Well... THANK YOU...... mine has been sitting dead in my drawer for 6 months. Tried this and it worked first try!!! Microsoft wanted $599 to fix this but all my files would be gone! Well atleast i can transfer all my files into my macbook now ;)
What i did was to do the 'power and volume trick' while pulling the unit inwards at 45 degrees angle... with type cover intact. I guess that was what other users meant by 'bending'. However it worked for me. My SP3 is working fine now and I'm so relieved! Do try that. It is such a waste to keep your surface in the drawer.
