Power settings, interfering devices, and many other items can cause this issue. Here’s how to fix the problem.
Windows 10 will turn off the screen after a set time, allowing you to take a break without shutting down your device or putting it into Sleep mode. Also, it might keep away your information from curious eyes and save some energy if you are using a laptop without plugging it in.
If that doesn’t happen on your Windows 10 PC and the screen remains on, there might be an issue with your settings. This guide shows you what setting options you should change so that Windows turns your screen off after set time.
This is the first setting that you need to check. Here is how you can do it:
Once you have changed Screen settings, take a look at Sleep settings. While you can keep your laptop or PC turned on while the screen turns off, it might create conflicts if Sleep settings are not appropriate.
To avoid any problems, make sure the options for On battery power, PC goes to sleep and for When plugged in PC goes to sleep after are not set to Never.
A computer screen that doesn’t turn off after set time represents a power-related problem. This is why running the Power troubleshooter might fix it. Here is how you can do it:
An app could keep running without you noticing, and it prevents your device from turning off the screen or entering Sleep mode. For example, Windows 10 assistant, Cortana, might keep getting activated by certain keywords. Also, if you have opened cloud storage or any other online synchronization app is running, you should close it.
The best way to fix this is to check Task Manager:
If you are copying a large folder from your device to an external USB flash drive and your screen doesn’t turn off after the set time, you need to take a look at advanced power settings:
When your USB devices keep disconnecting and reconnecting, it will prevent Windows 10 from turning off the screen. You can fix this by unplugging all USB devices such as keyboard, mouse, external hard drive, etc. and check if this solves the problem. If this fixes it, connect your devices one at a time to find out which USB device causes the problem.
In case you can’t identify the problematic USB device, you should run the Windows 10 troubleshooter. As it might take a while to run an individual troubleshooter for keyboard, Bluetooth, or printer, you should use the Hardware and Devices troubleshooter.
Follow these steps to do so:
Note: A malfunctioning USB port might also cause this issue.
These solutions show what you can do if your computer screen doesn’t turn off after the set time. A Windows 10 update may cause it, but it can come up at any time. If you see this issue again, restart your device first, as this may be enough to fix it.
