Advanced Power Management in Ubuntu
The default power management system that is present in ubuntu is very basic and provides very limited functionality. If you need more advanced features i will show an application called Kpowersave which is part of the KDE gears package. Kpowersave is easily found in Ubuntus repositories so instaling it is not too difficult.
When you first launch Kpowersave you get an icon in your panel like so:
Clicking on the icon shows you an information dialog box showing you various options such as.
1) The power scheme selected
2) The CPU frequency policy set
3) Remaining Battery Power and voltage consumption
