AC is plugged in for first set of attachments and is unplugged (running on battery) for the second set of attachments.

Devicekit-power is reporting that the battery is in an identical state for both sets of attachments. It seems that GPM is reporting what DKP is telling it, so I'm labeling this bug for devicekit-power.

OK, have apport-collected again for devicekit-power.

gpm is giving correct information today after this morning's resume from suspend, and I can see historical charge statistics for the last week.

But again it's not working; seems to break when I leave my notebook charging to full capacity then remove AC.

My AAO A150 doesn't even charge my battery and gpm is showing (on mouseover) "Battery if fully charged" but on mouseclick is shows "Battery in laptop: 0.0%".

The led that indicates the power just keeps blinking orange, no stable light at all. Never reaches green either.
Worked like a charm in hardy (8.04).

Mine battery also stopped charging:

So, after a very long time search for solutions, I think this is a problem for almost ***Acer*** laptops. Hmm, hope Ubuntu dev team should consider this is a serious problem. It prevents your people to use Ubuntu on an Acer machine.

Status changed to 'Confirmed' because the bug affects multiple users.
