Be very careful not to scrape off or damage any surface mounted components during this step.

Use a spudger to pry up and disconnect both Thunderbolt 4 cable press connectors from the logic board.

To reconnect press connectors, carefully align and press down on one side until it clicks into place, then repeat on the other side. Don't press down in the middle. If the connector is misaligned, the pins can bend and cause permanent damage.
