Hello O-S_870 and welcome to the Microsoft Community!
Based on your feedback, you are experiencing an issue where your Windows 11 laptop keeps shutting down or restarting when idle!
This may be due to power settings or system hibernation settings. Here are some possible solutions:
- Check the power and sleep settings:
- Open Settings > System > Power & Sleep.
- Make sure the “Screen” and “Sleep” settings are set to a time that suits you.
For example, you can set “Sleep” to “Never” to prevent automatic hibernation.
- Check the advanced power settings:
- Open “Control Panel” > “Hardware and Sound” > “Power Options.
- Select the current power plan and click “Change Plan Settings”.
- Click “Change Advanced Power Settings” and in the pop-up window, expand the “Sleep” option and make sure the “After Sleep” is set to a time that suits you.
- Disable Fast Startup:
- Open “Control Panel” > “Hardware and Sound” > “Power Options”.
- Click “Select Power Button Functions” on the left side.
- Click “Change settings that are currently unavailable”, and then uncheck “Enable fast startup (recommended)”.
- Check the system device settings:
- Open “Device Manager”, find “System Devices”.
- Find “Intel® Management Engine Interface”, right-click and select “Properties”.
- In the “Power Management” tab, uncheck “Allow computer to turn off this device to save power”.
- Update the drivers:
Make sure all device drivers are up-to-date, especially graphics card and chipset drivers.
- Check system logs:
Open “Event Viewer” and check the system logs to find out the specific reasons that cause the system to shut down or reboot.
You can upload the transaction log file to me, I will help you to see what causes this problem!
I wish you all the best in this special season - may your holidays be merry and bright! Merry Christmas!
