Thought those cpu freq governors are the only way to make it energy efficient, before. Thanks for guiding me to PowerTop.
Nice tip, but this is in no way specific to Ubuntu, though your title and text implies that it probably would be.
I have been using Powertop on my laptop and netbook for awhile and it will extend the batter use time. Unfortunately one has to start it manually for each computer use.
It is a good addition to my laptop and my netbook.
I did not know about this app, looks very useful to save power. Thanks!
