Genuine Dell OEM 14.1" Lid Assembly

This genuine Dell OEM lid assembly fits Precision M2400 laptops with WXGA LED screens. It includes the plastic back cover, left and right hinges, and wireless antenna cables. The part number M409R must match the original component. Buyers with non-WXGA displays or different back cover revisions cannot use this assembly.

Repair-Ready Hinge Integration

Pre-installed left and right hinges eliminate separate hinge sourcing and alignment during screen repairs. Wireless antenna cables route through the cover exactly as the factory designed. No thermal, noise or power characteristics apply because the assembly contains no active components.

Direct-Fit Hardware Simplifies Rebuild

Bundled lid plastic, hinges and antenna cables arrive as one matched unit, removing the need to salvage parts from a damaged cover. Builders who need a different resolution back cover or a complete display panel must source those items separately.

Questions about this item

How do I install the M409R lid assembly on my Precision M2400 and which step is most often missed?

Remove the bezel, disconnect the antenna cables from the wireless card, unbolt the old hinges from the chassis, fit the new hinges and cover, then reconnect the antenna cables before snapping the bezel back on — the step most often missed is re-routing both antenna cables through the hinge channels.

What maintenance or replacement will the M409R hinges and antenna cables need later?

The left and right hinges can stiffen or develop play after years of opening cycles; if the lid no longer stays at angle or creaks, replace the hinge pair. The wireless antenna cables rarely fail unless kinked during installation — inspect them if Wi-Fi range drops.

What is the first limit that appears under sustained daily opening and closing of the Precision M2400 lid?

The hinge torque springs fatigue first, causing the 14.1 inch WXGA LED panel (1280 x 800) to drift shut or refuse to hold position; this mechanical wear shows up before any cable or latch issue.
