How to stop wake timers

Hello,

Thank you for posting in Microsoft Community.

I will be glad to assist you with the issue you are experiencing with the computer. I understand the difficulty when things won’t work the way they should.

I suggest you to follow the below steps and check if it helps you regarding the issue to resolve.

To see a list of wake timers set on your computer, you can run the following command.

Note: this command must be run as Administrator.

• Press Windows + X keys and select Command prompt (Admin)
• Type powercfg -waketimers and hit enter.

If a specific program is causing your computer to wake, you can uninstall it or adjust the scheduled task’s settings in the Windows task scheduler.

However, if you don’t want any programs waking your computer up automatically, you can disable wake timers entirely.

To do so,

• Press Start and Type Power Options and select it.
• Click the Change plan settings link in the Power Options window.

• In the next window, click Change advanced power settings.

• Expand the Sleep section, expand the Allow wake timers
  section, and ensure that wake timers are set to
  Disabled.

• Click OK and restart the machine. Check if the same issue persists.

Hope this information helps. Keep us posted to help you better.

 

Windows wakes up with Wake Timers set to off

Dear Geethu! Really thanks for such fast reply. But!

In other words - you don't know how to get rid of wake events! Did you underastand my question? How exactly your solution is helping in getting rid of wake events?

I do not want to troubleshoot power as I said before, I want Windows not to wake up no matter what is set in Allow Wake Timers setting. I want to turn off Wake Timers for real, once and for all, and forget about them for the rest of my life.

And the question (after applying your solution) still remains: why PC is waking up if Wake Timers are disabled?

Of course your solution is not working.

 

Wake timers

Hey all, i was wondering about the wake timers in windows... my pc has been waking up in the middle of the night because of wake timers, and while i know how to disable them, i was wondering if there could be any adverse effects of doing this? The timers
seem to be set by windows itself for maintenance stuff. Im just worried that disabling them could keep my system from updating properly or doing its required maintenance. Any help is greatly appreciated, thanks.
