No problem. There are two ways to do this. Replace the kybd with the one
piece kybd which has the numeric keypad attached. Or, pop out the plastic filler
panel, And install the numeric keypad, which has a small cable that goes to the
main kybd. Either way, you must remove the white cover, flip over the
keyboard assy, and unscrew the kybd. The entire procedure should take less than 15
minutes. I have both in the keyboard and the keypad in stock.
