My laptop Toshiba Satellite C870 turns on automatically when I open it. And this seemingly happens, however when I want to write in my pin code, I cannot do so!! I press the right keys on the keyboard, but it doesn't register, like nothing appears. So I go to restart and then I can write my pin code . It is as if the automatic switch on system ,when opening the computer lid doesn't work as it should. Is there something I can do to fix that? It is rather time consuming to have to restart before I can get going.
