    Windows 8.1 does not go to sleep / standby automatically


    Hello,
    I recently did a clean install of Windows 8.1 Pro x64. Before doing the clean install, all hardware being identical, my Windows 8 was ran smoothly and went to sleep fine automatically after 8 minutes, and 20 minutes later into hibernation.

    Now, after the clean install, although I believe I have installed and set up everything as before, the computer does not reach standby automatically anymore.
    I do not seem to be able to figure out why this is, or how my configuration is different than before. I do not mean to claim that it's Win 8.1's fault (I hope it isn't, because otherwise it would mean that the solution is out of my hands), but it is much more likely that during the lengthy clean install, program installation and configuration process some things have ended up being set up differently than before.

    I'd like to figure out how to approach the solution-finding process in a systematic manner as obviously there are many possible culprits that I would like to eliminate one by one. For example, you can find many single tips on the web on this subject, but we would rather need a clear to-do list of what to check. E.g., how can the event logs be used to find the error?

    Therefore, I would very much appreciate your help in troubleshooting this step-by-step. I believe many users must have these problems so such a systematic procedure would be to the benefit of all.

    Hello Steve,

    Check using the tutorial below to see if there may be a power availability request that may be preventing your PC from automatically entering standby mode, and post back with your results.

    Power Availability Requests - Manage in Windows

    Hope this helps for now,

    Steve, check the usual suspects, Device manager-Power management in properties, Windows media in advanced power settings. BUT if you run out of ideas and places to look:

    Windows 8.1 refuses to sleep

    Rockhound and I found a bug, which I wondering if it was fixed by the Win8.1 updates. Check the last two pages top see if this helps. I hope it doesn't...

    It is the homegroup in my case too, as in yours. It now works with homegroups disabled. At first attempt, I could not get it to work by switching homegroups on again, but will try harder. In my case, there is hardly anything to unshare as the computer in question had a clean install and no shares added. The other computers also need to have folders unshared of course, but it already fails on my main computer (i.e. the idle-to-sleep functionality is lost) before they join the workgroup.

    Damn. It's a real bug then and is still there with the official release. Like you surmise Steve, it is not just the one computer but all the computers on the old HOMEGROUP network, turned on or not.

    Let me see if I can convince Brink for me to do a tutorial. In the meantime:

    1. Have all computers on the network leave the homegroup.
    2. Unshare all of the flies/folders on the computer. This can be sped up by selecting multiple folders at once.
    3. Create a new HOMEGROUP on the main computer with a new password. Share the folders you want to.
    4. Have all the other computers join that HOMEGROUP and share what files/folders you want to have shared. ALL THE COMPUTERS HAVE TO BE ON AND RUNNING!

    I appreciate your efforts, however even though I leave the homegroup on my two computers (main one Win 8.1, second one Win 7), unshare everything (computer management only shows IPC$ as the only share after I am done, and of which I cannot get rid of), then start a new homegroup on the main computer, change the password to something easy, let the 2nd computer join the homegroup by typing that password, afterwards, the main computer will not sleep again by itself. I have tried this several times in vain now.

    Maybe the difference to you is that I have a Synology NAS in my LAN? It's not part of the homegroup, but it has also shares. However, unsharing all there is a bit messy to be honest and if this is the only way to solve the issue then I would rather live without the homegroup (or ipv6, if there is a choice?) and wait until Microsoft issues a patch. Shame on them they go 1 step forward and 2 backwards with their 8.1 release.

    UPDATE: I have had a slight improvement by allowing the main computer to sleep when it is sharing media (under energy options). I did not think this should be relevant as the main computer has never been actively sharing content at any time during my tests (for example like streaming a movie, or being browsed by the other computer). Yet, I could live with that setting if it resolved the issue at hand.

    Now, it can go to sleep now and then with this option turned on, but I have observed several times that it then suddenly wakes up again while in standby. Hence, this is not a satisfying solution for me.

    Steve, now you have to go through this ENTIRE thread and eliminate all the other causes that can prevent or wake up your computer. This is a multi-step process and many things can affect it!

    for instance, go to device manager, right click of the network adapter properties, and turn off allow this device to wake computer under power management.

    At least you are making progress!

    Steve06, have you checked Brink's suggestion about using the powercfg /requests command to see what might be Keeping it awake. It can be very useful in pointing you in the right direction.

    Last year, I found out my Smart TV was keeping my system awake and tracked it down using the IP address shown in the message. Could you run the command, then right click the command window and select Mark, then right click (or enter) and then paste into you post.

    @Saltgrass: Just checked powercfg /requests and it says "none" in each of the 5 categories.

    @johnpombrio :

    Will do and report back to the benefit of all. However, instead of relying on a "sledgehammer" approach and disabling possibly more features than necessary, I would like to arrive at just the right the set of settings that means the least changes to the default settings of the operating system - just deviate from the out-of-the-box default that are strictly required for us to achieve idle-to-sleep peace of mind.



    You who got it working and have altered many settings, can't you just work your way backwards and take individual settings off to find out until when the status quo holds?

    UPDATE: I just unchecked that item in my ethernet adapter's energy settings, however am no step further. To be honest, I've been testing many of these things suggested on the web, but the only thing that gave me peace was disabling the homegroup. When homegroup is disabled, I can leave all the other default settings as they are.

    Steve, as Rockhound and I have found, this is a bitch of a problem. It took me days of working on it to get everyone to sleep and stay that way. Rockhound was also frustrated.
    Since HOMEGROUP defaults to Media sharing (which will wake your computer just because it is enabled), you will have to go around and disable it in both desktop advanced power settings and the Start Menu PC settings on all the other machines too. Note that you can still run and share your media, it just will not automatically wake up your computer to do so.
