRII locks the Thinkpad when a Kensington lock is connected--the unlatch key can't be depressed, so the MDII's lock isn't really an advantage (unless you consider being able to unlock the Thinkpad separately from the dock's Kensignton lock an andvantage).

The MD would have something going for it if the USB hub is powered. I don't know for sure, since I can't find a site that will tell me either way.

My Port Replicator is connected to a hub that is powered through an APC universal laptop charger that has a USB power port. The APC also has the advantage of being able to run off 12Volts, which is occasionally useful in the third world. However, if the MD has a powered hub, i might consider it--but only if I can get it used for the same price as the PRII+cost of USB hub+Thinkpad adaptor. The MDs biggest disadvantage is its price premium. [[User:Maccess|Maccess]] 16:35, 11 May 2008 (CEST)

ThinkPad Port Replicator II

== IBM ThinkPad Port Replicator II ==
The [[ThinkPad Port Replicator II|Port Replicator II]] (Model # 74P6733) is the cheapest dock IBM sells. It contains basic pass-through connections for notebook ports, including power pass-through. It comes without integrated power supply but provides the same power jack as found in a ThinkPad, so you need to use either your Thinkpad AC adapter or another IBM AC adapter. Besides all the pass-through ports the Port Replicator II comes with an On/Off switch and a slot for a cable lock which secures the device and prevents the Thinkpad from being removed.

===Features===
* Passthrough ports:
** Ethernet (RJ45)
** Modem (RJ11)
** USB (1-port)
** DVI
** [[VGA Port|VGA]]
** [[Serial Port|Serial (DB9-M)]]
** [[Parallel Port|Parallel (DB25-F)]]
** [[PS/2 Port|PS/2 Keyboard]]
** [[PS/2 Port|PS/2 Mouse]]
** [[Floppy Connector|External Diskette drive]]
** Audio line-in and line-out
* Kensington Lock connector
* Power button

===Properties===
* Price: Inexpensive ($149 Retail, under $30 on eBay)
* Uses the same type of AC adapter as the laptop itself.
* AC adapter required only for charging (since the connectors are simple pass-through)
* On models where the DVI port is functional (ATI Video Chipset), the DVI and Dock VGA ports may be used to drive dual monitors. In WindowsXP, download and install the latest Catalyst driver and Driver Heaven Mod Kit. When both VGA and DVI ports are used, the laptop's built-in monitor is disabled.
* Only one USB port.
* The line-out output is just that. Unlike the ThinkPad's built-in stereo output, it does '''not''' have sufficient power to directly drive headphones, and will clip and distort horribly if you try doing so.
* Compatibility: X20/30, T20/30/40, R30/40/50, and A20/30 series (Does not support X40/41, R40e/50e/51e, or G40/41)
* Warranty: One Year

==DVI pass-through==
LCD monitors are getting larger and higher-resolution. Currently, DVI based on 165MHz TDMS transmitters can only (officially) support 1600x1200x32 at 60Hz, which is the resolution of your average 20" non-widescreen LCD. IBM's driver support for this resolution through DVI ports on docks has been inconsistent. Also in Linux you might experience [[Problem with DVI throughput|problems]] even with this resolution and IBM officially states that the pass-through DVI port only supports resolutions up to 1280x1024. Read [[Problem with DVI throughput|our page]] of information on how to solve these troubles.

Please be aware that not all Thinkpad models will support DVI output with a Port Replicator. This is stated as "If your ThinkPad computer does not support DVI, you cannot use this connector." in User's guide. Apparently, X and T2* models do not. [http://www-307.ibm.com/pc/support/site.wss/document.do?sitestyle=lenovo&lndocid=MIGR-58833#vid ThinkPad R52] and [http://www-307.ibm.com/pc/support/site.wss/document.do?sitestyle=lenovo&lndocid=MIGR-58317#vid ThinkPad T43] models with Intel Graphics Media Accelerator do not. Please add other models if you know about them to not support DVI.

== Supported ThinkPads ==
* ThinkPad {{A20m}}, {{A20p}}, {{A21m}}, {{A21p}}, {{A22e}}, {{A22m}}, {{A22p}}

Talk:ThinkPad Port Replicator II

2008-05-09T02:53:01Z

Maccess: DVI support ATI

I have this Port replicator and was wondering if the '''DVI''' port is incompatable with my system.
I have Thinkpad R40 2722-BBG.
Thanks,
----
There is almost no documentation on which systems support DVI, and which do not.

If I where to guess, I would say no, but the best way to find out is to simply attach a DVI display and see if it works.

If you find out, either way, let us know.

--[[User:Tonko|Tonko]] 02:44, 2 Nov 2005 (CET)

Generally speaking. Thinkpads which use Intel Integrated graphics don't support DVI ports. Those with ATI graphics support the DVI, and most ATI grpahics support simultaneous use of the DVI and VGA ports for dual external monitors. In this mode, the built-in LCD is turned off as the chip can only drive two monitors). [[User:Maccess|Maccess]] 04:53, 9 May 2008 (CEST)
----
Does anybody know anything about the compatibility to '''Linux''' in general? Does anything work without problems?

Is it really compatible with the '''R52''' (1860), it's not listed on the IBM/Lenovo website [[http://www-131.ibm.com/webapp/wcs/stores/servlet/ProductDisplay?catalogId=-840&storeId=10000001&langId=-1&dualCurrId=73&categoryId=2581897&productId=8581830]].

Thank you

--[[User:Kwbolte|Kwbolte]] 17:28, 26 Dec 2005 (CET)

No problem whatsoever with '''T41''' and this replicator in '''Linux'''. I have most of the ports in use, except DVI.

--[[User:APz|APz]] 03:29, 28 January 2008 (CET)

== Limitations of video signal output ==

Apparently, some thinkpad port replicators II and some thinkpads don't play well with the video signal when connected.

This is '''not''' a general problem of all thinkpads and all port replicators, so I have removed the only report so far to the talk page. Please update the topic, and when we get some sort of idea of what is affected by what, we can update the main page.

--[[User:Hmh|hmh]] 04:11, 12 July 2007 (UTC)

Screen resolution restricted to 640x480 when attached to the port replicator. Without, 1024x768 (on a T40 2373-12G) possible.

#While the physical disk is PATA (IDE), it is accessed through a SATA controller and a SATA-to-PATA bridge. It thus appears as a SATA device to the operating system, which causes some [[Problems with SATA and Linux|problems under Linux]]. The SATA-to-PATA bridge also necessitates drive firmware changes, causing a [[Problem with non-ThinkPad hard disks|problem with non-ThinkPad hard disks]].

== IBM ThinkPad Port Replicator II ==
The [[ThinkPad Port Replicator II|Port Replicator II]] (Model # 74P6733) is the cheapest dock IBM sells. It contains basic pass-through connections for notebook ports, including power pass-through. It comes without integrated power supply but provides the same power jack as found in a ThinkPad, so you need to use either your Thinkpad AC adapter or another IBM AC adapter. Besides all the pass-through ports the Port Replicator II comes with an On/Off switch and a slot for a cable lock which secures the device and prevents the Thinkpad from being removed.

===Features===
* Passthrough ports:
** Ethernet (RJ45)
** Modem (RJ11)
** USB (1-port)
** DVI
** [[VGA Port|VGA]]
** [[Serial Port|Serial (DB9-M)]]
** [[Parallel Port|Parallel (DB25-F)]]
** [[PS/2 Port|PS/2 Keyboard]]
** [[PS/2 Port|PS/2 Mouse]]
** [[Floppy Connector|External Diskette drive]]
** Audio line-in and line-out
* Kensington Lock connector
* Power button

===Properties===
* Price: Inexpensive ($149 Retail, under $30 on eBay)
* Uses the same type of AC adapter as the laptop itself.
* AC adapter required only for charging (since the connectors are simple pass-through)
* On models where the DVI port is functional (ATI Video Chipset), both the DVI and VGA ports may be used in a dual monitor set-up. In WindowsXP, download and install the latest Catalyst driver and Driver Heaven Mod Kit. When both VGA and DVI ports are used, the laptop's built-in monitor is disabled.
* Only one USB port
* The line-out output is just that. Unlike the ThinkPad's built-in stereo output, it does '''not''' have sufficient power to directly drive headphones, and will clip and distort horribly if you try doing so.
* Compatibility: X20/30, T20/30/40, R30/40/50, and A20/30 series (Does not support X40/41, R40e/50e/51e, or G40/41)
* Warranty: One Year

==DVI pass-through==
LCD monitors are getting larger and higher-resolution. Currently, DVI based on 165MHz TDMS transmitters can only (officially) support 1600x1200x32 at 60Hz, which is the resolution of your average 20" non-widescreen LCD. IBM's driver support for this resolution through DVI ports on docks has been inconsistent. Also in Linux you might experience [[Problem with DVI throughput|problems]] even with this resolution and IBM officially states that the pass-through DVI port only supports resolutions up to 1280x1024. Read [[Problem with DVI throughput|our page]] of information on how to solve these troubles.

Please be aware that not all Thinkpad models will support DVI output with a Port Replicator. This is stated as "If your ThinkPad computer does not support DVI, you cannot use this connector." in User's guide. Apparently, X and T2* models do not. [http://www-307.ibm.com/pc/support/site.wss/document.do?sitestyle=lenovo&lndocid=MIGR-58833#vid ThinkPad R52] and [http://www-307.ibm.com/pc/support/site.wss/document.do?sitestyle=lenovo&lndocid=MIGR-58317#vid ThinkPad T43] models with Intel Graphics Media Accelerator do not. Please add other models if you know about them to not support DVI.
