MD101LL/A with no sound behaves unusually

Texto:

Hi All!

Got an MD101LL/A with audio icon greyed out, i.e. "no audio devices found".   Usually this would be resolved by flipping over the digital audio in the headphone jack, but strangely, sticking a screwdriver in the headphone jack makes the laptop fall asleep.  Removing it wakes it up.  The audio icon stays greyed out and does not change even temporarily.  The board looks clean -- I removed it and see nothing unusual.

Any ideas?

Thanks
