    Hi, I was reading a few things on this- maybe something here will give you another idea- sorry of you've already covered all this.
    Check your ethernet connection properties.

    Clearly that sleep works in safe mode is a big clue. Does it if you do a clean boot?
    Else look at drivers loaded- Autoruns can help here.
    Driver incompatibility - perhaps need to use an older driver/wait for update - but you need to identify which one.
    Scheduled tasks can be set to wake the PC. (? how do you search scheduled tasks for those that are set to do so?)
    Thanks for taking the time to reply but unfortunately I've already tried everything listed.

    I can confirm however that whilst a Safe Mode boot gets power management working again, a clean boot does not. Shutting all startup programs down, along with disabling all non MS services yields the same result - no sleep.

    I'll take a look with Autoruns and see if I can narrow things down further.

    Something that is very interesting is that whenever the PC is at the Windows Logon screen waiting for a password it will sleep just fine regardless of the mode.

    If I boot into Safe mode power management works fine, however if I boot into Safe mode with Network support it again stops working.

    I've been into BIOS and disabled the NIC to try and isolate it as a cause, but it has no effect.

    Hi, assuming that it's something to do with a driver, (perhaps a big assumption) but you've narrowed things down a lot, try to determine which drivers are active when you are in Safe Mode with Networking compared with Safe Mode. Then disable drivers selectively, and retry.

    I think this will help:
    http://www.nirsoft.net/utils/driverview.html

    So if you run that in both SMode and SMode with N, and compare, you should be able to work out the difference.
    Then disable 1 or more of the drivers running additionally in SMode with N at a time, reboot to SMode with N and retest.

    Maybe- never tried anything like that! Good luck.

    You

    Thanks - will give that a go now, then if that fails I'm going to put a new HDD in and do a clean install of W10 to see if it's there from the start or from something I've done since installing.

    By using a file compare utility and cleaning up the results I can see the attached differences between Safe Mode and Safe Mode with Networking.

    Not sure if driver differences explains why auto sleep is working from the logon screen in any mode though.

    - just depends what's actually been loaded and is active at that stage I guess.
    Certainly if you've a spare HDD then a clean install will eliminate some possible causes, and if you still have the same problem, will be easier to diagnose..

    Although I didn't get to the bottom of what was causing the issue, a clean install of Windows 10 has resolved the problem for me. If as I re-introduce my apps I find the culprit I'll update the thread but for now at least I'm happy

    Thanks- that could well help someone- quite a few are having different issues with too much or too little sleep...

    for those, who are still having sleep issues, try to check whether you are using hybrid sleep. if yes, switch to just sleep and if it works, check your event log for volmgr error. i had this issue on my Asus H97 PRO MB. it turned out, that intel rapid storage drivers prevented windows from going to sleep due to the error of loading crash dump drivers (event id 45). i rolled back to storahci drivers and don't have this problem anymore. hope it will help somebody.

    It's clearly driver related - even after a clean install, I only updated two drivers using right-click update this driver online from within driver manager and I ended up with another problem.

    The PC would sleep no problem, only this time it wouldn't wake the monitor up and required a hard shutdown / restart.

    I've rebuilt again and left all the drivers as per the initial install and it's rock solid. Seems that in my case, actually updating drivers was causing issues.
