I've been receiving the above message for the past few weeks but haven't been able to find a problem.
I ran the troubleshooter from the 'click here' in the red error box but this didn't find anything wrong.
I also separately ran the troubleshooter for the power as I did notice the battery had seemed to have drained quickly. Again, no problem identified.
The screen detaches and reattaches without any apparent problem.
It just seems odd that the computer seems to think it has detected a problem but then doesn't seem to know what it is :P
