Windows 8.1 Won't Sleep When Idle

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:

SkyDrive will probably show the HTML upon clicking above. Try clicking Download and then opening the file. Thank you for your help.
I originally posted this on Super User, but I haven't received any respones.

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.

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

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!

All computers that are using HOMEGROUP have to all be on the same HOMEGROUP and have to be properly configured to share something before any of the computers will auto sleep properly.

Example, I had two computers on Win 8.1 Pro (which automatically starts a HOMEGROUP when installed) that would NOT connect using my old HOMEGROUP password. I created a new HOMEGROUP password and managed to get these two computers to share files. However, there was a THIRD computer on the network (with Win 8) who had the old HOMEGROUP password. I successfully changed it to the new HOMEGROUP by leaving and rejoining using the new password. Yet I could not see any files on this last computer. I had to UNSHARE with the HOMEGROUP all of the files and folders under users. Then I shared the one folder that I wanted to share. That worked and that also FINALLY let my computer sleep!

 

Two other things. The computers do NOT have to be booted up to cause this issue. You can easily tell if this is your problem by disabling your network adapter, setting sleep for one minute and waiting 5 minutes to see what happens.

You might have same problem as I had with Windows 8.1. It was network settings related. My PC did not sleep because of LanmanServer service and one sharing setting that I had enabled. To disable LanmanServer service, you need to go to services. Just type services to RUN row and press enter. All services are opened before you. Find LanmanServer service and press right button of your mouse. Stop it and disable its automatic start and it won't start with Windows anymore. Next you need to disable that one jamming network sharing setting. Open network and sharing center by right clicking your WLAN bars. Then press "change advanced settings for sharing". Press All networks and click Disable sharing of public folders. That did it for me, the computer sleeps!
