I got tech support in chat window.  I didn't realize I have to press down on the camera to get it to pop up, and then push again to close it.  I figured it would control that itself as needed.  After I got it to pop up, I could see the tab is attached to the camera so it could be easily pulled off, but I don't think it is covering anything so I might just leave it there for now. After figuring that out, the tech was very helpful, taking over my PC and checking things, updating BIOS and drivers and doing full system check for me.   Thanks for your effort trying to help me.
Foolish question I fear, but extra cautious setting up new device.  There is an orange paper/plastic tab sticking out on top edge surface of screen, I think where web cam pops up.  Am I supposed to just pull that tab out as part of initial setup?
