Ah, thanks for enlightening me!

And Marius, while I can't really give help or concrete solution, I can only suggest (the first thing I often do) when got problem like this is return to the store you buy and complain then try to ask the IT people / tech stuff to fix it for you (I assume you bought it from an IT or computer store). Perhaps bring along the guarantee paper, if you have done it, then I'd like to know what those people do to your laptop?
