Description vk 2009-01-28 04:50:36 UTC 
Description of problem:
Gnome-power-manager shows my laptop has 1hour+10 minutes of juice when fully charged. It's almost *triple* this amount on Windows XP, SP3.

Version-Release number of selected component (if applicable):
2.25.2

How reproducible:
A general continuous problem.

Additional info:
-attached

Possible solutions:
- add an option to the gnome-power-manager interface to create battery *profiles* based on;
>> screen brightness
>> cpu level (pick between 1 - 6), or option to use dynamic frequency
>> defining conditions for standby, hibernation, screen dim, screen lock actions

- extending powermgr (http://sourceforge.net/projects/powermgr) and creating a panel applet for it
>> the last update was in 2005, so there would be some serious work involved

Sounds like a kernel problem. Can you try unloading modules and seeing what causes the biggest drops?
