Using a plastic opener pry the top case palmrest assembly up and separate it from the bottom case.
Lift up the top case to access the cables. You will find the keyboard cable and the touchpad cable connected to the logic board.
Befor you pull the cable out, it’s necessary to unlock the connector.
Lift up the locking tab so it opens up at a 90 degree angle (red arrow).
Now, when the cable is released, you can pull it out.
On the other side of the top case you can access the touchpad. The keyboard is riveted to the top case and cannot be easily removed.
