HP DV6000 battery issues

Asked by Colin Downs on 2012-01-15

I'm running 11.10 on my HP DV6000 laptop and I'm having problems with the way the battery is being managed. The capacity of the battery is not being reported correctly. I've just fitted a new battery and it was reading only 70% capacity so I followed the usuall charge overnight then fully drain and recharge routine and now it is only recording caapacity of 60.8%. I feel I have already ditched two perfectly O.K batteries due to this incorrect information. The research I have done seems to suggest that the bios needs to be upgraded but as I have take out windows and reformatted the drive that doesn't look like a good idea to me. There don;t appear to any safe ways to do this under ubuntu. Has anyone else had the same problem and more to the point solved it? This is not a new problem . I'm sure it's been an issue for me since Karmic Koala.

The battery charges OK and runs the machine OK but wants to shut down well before the battery is flat.

I'm not sure it is a bug or a hardware / bios issue. I will report a bug if it helps.

I have now flashed the bios and all seems well. I will confirm and click solved after 24 hrs.

The laptop now runs O.K on battery right down to 3% and is reporting a more healthy 82% capacity. Fingers crossed.

Hmmm. It seems I still have a problem. The laptop again shut down on 76% power. Reading the reviews of the power statistics program built into the desktop utilities this eems to be the problem. If this program is unstable why is it part of the current package? I've had to uninstall it despite the waring that any future upgrades of the desktop setup will not be available,

Can you help with this problem?
