After removing the bottom plate, you will have visibility of the logic board. Using a plastic opening tool, lift the small black latch holding the ribbon cable. Slide the ribbon cable loose from the logic board.
Next, using pointed nose tweezers, remove the 4-wire white connector from the logic board by wiggle back and forth while lifting until the connector is disconnected from the board.
Metal pointed nose tweezers may cause damage if used improperly.
