Bug#695634: linux-image-3.6-trunk-amd64: fails to execute action (hibernate) on critical battery condition - HP Folio 13-2000
I tested this some more by observing the output of 'acpi -a'. When my
battery is low the values (percentage, time remaining) jump.
Two minutes before my notebook suddenly shut down I got 00:05:00 minutes
left, a few seconds later 00:04:34 minutes, then 00:04:46 minutes,
00:04:54 minutes… Two or three seconds before my notebook finally shut
down I got 00:04:42 minutes left. For all this time percentage was at
2%.
After plugging in the AC adaptor and booting up I got 4% and 00:04:53
minutes "until charged" (!). I disconnected the AC adaptor again – now I
still had 4%, but just 00:00:15 seconds left. However, a few seconds
later I got 00:29:31 minutes remaining again.
If 'acpi' shows ACPI information (as the manpage states), ACPI
information can't be correct. For me this seems to be a kernel bug.
Stefan.
