Software Environment:

Linux alface 2.6.12-1-686 #1 Tue Aug 9 13:00:08 UTC 2005 i686 GNU/Linux

Problem Description:

My batery status is completely messed up. The state does not seem to update. I
turned on the laptop with ac pluged, unpluged it and the gnome batery monitor
showed 99% immediately and correctly showed the 'on batery' state, the screen
lowered the light. Then I replug the ac cable and I get the 'ac on' state shown
by the gnome monitor but no indication of it being recharged. If I unplug the ac
cable and plug it again the status is updated, but not always. Sometimes the
screen light will not even be increased when the ac plug is on.

Monitoring /proc/acpi/battery/BAT1/state confirms the symptoms shown by the
gnome batery monitor. I first noticed this problem on linux 2.6.9 and 2.6.10,
2.6.11 and 2.6.12 also have it.

Right now I have pluged the cable and the gnome batery monitor shows 94% and 'on
battery' state, which is not correct, of course. The light has not been
increased and this is how /proc/acpi/battery/BAT1/state looks like:

$ cat /proc/acpi/battery/BAT1/state
present:                 yes
capacity state:          ok
charging state:          charged
present rate:            0 mA
remaining capacity:      3584 mAh
present voltage:         16736 mV

Ah, the batery led on the front of the laptop is orange, meaning it should be
recharding. Checking /proc/acpi/battery/BAT1/state again shows no change,
though. Unpluging and pluging the cable again made the gnome batery indicator go
to 97% now, but still shows 'on battery' state. /proc/acpi/battery/BAT1/state
now shows:

$ cat /proc/acpi/battery/BAT1/state
present:                 yes
capacity state:          ok
charging state:          charged
present rate:            0 mA
remaining capacity:      3680 mAh
present voltage:         16768 mV

I don't know what kind of information could be useful. If you tell me how to
grab more information that could help I'll gladly do it.

Thanks,
