Re: [Trisquel-users] Squeezing battery time

Depending on how you use the box, underclocking the main cpu and the video  
card cpu could be helpful as well. These however can ruin your hardware, so  
be careful if you do try them.

I have an ATI video card and use the package rovclock to underclock it when  
doing something like reading a long text and when not plugged to AC. I can  
drop the clock from 300 MHz to something like 50 MHz. Haven't got any hard  
data to quantify power savings though.
