As another poster said, ac-sources include CPU frequency scaling. The bad news is that it's not very well documented, and you have to manage the CPU speed yourself. For example, I've written a short script to halve my processor speed when I'm on battery and take it even lower when the system load is low. Unless you want to invest some serious time researching it, you might want to wait for kernel 2.6. /jgt -- Actually, I hate computers. I'm just here for the EMF. -- The Cube
