Windows won't sleep.

I was battling this for quite a while. None of the prescribed fixes that I found anywhere resolved the issue, so I gave up and just started manually putting my computer to Sleep. Even upgrading from Windows 10 to Windows 11 didn't fix the issue. Then, just yesterday, I finally discovered that the Lock Screen Slideshow disables Sleep mode. I switched my Lock Screen settings from Slideshow to just a single picture, and voila! Problem solved.

Hello RW 8675309,

Welcome to Microsoft Community.

Looks like you're experiencing a computer that won't go to hibernation when you press the sleep button. It's very annoying. I will do my best to help you. Here are some of my suggestions:

1. Run Windows Troubleshoot. Go to System > Trouble > Other troubleshooters. Run the Power troubleshooter and follow on-screen direction.
2. Handle applications, devices which can cause the problem. Type cmd in Windows Start Search box > Right click on cmd > Run As Administrator > Type following once per line& Enter:

    powercfg /waketimers
    powercfg /requests
   
    powercfg /devicequery wake_armed
   

It will show the list of all applications and devices which can possibly wake up your computer. To stop your PC from waking up, simply find those apps and change their configuration or remove them from your PC. Then, reboot your computer.

You can visit [powercfg-command-line-options](https://learn.microsoft.com/en-us/windows-hardware/design/device-experiences/powercfg-command-line-options "learn.microsoft.com") for reference.

3. Disable Fast Startup. Type Power in Windows Start Search box > Click Power & Sleep > Click Additional Power Settings > Click Choose what the power buttons do > Click Change settings that are currently unavailable > Scroll down to Shutdown settings and uncheck Turn on fast startup > Click Save changes.
4. If you have several peripheral devices connected to your computer, such as a Bluetooth headset, Bluetooth keyboard, Bluetooth mouse. Turn off Bluetooth first, disconnect these devices, and then try going to sleep mode. Also check your wired devices and game controller.
5. Go to Device manager. Check your peripheral devices, uncheck possible device's "Allow this device to wake the computer". Also check your wired devices and game controller.
6. Perform a hard boot (Press and hold the Power button on the computer to turn off). Then reinstall the Intel graphics driver.
7. Turn off away mode by editing registry. Press win+R, enter and run "regedit" to open the registry Find this value:

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Power 
   

   Find this value on the right:

    AwayModeEnabled 
   

   Change the value to 0 . Disclaimer: Generally, modifying registry subkeys or work group is intended for advanced users, administrators, and IT Professionals. It can help fix some problems, however, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For further protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, clickHow to back up and restore the registry in Windows - Microsoft Supportto view the article.

Hope this can solve your problem. If not, please feel free to provide me with more details, such as screenshots and error messages. I will do my best to help you.

Thank you for your patience and cooperation! I look forward to hearing from you.

Best Regards,

Liam - MSFT

I'm using Windows 10 and Outlook for my mails. Recently with new windows update for some reason my laptop stopped going to sleep mode. I checked the power configuration and everything was okay there. Nothing changed. So i was doing research and found this article. When i ran the command "powercfg /requests" i found that Outlook was the one which was creating problems in the laptop going to sleep. So i closed the outlook completely and then tried the Sleep again and it worked.

I have encountered the same problem. After researching with powercfg /energy, I found not being able to go to Sleep mode was caused by my Outlook(New)

Like you, I found that in order to go to Sleep mode, I have to close my Outlook(New).

The problem occurs on my HP Laptop but not on my Gateway desktop.

I am using MS Office 2021 Professional and Windows 10. I also use the Outlook that comes with Office. The Office version is not affected, only the Outlook(New).

My problem seems to have occurred following running of the app Privazer but can't be sure. It is not related to a recent update to Windows or a screen saver.

Having to close Outlook(New) to Sleep is not acceptable.

Did you find a solution?

I have the same issue, I changed the settings and still having the same issue. Damn computer won't go to sleep not even Shutdown, it will immediately reboot. I have to manually shut it off. I have done everything and nothing. I freaking hate windows ready to switch to Apple completely.
