Hej!

I'm running gentoo on my Thinkpad R51e which works real fine. WLAN,
Ethernet, Sound, Suspend to RAM, Video (I only need 2D), etc, no problem.
But I have a hard time optimising life on battery. For starters the switch
from ac to battery doesn't lead to execution of scripts in /etc/acpi :-(

How do I debug this? It seems acpid never reports the switch as event:

Apr 18 08:53:55 asterix acpid: received event "processor CPU 00000081
00000000"
Apr 18 08:53:55 asterix acpid: notifying client 4346[104:443]
Apr 18 08:53:55 asterix acpid: notifying client 4669[0:0]
Apr 18 08:53:55 asterix acpid: client has disconnected
Apr 18 08:53:55 asterix acpid: notifying client 4669[0:0]
Apr 18 08:53:55 asterix acpid: client has disconnected
Apr 18 08:53:55 asterix acpid: completed event "processor CPU 00000081
00000000"
Apr 18 08:53:55 asterix acpid: client connected from 4669[0:0]
Apr 18 08:53:55 asterix acpid: 1 client rule loaded
Apr 19 01:34:16 asterix acpid: client connected from 13718[0:0]
Apr 19 01:34:16 asterix acpid: 1 client rule loaded
Apr 19 08:39:10 asterix acpid: received event "processor CPU 00000081
00000000"
Apr 19 08:39:10 asterix acpid: notifying client 4346[104:443]
Apr 19 08:39:10 asterix acpid: notifying client 4669[0:0]
Apr 19 08:39:10 asterix acpid: notifying client 13718[0:0]
Apr 19 08:39:10 asterix acpid: completed event "processor CPU 00000081
00000000"
Apr 19 08:39:10 asterix acpid: client connected from 4669[0:0]
Apr 19 08:39:10 asterix acpid: 1 client rule loaded

01:34 was start of suspend-to-RAM and 08:39 the resume. There are never any
other events logged! I've added logger lines to the scripts
in /etc/acpi/actions (from laptop mode) but those aren't executed.

The state variable in /proc/acpi report the switch just fine:

vitus@asterix:~$ cat /proc/acpi/ac_adapter/AC/state
state: on-line
vitus@asterix:~$ cat /proc/acpi/ac_adapter/AC/state
state: off-line
vitus@asterix:~$ cat /proc/acpi/ac_adapter/AC/state
state: on-line

Module thinkpad_acpi is loaded, controlling fan, volume and brightness
works. Where do I start investigating? acpid, hald, thinkpad_acpi?

PS: thing is this notebook can't really save power (celeron-m, atheros w/o
powersave mode), but this is another story.
