I have noticed that my batttery life radically change when I awake my computer from sleep. When I just boot yp my computer, I have close 4 hours battery life, then if i awake the computer I have 2 hours. Weird eh?

There are two types of "sleep", one where it retains memory and trickles power and the other thats saves the memory to hard disk and totally shuts down.

http://manpages.ubuntu.com/manpages/hardy/man8/pm-action.8.html

Might be the reason? Using wrong "sleep"?

At the moment, I am using the suspend "sleep", so I should go hybrid? But how can I change it? –  Jeff Labonte Mar 13 '13 at 18:09
    
Try the commands one t a time and see the effect. But Id try the pm-hybernate one first to see if your battery doesnt loose so much charge –  Meer Borg Mar 13 '13 at 18:15
    
I tried, it is the hybrid hibernate that works best –  Jeff Labonte Mar 13 '13 at 18:16
    
Good, a solution, now to test it long term –  Meer Borg Mar 13 '13 at 18:19
