PowerTOP is a Linux tool that finds the software
component(s) that make your laptop use more power than
necessary while it is idle. As of Linux kernel version
2.6.21, the kernel no longer has a fixed 1000Hz timer
tick. This will (in theory) give a huge power savings
because the CPU stays in low power mode for longer periods
of time during system idle.
However... there are many things that can ruin the party,
both inside the kernel and in userspace. PowerTOP combines
various sources of information from the kernel into one
convenient screen so that you can see how well your system
is doing, and which components are the biggest problem.
