Touch pad. I taped an old plastic card (credit card size) to the laptop so I can flip it over to access the touch pad. This almost ensures I don't turn it on by mistake. Yes, it is easy to do... I would be typing away, concentrating on the keyboard with a peaked cap on, look up to proof read and wonder how the heck I got to... where the heck am I? It is not foolproof (go ahead). Maybe I should patent my invention?
