Why does my computer get less battery life with Ubuntu compared to Windows?
After upgrading from Ubuntu 10.10, my battery life has decreased dramatically.
There was a bug in Ubuntu 10.10 where the Load Balancing Tick and Kworker would interrupt and wake-up the cpu too much, and this wasn't normal. I applied a gnome-power-manager fix back then, following this question, which leads to this bug report, and battery life increased to 3.5 hours.
I'm getting around two hours of battery-life in Natty, and calling Intel's powertop reveals that this bug is back. Is there a fix for Natty yet?
I have a Core 2 Duo ULV, Thinkpad Edge 13
