Use your fingernail or the edge of a plastic opening tool to flip up the retaining flap on LED indicator ZIF connector.

Be sure you are prying up on the hinged retaining flap, not the socket itself.

After flipping up the locking tab on the socket, use your fingers or a pair of tweezers to gently pull the cable straight out of its socket.

If necessary, transfer the power board ribbon cable to your new power board.
