Lenovo 11e E/Edge :: ThinkPad E520 - Auto Lock Mode / How To Turn It Off

Although great when you're on walkabout with your laptop, when I'm at home, laptop plugged in, I don't want my laptop to keep reverting to a login screen every few minutes.
 
I'm on a Thinkpad E520 running Windows 64 bit Professional.     Here's what I tried so far without success:
 
1)  Control Panel --> Power Options --> I set everything to "max performance" and disabled display sleep-mode timers.
 
2) Control Panel --> Lenovo - Camera-enhanced security --> I turned off camera recognition features and related timers.
 
3) Control Pannel --> Lenovo Power Manager -->  I turned off all timers.
 
Turning off options in the above control panel areas does not seem to affect the auto-protect feature.    This auto lock down feature is driving me nuts at home, the only consolation being that the fingerprint scanner makes it a little easier to get back in once the laptop goes down.    It's like some terrible screen saver you hate that can't be turned off.
 
How is this auto lockdown feature turned off?   Ideally there should be a big button available in the taskbar which you can push: on - off.   That way you can easily turn timer suites on and off with a single action.
 
But as of yet, I can't find anything in the control panel or taskbar that turns off this auto lock down feature.
