On my HP G72 laptop, all of the Function keys are by default mapped to 
common monitor functions, e.g. screen darken/brighten, sound 
softer/louder, fast forward, fast backward, pause, start, etc.  In order 
to access the legacy meaning of function keys, there is an extra Fn key 
(lower right on my machine)that must be depressed simultaneously with a 
numbered function key.  Look for such an Fn key.
