Acer desktop TC-780A won't enter sleep mode naturally

I’ve been running windows 10 for a little while now and thus far have had little to no issues. Recently the computer won’t go to sleep unless I do it manually.

I have tried lots of things to fix this and have hence probably forgotten a few but I’ll write down what I can remember. 

1) Adjust sleep times in power management 
2) Go into advanced Power settings and checked everything there. Change the settings for media at the bottom and the allow wake timers settings
3) Go into device manager and stop the Ethernet etc. from waking the computer
4) Reset all power settings to default, just in case
5) Update drivers including intel drivers from their website
6) Ran powercfg /energy in command prompt. The latest reports don’t say that anything is preventing the comp from sleeping… 
7) Disconnected all USB devices to no avail
8) tried changing Power plan from "performance" to "balanced"

I know I’ve tried other things but nothing has worked. When I first installed the machine it would go to sleep naturally. The current version of Windows 10 (64 bit) is 10.0.0.18362 build 18362. Not sure at what point in Windows 10 updates the problem started.

I’d love some help with this. Please let me know if you need any info from me. 

Acer TC-780A
Intel i5-7400 cpu
bios version R02-B0 (12/6/2017)
intel HD Graphics 630

    Have you checked that the problem remains, by disabling hybrid suspension and fast startup?

    Does this model come with an offboard video card? Also, have you ever tried to press f9 to restore the uefi and then f10 to save on exiting?

    The video 630 is onboard. Does the F9 to restore the uefi settings also reset the bios version to the original version?

    Currently the motherboard firmware is called UEFI and not BIOS! F9 will only restore the UEFI to its default setting!

    Actually, UEFI is a type of BIOS that loads part of itself off the disk. The CMOS BIOS is still there, it's just minimized to run POST and then load and execute the UEFI portion.
    Have you looked at what background apps are doing? Perhaps one is keeping things active. Try a safe boot and see if sleep acts right.

    Restoring UEFI/Bios defaults resulted in no change. Will try "billsey's" suggestions. Thanks to all for taking the time to comment.

    Well...I think I might have solved the sleep problem, hopefully for good. At the CMD prompt, I typed "powercfg /requests". This command is supposed to display application and driver power requests. Seemed worth a shot. To my surprise the command displayed an active request to the printer spooler. Upon opening up the print queue, it indeed showed some system requests to print. Problem is I know I didn't make any such request and nothing was being printed. I then canceled the print requests and restarted the machine. Again the print spooler showed requests to print but no printing was occurring. Something goofy going on here. Decided to simply uninstall the printer driver and re-installed it and see what happens. Result: no more mysterious entries showing up in the print queue and the machine now goes to sleep on its own for now anyway.

    Thanks 'Yesbobber' - I had the same phenomenon, tried your approach, found an unused Norton security routine as an active request, uninstalled the app, and now my machine sleeps on its own! Your work and solution very helpful - thanks for sharing!
