Public bug reported:
The battery life tool is incorrectly predicting the life of the battery
in Ubuntu 11.10.
This causes an unwanted shutdown when the laptop has plenty of power
left. It has done this immediately after pulling the power out of the
back of the laptop - My battery is not faulty.
Some info about my system:

I am unsure whether this is helpful. Please let me know if I can do
anything else.
Many thanks,
