Facepalm: In a totally unexpected turn of events, a Windows 10 update has broken one of the OS’s major features. On this occasion, the bug is affecting some machines' Sleep Mode, with cases of computers repeatedly waking up for no reason, or the low power state not working at all. But there is a temporary fix.
Windows 10 Sleep Timeout
Windows 10 is simply not able to enter sleep mode. Whenever I try, the monitor shuts off, but the computer power does not. When I move the mouse, the log-in screen appears (as it would when your computer comes out of sleep). I looked at Windows. Here are a few quick and convenient fixes that will get your Windows 10 sleep option among the power options in Windows 10. Step to Resolve Windows 10 Sleep Option Missing The sleep option is a part of the Windows operating system and if it is no longer visible, then this must be system glitch and can be fixed via the Control Panel or Local.
Solution 1: Change Sleep Mode Settings. If the Sleep Mode is set to Never, then the computer is not going to sleep in Windows 10. If it is set to never, then whatever happens Window 10 won’t sleep. To change the Sleep Mode settings, follow the steps given below: Type Power & sleep settings in the Windows search bar and then select the top result. How to Add or Remove Sleep from Power menu in Windows 10 Sleep uses very little power, your PC starts up faster, and you’re instantly back to where you left off. You don’t have to worry that you'll lose your work because of your battery draining because Windows automatically saves all your work and turns off the PC if the battery is too low.
Windows Latest reports that the issue first appeared with the Windows May 2020 update, which introduced a slew of glitches to many PCs. Windows 10 KB4568831 fixed the borked Sleep Mode, but the problem has returned for some users who’ve installed the September 2020 optional update.
“When I close the lid, press the power button, or select Sleep in the power menu or the win-x menu, instead of sleeping, the screen simply turns off, and my laptop does not go to sleep even after leaving it alone all night,” one person wrote on Microsoft’s forum.
Sleep Mode: annoying when it doesn't work
Users discovered this is the fault of a Windows Update process called “MoUSO Core Worker Process.” It’s causing unwanted wakeups on PCs that have applied Windows 10 version 2004 and have an optional update pending for installation.
If your Sleep Mode is no longer working, the issue can be fixed by going into Windows Updates Settings and preventing the update service from running at odd hours. It’s then a matter of simply rebooting your PC and trying Sleep Mode again.
If that doesn’t work, Windows Latest recommends trying the following steps:
1. Open Windows Search.
2. Search for ‘Services.msc’.
3. In the Services window, look for ‘Windows Update’ service.
4. Click on Windows Update and select ‘Stop.’
5. Click on the same entry again and select ‘Start’ and then select ‘Restart.’
6. Go to Windows Update and click on Check for updates. Install the pending updates and reboot your device.
This is only a temporary solution, but it should stop MoUsoCoreWorker.exe from preventing Sleep Mode. There's no word yet on whether Microsoft is working on a fix.
