ThinkPad X200

+

+ This sections relates to known hardware compatibility in libreboot. +

+

+ Or back to main index. +

+ +

+ It is believed that all X200 laptops are compatible. X200s and X200t may also work, + but require soldering (for the initial installation/flashing of a ROM image, or + dumping the current firmware). Only the X200 is tested so far. +

+

+ It *might* be possible to put an X200 motherboard in an X201 chassis, though this is currently untested + by the libreboot project. The same may also apply between X200s and X201s; again, this is untested. + It's most likely true. +

+ +

+ There are two possible flash chip sizes for the X200: 4MiB (32Mbit) or 8MiB (64Mbit). + This can be identified by the type of flash chip below the palmrest: 4MiB is SOIC-8, 8MiB + is SOIC-16. +

+ +

+ The X200 laptops come with ME (and sometimes AMT) before flashing libreboot. Libreboot disables and removes it + by using a modified descriptor: see x200_remove_me.html (contains notes, plus + instructions) +

+ +

+ Flashing instructions can be found at ../install/index.html#flashrom_x200 +

+ +
+ +

LCD compatibility list

+

+ Unless otherwise noted (italic styling, underlined), these are CCFL 1280x800 screens with TN panels inside. + Please do advise if you spot mistakes here. +

+

+ Use the instructions at ../misc/index.html#get_edid_panelname + to get the name of your panel, then check it against the list below. If your panel is untested, then by all means + try it! (and get in touch with the libreboot project to advise whether or not it worked). +

+

+ AUO = AU Optronics. List of panels below based on + http://www.thinkwiki.org/wiki/TFT_display +

X200

+

+ Adapted from https://github.com/bibanon/Coreboot-ThinkPads/wiki/ThinkPad-X200 +

+

+ Look at wikipedia for difference between TN and IPS panels. IPS have much better colour/contrast than + a regular TN, and will typically have good viewing angles. +

+

+ These seem to be from the X200 tablet. You need to find one without the glass touchscreen protection on it + (might be able to remove it, though). It also must not have a digitizer on it (again, might be possible to + just simply remove the digitizer). +

+ +

+ If your X200 has an LED backlit panel in it, then you also need to get an inverter and harness cable + that is compatible with the CCFL panels. To see which panel type you have, see + #led_howtotell. If you need the inverter/cable, here are part numbers: + 44C9909 for CCFL LVDS cable with bluetooth and camera connections, and 42W8009 or 42W8010 for the + inverter. +

+

+ There are glossy and matte versions of these. Matte means anti-glare, which is what you want (in this authors opinion). +

+

+ Refer to the HMM (hardware maintenance manual) for how to replace the screen. +

X200s

+

+ http://forum.thinkpads.com/viewtopic.php?p=618928#p618928 + explains that the X200s screens/assemblies are thinner. You need to replace the whole lid with one from a normal X200/X201. +

How to tell if it has an LED or CCFL?

+ +

+ Some X200's have a CCFL backlight and some have an LED backlight, in their LCD panel. This + also means that the inverters will vary, so you must be careful if ever replacing either + the panel and/or inverter. (a CCFL inverter is high-voltage and will destroy an LED backlit panel). +

+

+ CCFL's contain mercury. An X200 with a CCFL backlight will (unless it has been changed to an LED, + with the correct inverter. Check with your supplier!) the following: "This product + contains Lithium Ion Battery, Lithium Battery and a lamp which contains mercury; dispose according to + local, state or federal laws" (one with an LED backlit panel will say something different). +
