There are two clips that hold the ribbon cable in place. To release them push them forwards towards the keyboard. The ribbon should then slide out without resistance.
At this point you should disconnect the touchpad. The cable is on the left (highlighted orange).
To disconnect the touchpad raise the black bar. There is a clear tab with the label MB stuck on it. Use this to pull the cable from the board. Once again there should be no resistance.
