Hi, Thanks for your comments and help.
When I pressed the CUDA for a couple of times, about 10 to 20 seconds, there was no battery installed. I did this only after the normal CUDA procedure (5 sec. with battery) didn't work. How can I damage the motherboard without the battery? So it might be wasted money if I send my PSU in for repair? I have to get another MDD?? Best regards, Jörg.
