Replacement Lid for Precision M6400

This genuine Dell back cover assembly fits the 17.3-inch Precision M6400 when it is equipped with the Edge-to-Edge RGB LCD display. The part number N780K must match the original component to ensure correct alignment and connector routing.

Build Integration and Clearances

The assembly arrives with left and right hinges, hinge covers, the LCD video ribbon cable and the wireless antenna wires already installed. It replaces the entire lid section without requiring separate hinge or cable sourcing, freeing the technician from ordering multiple loose parts.

Sustained Use Behaviour

Original Dell plastics and metal hinge brackets maintain their torque and finish through repeated open and close cycles. The factory-routed cables resist fatigue from daily lid movement, preserving video signal integrity and wireless reception over the service life of the chassis.
