<div>This page provides information about pixel and subpixel errors.<br />
<br />
==What are dead pixels or dead subpixels?==<br />
Dead Pixels are a phenomenon caused by the technology of LCD displays. TFT displays consist of a huge number of individual display cells, each controlled by its own transistor. I.E. a display with a resolution of 1024x768 pixels consists of 1024x768x3 = 2,36 million cells. A such enormous number makes the production of a display without any faulty cell difficult. The more strict the quality restrictions are, the more expensive the panels get, because this simply means raising the number of garbage panels.<br />
<br />
==Types of pixel errors==<br />
Here is a listing of possible types of dead pixels / subpixels:<br />
{| cellspacing=0 cellpadding=2 border=1 style="text-align:center"<br />
! pixel type<hr />state type !! pixel !! red subpixel !! green subpixel !! blue subpixel<br />
|-<br />
| always lit || <span style="width:15px;height:15px;border:1px solid black;background-color:black;color:white;">&nbsp;&nbsp;&#183;&nbsp;&nbsp;</span> || <span style="width:15px;height:15px;border:1px solid black;background-color:black;color:#ff0000;">&nbsp;&nbsp;&#183;&nbsp;&nbsp;</span> || <span style="width:15px;height:15px;border:1px solid black;background-color:black;color:#00ff00;">&nbsp;&nbsp;&#183;&nbsp;&nbsp;</span> || <span style="width:15px;height:15px;border:1px solid black;background-color:black;color:#0000ff;">&nbsp;&nbsp;&#183;&nbsp;&nbsp;</span><br />
|-<br />
| always unlit || <span style="width:15px;height:15px;border:1px solid black;background-color:white;color:#000000;">&nbsp;&nbsp;&#183;&nbsp;&nbsp;</span> || <span style="width:15px;height:15px;border:1px solid black;background-color:white;color:#00ffff;">&nbsp;&nbsp;&#183;&nbsp;&nbsp;</span>&nbsp;<span style="width:15px;height:15px;border:1px solid black;background-color:#ff0000;color:#000000;">&nbsp;&nbsp;&#183;&nbsp;&nbsp;</span> || <span style="width:15px;height:15px;border:1px solid black;background-color:white;color:#ff00ff;">&nbsp;&nbsp;&#183;&nbsp;&nbsp;</span>&nbsp;<span style="width:15px;height:15px;border:1px solid black;background-color:#00ff00;color:#000000;">&nbsp;&nbsp;&#183;&nbsp;&nbsp;</span> || <span style="width:15px;height:15px;border:1px solid black;background-color:white;color:#ffff00;">&nbsp;&nbsp;&#183;&nbsp;&nbsp;</span>&nbsp;<span style="width:15px;height:15px;border:1px solid black;background-color:#0000ff;color:#000000;">&nbsp;&nbsp;&#183;&nbsp;&nbsp;</span><br />
|}<br />
<br />
You can notice here, that always lit complete pixels, red subpixels and green subpixels are the most annoying ones. Also, dead pixels located closer to the center of the screen are more annoying than such located closer to the edge of the screen.<br />
<br />
Dead pixels do not always have to be a constant phenomena. You might in fact experience your pixel in question be faulty at times and working perfectly at other times. Or you might experience it to be a little flickering. This is only logical since a faulty transistor might sometimes work and sometimes not, depending on environmental conditions or even just randomly.<br />
<br />
{{HINT|The table above also shows you a way of detecting dead pixels and subpixels. Just use plain colored screens.}}<br />
<br />
<br />
==The ISO 13406-2 norm==<br />
However, to give the concerned customer more transparency when bying LCD displays, the ISO norm 13406-2 was introduced, providing a basis for warranty claims. By assuring one of the classes of this specification, the producer is bound to keep that quality standard throughout the whole production series. However, Manufacturers are not necessarily going with this standard. For values for IBM displays look at [http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-4U9P53 this page].<br />
<br />
The values in the following table state the acceptable errors per 1 million pixels. Dead pixels form a cluster when they are within a square of 5x5 pixels.<br />
<br />
{| cellspacing=0 cellpadding=2 border=1 style="text-align:center"<br />
! Error class !! Type 1<br />(always lit pixel) !! Type 2<br />(always unlit pixel) !! Type 3<br />(always lit or always unlit subpixel) !! Type 4<br />(clusters with more than one Type 1 or Type 3 faults) !! Type 4<br /> (clusters of Type 3 faults)<br />
|-<br />
| I || 0 || 0 || 0 || 0 || 0<br />
|-<br />
| II || 2 || 2 || 5 || 0 || 2<br />
|-<br />
| III || 5 || 15 || 50 || 0 || 5<br />
|-<br />
| IV || 50 || 150 || 500 || 5 || 50<br />
|}<br />
<br />
<br />
==Causes for dead pixels/subpixels==<br />
* As stated above, dead pixels are an inherent feature of the technology/production process of TFT displays. How many of them are in the final displays sold is just a mater of quality control standards.<br />
* Furthermore, they can also accur at random time after production. Transistors can have faults that are not recognizable at production time. These faults may make the transistor stop working after it has been in use for a certain amount of time.<br />
* Mechanical or environmental stress (i.e. heat) can possibly damage a transistor, leading to pixel errors.<br />
<br />
<br />
==Don't panic!==<br />
Dead pixels are a really common phenomena on TFT displays. In fact there are other things about TFT displays that matter a lot more, like brightness and contrast, picture stability, color reproduction and response time. People just tend to focus on those things that are the most obvious, that's why everyone cries for dead pixels and response time when it comes to TFT displays.<br />
<br />
However, as stated above there can be truely annoying types of dead pixels. If their count is higher than the displays quality class permits you might get the device replaced under warranty.<br />
The best thing, however, is to look for dead pixels right after purchase (you might have a chance to return it without special reason then):<br />
* Do it three times over two days - different moods and different environemental light have an influence on your perception.<br />
* [http://freshmeat.net/projects/lcdtest lcdtest] utility can generate predefined patterns, and may help you to detect damaged pixels.<br />
* Be concious about how hard it was to find the dead pixel - if it was really hard it can't be too bothering.<br />
* Also make sure that what you consider a dead pixel isn't just a piece of dirt or dust.<br />
<br />
==Solutions==<br />
Besides some april jokes there isn't really any solution except looking for a replacement.<br />
<br />
However, for {{Windows}} an interesting program exists that can help you making annoying subpixels and pixels more bearable. It works by trying to compensate dead a subpixel by adjusting the values for the remaining working subpixels. This way you can i.e. get rid of a most annoying always lit red subpixel. The program is german only and a download link can be found in its german [http://www.prad.de/board/thread.php?threadid=11797 PixChanger discussion].<br />

<div>I am reasonably sure a Floppy drive does not exist for the UltraBay Slim.<br />
People are told to use a USB FDD instead.<br />
<br />
Also the UltraBay 2000 battery is not supported in UltraBay Plus.<br />
UltraBay Plus has its own battery that should be used<br />
<br />
----<br />
<br />
Anyone know if it's possible to bodge together a 770X Ultrabay II CD-RW from a Ultrabay II DVD and, say, a 600E UltraSlimBay CD-RW? Just something I've been wondering for a while.<br />

== UltraBay II? ==<br />
<br />
Does it seem odd that the UltraBay II was the ''first'' bay? Was there no UltraBay, or some other type of bay? -- [[User:Whizkid|Whizkid]] 00:51, 16 Apr 2005 (CEST)<br />
<br />
----<br />
True. ;-) It seems, that actually the drive bay in the 380 models was called UltraBay, but i don't know for sure. So i didn't add it.<br />
<br />

<br />
== Not just IDE ==<br />
<br />
Obviously UltraBay is not just an IDE interface.<br />
<br />
Most also have a floppy interface (apart from the latest 'slim' and 'enhanced' versions), and can take a battery.<br />
<br />
If I remember correctly you could get the floppy drive activated by hibernating the thinkpad and installing the floppy drive, so that on power up the BIOS would enable the floppy disk drive and it would work. This was in the old APM days, so it might work differently with ACPI.<br />
<br />
----<br />
You're right. I remember reading some IBM text about the UltraBay yesterday, which said that the controller is capable of dynamically changing the pin layout to support the different kind of devices (initiated by the BIOS). I'll try finding it again and correcting the information on the page.<br />
<br />
[[User:Wyrfel|Wyrfel]] 23:16, 17 Apr 2005 (CEST)<br />
----<br />
<br />
On my 770x under ACPI, if you force the floppy driver to use 2 3.5" drives (in modprobe.conf options floppy floppy=1,4,cmos), then you get to use either external floppy / ultrabay floppy / both if you plug them in after boot time. Otherwise the autodetect only finds one. I still haven't got hotplug fully working (mostly as it depends on Linux being able to hotplug IDE devices, not just IDE controllers).<br />
<br />
[[User:lentinj|lentinj]]<br />
----<br />
I added a page for the drive ([[UltraBay II Floppy Drive]]) containing your info. [[User:Wyrfel|Wyrfel]] 21:24, 9 Aug 2005 (CEST)<br />
<br />
== First UltraBay ==<br />
The oldest references I can find to the name 'UltraBay' are the ThinkPad 755 series (755CSE, 755CE, etc).<br />
<br />
But the older 750 models already had the hot-swappable drive bay, and support some of the same options, so it looks like the 'UltraBay' started with the 750 series.<br />
<br />
But then again, later models support CD-ROM drives (755CD, 760CD, etc), which certainly are not supported in these older models, but they are all called 'UltraBay'.<br />
<br />
Tonko<br />

<br />
My understanding of the original Ultrabays is as follows:<br><br />
<br />
===UltraBay===<br />
* ThinkPads:<br />
** 355, 355C, 355Cs<br />
** 360, 360C, 360Cs, 360P, 360CE, 360CSE, 360PE<br />
** 370C<br />
** 750, 750C, 750Cs, 750P<br />
** 755C, 755Cs, 755CE, 755CSE, 755CX<br />
** 760C, 760L, 760E (thin model)<br />
* Devices (probably not all devices are supported in every ThinkPad):<br />
** 1.44MB FDD<br />
** 2.88MB FDD<br />
** Cellular Digital Packet Data (CDPD) - not compatible with 360P, 360PE, 750P<br />
** IBM Wireless Modem for ARDIS<br />
** TV Tuner (NTSC)<br />
** 2nd HDD<br />
** 2nd Battery<br />
** PCMCIA Cartridge<br />
<br />
===UltraBay - Thick ===<br />
* ThinkPads:<br />
** 755CD, 755CDV<br />
** 760CD, 760LD, 760EL, 760ELD, 760E (thick model), 760XL, 760XD<br />
** 765D, 765L<br />
* Supports UltraBay devices, in addition to:<br />
** CD-ROM drive<br />

IBM FRU PN: 19K4510<br />
<br />
=== Linux driver ===<br />
The Compact Flash Card Reader is accessable via the USB Mass Storage driver, just like a usual USB memory stick.<br />
<br />
Since the USB Mass Storage driver is SCSI based you'll need SCSI support in your kernel. Enable the following options:<br />
:{{kernelconf|||Device Drivers|SCSI device support|SCSI device support|[M]|CONFIG_SCSI}}<br />
:{{kernelconf|||Device Drivers|SCSI device support|SCSI disk support|[M]|CONFIG_BLK_DEV_SD}}<br />
:{{kernelconf|||Device Drivers|SCSI device support|SCSI generic support|[M]|CONFIG_CHR_DEV_SG}}<br />
<br />
Furthermore, enable USB support:<br />
:{{kernelconf|||Device Drivers|USB support|Support for Host-side USB|<M>|CONFIG_USB}}<br />
:{{kernelconf|||Device Drivers|USB support|USB device file system|[*]|CONFIG_USB_DEVICEFS}}<br />
<br />
Choose an appropriate USB host driver, one of: <br />
:{{kernelconf|||Device Drivers|USB support|ECHI HCD (USB 2.0) support|<M>|CONFIG_USB_EHCI_HCD}}<br />
:{{kernelconf|||Device Drivers|USB support|UHCI HCD support|<M>|CONFIG_USB_UHCI}}<br />
:{{kernelconf|||Device Drivers|USB support|OHCI HCD support|<M>|CONFIG_USB_OHCI}}<br />
<br />
Finally, enable the USB Mass Storage driver:<br />
:{{kernelconf|||Device Drivers|USB support|USB Mass Storage support|<M>|CONFIG_USB_STORAGE}}<br />
<br />
{{NOTE|Make sure that the <tt>Low Performance USB Block Driver (BLK_DEV_UB)</tt> is disabled. It would prevent the whole thing from working correctly.}}<br />
<br />
Compile your kernel with these options (don't forget {{cmdroot|depmod -ae}}) and reboot or just load the relevant modules (<tt>scsi, sd_mod, sg, usb, usb-ehci/usb-uhci/usb-ohci, usb-storage</tt>). If you didn't already, plug in the card reader and insert a CF card.<br />
<br />
Do a {{cmdroot|cat /proc/bus/usb/devices}} to asure yourself that your card reader is recognized by the USB subsystem.<br />
<br />
Now also check if the USB Mass Storage driver is working properly by doing a {{cmdroot|cat /proc/scsi/scsi}}.<br />
<br />
Usually, your card reader will be associated with {{path|/dev/sda}} and hence it's first (and mostly only partition) will be {{path|/dev/sda1}}. You can check that using the [http://sg.torque.net/sg/index.html#Utilities:%20sg_utils%20and%20sg3_utils sg3_utils].<br />
<br />
You may want to put an entry in your {{path|/etc/fstab}}, i.e. with the above assumtions:<br />
/dev/sda1 /media/cf auto noauto,users 0 0<br />
<br />
That's it. Your card reader should be working now.<br />

This is a WebCam for the IBM UltraPort. It can also be connected to any USB port by using the included cable.<br />
<br />
There is virtually no difference between the UltraPort Camera and the UltraPort Camera II. The latter one was in fact released shortly after the first one and the camera module itself is exactly the same. IBM changed the marketing name to distinguish a new packaging, which in addition to the original one included the following:<br />
*a small spacer to allow the camera to be attached to the UltraPort of X series models<br />
*updated software (new build numbers, not new versions), only few minor enhancements<br />
*FaceIt face recognition screensaver<br />
That's it, nothing more to it.<br />

=== IBM UltraPort Infrared Adapter ===<br />
This is a Infrared Adapter for the IBM UltraPort. It can also be connected to any USB port by using the included cable.<br />
<br />
This adapter is especially useful for {{X20}} and {{X21}} ThinkPads, since they are not equipped with IrDA ports by default.<br />
<br />
=== Features ===<br />
* Front to back swivel for greater infrared field of view<br />
* Transfer rate up to 4 Mbps<br />
* Maximum range up to 1 meter (3 feet)<br />
* UltraPort and USB interfaces<br />

<br />
=== Linux driver ===<br />
This adapter works with the irda-usb driver of 2.6 type kernels. To enable it, follow these steps:<br />
<br />
Enable USB support:<br />
:{{kernelconf|||Device Drivers|USB support|Support for Host-side USB|<M>|CONFIG_USB}}<br />
:{{kernelconf|||Device Drivers|USB support|USB device file system|[*]|CONFIG_USB_DEVICEFS}}<br />
<br />
Choose an appropriate USB host driver, one of: <br />
:{{kernelconf|||Device Drivers|USB support|ECHI HCD (USB 2.0) support|<M>|CONFIG_USB_EHCI_HCD}}<br />
:{{kernelconf|||Device Drivers|USB support|UHCI HCD support|<M>|CONFIG_USB_UHCI}}<br />
:{{kernelconf|||Device Drivers|USB support|OHCI HCD support|<M>|CONFIG_USB_OHCI}}<br />
<br />
Enable IrDA support:<br />
:{{kernelconf|||Device Drivers|Networking support|IrDA (infrared) subsystem support|<M>|CONFIG_IRDA}}<br />
:{{kernelconf||Device Drivers|Networking support|IrDA (infrared) subsystem support|IrLAN protocol|<M>|CONFIG_IRLAN}}<br />
:{{kernelconf||Device Drivers|Networking support|IrDA (infrared) subsystem support|IrNET protocol|<M>|CONFIG_IRNET}}<br />
:{{kernelconf||Device Drivers|Networking support|IrDA (infrared) subsystem support|IrCOMM protocol|<M>|CONFIG_IRCOMM}}<br />
<br />
Finally, enable the irda-usb driver:<br />
:{{kernelconf|Device Drivers|Networking support|IrDA (infrared) subsystem support|Infrared-port device drivers|IrDA USB dongles|<M>|CONFIG_USB_IRDA}}<br />
<br />
Compile your kernel with these options (don't forget {{cmdroot|depmod -ae}}) and reboot or just load the relevant modules (<tt>usb, usb-ehci/usb-uhci/usb-ohci, usb-storage, irda, irlan, irnet, ircomm, ircomm_tty, irda-usb</tt>). Attach the IrDA adapter to the UltraPort, if not done already.<br />
<br />
Do a {{cmdroot|cat /proc/bus/usb/devices}} to asure yourself that your IrDA adapter is recognized by the USB subsystem.<br />

<hr />
<div>I am reasonably sure a Floppy drive does not exist for the UltraBay Slim.<br />
People are told to use a USB FDD instead.<br />
<br />
Also the UltraBay 2000 battery is not supported in UltraBay Plus.<br />
UltraBay Plus has its own battery that should be used<br />
<br />
----<br />
<br />
Anyone know if it's possible to bodge together a 770X Ultrabay II CD-RW from a Ultrabay II DVD and, say, a 600E UltraSlimBay CD-RW? Just something I've been wondering for a while.<br />
<br />

== UltraBay II? ==<br />
<br />
Does it seem odd that the UltraBay II was the ''first'' bay? Was there no UltraBay, or some other type of bay? -- [[User:Whizkid|Whizkid]] 00:51, 16 Apr 2005 (CEST)<br />
<br />
----<br />
True. ;-) It seems, that actually the drive bay in the 380 models was called UltraBay, but i don't know for sure. So i didn't add it.<br />
<br />
[[User:Wyrfel|Wyrfel]] 00:36, 17 Apr 2005 (CEST)<br />

<br />
== Not just IDE ==<br />
<br />
Obviously UltraBay is not just an IDE interface.<br />
<br />
Most also have a floppy interface (apart from the latest 'slim' and 'enhanced' versions), and can take a battery.<br />
<br />
If I remember correctly you could get the floppy drive activated by hibernating the thinkpad and installing the floppy drive, so that on power up the BIOS would enable the floppy disk drive and it would work. This was in the old APM days, so it might work differently with ACPI.<br />
<br />
----<br />
You're right. I remember reading some IBM text about the UltraBay yesterday, which said that the controller is capable of dynamically changing the pin layout to support the different kind of devices (initiated by the BIOS). I'll try finding it again and correcting the information on the page.<br />
<br />
[[User:Wyrfel|Wyrfel]] 23:16, 17 Apr 2005 (CEST)<br />

<br />
== First UltraBay ==<br />
The oldest references I can find to the name 'UltraBay' are the ThinkPad 755 series (755CSE, 755CE, etc).<br />
<br />
But the older 750 models already had the hot-swappable drive bay, and support some of the same options, so it looks like the 'UltraBay' started with the 750 series.<br />
<br />
But then again, later models support CD-ROM drives (755CD, 760CD, etc), which certainly are not supported in these older models, but they are all called 'UltraBay'.<br />
<br />
Tonko<br />
----<br />
<br />
My understanding of the original Ultrabays is as follows:<br><br />
<br />
===UltraBay===<br />
* ThinkPads:<br />
** 355, 355C, 355Cs<br />
** 360, 360C, 360Cs, 360P, 360CE, 360CSE, 360PE<br />
** 370C<br />
** 750, 750C, 750Cs, 750P<br />
** 755C, 755Cs, 755CE, 755CSE, 755CX<br />
** 760C, 760L, 760E (thin model)<br />
* Devices (probably not all devices are supported in every ThinkPad):<br />
** 1.44MB FDD<br />
** 2.88MB FDD<br />
** Cellular Digital Packet Data (CDPD) - not compatible with 360P, 360PE, 750P<br />
** IBM Wireless Modem for ARDIS<br />
** TV Tuner (NTSC)<br />
** 2nd HDD<br />
** 2nd Battery<br />
** PCMCIA Cartridge<br />
<br />
===UltraBay - Thick ===<br />
* ThinkPads:<br />
** 755CD, 755CDV<br />
** 760CD, 760LD, 760EL, 760ELD, 760E (thick model), 760XL, 760XD<br />
** 765D, 765L<br />
* Supports UltraBay devices, in addition to:<br />
** CD-ROM drive<br />

== Optical drive adapters ==<br />
I can´t include this information easily in ThinkWiki. Please, help me!<br />
<br />
<br />
I think adapters P/N (or FRU P/N) should also be mentioned: above webpages can disappear in a future, and the P/N is an unequivocal reference!. Adapters may work only in selected models!!<br />
<br />
<br />
<br />
<br />
'''Ultrabay Enhanced optical drive Adapter''' (P/N 73P3268 ¿or 73P3269?): it allows to use an Ultrabay Enhanced optical-drive inside of an Ultrabay 2000/Ultrabay Plus bay. Only supported in a limited list of models?.<br />

<hr />
<div>IBM has reported in March 2005 that some 56W adapters manufactured by Delta Electronics Inc. may suffer overheat, resulting in melting of adapter housing and charring of the circuit board inside the housing.<br />
<br />
<br />
<br />
Only one AC-adapter part number is affected: '''P/N 02K6549''' ([http://www-307.ibm.com/pc/support/site.wss/56587_56w_ac_adapter.jpg See photograph here]). No other IBM ThinkPad AC adapters are affected.<br />
<br />
<br />
<br />
<br />
Laptops that ''originally'' carry this AC-adapter are:<br />
* ThinkPad i Series 1200/1300 (Machine Types 1161, 1171, 2666, 2667)<br />
* ThinkPad i Series 1400/1500 (Machine Types 2621, 2651)<br />
* ThinkPad i Series 1700 (Machine Type 2627)<br />
* ThinkPad 240 (Machine Type 2609, 2612)<br />
* ThinkPad 390 (Machine Types 2624, 2626)<br />
* ThinkPad s Series (Machine Types 2638, 2639).<br />
(but you ''may'' be also using this 56W adapter with other ThinkPad models!!).<br />
<br />
<br />
<br />
If your AC adapter is P/N 02K6549, IBM will replace the AC adapter, free of charge; just follow this link: [http://www.adapterprogram.com/ibac/ IBM AC Adapter Replacement Program].<br />
