Use a spudger or a clean fingernail to flip up the locking flap on the two ZIF connectors securing the touchpad button board to the motherboard and touchpad.

Once the flaps are in the unlocked position, use tweezers or your fingers to gently pull the cables out of their sockets using the blue pull tabs.

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.
