Compatible Motherboard for Latitude 6430u

This genuine Dell system board is designed specifically for the Latitude 6430u laptop. It arrives with an on-board Intel Core i7-3687U processor running at 2.1 GHz, integrated Intel HD Graphics 4000, and support for DDR3 memory. The board is TAA compliant and intended as a direct replacement part.

TAA Module Requirement

The motherboard requires a separate TAA module to operate, which is not included with this unit. Buyers must transfer the existing module from the original motherboard during installation. Without that module, the system will not function, so the part assumes the user has the necessary component already available.

Suited for Component-Level Repair

This board suits technicians or experienced users performing board-level repairs on a compatible Latitude 6430u chassis. It is not appropriate for anyone lacking the TAA module, the tools for laptop disassembly, or the confidence to handle delicate motherboard swaps. Builders seeking a complete upgrade kit should look elsewhere.
