I am no longer able to FN:F4 switch between my built in screen and an external monitor plugged into the DisplayPort.  In fact, seems that my FN functionality has ended altogether because no other FN key combos seem to do anything anymore (screen brightness, etc).  I have the OS set up to update automatically, and it has done several updates recently.  Thanks for any help!
