I've had this problem since 10.10. (Now on 11.10). It was just annoying up to this point, but gnome3 only lets you hibernate or shutdown for critical battery.
If I had to wager, I'd say the problem has to do with using the battery remaning charge divided by the battery *designed* full capacity, not the battery present full capacity. Batteries lose maximum charge hold over time. My laptop is about 1.5 years old, and 'lshal | grep battery' yields this: battery.charge_level.design = 62160 battery.charge_level.last_full = 31646 When I get to about 40-50% of possible charge (maybe ~14000 in units from above) the battery warnings start coming. I usually have 30 - 40 minutes (get about an hour and some change on a full charge). 14000/31646 = 40%. But if the *designed* capacity were used instead 14000/62160 = 22%, now we starting to get towards warning territory. I can use the battery down until the hardware warning comes on ok, but if i suspend and wake it with the battery at 50% (roughly) or lower, it will immediately hibernate. I can then restore it, and it runs fine. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/877556 Title: Calculation of Battery Power Consumsion was Mistake To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-power-manager/+bug/877556/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
