I recently started experiencing an issue with my PC, which runs Windows 10 Pro. It wakes from hibernation at seemingly random times. I have done the following to try and troubleshoot the issue:

  • Turn off wake timers
  • Disable all peripherals from waking the system
  • Unplug network cable (No Wi-Fi)
  • Try another power outlet

The computer still wakes at random times. When issuing the command 

powercfg /lastwake

I get the following:

Wake History Count - 1
Wake History [0]
    Wake Source Count - 0

I absolutely need Wake on LAN to work on the system, and it always has before. This issue only started recently.

I found that it was the "Allow Wake Timers" detailed here.

This has worked for me so far. Go to:

Control Panel\Hardware and Sound\Power Options\Edit Plan Settings

Click "Change advanced power settings"

Go to "Sleep->Allow wake timers" and change the setting to Disable.

And also from here.

Go to Task Scheduler

Find NT TASK\Microsoft\Windows\UpdateOrchestrator\Reboot

Its actually just named Reboot but you have to go inside those folders

Right Click > Properties > Conditions

Uncheck Wake the computer to run this task

The issue was caused by TeamViewer, it creates wake timers that are somehow ran(?) even though wake timers are disabled. Even shutting down TeamViewer doesn't solve the issue for me. But uninstalling TeamViewer resolved the issue.

Another approach is to see which devices are able to wake up the computer :

powercfg -devicequery wake_armed

And then, try to deactivate this device related privilege in devmgmt.msc

I think that is not possible to solve it. When some Windows updates are pending due a computer restart and the computer is in hibernate mode, it automatically turns on at the scheduled time to restart. You must restart Windows manually, but if another update requires restart and you don't restart imediatelly, when you put the computer to hibernate, at the next time scheduled to restart , the computer will turn on again. Nevertheless, it is possible to change the schedule time to a period when the computer is normally turned on.

FOUND THE PROBLEM:

edit the registry Key hkey_local_machine\software\Microsoft\Windows NT\CurrentVersion\WinLogon and modify PowerdownAfterShutdown and change it to 1

Summary: this setting prevents the computer from fully powering down upon "hibernation" if it's set to 0. Response: Who knew there would be any question? But apparently it's one more straw in the nest. If it doesn't work - I'll be back. Upvote please.

My Original post (background facts and personal peeves and observations):

Also have situation - with no teamviewer. The O.S. settings are being ignored, and no WAKE shows up in powercfg -lastwake. At first I thought that there was some intent to wake it - we all did. That is not true - it is just failing to power down. Note that this error is a prime security issue. And, it is standard operating procedure for Microsoft with its impossibly arbitrary levels of complexity, to create the situation incidentally (not accidentally.) They weren't happy with just being impossibly stupid since the browser wars - they had to double down again and again. Someone needs to go in that place and seriously reformat their drive.
