power management in ubuntu for laptop
Hi
I have the following problem, when I try to work on battery in my laptop, ubuntu consumes power very rapidly and after couple of minuts my laptop is out of battery power.
Previosly had win xp on that machine and win was able to manage battery power much better then linux.
Is there any way I can improve it under linux ?
thx for help.
