Comment 2 Dave Jones 2011-04-22 22:52:12 UTC 
This line is the important one..

"Your BIOS is broken"
Comment 3 Gerhard 2011-04-23 21:29:53 UTC 
But with Fedora 13 I never got this abrt-message.
Also I now have problems waking up my machine after standby mode and sometimes it hook off while shutting down. :-/

All problems occur since Fedora 14.
Comment 4 David Woodhouse 2011-04-23 21:44:24 UTC 
Your BIOS is broken. Sucks to be an HP customer.

If an update isn't available, I recommend you take it back to wherever you got it from, and demand a refund.
Comment 5 Gerhard 2011-04-23 22:02:58 UTC 
No chance to give it back. :-/

But maybe it is possible to go the same way as there:
