I've been struggling with this issue for months now, and I thought I was able to replicate it but I am not.
Every time I wake from sleep after several hours the computer wakes, but the screen is black. I can access the system remotely and the GPU is missing from the device manager and nothing will enable it other than multiple hard reboots.

Troubleshooting Steps Done:
Nothing seems to help. I can wake it if it's been less than 6-8 hours, and it comes up fine, if not kind of taking a bit longer than I would anticipate. Usually 10-15 seconds, but if its after several hours the fans will ramp up and nothing on the screen.
I can use Teamviewer or RDP to remote in, the machine is up and awake, but the GPU is gone. Nothing is listed at all in device manager. It's like the GPU didn't wake although the fans are on and the LED is on.
