When I ran the troubleshooter, it automatically fixed the issue, as shown below. When you select the Power option, you will see a link to Run the Troubleshooter. I scrolled down and selected the Power option. Next, I typed Troubleshooting in the Windows search box and selected Troubleshoot settings. I changed the time from 5 minutes to 1 because I didn’t want to wait full 5 minutes during my testing. So far I have only verified that things are configured properly and my display was still not turning off at the specified time.
I also looked at some other settings, including the Turn off display after setting in the Display section, which was configured for 5 minutes, as I expected. This allows Windows 10 to wake from sleep on timed events. I verified that under Sleep, the Allow wake timers setting was set to Enable. I then clicked the link Change advanced power settings.
I don’t put my computer to sleep so I verified that Turn off the display setting was configured to 5 minutes, which is what I wanted and Put the computer to sleep setting was set to Never. I verified that the recommended Balanced plan, which balances performance with energy consumption, was selected. First, I went to Control Panel\Hardware and Sound\Power Options.
