PC won't sleep - have tried EVERYTHING I KNOW OF.

Windows 8.1 Won't go to sleep automatically

I've done quite a bit a research and nothing seems to support my case. My computer will GO to sleep and STAY asleep if I ask it to as in, I manually put the computer to sleep. But if I don't manually put it to sleep, it won't go to sleep, only the monitors turn off and the computer is still running. I checked powercfg and it doesn't say anything is keeping my system from sleeping. I also checked all my power options and all of them are set to sleep after 20 minutes of inactivity. “


I have the same issued and have literally tried EVERYTHING. ALL the above. ( except BIOS - cant imagine how that would be causing this? ) I have no file sharing set up. I've checked every powercfg option and even did one where you run a power report that generates an html file. I have the file and there are errors, I think, but nothing that could do this. Help would be appreciated.

From just now: ( and the /energy test doesn't show anything that would keep it awake either! )
BUT every time I do a Windows update, it will go to sleep automatically for maybe a few hours or a day, then go right back to not automatically sleeping again! This is driving me bat crazy!

Think I finally got to the bottom of this.

I had to allow selective suspend, then run powercfg /energy again.

I don't know why the resulting energy-report file is so hard to work with. The only browser I could even view it with was Chome.

It cant be copied or sent as an attachment.

Anyway, here's what I got with the latest test now - the meat of it:

[h=3]Analysis Results[/h][h=4]Errors[/h]System Availability Requests:System Required Request
The device or driver has made a request to prevent the system from automatically entering sleep.

Now the question becomes what can be done about it, and whether Realtek gives a hoot, or has any better drivers?

These are apparently NOT settings I can get to, to change them.
