Ever since I upgraded to the Windows 8.1 beta (and even now with the Windows 8.1 RTM), my computer will not idle to sleep. This wouldn't be that much of a problem since I almost always remember to put it to sleep before walking away. But sometimes the computer will wake on its own through a scheduled task, and then the computer will stay on until I return to it. (By the way, I'd rather not disable scheduled tasks from being able to wake the machine.)
The computer is set to sleep after 30 minutes of inactivity. I have set the Power Option "When sharing media" to "Allow the computer to sleep." I have deactivated all "wake_armed" devices so that

powercfg /devicequery wake_armed

returns

NONE

I have installed all the drivers Windows couldn't automatically detect (of which there was only my "Creative Game Port"). Finally, I have generated a report from

powercfg /energy duration 3600

Originally, it informed me of a few problems, such as the "When sharing media..." setting. As I said earlier, I have now set the "When sharing media" setting to "Allow the computer to sleep." Here is the report, which seems to suggest that I have no further serious problems:

I originally posted this on Super User, but I haven't received any respones.

For me the fix was to leave the Homegroup. Not sure why this is broken but that fixed the sleep issue across two machines.

check all of your devices in device manager and disable "Allow this device to wake..."?

xendrome, I think
powercfg /devicequery wake_armed
should reveal all devices which have that setting enabled. Either way, I've checked the usual suspects, and none of them are allowed to wake the computer.
Brando212, I upgraded from Windows 8 to 8.1 beta, which is when I first noticed this problem. But with the final version, I performed a clean install, and the problem remains. But maybe you could discover the source of your problem with
powercfg /energy duration 3600
The result of that operation is pretty insightful, although it still didn't help me.

Brando212, Windows 8.1 automatically started a Homegroup for me.  Windows 8 did not do this, so I'm guessing that's why Windows 8.1 has this problem.

I had this same problem. It ended up being my Logitech USB wireless receiver that came with my keboard/mouse combo causing it.

interesting, did it show under "powercfg /requests" for you?

 

i have logitech wireless mouse/keyboard on mine but it doesn't show up on that command

 

edit: also yeah I checked and my computer definitely isn't part of a homegroup. when i click on homegroup it asks if i want to join one. so that's not the problem for me

gonna set

powercfg /energy duration 3600

before i go to bed tonight to see if it shows any results. so far i haven't been able to find any reason why my computer won't go to sleep.

 

though GreyWolf's post makes me wonder if my problem is the same as his

I had the same problem with 8.1 (RTM) fresh install.

Its joined up to a Server 2012 Essentials server, and not part of a homegroup. However, removing the PC from the non existent home group solved the issue for me!

Thanks!
