Genuine Alienware 15 R3 lid assembly

This Dell OEM back cover replaces the damaged lid on an Alienware 15 R3 laptop equipped with a 15.6 inch FHD panel. It restores the original structural integrity and cosmetic finish of the chassis. The part carries Dell part number FKD90 for precise identification.

Direct-fit replacement with integrated antennas

Installation follows the factory disassembly sequence; the assembly arrives with both wireless antenna cables and the Tron LED lighting cables already routed. Technicians must take care when reconnecting the fragile antenna coaxial connectors to avoid snapping the centre pins. No additional brackets or adhesives are required beyond what the original design specifies.

Maintains factory thermal and signal performance

Under sustained workloads the lid continues to serve as the antenna ground plane and LED diffuser exactly as engineered. The metal shielding and cable routing preserve Wi-Fi reception quality during extended gaming sessions. LED illumination remains consistent without overheating or colour shift over long periods.
