My laptop worked flawlessly before upgrade to Windows 8.1 from 8. Now when I close the lid of my laptop and it goes into hibernation, it will not wake again. The LED lights seem to work properly but I don't get any video. I have to hold the power key to turn off then turn it back on again.
It wakes from sleep properly.
All Windows Updates have been installed. There are 2-3 items in the Device Manager that do not have compatible 8.1 drivers, but I believe those are security related items like fingerprint scanner.

This is something of a longshot, but try disabling hibernation, restarting, reenabling hibernation, restarting, and trying the open/close process again. It's possible the hibernation file is corrupted somehow and on trying to restore it, Windows dies.
Now try closing the lid and waiting a few seconds after it turns off before opening the lid again.
