The same issue happens in Hardy and I think this bug is present since 2006 (see also bug #159407, opened on 2007, and marked as invalid because of lacking of info).
1) I start the PC with battery plugged in: " ma...@dominus:/proc/acpi/ac_adapter/ACAD$ cat state state: off-line ma...@dominus:/proc/acpi/ac_adapter/ACAD$ cat ../../battery/BAT1/state present: yes capacity state: ok charging state: discharging present rate: 1574 mA remaining capacity: 879 mAh present voltage: 10730 mV " 2) I hibernate the PC 3) I unplug the battery and I plug-in in the ac-power 4) I startup the PC 5) " ma...@dominus:/proc/acpi/ac_adapter/ACAD$ cat ../../battery/BAT1/state present: yes capacity state: ok charging state: charged present rate: 0 mA remaining capacity: 0 mAh present voltage: 0 mV ma...@dominus:/proc/acpi/ac_adapter/ACAD$ cat state state: on-line " You will see that at last the ac-power is recognized as on-line (and this is ok) but also the battery is recognized as present (and this is not ok). The gnome-power-manger plugin still shows battery icon even if, if you move the mouse cursor over the icon, you can read that the PC is running with ac-power and the battery state cannot be read at that moment. The same issue, but obviously in the opposite way, happens if you start, at first, the PC with ac-power and then, after hibernation, you plug-in the battery and you unplug ac-power. ** Changed in: gnome-power-manager (Ubuntu) Status: Invalid => New -- After hibernate: Battery not correctly recognized/displayed in Panel applet https://bugs.launchpad.net/bugs/73750 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
