I got an interesting problem that I am not sure where to do with. I have a laptop running Debian 6 / Ubuntu 11.10. I have it dual booting. The laptop is a Toshiba m645 s4045.
The problem is something to do with the battery manager in Linux or the power management chip in the laptop.
When I plug in the laptop it charges fine, when I unplug the laptop with a full charge it warns that the battery is critically low and the machine will shutdown soon. Then the battery monitor tells the battery will last 8 hours. Then the battery evens out after a few minutes and reports a lifespan of about 2 hours which seems appropriate for the size of the battery, its a 6 cell battery.
What the heck is going on with my laptop? I thought it was the battery (the original one) so I bought another battery, this did not solve the problem.
Could it be Linux acting up? Could it be hardware?
HELP!!
