Why is my laptop screen blank?

Episode 1477 (1:49:32)

Sam from South Williamsport, PA
Keyboard

Sam was printing up his son's graduating announcements and his cat walked across the keyboard and now the computer is blank. What happened? Leo says that there is a button on the keyboard that can turn off the screen. It's probably one of the function keys that was triggered to make the laptop look for an external screen. From the chatroom - here's an article on the subject. He can also program those buttons, so it may be a good idea to disable it.
