Computer won't sleep? Try this.

  1. Run CMD Prompt in administrator mode. 
  2. Type: "powercfg -requests"
  3. Check and see if anything is in use. If it is, tell your system to override it using this command where 'ASUS Xonar DG Audio Device' was the driver name from the first command: 
  4. powercfg -REQUESTSOVERRIDE DRIVER "ASUS Xonar DG Audio Device" SYSTEM
  5. Now type powercfg -requestsoverride to verify your devices got added to the exception list.
  6. Make sure there's no waketimers.  powercfg -waketimers As you can see, on Windows 10 there's this default one.. even though in my power cfg they're set to off.
  7. Search Task Scheduler
  8. Navigate to Task Scheduler Library\Microsoft\Windows\UpdateOrchestrator\Reboot
    Note: Reboot is just a file, but you need to go inside all those folders
  9. Right Click Properties then click Conditions
  10. Uncheck Wake the computer to run this task
  11. Beware... Windows update might re-enable it automatically. When you type powercfg -waketimers though, it should say there are none now. 
  12. Another thing to check....
  13. Search: Local Group Policy Editor (you can launch gpedit.msc)
  14. Navigate to: Computer Configuration / Administrative Templates / Windows Components / Windows Update
  15. Double click on: Enabling Windows Update Power Management to automatically wake up the system to install scheduled updates and set it to "Disabled"
  16. powercfg /devicequery wake_armed
  17. For everything in that list that isn't your keyboard or mouse, disable it like
    powercfg /devicedisablewake "Intel(R) Dual Band Wireless AC-8260"
