I’ve been using Ubuntu for quite some time, but my experience with it on laptops has been pretty shaky. Power management just doesn’t seem to cut it most of the time. If I don’t manually suspend my Macbook before I my laptop in my bag it gets smoking hot. Plus the battery life is subpar.
Today I discovered quite a jewel called powertop. It’s quite an amazing little utility. Not only does it tell you what processes/devices are sucking down the power, but it makes suggestions on how to conserve power and with a push of a button (literally) it will implement those power saving policies if you choose.
