title: ThinkPad X200

Introduction
|
||
|
|
============
|
||
|
|
|
||
|
|
It is believed that all X200 laptops are compatible. X200S and X200
|
||
|
|
Tablet will also work, [depending on the configuration](#x200s).
|
||
|
|
|
||
|
|
It may 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 the ME (and sometimes AMT in addition)
|
||
|
|
before flashing libreboot. Libreboot disables and removes it by using a
|
||
|
|
modified descriptor: see [../install/ich9utils.md](../install/ich9utils.md)*
|
||
|
|
(contains notes, plus instructions)
|
||
|
|
|
||
|
|
Flashing instructions can be found at
|
||
|
|
[../install/\#flashrom](../install/#flashrom)
|
||
|
|
|
||
|
|
EC update {#ecupdate}
|
||
|
|
=========
|
||
|
|
|
||
|
|
It is recommended that you update to the latest EC firmware version. The
|
||
|
|
[EC firmware](../../faq.md#ec-embedded-controller-firmware) is separate from
|
||
|
|
libreboot, so we don't actually provide that, but if you still have
|
||
|
|
Lenovo BIOS then you can just run the Lenovo BIOS update utility, which
|
||
|
|
will update both the BIOS and EC version. See:
|
||
|
|
|
||
|
|
- [../install/#flashrom](../install/#flashrom)
|
||
|
|
- <http://www.thinkwiki.org/wiki/BIOS_update_without_optical_disk>
|
||
|
|
- [X200, X200s, X200si BIOS Update](http://pcsupport.lenovo.com/au/en/products/laptops-and-netbooks/thinkpad-x-series-laptops/thinkpad-x200/downloads/ds015007)
|
||
|
|
- [X200t BIOS Update](http://pcsupport.lenovo.com/au/en/products/laptops-and-netbooks/thinkpad-x-series-tablet-laptops/thinkpad-x200-tablet/downloads/ds018814)
|
||
|
|
|
||
|
|
NOTE: this can only be done when you are using Lenovo BIOS. How to
|
||
|
|
update the EC firmware while running libreboot is unknown. Libreboot
|
||
|
|
only replaces the BIOS firmware, not EC.
|
||
|
|
|
||
|
|
Updated EC firmware has several advantages e.g. better battery
|
||
|
|
handling.

||

|
Battery Recall {#batteryrecall}
|
||
|
|
=========
|
||
|
|
[On 21 April 2015, Lenovo expanded a recall on Lenovo batteries found in some ThinkPad models, which includes the X200 and X200S.](https://pcsupport.lenovo.com/cr/en/solutions/hf004122)
|
||
|
|
To find out if you are affected, use [this Lenovo tool.](https://lenovobattery2014.orderz.com/)
|
||
|
|
Lenovo advises that owners of the recalled models "should turn off the system, remove the battery,
|
||
|
|
and only power your ThinkPad by plugging in the AC adapter and power cord."
|
||
|
|
Upon battery verification, Lenovo will replace recalled batteries free of charge.
|
||
|
|
Battery replacement instructions for the X200/X200s are found [on this page.](https://pcsupport.lenovo.com/cr/en/parts/pd003507/)

Compatibility (without blobs) {#compatibility_noblobs}

||
|
|
|
||
|
|
### Hardware virtualization (vt-x) {#hwvirt}
|
||
|
|
|
||
|
|
The X200, when run without CPU microcode updates in coreboot, currently
|
||
|
|
kernel panics if running QEMU with vt-x enabled on 2 cores for the
|
||
|
|
guest. With a single core enabled for the guest, the guest panics (but
|
||
|
|
the host is fine). Working around this in QEMU might be possible; if
|
||
|
|
not, software virtualization should work fine (it's just slower).
|
||
|
|
|
||
|
|
On GM45 hardware (with libreboot), make sure that the *kvm* and
|
||
|
|
*kvm\_intel* kernel modules are not loaded, when using QEMU.
|
||
|
|
|
||
|
|
The following errata datasheet from Intel might help with investigation:
|
||
|
|
<http://download.intel.com/design/mobile/specupdt/320121.pdf>
|
||
|
|
|
||
|
|
Anecdotal reports from at least 1 user suggests that some models with
|
||
|
|
CPU microcode 1067a (on the CPU itself) might work with vt-x in
|
||
|
|
libreboot.
|
||
|
|
|
||
|
|
LCD compatibility list {#lcd_supported_list}
|
||
|
|
----------------------
|
||
|
|
|
||
|
|
LCD panel list (X200 panels listed there):
|
||
|
|
<http://www.thinkwiki.org/wiki/TFT_display>
|
||
|
|
|
||
|
|
All LCD panels for the X200, X200S and X200 Tablet are known to work.
|
||
|
|
|
||
|
|
The X200 Tablet has a screen rotation button on its bezel. Depending
|
||
|
|
on the operating system it might or might not rotate the screen, the
|
||
|
|
digitizer (stylus), or the trackpoint accordingly. Utilities are
|
||
|
|
provided to fix this at *resources/utilities/x200t-screen-rotation* in
|
||
|
|
the libreboot git repository.
|
||
|
|
|
||
|
|
### AFFS/IPS panels {#ips}
|
||
|
|
|
||
|
|
#### 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).
|
||
|
|
|
||
|
|
- BOE-Hydis HV121WX4-120, HV121WX4-110 or HV121WX4-100 - cheap-ish,
|
||
|
|
might be hard to find
|
||
|
|
|
||
|
|
- Samsung LTN121AP02-001 - common to find, cheap
|
||
|
|
|
||
|
|
*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](#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? {#led_howtotell}
|
||
|
|
-------------------------------------
|
||
|
|
|
||
|
|
Some X200s 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).
|
||
|
|
|
||
|
|
CCFLs 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!) say
|
||
|
|
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).

[shows](http://www.coreboot.org/Motherboard_Porting_Guide) how to
|
||
|
|
collect various logs useful in porting to new boards. Following are
|
||
|
|
outputs from the X200:
