Hi, Christophe's thread abour Ext3 made me think a bit more... When being on battery power, I could put my CPU to low speed to save some power. That should work with pmud. But is there a way to put the machine into snooze, when it is idling for a given time? I think that it should check for input devices' idle only, because there are always some programs working in background which I don't always want to stop before. Bye, Claas
