Look on your keyboard for a key with an F on it and and a square around it. I use a bluetooth keyboard when I have my laptop docked which has this "Function" key. If you have it enabled it converts Pause to scroll lock and the various function keys to various hotkey commands such as search, home etc... I have to hit mine once to pause keyclone which turns my F1-F12 into something unusable. You also may have a FN key somewhere that you can hold like you hold >shift< to capatilize letters. Check that and make sure it's not locked down or stuck. >shrug< it happens.
