Linux tool to find out what is using power on a laptop

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.

Package version:1.11-1+squeeze1


What's eating the battery life of my laptop? Why isn't it many more
hours? Which software component causes the most power to be burned?
These are important questions without a good answer... until now.

The Linux 2.6.21 kernel introduces the so called tickless-idle
feature. This feature allows the processor to be really idle for long
periods of time, rather than having to wake up every millisecond
