55.3% (287.1) <interrupt> : extra time interrupt
19.4% (100.5) <interrupt> : eth0
13.1% (68.2) <interrupt> : nvidia
--the rest are below 2%(8)--
Powertop information during regular use:
44.3% (445.9) <interrupt> : PS/2 keyboard/mouse/touchpad
18.3% (184.5) <interrupt> : extra time interrupt
10.1% (101.4) artsd : schedule timeout
8.9% (100.6) <interrupt> : eth0
7.0% (70.6) <interrupt> : nvidia
5.4% (54.8) amarokapp : schedule timeout
4.2% (42.2) <kernel IPI> : Rescheduling interrupts
2.8% (28.0) amarok : schedule timeout
1.7% (17.3) <interrupt> : HDA Intel
1.4% (13.9) X : schedule timeout
--the rest are below (13)
Any ideas on what my be causing the loss of battery life and how to fix it would be sweet.
