Power management

Fan control

There are some discussions concerning overheating-related shutdowns when running under full load (video encoding, etc) ([1] [2]).

ThinkPad Fan Control contains instructions to install tpfand as a custom replacement for hardware (bios-) fan control.

Bootloader kernel parameters

Add these kernel parameters to make use of power saving mechanisms which are turned off by default because of reported instabilities.

Warning: These options can cause instability on your system! Try them and remove them if you are experiencing problems.

Firmware

Using non-Lenovo Network cards

If you get

 1802: Unauthorized network card is plugged in - Power off and remove the miniPCI network card.

on boot, that means your BIOS does not include that specific card in its whitelist. The only option is either coreboot or a custom BIOS with the whitelist "disabled".

Such a bios can be found at this forum post at mydigitallife.info.

You can either use Windows to flash, or a DOS boot disk with phlash16.exe and the 02C2100.ROM from the forum post's rar like I did. To do it this way, first upgrade the BIOS to the latest version from Lenovo. Then, rename "02C2100.ROM" to "BIOS.WPH", save it to your DOS boot disk and run phlash16.exe.
