Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

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?

What version of ubuntu? what graphics card do you have? Are you using any additional graphics drivers? Do you use any special grub boot options? –  fossfreedom Sep 30 '11 at 18:04
    
@Matjaž Finžgar Your brand and model of netbook would be useful as well, so we can look up its complete specs. –  WarriorIng64 Nov 7 '11 at 5:32
    
This question should instead be filed as a bug report, and as such is off-topic, thanks! Instructions here. –  Bruno Pereira Mar 4 '12 at 10:08

Try powertop.

  1. Install it.
  2. Open a terminal and run it.

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

That looks like an interesting article, but do you think you could edit some of the main suggestions back into your question so we can avoid potential linkrot issues? Thanks! –  WarriorIng64 Nov 7 '11 at 5:35
