SKU CH-GJ0F-MYV4G

Genuine Dell OEM 15.6" LCD lid back cover assembly with wireless antennas and Tron LED lighting for Alienware 15 R3 FHD models

  • Genuine Dell OEM part ensures exact fit for Alienware 15 R3
  • 6 inch FHD back cover restores original laptop appearance
  • Includes two wireless antenna cables for complete connectivity
  • Integrated Tron LED lighting cables maintain factory lighting effects
  • Part number 490PN guarantees compatibility with specified Alienware models

Genuine Dell OEM Replacement Lid

This genuine Dell OEM back cover assembly fits the Alienware 15 R3 with a 15.6 inch FHD display. It replaces a damaged or worn lid using the original 490PN part number. The assembly arrives new and matches the factory specifications for that model. Buyers with a different screen resolution or another laptop series cannot use this part.

Integrated Antennas and LED Lighting

The cover includes two wireless antenna cables and the Tron LED lighting strips with their cables already routed. This integration means the repair restores both Wi-Fi reception and the signature AlienFX illumination in one step. No separate antenna or light modules are required during installation. Builders who need a plain lid without lighting or antennas will find this assembly unsuitable.

Direct Fit for Cracked or Flexing Lids

The part upgrades a cracked, scratched or excessively flexing original cover on an Alienware 15 R3 FHD unit. It is worth fitting when the existing lid no longer protects the panel or the lighting has failed. Owners of the UHD or touchscreen variants, or any other Dell model, must source a different part number.

Questions about this item

What interface does the wireless antenna use and what does it cap in practice?

The antenna cables connect to the laptop's internal Wi-Fi card via standard coaxial connectors and cap at the card's rated speed.

What physical dimensions must the laptop chassis match for this lid assembly to fit?

It fits the Alienware 15 R3 chassis with a 15.6 inch FHD display; the hinge points and screw holes align only to that model.

How is the Tron LED lighting installed and which step is often missed?

Route the LED cables through the hinge channels, plug them into the motherboard header, then secure the cover; the header connection is often missed.
