Manage Ubuntu’s System Power State

The problem: On battery power, a warning message pops up telling you your battery is critically low. Even if you have time to plug in the mains, that’s ignored and the PC shuts down.

I was using ubuntu 8.10 when I did this to solve the problem.

Here’s the solution ..

Open the Configuration Editor from the Terminal:-

[text]gconf-editor[/text]

Cascading through the menu, set up or change the following keys:

[text]
/apps/gnome-power-manager/general/use_time_for_policy (false)
/apps/gnome-power-manager/thresholds/percentage_low (12)
/apps/gnome-power-manager/thresholds/percentage_critical (8)
/apps/gnome-power-manager/thresholds/percentage_action (5)
/apps/gnome-power-manager/actions/critical_battery (hibernate)
[/text]

Now, when the battery reaches 12% Gnome shows a “low battery warning”, at 8% a “Critical battery warning” and at 5% the system hibernates.

Thassit. You can go now.
