Why does my computer get less battery life with Ubuntu compared to Windows?
I'm using Ubuntu 12.10 with Gnome 3.6 on a Dell Inspiron N5010 laptop, but I have a problem with the power handling/battery. As soon as I disconnect my charger, the battery starts discharging from an indication of 51% and it lasts for only 1 hour. Compared two hours in Windows 7, this is a major difference.
I've installed Jupiter and I don't see any change. I'd appreciate some help on this, as I would like to keep using Ubuntu now.
