Hi everybody,
I got the hardware back from the HP support. The support confirmed that there has been a hardware bug in the motherboard of the system.
The motherboard has been exchanged. I have now installed Fedora-19-Mate and everything works ok.
Hence this is most probably not a Ubuntu or Linux bug. This bug can be closed.
By the way: The support by HP has been very helpful allthough the bug appeared in Linux and this is offically not supported
Thanks for everybody for the support!!!
