Genuine Dell Latitude 5400 System Board

This genuine Dell OEM motherboard is a direct replacement system board for the Latitude 5400 laptop. It arrives with an on-board Intel Core i7-8665U processor running at 1.9 GHz base frequency and a maximum turbo of 4.80 GHz. The board integrates discrete AMD Radeon graphics for visual output. The Dell part number is CNJCN.

Suits Latitude 5400 discrete graphics models only

This board fits Latitude 5400 units that originally shipped with discrete AMD Radeon graphics. It will not work as a replacement for Latitude 5400 systems that use integrated Intel UMA graphics. Buyers who need a board for the integrated graphics variant should look for the correct UMA part number instead.

It reuses the laptop's current memory, storage, battery and display cables. Swapping the board restores full platform function without requiring a new enclosure or peripherals.
