All versions of Windows come with a useful function calledSleep mode.
This mode brings your system to an idle state and conserves the systems battery and resources.
But sadly, for some users, the Sleep mode feature has stopped working on their Windows 11 PC.
According to them, their system doesnt enter Sleep mode when they keep it idle for some time.
They also mentioned that the Sleep mode stopped working after installing a system update.
In this in-depth fixes guide, weve shared somepossible workaroundsto fix the Sleep mode not working issue.
Why Is the Sleep Mode Not Working in Windows 11?
Reboot Your PC
You might have already tried this solution several times after the occurrence of this issue.
Restarting the PC will refresh the entire PC, including the data and apps.
Once your PC has been rebooted, leave it idle to check whether the Sleep mode works.
This isnt an assumption, but many users have found it.
For most users, it was their mouse causing this issue.
If unplugging the external unit doesnt eliminate the issue, you’re able to tryswitching the USB ports.
To check whether thats the case, we recommend youclose all the unnecessary programsrunning in the background.
For example, in our case, its showing this process, which is created by the Spotify app.
This will initiate the originated program on your PC, and youll be able to easily figure it out.
4.Once youve identified the program, openTask Managerusing theCtrl + Shift + Escshortcut and search for it.
5.Lastly, right-choose the program in theTask Managerand selectEnd taskfrom the right-click menu.
Do the same with other tasks that are causing the Sleep mode not working issue on your PC.
2.Once theSettings appis opened, move to thePower & batterysection and expand theScreen and sleepsection.
3.Lastly, in theScreen and sleepsection, double-check each option has a timer assigned to it.
If not, then assign a timer to each option.
Doing so will enable Sleep mode on your Windows 11 PC in seconds.
This is because viruses and malware make incorrect modifications to the systems parameters and disrupt its operation.
Due to this, we suggest youcheck your Windows PC for infectionsby running a quick virus scan.
2.Now, click onVirus & threat protectionunder theBest matchsection to launch the Malware Removal tool.
3.Then, click theQuick scanbutton in theCurrent threatssection to start the quick virus and malware scan.

It could be the same in your case.

3.Then, hit theChange advanced power settingsoption onChange parameters for the plan: Balancedwindow.

After disabling the Hybrid mode on your Windows PC, check whether the Sleep mode is now working properly.
When you keep both functions switched on at the same time, none of the features function properly.
So, if youve enabled the Screen Saver option on your Windows 11 PC, we suggest youdisable it.
2.Next, click onLock screenon thePersonalizationwindow and then punch theScreen saveroption.
3.Once theScreen Saver Settingsprompt is opened, snag the(None)option from theScreen Saverdropdown.
After disabling the Screen Saver option in your Windows 11 PC, check whether Sleep mode is working properly.

Once youve disabled wake timers on your system, it shouldnt wake up randomly at different intervals.
Deactivate Fast Startup
While troubleshooting this issue, we found that the Fast startup can also cause this issue.
This is because Fast startup sometimes mistakenly closes Windows programs and services that help the system work properly.
It could be the same with the service that helps Sleep mode function correctly.
To check whether thats the same, we suggest youdeactivate Fast startupon your system.
2.Next, click onPower Optionsand then choose theChoose what the power buttons dooption from the left sidebar.
3.Then, click onChange prefs that are currently unavailableat the top of theShutdown settingswindow.
4.Finally, uncheck theTurn on fast startup (recommended)box to deactivate Fast startup on your Windows PC.
If disabling it fixes the issue, then we suggest keeping it disabled to avoid issues.

So, we also suggest the same to you.
3.Right-tap on theUSB Root Hub (3.0)driver under the same section and selectPropertiesfrom the right-click menu.
Microsoft regularly releases new updates to fix the issues with the system drivers.
It could be possible that they have already released updates for the systems display drivers to fix these issues.
Therefore, we suggest youcheck for new display driver updates and install themto eliminate the bugs with it.
3.Select theUpdate driveroption from the right-click menu and select theSearch automatically for driverstile.
Itll now start searching for new updates for the selected display driver and install them automatically.
To check whether its true, we suggest you revert all your power plan configurations to default.
