I had the same thing happen to a desktop PC. However my experianced was a dead machine.
When I took it apart to check the power supply I found pennys in the case.
Long Story Short, - My two year old was using my PC as a Piggy Bank!
Do you have kids?
No kiddies for me, nor have I really been around any since I've owned the laptop. In any case, it really appears to be intentional.
I did NOT (willingly) purchase a refurb. I may have to get my angry face on.
