I have recently bought a Dell XPS Touch. I'm dual booting Windows 7 with Fedora 16 (Verne). Right out of the box, Fedora reports 1 hour 26 minutes of battery life at full charge, while Windows reports a whopping 4 hours!!
Why is this happening? Am I missing some
acpi module or something?
A friend suggested to me that this could be due to the fact that I'm using
nouveau instead of the proprietary
nvidia driver. Does that sound reasonable?
I am now on Debian Wheezy and still the issue persists. Removed Fedora tag.
