YOUR PROBLEM IS QUITE SIMPLE TO SORT OUT. FIRSTLY IT SOUNDS LIKE THE RUBBER TOUCH PAD HAS PROBABLY JUST COME AWAY FROM THE KEY. JUST GET A VERY SMALL FLAT SCREWDRIVER & UNCLIP KEY FROM KEY BOARD , IF RUBBER IS NOT UNDERNEATH KEY THEN JUST GET HOLD OD AN OLD KEYBOARD & TAKE A RUBBER TOUCHPAD FROM THAT. IF TOO BIG JUST CUT IT DOWN ,PLACE ON CENTRE OF KEY OR BASE ,THEN JUST PRESS KEY BACK ONTO KEYBOARD & VOILA.
