How do you do the analysis after running powertop in the background?

Sorry, didn't notice the reply; if you let it running for a few while eventually it'll collect enough samples to show you the power consumption of the processes you have running in the terminal UI. Then you just look at the top ones in the list and see if there's a way to reduce power consumption, or quit using them altogether. I haven't used it enough to figure out how the reports work.
