Description Karol Lewandowski 2009-03-12 01:12:43 UTC
Latest working kernel version:
unknown or none

Earliest failing kernel version:
Earliest _tested_ by me failing kernel was 2.6.25

Debian 4.0, 5.0

Hardware Environment:
IBM Thinkpad T21

Problem Description:
IBM's special keys (Fn-X[*]) doesn't work after resume iff laptop is resumed on battery, without AC power connected. 

[*] X can be
F4 - suspend to ram,
F7 - change video output (lcd, lcd+crt, crt),
F12 - suspend to disk.

This bug is special case of http://bugzilla.kernel.org/show_bug.cgi?id=11674

In this case special keys do work if suspend and resume is on AC power (without disconnecting AC in between).

Steps to reproduce:
1. Boot laptop on AC power
2. Suspend
3. Disconnect AC power
4. Resume
