All-in-one caps lock blinking and won't come out of sleep

[emcee95]

After leaving my computer to go into sleep and returning to it, all I get is a black screen and the caps lock blinking slowly but continuously.  It requires a hard reboot (holding power button) to come back.  If I shut it down through the start menu, it boots up fine.  This only happens if left on to go into sleep mode.

No luck with that.  When the computer goes into sleep and I hit the spacebar to wake it up, screen remains black and the capslock button blinks.

Maybe it's hibernating after sleep. Waking from hibernation requires pressing the power button.
