Power button don't work

If the power button don't shut the computer off, probably it's a permission problem with the file .ICEauthority. To determine the location of the file, manually execute the following command:

/etc/acpi/powerbtn.sh

The above command will show something like that:

WARNING: ICE authority file /root/.ICEauthority is not readable by you!
Please check permissions or set the $ICEAUTHORITY variable manually before calling dcop.

Remove the offending file to fix the problem.
