Computer partially wakes from sleep?

Cruise · May 11, 2021

I'm having an issue with my computer not waking from sleep. I have my computer both scheduled in task manager and as an idle setting to go to sleep. Unfortunately, when I go to wake it back up with either the power button and/or the mouse and keyboard, it only partially comes back on. What I mean by that is that the RGB, lights, fans and everything inside the computer itself seems to be waking up, but neither of my displays come back on, there's no activity on the HD light and the mouse and keyboard will wake up when you press a button but then go back to sleep seconds later. The reason for the "partial" in my Title is exactly how it sounds. It looks like the computer only partially wakes up.

Some notes:

1. Putting my computer to sleep is a new endeavor. I actually had the sleep function off for as long as I can remember because I run a Plex server on my PC. Recently, I decided I do not need my computer running 24/7 just for that and would rather save some electricity.

2. Sleep worked just fine for the first few days that it actually went to sleep. There was sometimes it was still awake overnight (Come to find out, this was an issue caused by GeForce Experiences overlay which was resolved when I turned it off). Then I started finding the computer in this half awake/half asleep mode when I would wake up or get home from work.

3. The only way I found to get out of this is to hold down the power button and force the computer off. Then it would post normally about half the time but the other half the BIOS would say that there was an improper shutdown and I would need to check settings, blah, blah before starting normally.

4. I know I hinted at this above, but I do want to point out that there seems to be no software activity when this happens. I originally thought it may be a GPU sleep issue, but the lack of HD activity, the mouse/keyboard only staying on for a couple seconds on button presses points in a different direction, possibly?

5. PSU is a Corsair HX850.

I have to be honest, when it comes to sleep functions on a PC, I only know enough to turn them on/off and how to diagnose software keeping a PC awake and that's about it. My Google skills haven't turned up anything useful either. I'm kind of at a loss with this.

Check the settings for power states, either your drive or something else isn't waking.

So, I checked my power states and it was only listing S3 as available to the system. Not that this is bad, but it made me crawl down a rabbit hole wondering why even hibernation wasn't available. I eventually ended up in the UEFI and turned off all UEFI controlled power functions and then shifted anything I could over to OS controlled or disabled any extra power control features altogether, if OS control wasn't an option. I also noticed I had a UEFI firmware update and did that at the same time. Right now, it's working. I put the system to sleep and immediately after waking it, my login screen came on. I'm not sure if there is/was a bug in the UEFI power controls, it didn't mesh well with windows or I just simply needed to update my firmware. Either way, hope this helps anyone running into the same issue.
