Getting your computer to use the least amount of power can be problematic. This site provides information on reducing power usage, tips, and tricks for Intel-based computers running Linux.

You can download use PowerTOP, which 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.

As a first step, Intel is releasing PowerTOP, a tool that helps you find what software is using the most power. By fixing (or closing) these applications or processes, you can immediately see the power savings in the tool. You’ll also see the estimated time left for battery power if you are running a laptop. The Tips&Tricks page has fixes for a lot of the issues that are already found. Join our mailing list to participate in this effort to get Linux to use less power.
