Using the tip of the spudger, flip up the small locking flap on the ZIF connector. Now you can pull the cable.

Be sure to pry up on the hinged flap, not the connector socket.

The white line on this ribbon cable marks the edge of the connection area. To reinstall, insert the cable into the connector up to this line, and then close the locking flap. If the cable doesn’t insert easily up to (or very near to) this line, it’s probably misaligned and needs to be gently removed and repositioned.
