How to fix
Screen won’t turn off after specified time
on Windows

Hello. My display won't turn off after a certain time. Troubleshooting gives no results, and I don't know how to solve this. It started a few days ago when I think updates got installed overnight. I turned the computer on, and this happened. My computer runs pretty much all the time, but I want my display turned off and cannot achieve that now. Can you help?

The screen won't turn off after a specified time on Windows when the issues with Sleep Mode occur. This sleep time is essential for the life of the device because it gives the computer time to rest and save power while in idle mode. This is merely the feature that is created to preserve the life of a battery so energy is not wasted. 

When the screen is not turning off, the computer works fully, and the battery gets easily drained. It happens a lot faster than in the sleep mode. You can do that manually, but the automatic sleep mode entering should always work, so when it doesn't, you need to be concerned, as many users are.[ref en-1]
