Genuine Dell Latitude 7410 Junction Board

This genuine Dell OEM junction circuit board carries part number Y73RK and fits the Latitude 7410 and Latitude 7310 laptops. It mounts beneath the touchpad palmrest assembly and routes signals from optional fingerprint, RFID and smart-card modules to the motherboard. Buyers who need a different laptop series or a complete palmrest assembly will not find a match here.

Installation notes and common issues

Replacing this board requires disassembling the palmrest to reach the underside mounting point. Flex cables for the fingerprint reader, RFID and smart-card modules are delicate and tear easily if pulled at an angle. Misaligned connectors or a missing board screw are the usual causes of post-repair detection failures.

Compatibility checks before ordering

Confirm the laptop model is either Latitude 7410 or Latitude 7310; other models use different junction boards. Verify the existing board carries the markings FDX40 or LS-J266P to ensure the correct revision. Ensure the optional modules you intend to use — fingerprint, RFID or smart-card — are already present in the palmrest assembly.
