Power Draw

[Heuristics]

I looked into the CPU settings a little and from what I now understand you need to view the cpu as having two parts that you can set the speed on, previously I thought the speed setting in the desktop applet in the lower right corner set it globally. Adding one more applet and having them set to CPU 0 and CPU 5 appears to do the trick. Setting them both to "on demand" brings power draw down to about 8-10 W. A big improvement but still far from 10 hour battery life (if lucky maybe I will get 4-5 hours with light usage). Setting both to "powersave" means it remains around 8-9 W.

I don't have anything plugged in. Any ideas what else can be done? Thank you.
