Use the plastic opening tool to lift the locking pad on the trackpad cable connector to the unlocked position.

Use tweezers or your fingers to gently pull the cable out of its socket.

If the cable has a pull tab, use it to grip the cable. You may damage the cable by gripping it directly.

To reconnect, make sure the locking flap is flipped up and gently reinsert the cable. Then, flip the locking flap down to secure the cable. The cable should slide into the socket with little to no force. If you're having trouble, remove it, check that the flap is fully unlocked, and try again.
