My SP3 was having some weird mouse pointer problems this morning (with my Logitech mouse). I decided to just restart the computer and see if that cleared up the problems. The machine cleanly shut down and then... never came back! I pressed the power button - nothing. I held down the power button for ten or fifteen seconds, and still no power. I set it aside for an hour and tried again - it still wouldn't come back. I had a dead tablet. The power supply was at home. When I got home I plugged it in and tried the power button again, and it powered up. It still had a full charge, by the way. Has anyone seen anything like this? I can't risk being on the road with a dead computer. My faith is shaken. I'm wondering if I should return it.
