frequency

The Ubuntu repos have Intel powertop software. The software is a quick terminal based interface providing information about your computers power consumption. The software is designed to report on Atom based CPUs. sudo apt-get install powertop Run with: sudo powertop Press “w” when the softwasre tells you and your system will self optimize a bit. It recommends operating your CPUs on dynamic frequency mode, but when on battery power its obviously better to fix the frequency at the lowest value. Also reducing the brightness of your screen will substantially reduce power consumption.
