Is this now solved?
-----
I figured (for future purposes also) what would be the easiest way to get information/log-files.

Step 1) Enable extras-devel
2) install powertop
3) install pastebinit
4) install rootsh
4½) disable extras-devel
5) start xterminal
6) sudo gainroot
7) powertop | pastebinit
(don't worry about warning "status: Unknown job: pmtrackerdaemon")
8) turn screen OFF
9 wait minute, turn screen ON
10) copy address, e.g.: http://pastebin.com/kvQYPTRX

Bold text means you should type them to the terminal and press enter.

Who wants make screenshots?
