I have traced the problem to the gnome-power-manger (power statistics). which is causing the system to shut down with a reasonably full battery. I have now flahed the bios which has improved the recording of battery capacity. The problem seems to occur when the laptop is booted in battery and before the discharge rate has stabilised.

Status in “gnome-power-manager” package in Ubuntu: New Bug description: 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.
