> 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.
