Description Filipp Andjelo 2009-12-24 01:34:28 UTC

Following snippet of dmesg explains the problem better, than I'd ever could:

# dmesg | grep ACPI
...
ACPI: AC Adapter [AC] (off-line)
ACPI: Battery Slot [BAT0] (battery absent)
...

So AC adapter isn't plugged in and battery is absent, so where does this thing gets its power from? I think we have a best exampt of "perpetuum mobile" here :)
The notebook is one of Belinea o.book 1301 series. Say, which additional information is needed to handle this bug.

Thx.

Comment 8 Filipp Andjelo 2009-12-24 10:05:49 UTC

Here is the information you've requested. I've noticed, that there is a difference between boot with AC adapter pluged in or not.

Comment 9 Filipp Andjelo 2009-12-24 12:49:34 UTC

The problem seems not to exist with kernel 2.6.32 anymore.

I have exactly the same problem with my Belinea o.book 1301 - and it happens with Linux 2.6.32 as well as with Linux 2.6.37-rc5.

dmesg output

I booted with the adapter plugged in, which was not detected. At 126 I unplugged it and at 142 I plugged it in again which was correctly detected.
