Reports "Laptop battery critically low" as soon as power supply is removed

[Matthew]

Binary package hint: gnome-power-manager

This happened in release 10.04 as well, but not before then IIRC.

When I remove the power, I get a notification message (? - the thing on a black background near the top right hand corner of the screen) saying "Battery discharging // 0.03 of battery remaining (95%)". The 95% is correct (it can be higher) but the 0.03 (hours.minutes?) is nonsense.

I also get a warning dialogue saying "Laptop battery critically low // Computer will hibernate very soon unless it is plugged in." However, the battery icon on the panel shows full, and hovering over it says something like "Laptop battery 2:30 left" and that is the correct situation - the warning dialogue shouldn't appear for ages.

As far as I can see, everything in gnome-power-statistics is sensible, as are the values sent with this report.

Same problem here.
I can bypass gnome-power-manager hybernating or suspending my machine by killing it just before I disconnect power and re-starting it shortly after power has been disconnected.

[Konstantin Lavrov (lacosta)]

To stop of hybernating or suspending please try this as workaround for gpm:

gconftool-2 --type bool --set /apps/gnome-power-manager/general/use_time_for_policy false

I'll mark it as dup of 531190
