Hang in there....this restore has helped me more than once. Have you attempted to remove ALL power and reset? Unplug EVERYTHING. The ethernet cable, the power cord. UNplug the power cord from the wall, and the laptop. Flip the laptop over and take the battery out. Flip it back over and hold the power button for 45 seconds, count it out!
Ok, put the battery back in, plug the power cord into the laoptop, then into the wall. Now try it again.
