Q: What's the best way to optimize power management? I decided to give Ubuntu a chance on my laptop (actually, it's a netbook). This netbook is capable of 7 hours battery life on Windows 7 and I only get around 3 hours with Ubuntu. I'm a newbie, but I think that the default power management in Ubuntu is no good.
So, my question is, what's the best way to optimize Ubuntu to get as much battery as I can?

A: Try powertop.

*Install it.

*Open a terminal and run it.


See http://tombuntu.com/index.php/2008/09/09/reduce-power-usage-with-powertop/ for details.
