Direct Replacement for Latitude 5400

This genuine Dell motherboard fits the Latitude 5400 chassis and ships with the Intel Core i5-8365U already soldered. The quad-core processor runs at 1.6 GHz base with Turbo Boost up to 4.1 GHz. Integrated Intel UHD Graphics 620 handles everyday business workloads. It is sold new for technicians and owners repairing a failed board.

Upgrade from a Slower CPU or Damaged Board

The jump is worth it when the original system uses a dual-core processor or when the existing motherboard has a damaged power circuit, dead USB ports or a cracked PCB. Moving to this quad-core part adds four extra threads and higher turbo frequency without changing the cooling assembly. Buyers who need more than 32 GB of memory or discrete graphics cannot use this board.

Straightforward Swap for Experienced Techs

Installation follows the standard Latitude 5400 teardown: remove the bottom cover, disconnect the battery, unplug the fan, display and I/O cables, then swap the board. Common pitfalls include forgetting to transfer the Wi-Fi module, misaligning the M.2 SSD screws or skipping the BIOS update that enables full DDR4 32 GB support. Thermal paste must be reapplied to the CPU die and PCH.

Questions about this item

Will this motherboard fit inside the standard Dell Latitude 5400 chassis without modification?

Yes, this board carries the 5T75M part number and is built specifically for the Dell Latitude 5400, so it aligns with the original mounting points and I/O cut-outs.

What is the correct order for seating the CPU cooler and reconnecting the fan header during installation?

Apply thermal paste to the i5-8365U die, lower the heatsink evenly, secure the screws in a cross pattern, then plug the fan cable into the motherboard header before closing the case.

Which memory modules and storage drives can be used as direct replacements later?

Dual-channel DDR4 SO-DIMMs up to 32 GB total, plus M.2 NVMe or SATA SSDs, are supported; the Wi-Fi slot also accepts a compatible M.2 wireless card.
