Flip up the locking flap of the ZIF connector holding the keyboard cable on the motherboard.

Pull the keyboard ribbon cable out from the connector on the motherboard.

The ribbon should detach from the palm-rest not the underside of the keyboard.

Remove the keyboard from the laptop.

While replacing the keyboard, you will not need the Jimmy. Just gently press down around the edges of the new keyboard after plugging the ribbon cable in. You will hear it click back into place as the clips engage.
