Dear Mike B5655
Thank you for posting in the Microsoft Community.
If your Windows 11 Professional (23H2) computer goes to sleep despite being set to “Never Sleep” or other power settings, it may be due to some system settings, policies, or management practices related to specific hardware. Here are some ways to troubleshoot and resolve this issue.
Solution 1: Check the power plan settings
- Open the Power and Sleep settings:
Press Windows + I to open Settings.
Select System and then click Power and Battery.
- Change the power plan:
Click Other power settings.
In Power Options, view the current power plan, click Change Plan Settings, and make sure that all relevant settings (such as “Put computer to sleep”) are set to “Never”.
If you have more than one power plan, make sure that the selected plan is the one you want to use, and check each plan.
Solution 2: Check the High Performance Power settings
- Go to Power Options and make sure you have selected the High Performance power plan.
- In the High Performance settings, check all the options to make sure that the computer is not set to go to sleep.
Solution 3: Check Registry Settings
If the steps above don't work, you may need to check your registry settings:
- Press Windows + R, type regedit, and press Enter.
- Navigate to the following path:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power
- Check the following values:
PowerSettings: You may need to ensure that there are no improper settings.
CsEnabled: A value of 1 usually means enabled.
In the PowerSettings branch under Power, there are several settings that correspond to different sleep and power saving features.
Be sure to make the appropriate changes if needed.
Solution 4: Check Group Policy Settings
- Open the Local Group Policy Editor:
Press Windows + R, type gpedit.msc, and press Enter. 2. Navigate to Power Management Settings.
- Navigate to Power Management Settings:
- Computer Configuration > Administrative Templates > System > Power Management
- Check the relevant policies:
Check to see if there are any policies that may affect the sleep settings, such as the “Computer Sleep” setting, and make sure it is not enabled.
Solution 5: Run the Power Troubleshooter
- Run Power Troubleshooting:
Press Windows + I to open Settings and select System > Troubleshooting > Other Troubleshooting Tools.
Find Power and click Run.
This will help identify and fix any issues that may be affecting your power settings.
Solution 6: Check scheduled tasks
Sometimes scheduled tasks may affect your computer's sleep settings:
- Open the Task Scheduler program:
Press Windows + R, type taskschd.msc, and press Enter.
- Browse through all the tasks and check if any of them are set to prevent your computer from going to sleep at a specific time.
By doing the above, you should be able to find out what is causing your computer not to go to sleep as expected and fix it. If the problem persists after multiple attempts, you may want to consider contacting Microsoft Support for professional help. I hope this information has been helpful to you. If you have any other questions, please feel free to let us know
