The good news is that you can find the setting in Windows Setting that you can open by pressing Win+I. Then, go to System > Power & sleep.
You can find a setting called Screen (When plugged in, turn off after) on the right-hand side. Make sure that a particular time is selected instead of Never.
If not, select a time according to your requirement. However, if you are using a Windows 10 laptop, you can find one more setting named after on battery.
2] Check Sleep settings
Like the screen turn-off settings, it is equally important to check the Sleep settings. Although Windows allows users to keep the PC on while turning off the screen, it may create conflict at times. Therefore, you need to disable the Sleep settings.
Windows 11: Open Settings > System > Power > Screen and Sleep settings. Make sure that it is selected as Never.
Windows 10: Press Win+I to open the Windows Settings panel and go to System > Power & sleep. Here you can find an option called Sleep (When plugged in, PC goes sleep after).

3] Check Multimedia settings
Let’s say that you are transferring a big file from your computer to an external hard drive, and it has crossed the screen turn off and sleep time if your computer goes into sleep mode. It will create interruption, and the screen won’t turn off. Therefore, open the same Power & sleep settings page and click on the Additional power setting option.
Then, click on the Change when to turn off the display option and click the Change advanced power settings. Expand the Multimedia settings > When sharing media and choose the Prevent idling to sleep option.
Click the OK button to save the change. Apart from that, you can also tweak the Video playback quality bias and the When playing video settings. These two options are visible in the same location as above.

Therefore, open the Task Manager and check which apps are running. If you find something unusual, select the app and click the End task button.
You can check the system tray as well, where Windows keeps some VPN, antivirus, etc., apps. Also, if cloud storage or any other online file synchronization app is opened in your Task Manager, it is recommended to close it.
5] Check USB devices
If USB devices keep disconnecting & reconnecting in Windows 10, there is a chance of getting this problem. Therefore, follow that tutorial to fix the issue and check if that solves your original problem or not.
Also, you can unplug all the USB devices such as external hard drive, pen drive, game controller, Wi-Fi adapter, etc., and check if the problem remains or not. If you don’t find the issue anymore, you can plug in one device at a time to find out the culprit.
6] Run Power troubleshooter
To run Power troubleshooter in Windows 11, follow these steps:
- Open Windows Settings on your computer.
- Make sure you are in the System tab.
- Click on the Troubleshoot option on the right side.
- Click the Other troubleshooters menu.
- Find the Power troubleshooter and click the Run button.
- Continue following the screen instructions.
If you are using Windows 10, follow these steps:
