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 / Keyboard / Mouse
If I use the touchpad, I get:
4.46 W 7.2 ms/s 199.8 Interrupt PS/2 Touchpad / Keyboard / Mouse
Are the drivers really that bad?
Is there any way around this?
Thanks,
Marc
