Watching Your Power Consumption With Powertop On Fedora 7
Author: JT Smith
Powertop is a command-line tool released by Intel that shows you the power consumption of the applications running on your system. It works best on notebooks with Intel mobile processors and can help you find out the programs that put a strain on your notebook battery. It requires kernel 2.6.21 or newer with tickless idle enabled (CONFIG_NO_HZ) (which is currently available for 32-bit kernels only). Fedora 7 comes with a 2.6.21 kernel by default, so we can use Powertop on it.
