Press (or "pop") connectors are found at the end of a ribbon cable and have a flat, metal or plastic top—typically rectangular. These connectors are extremely common in smartphones and laptops, and connect a wide variety of small to medium-sized cables—screen, battery, board interconnect, etc.

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.

Although more rare, some larger pop-style connectors might have a built-in pull-tab for easy disconnection. Lift straight up to disconnect these.

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.

Don't press down on the middle of wider connectors until they're fully seated. If misaligned, the connector or the pins underneath can bend or break, causing permanent damage.
