It's a Vaio Sony. My cat laid on it and now the keyboard won't type a thing, not even numbers. When you try to type a letter it makes a clicking sound. Help!

I know this sounds stupid, but have you tried switching the computer off and on, and maybe unplugging the keyboard and replugging it?
No offense if you already tried those, but trying to cover some bases.

Yet again I see proof of what I suspected- Cats are evil and are out to get us.

I tried everything, but I couldn't unlock the keyboard, so I did a system restore to last week and now it is fine... thanks

Owies a system restore. Hope you didn't lose anything.
