Place a spudger or an opening tool under the connector's edge and pry straight up to disconnect it.

Make sure to pry under the edge of the connector itself, and not under the socket on the board. Otherwise, you risk permanently damaging the socket.

Work carefully: don't pry on or accidentally scrape any small, surface-mounted components on the board.

To reconnect, align the connector carefully over its socket and press down with your fingertip—first on one of the short sides, then the other—until it clicks into place. Don't try to force the connector into place. If you're having trouble, reposition it and try again.
