Having trouble with your Windows 10 monitor not sleeping? Here’s a quick fix guide.

Unplug Peripheral and USB Devices

Start by disconnecting all peripheral devices such as external hard drives, printers, gamepads, smartphones, and USB flash drives from your computer. Unplug each device from the USB port to ensure they are completely disconnected.

Next, check if your computer monitor can sleep properly without these devices connected. If the monitor is able to enter sleep mode without any issues, one of the disconnected devices may be causing the problem. You can then try connecting each device back one at a time and observe if the issue reoccurs. This will help you identify the specific device causing the conflict.

If you find that a particular device is causing the monitor to stay awake, it may be necessary to update its drivers or software. Visit the manufacturer’s website for the device and download the latest drivers or software updates available. Installing these updates can resolve compatibility issues and allow the monitor to sleep properly.

In some cases, the issue may not be with a specific device, but rather with the USB ports themselves. To rule out this possibility, try plugging the disconnected devices into different USB ports on your computer. If the monitor continues to have trouble sleeping with certain USB ports, it may indicate a hardware problem with those ports. In such cases, you may need to consult a computer technician or contact the manufacturer for further assistance.

By unplugging peripheral and USB devices, you can effectively troubleshoot and resolve the issue of your Windows 10 monitor not sleeping.
