Roger mentioned problems with his new laptop trying to get power savings up and running. I happened to run across this in my day to day research so thought I would pass it along to others. I have not used this myself though it does look rather useful.
- Brian PowerTOP Computer programs can make your computer use more power. PowerTOP is a Linux tool that helps you find those programs that are misbehaving while your computer is idle. The application that misbehaved the most was the Linux kernel. However, as of version 2.6.21, the Linux kernel went tickless, and no longer has a fixed 1000Hz timer tick. The result (in theory) is huge power savings because the CPU stays in low power mode for longer periods during system idle. http://lesswatts.org/projects/powertop/
