Hi I set it on my mac that every 4 hours left untouched it goes to a password screen I am currentely on that. However when I try and log on only some of my keys work such as tab, and iopjklm all represent numbers. This makes me think that number lock is enabled. I've tried fn f6 I have no clear key I've turned it off an on any other suggestions. Believe I have mousekeys on aswell which is an inconvenience.
