This is happening for me, too. The behaviour seems to be pretty consistently that:
a) When I am running on battery power with reasonable energy, gnome- power-manager does not recognize that I am on battery. This is confirmed because when I change the power management settings to "always show icon", as opposed to "show icon when battery is present", the plug icon shows up -- indicating no battery but instead AC power. b) When I get to low battery, suddenly the power-manager icon reappears and the management settings kick in, including power saving features like dimming screen. Also, with a recent update, my sound has disappeared. I am not sure if this is related or not, since people seem to be suggesting this could be a HAL issue. -- ubuntu doesn't notice when running on battery https://bugs.launchpad.net/bugs/39413 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
