This is because some of the characters type twice, and some just don't work. I.E. the m button works like the enter key sometimes, and sometimes I can't turn caps lock off, once because it was controlled by pushing c, and v at once.
I'm not worried about saving anything on it, but can't figure out how to reinstall windows onto it, I have my product key and everything, but the laptop doesn't have a cd drive.
I tried plugging a good keyboard in to type in my password, but it had the same problem, either because some software malfunction, or because interference from the built in keyboard.
