Laptop unresponsive after inactivity

Stand4truth · 26 Oct 2016

I recently replaced my HDD (I was getting BSOD errors, etc.) Computer runs great now, except every now and then, when I come back after it's been sitting for 15-20 minutes (sometimes as much as several hours), the screen is black, and I can't wake it up. The only way to revive it is to force shutdown (hold the power button). It's not actually sleeping, since the light around the power button isn't pulsing like it normally would. The fan is off, and I assume the hard drive is as well; I don't hear it spinning or hear it click off when I shut it down. Any ideas?

I suppose it's not hibernating- doesn't match what you're doing with the power button.

Note the time of the event, and try from an admin command prompt
powercfg /systemsleepdiagnostics
The report is written to C:\Windows\System32
See if it gives any relevant information.

Does this happen
a. If you create another user account for test purposes?
b. after a clean boot?
c. in Safe Mode?

Identical problems here on Win10 pro 1607, to wit, from Reliability monitor:
- The previous system shutdown at 1:07:22 PM on ‎10/‎18/‎2016 was unexpected.
- The previous system shutdown at 12:29:46 PM on ‎10/‎22/‎2016 was unexpected.
Both during sleep

In the first instance, there was a mouse on the black screen, but it vanished. Ctl-Alt-Del did nothing. Mouse came back and there was a blue circle for an instant and the hard drive light blinked 2-3 times. Then the sleep/power light got steady and there was no way in other than power off. Arrrggghhh
