Any idea. > same experience. But I let the software decrease the cpu throttling stepwise on load. I mean not jumping straight between 800MHz and 1.6GHz nor force it to be 800MHz. For powersaving I gained 1 hour (from 5 hours to 6 hours) by blacklisting all kernel modules I don't want to be started on boot on my Asus 1000H. E.g. not staring web camera support on startup. Experiment with this on your computer. Best wishes Preben
