Dell Latitude 5591 Replacement Board

This genuine Dell OEM motherboard carries part number 31PG4 and is built specifically for the Latitude 5591 laptop. It arrives with an on-board Intel Core i5-8400U quad-core processor running at 2.5GHz. The board is intended for technicians or owners repairing a failed system board in this exact model.

Integrated Graphics Platform Constraint

This system board only supports configurations that use integrated Intel graphics. It will not fit or function in Latitude 5591 units that were originally equipped with a discrete GPU. Buyers who need a board for a discrete-graphics variant must source a different part number.

On-Board i5-8400U Decides Fit

The soldered i5-8400U CPU means the processor cannot be upgraded or swapped separately. If the target laptop requires a different CPU or a discrete graphics option, this motherboard will not meet that requirement.
