Have checked there are no active wake timers Turned off wake via Ethernet and all drivers/BIOS seem up to date. Any suggestion as to why this is happening and is this a known bug requiring a patch? Also via powercfg no application are preventing sleep

I too had a similar issue. I'm posting because this thread is one of the top results Google gives for Windows 10 sleep problems.

The solution that worked for two computers I had that were not sleeping was as follows:

  • Run an admin command prompt
  • powercfg -requests
    • This command lists all processes or services currently running that are preventing the computer from sleeping. The list is helpfully broken down by categories. One of my affected computers had sleep blocked by the IncrediBuild component of Visual Studio, the other by a different TSR program.

    I tried every suggested option noted in this discussion all to no avail.  I use a wireless mouse and thought maybe it was the batteries.  Changed them, nope.  As a last idea I changed out the wireless mouse for a wired one, bingo!  I can't explain it other than the wireless mouse had gone bad and was giving off a bad signal.  anyhooo maybe give that a try.

    There is a bug with the Twitch Desktop App that will cause this to happen.  If you are running that, try closing it.

    In general, the command powercfg /requests will tell you what's preventing your system from sleeping.

    Many thanks, Zutroy - disabling Cortana completely now allows my PC to sleep soundly until I hit a key.

    How strange that - apparently - Microsoft did not foresee this problem.  When I used the Command Prompt to see what devices were waking the PC, only the keyboard was listed.  I suppose if I had disabled the mike on my cam I would have achieved the same result

    • but no one suggested that, and, as I don't use Cortana, Zutroy's tip is preferable.

    Thanks again!
