I did more tests, if I do not touch my trackpoint and touchpad, this doesn't register in powertop, as in I get no interrupts. I can actually use the keyboard all day long, and that's fine. The moment I touch the trackpoint, I get: 3.83 W 6.5 ms/s 169.9 Interrupt PS/2 Touchpad / Keyb= oard / Mouse If I use the touchpad, I get: 4.46 W 7.2 ms/s 199.8 Interrupt PS/2 Touchpad / Keyb= oard / Mouse Are the drivers really that bad? Is there any way around this? Thanks, Marc -- = "A mouse is a device used to point at the xterm you want to type in" - A.S.= R.
