Genuine Dell OEM Palmrest Ribbon Cable

This genuine Dell OEM ribbon cable connects the palmrest USH junction board to the motherboard on supported Latitude models. It is a direct replacement for part number 1V4T7. The cable is supplied new and matches the original factory specification.

Compatible Latitude Models Before Ordering

Verify that your laptop is a Latitude 7440, Latitude 7440 2-in-1 or Latitude 7450 before purchasing. This part is not compatible with other Dell series or earlier Latitude generations. Check the existing cable part number against 1V4T7, IDC40 or NBX00033H00 to confirm the correct match.
