Yes, youre right, pressing the button has no effect. Pressing 4 seconds
powers off the laptop. Is that done via acpi too? Thought that was a
hardwarething.

The backlight files exist but they dont change anything. When i use the
sonypi driver
i can change some of the stuff with the program spicctrl. Powering of
the internal devices
works, adjusting fanspeed works, adjusting backlight just has no effects.

Did that too a few days ago, but got no answer, maybe i got the wrong
adress.

Thanks for your help, i hope it doesnt take too long to solve this,
cause in the meantime i am forced to use Windows when i am on the road,
caus it has nearly twice the runtime on battery... :)
