Dell Latitude 7490 Motherboard with i5-8350U

This genuine Dell motherboard includes a soldered Intel Core i5-8350U processor running at 1.70GHz with turbo up to 3.60GHz. It is built specifically for the Latitude 7490 chassis and targets repair technicians or IT teams restoring enterprise laptops. Buyers needing a different CPU, a discrete GPU, or a board for another model cannot use this part.

Installation fits the original 7490 layout

The board measures 9.45 x 6.10 x 0.30 inches and weighs 0.95 lbs, matching the factory mounting points and connector positions exactly. No adapter cables or chassis modifications are required. The main risk is damaging the fragile CPU socket area or the display cable during removal; anti-static precautions and the correct torque sequence are essential.

Soldered i5-8350U decides compatibility

The processor is permanently attached, so the board only works as a direct replacement for a Latitude 7490 that originally shipped with this same CPU. It supports dual-channel DDR4 memory and NVMe storage. Systems requiring a removable processor, a different socket, or a higher core count are not compatible.

Questions about this item

How can I confirm the motherboard is working correctly after installing it in my Latitude 7490?

Power on the system and verify the BIOS recognises the integrated Intel Core i5-8350U running at 1.70 GHz with turbo up to 3.60 GHz, then check that dual-channel DDR4 memory and any NVMe SSD are detected.

What components are included with the C56HH board and what must I supply myself?

The board arrives with the Intel Core i5-8350U processor already soldered in place; you will need to provide your own DDR4 memory modules, NVMe solid-state drive, and any thermal paste or pads required for reassembly.

Which version of this motherboard matches a Latitude 7490 equipped with an i5-8350U?

Choose the C56HH part number; it is the specific revision built for the Latitude 7490 chassis and comes with the Intel Core i5-8350U quad-core processor permanently attached.
