Genuine Dell OEM Ribbon Cable

This is a genuine Dell OEM ribbon cable designed for Precision 3520, Precision 3530, Latitude 5580, Latitude 5590 and Latitude 5591 laptops. It connects the palmrest junction board to the motherboard. The part matches CDM80 and NBX00023U00 references.

Reliable Signal Transfer

The cable maintains consistent electrical continuity between the palmrest assembly and the mainboard during daily operation. It supports the junction board functions without signal degradation over the laptop's service life. Builders who need a different length or pin layout cannot use this part.

The ribbon cable adds no active heat or noise to the system because it carries only low-voltage signals. It draws negligible power and requires no cooling consideration. Installers without the correct disassembly tools or service manual should not attempt the repair.

Questions about this item

Will the ribbon cable generate any heat or noise when the Precision 3520 runs all day?

The cable is a passive component with no moving parts, so it produces no noise or measurable heat during continuous operation.

What must already be present in the Latitude 5580 for this cable to connect the palmrest junction board to the motherboard?

The laptop needs its original palmrest junction board and motherboard connectors intact; the cable simply bridges those two existing components.

Can this cable be used if I keep the older CDM80 part number in my Precision 3530?

Yes, CDM80 is listed as an alternate part number, so the cable is a direct replacement for that earlier revision.
