How to Enable the FN Keys on Your ThinkPad

The ThinkPad has FN key functionality built into the system. You can use the FN keys at the top of the keyboard by simply holding down the blue lettered FN key on the lower left hand side of the keyboard. Once it has been depressed, any of the function keys can then be pushed to enable dual monitors, backlighting of the screen or other options available on your particular model. You can also enable and lock the FN key, in order to use the right side of the keyboard as a 10-key touchpad.
