Note: "IOT" ==> "internet Of Things". Imagine a vending machine in the corporate break-room that you can query from your office computer, to tell you which bottle of pop is the coldest? That is a "thing" with an "Internet" connection.
Does pressing the ESC key (top-left corner of your keyboard) cause an exit from that "diagnostics" mode? Or, "F3". Or "F12" ?
Maybe, it's time to recruit a teenage grand-child who has been using computers since birth?
Or, take it to a professional technician.
