Here is the reason: energy-rate: 791.681 W The same case like mine.
In fact there are bugs already filled where I already made my comment. All those bugs about that suspend or hibernation is happened after AC is removed. Here is from my comment in #516023: There are laptops that have enormous peak in energy consumption while being plug to or unplugged from AC power. Look at screenshoot from gnome-power-statistic: energy-rate is more then 0,7kW When cable was unplugged calculated time-to-empty is wrong and very small. But g-p-m reacts on this event and do what is set in prefs. To avoid suspend or hibernating I turn off time policy: gconftool-2 --type bool --set /apps/gnome-power-manager/general/use_time_for_policy false In this case 'Critical low battery' event not happen because percentage is correct. But 'Battery discharging' notification still shows wrong minutes and right percentage: 1 minute of battery power remaining (99%) Actually this energy-rate jump not g-p-m related (I filled bug 531190 against upower), but anyway this behavior of g-p-m is very annoying. -- Critial battery suspension on full battery https://bugs.launchpad.net/bugs/581630 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
