Genuine Dell Precision M4400 LCD back cover

This genuine Dell replacement part is the 15.4 inch LCD back cover assembly for Precision M4400 laptops equipped with RGB-LED backlit screens. It arrives new with left and right hinges plus wireless antenna cables already fitted. The part number P351D matches the factory specification for this specific chassis variant.

Passive chassis component with no power draw

As a structural plastic assembly this cover draws no power, generates no heat and produces no noise during operation. It simply replaces a cracked or damaged lid to restore the original rigidity and hinge alignment of the workstation. Installation requires only hand tools and does not affect system thermals or acoustics.

Bundled hinges and antennas simplify the repair

The included hinges and wireless antenna cables eliminate the need to salvage those parts from the old lid or source them separately. Missing items such as the LCD trim bezel, mount rails, latch hook and video ribbon cable must be reused or purchased elsewhere. Builders needing a complete display module will require additional components.

Questions about this item

How do I install the Dell Precision M4400 LCD back cover P351D without damaging the wireless antenna cables?

Route the antenna cables through the hinge channels before snapping the cover into place; pinching them between the hinge and the chassis is the step most installers get wrong.

Which parts of the P351D assembly will need replacement after repeated opening and closing?

The left and right hinges and the LCD latch are the moving parts that wear first; the plastic cover itself rarely fails unless cracked.

What is the first limitation that appears when the P351D cover is used continuously on an RGB-LED Precision M4400?

The hinge torque weakens over time, causing the lid to drift closed instead of holding its position at wide angles.
