Public bug reported:
Binary package hint: gnome-power-manager
In Karmic, gnome-power-manager does not detect the current charge of the
battery while it is discharging. To summarize:
1. Disconnect power cord:
2. Note that gpm's tray icon detects that the power cord's disconnected, and
says 99% battery
3. Wait a while
4. Note that the battery charge monitor applet shows the charge dropping, while
the tooltip of gnome-power-manager shows the battery still full.
5. Plug the cord back in.
6. Note that gpm's tray icon detects that the power cord is plugged back in,
and suddenly knows the correct charge.
To be make things even clearer, I shall attach a screenshot of the power
graph, with data points enabled. Basically, the charge level of the
battery is only detected when the power cord is disconnected, when it's
connected, and when it's charging, but not when it's discharging. This
is dangerous as the user will not be warned when the power hits
critical level (because gpm thinks it's still 99%), and the system will
not auto-hibernate despite being configured to do so, resulting in
"sudden death" of the computer with the battery completely exhausted.
