Screen lock without taking settings


If I do not use USB connected devices my screen lock without reason. During this screen lock I do not have to login but just shake the mouse or press key in few minutes of inactivity. I have changed to setting activated to over 60 mins and still issue. I changed on all settings of AC power, battery and low battery.

Do you have settings here?

It shows this

I’m not sure what you are getting at? You want the screen to lock and it doesn’t?
