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.

webspace, its quite a long file.

The URL is http://www.twisted-artwork.de/vault/linux/acpidump.txt

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... :)
