That might be a BIOS issue. I guess there is no BIOS update available
for your machine?

If the problems still occur on the newest BIOS, the debugging you need
to do is described on

Depending on your findings we might get an idea how to fix your issue.
So please report back your test results.

Best regards
Uwe
