The user turned on his HP computer and got a diagnostic report showing that the surface scan failed (the report listed code HD535-2W) and that the SMART short self test failed (code HD521-2W). What does this mean and is it something that needs to be addressed ASAP? This was after he turned off his computer because the building had to shut down the electrical system. I don't know much more than that except the computer is running Vista. Is this something that I should do a support call on, or is this just possibly because the user didn't shut down his computer properly.
