Genuine Dell Precision M2400 Lid Assembly

This genuine Dell OEM lid assembly fits the Precision M2400 notebook with a 14.1 inch WXGA LED screen. It includes the LCD back cover plastic, left and right hinges, and wireless antenna cables. The part number is C139J and it matches systems using the 1280 x 800 resolution panel.

Repairers replacing a damaged lid on a WXGA LED

Technicians restoring a Precision M2400 with the WXGA LED display will find the correct hinge brackets and antenna routing here. Buyers whose M2400 uses a different screen resolution or backlight type should look at something else because this cover is not compatible with those variants.

Straightforward swap for experienced laptop

Installation requires disassembling the display panel, transferring the LCD and bezel, and reconnecting the antenna cables. What usually goes wrong is ordering the wrong back cover for the M2400, as multiple versions exist; verify the C139J part number before starting.

Questions about this item

Does the C139J lid assembly fit a Precision M2400 that currently has a 1280 x 800 WXGA LED screen?

Yes, the C139J is made for Precision M2400 models with a 1280 x 800 WXGA LED panel; it will not fit CCFL or higher-resolution variants.

Will the existing wireless antenna cables from an older Precision M4400 connect to the antenna leads on this C139J cover?

The assembly includes its own antenna cables routed for the M2400 chassis; reusing M4400 cables is not recommended because routing and connector length differ.

After installing the C139J lid, how can I confirm the hinges and latch are aligned correctly?

Open and close the lid through its full travel — movement should be smooth with even resistance, the latch must engage audibly at the centre, and the display should stay at any angle without creaking.
