Genuine Dell OEM palmrest USH ribbon cable

This genuine Dell OEM ribbon cable connects the palmrest junction board to the motherboard. It carries part number GKD0H and alternate references ARCHES15_USH_FFC and 450.0SN0C.0001. The cable is supplied new and matches the component shown in the product images.

Check laptop model before ordering

Verify that the service tag or chassis label reads Latitude 5540, Latitude 5550, Precision 3580 or Precision 3590. This part fits only those four models; other Dell 15-inch laptops use a different palmrest flex cable. Confirm the existing cable routing and connector orientation before disassembly.

Thermals noise and power in normal use

As a passive flex circuit the cable draws no power and generates no heat or audible noise. It simply carries the USH signal between the palmrest board and the motherboard. Normal operation produces no thermal or acoustic impact on the system.
