Genuine Dell OEM Junction Board

This genuine Dell OEM junction circuit board is designed for the XPS 13 9380 laptop. It mounts beneath the touchpad palmrest assembly and provides the electrical link between the keyboard and the main system board. The part carries Dell part number FD28C and is supplied new in original condition.

Sustained Signal Integrity

Under continuous typing and trackpad use the board maintains stable signal paths without degradation. The circuit layout handles repeated keystroke data and touchpad coordinate streams across extended sessions. No active cooling is present, so thermal performance relies on the surrounding palmrest chassis.

Proprietary Palmrest Interface

The board uses a Dell-specific connector layout that matches only the XPS 13 9380 palmrest assembly. Alternate part numbers ED030 and LS-E672P refer to the same physical interface. Builders needing a different form factor or a second expansion connector cannot use this component.

Questions about this item

How much heat or noise does the FD28C junction board add when the XPS 9380 runs all day?

The FD28C is a passive circuit board with no fan or moving parts, so it generates no audible noise and only negligible heat during continuous operation.

What existing parts must I already have in my XPS 9380 for the FD28C to work?

You need the original XPS 9380 palmrest assembly, touchpad, keyboard, and motherboard; the FD28C simply plugs into the existing connectors on those components.

Will the FD28C function correctly alongside the original LS-E672P board already installed in my 9380?

The FD28C replaces the LS-E672P entirely; it is the same Dell OEM part under a different number, so it works identically with the rest of the 9380 hardware.
