I was working on my SP2 this morning. When I got ready to shut the system down it gave me the option to update and shut down or update and restart. I picked the restart option and it updated and seemed to restart fine; however, I left it alone and the system went to sleep. When I tried to wake it up I got nothing. I hit the windows button a couple of times and could feel the vibration. I then tried holding down the power button to force a restart and nothing happened. Now the thing is completely dead. It won't respond to the 20 second power button reset nor the volume up + power button UEFI boot command. It had 70%+ charge when I was using it, but just to be sure I've connected it to the charger and still nothing. I have no idea what the update that showed up today was for. I used the SP2 for about an hour yesterday and it didn't download any updates. It just showed up today which is odd. Any ideas? If I can't get it working today I guess I'll try a Microsoft support call in the morning.
