Genuine Dell OEM Ribbon Cable for XPS 15 and 17

This is a genuine Dell OEM ribbon cable that connects the daughter USB IO board to the motherboard in Dell XPS 15 (L501X) and XPS 17 (L701X) laptops. It carries the part number 1139-F and is supplied new in excellent condition.

Suitable for XPS L501X and L701X board repairs

This part suits technicians or owners replacing a damaged flexible cable on the listed Dell XPS models. It is not for users whose USB failure originates from the IO board 861CJ or 45M3V itself, nor for any laptop outside the L501X and L701X series.

Connector matches Dell USB board 861CJ and 45M3V

The cable interface is keyed to the specific daughter USB IO boards carrying part numbers 861CJ and 45M3V. Verifying that your board carries one of those numbers is the single check that confirms this ribbon is the correct replacement.
