===high pitched noise from the board during low power states===
During low power state (cstate 3), a high-pitched "humming" noise eminates from the board. Some discussion has been made about this; suggestions include "using an oscilliscope in clever ways" (to detect where the noise is coming from to debug the issue). There are some workarounds:
Use "idle=halt" (higher power consumption) or "processor.max_cstate=2" (higher power consumption, but not as bad) kernel parameter in GRUB. These increase heat and power consumption.
Another option (for increased battery life and lower temperatures) is to use '''powertop --auto-tune''', or set 'Tunables' in powertop (without any parameters).

Note:
Boot without these options, and there will be a high pitched noise coming from the board when the system is idle.
A better workaround is to boot without these options, and run '''sudo powertop --auto-tune'''
Alternatively run powertop without arguments. Under "tunables", set all options to "Good" settings. This kills the noise.
'''By using this, power consumption falls lower: near the levels in Lenovo BIOS''' (better battery life).

works fine with GNU/Linux, some ACPI issues with Windows needs to be fixed.

Lenovo ThinkPad X60

Except where noted all status items apply to:

  • x60
  • x60s
  • x60 tablet (the digitizer also works)

Aside from pre-sales configuration (display, processor speed, optional components) the three models appear identical. It is believed that they share a single schematic.

Installation and Flashing

Wifi chipsets

Lenovo BIOS has a whitelist of approved PCI ID's for wifi cards. Coreboot does not, so you are free to use any wifi chipset of your choosing once coreboot is installed.

The Libreboot distribution lists Wifi chipsets not needing proprietary software to work.

proprietary components status

  • CPU Microcode (optional?) - works fine without. See http://download.intel.com/design/mobile/SPECUPDT/30922214.pdf
  • VGA option rom (optional): Native graphics initialization (free replacement) is also available and merged in the master repo. Note that the replacement doesn't work yet with seabios but works with grub(as a payload) or libpayload based payloads. SeaBIOS can be used with SeaVGABIOS (coreboot linear framebuffer option in seabios menuconfig) but the native graphics implementation currently lacks INT 10H and VBT.
  • EC(Embedded Controller) => you do not have to touch it(just leave it where it is)

TODO

Non-free components replacements

  • Replace the non-free VGA option rom by making native graphics init work. (native graphics available in master)
  • Create a Native graphics<->VGA option rom. SeaVGABIOS (part of SeaBIOS) might be the answer. INT 10H and VBT are missing in native graphics.
  • Make backlight work without the non-free option rom. See [1]

Windows currently doesn't boot (STOP A5 error)

Windows 7 was tested and fails to boot at the moment.

The native graphics implementation lacks INT 10H and VBT, and GRUB cannot boot it. Booting with SeaBIOS+SeaVGABIOS results in graphical corruption (and no boot).

Booting with SeaBIOS and the VGA ROM (vbios) can be used to boot it, but booting ends with the message outlined here: STOP A5

high pitched noise from the board during low power states

During low power state (cstate 3), a high-pitched "humming" noise eminates from the board. Some discussion has been made about this; suggestions include "using an oscilliscope in clever ways" (to detect where the noise is coming from to debug the issue). There are some workarounds:

Use "idle=halt" (higher power consumption) or "processor.max_cstate=2" (higher power consumption, but not as bad) kernel parameter in GRUB. These increase heat and power consumption.

Another option (for increased battery life and lower temperatures) is to use powertop --auto-tune, or set 'Tunables' in powertop (without any parameters).

Text Mode

When using native graphics instead of the VBIOS, you can enable Text Mode in menuconfig, under Display.

Disable 'Keep VESA Framebuffer'. This is for booting payloads like MemTest86+ which expect text-mode graphics.

Use this patch.

Enable backlight controls on X60 (with native gpu init instead of VGA ROM)

See x60 notes and t60 notes.

This is one way to get backlight controls working. Another method is shown in changeset 6731 on review.coreboot.org. If you use this, also apply this patch to fix uneven backlight levels: patch

Other things

  • Add support for more batteries in ACPI.
  • Make the wifi card and/or the laptop produce less heat.
  • Sometimes some dock USB port aren't initialized => fix that
  • Fix that warning:
[   14.566817] ACPI Warning: 0x00000400-0x0000041f SystemIO conflicts with Region \_SB_.PCI0.SBUS.SMBI 1 (20130117/utaddress-251)
