Dell Latitude 3490/3590 replacement motherboard

This Dell motherboard assembly carries the Intel Core i5-8250U quad-core processor running at 1.6 GHz and uses integrated graphics. It supports dual-channel DDR4 memory and matches the LA-F116P board revision identified by part number 8M4FC. It is intended for technicians repairing Latitude 3490 or 3590 laptops that require a direct board swap.

Verify chassis and connector layout before ordering

Confirm that the target laptop is a Latitude 3490 or 3590 and that the existing board carries the same 8M4FC part number and CAL50/DAL10 markings. Check that the display cable, keyboard ribbon, battery connector and I/O port arrangement match the replacement unit exactly. Ensure the cooling assembly and mounting points align with this revision to avoid fitment issues.

Sustained thermal behaviour under integrated

The on-board i5-8250U shares its thermal budget with the integrated graphics engine, so prolonged multi-core workloads will cause the package to throttle toward its base frequency. Dual-channel DDR4 helps maintain bandwidth during extended sessions, but the single heat-pipe design typical of this chassis limits continuous performance. Expect clock speeds to settle below the maximum turbo after several minutes of heavy compute or video decode.

Questions about this item

Does the Dell 8M4FC motherboard include the Intel Core i5-8250U processor or must it be purchased separately?

The board ships with the Intel Core i5-8250U quad-core CPU already soldered on, so no separate processor purchase is required.

What distinguishes the CAL50 and DAL10 versions of this Latitude 3490/3590 motherboard?

CAL50 and DAL10 are Dell board-revision codes for the same LA-F116P design; both fit the 3490 and 3590 chassis and carry the identical i5-8250U with integrated graphics.

How does the 1.6 GHz base clock of the i5-8250U perform inside a Latitude 3490 or 3590 with dual-channel DDR4?

The 1.6 GHz base clock combined with dual-channel DDR4 delivers responsive everyday performance for office applications and multitasking within the Latitude 3490 or 3590 thermal envelope.
