I have my screen saver wait time set for five minutes. For those afk moments. I have On resume, disply logon screen. checked. When I click Preview it flashes on for a second or two and goes off. Power settings are set to Balanced. Turn off display in ten minutes. Put the computer to sleep: 1 hour.
The screen saver does not come on any more. I tried a reboot. Is there something I could/should look for in Windows Task Manager Processes?
