I just bought an Asus G75 and the battery is lasting less than 2 hours, even when doing nothing. I read somewhere that energy saving is not efficient on linux, at least by default. Is there something I can do to improve this ? Thanks
When on battery, I set Jupiter ('http://www.webupd8.org/2011/09/jupiter-applet-finally-available-for.html') to 'Power saving'. This significantly increases your autonomy.
