Genuine Dell Precision M2300 LCD Back Cover

This new Dell Precision M2300 LCD back cover replaces a cracked or damaged lid on a 14.1 inch notebook. The assembly ships with hinges, wireless antenna cables and the LCD latch already fitted. It matches the original Dell part number TN178 for direct compatibility.

Who this fits and who it does not

Precision M2300 owners needing a complete top lid assembly will find every required component in one package. Builders working on other Dell models or different screen sizes cannot use this cover. Anyone who also requires the front bezel must source that part separately.

Dell part number TN178 confirms fit

The TN178 part number is the single identifier that guarantees this cover matches the Precision M2300 chassis. Verify that number on your existing lid before ordering. No other specification determines compatibility.

Questions about this item

How do I install the Dell Precision M2300 LCD back cover TN178, and which step is often missed?

Remove the old lid, transfer the hinges, antenna cables and latch from the new assembly TN178, then reconnect the antenna cables before snapping the bezel back on — the antenna routing is the step most installers forget.

What parts of the TN178 assembly will need replacement later?

The left and right hinges and the wireless antenna cables are the moving or flexing components that wear first; the plastic lid itself rarely fails unless cracked.

What limit appears first when the TN178 lid is opened and closed repeatedly?

Hinge torque fatigue shows up before the plastic cracks, making the lid feel loose or causing it to drift shut under its own weight.
