Pressing the start button does not start the Surface...nothing happens (it is fully charged.) I believe that this may be due to the computer being stopped while installing the latest update. I didn't knowingly stop it. OR, somehow a faulty download/install process may be the culprit. The computer was installing the latest version of free Ccleaner over a previously install version. The install appeared to be stuck as it's green install line indicator kept on repeating itself and I couldn't kill the process with Process Explorer, so I think I pressed the computer's shut down button. On press the power button after shutting down, I did get the Window's window icon, and then the screen went blank and stayed blank no matter what I tried. Is there any hope?
