DELL Precision 7540 Motherboard Intel Core i9-9980HK 2.4GHz 2H58H

Genuine Dell OEM Motherboard for Precision 7540

This is a genuine Dell OEM system board built for the Precision 7540 mobile workstation. It arrives with the Intel Core i9-9980HK octa-core processor permanently soldered at 2.4 GHz. The part number 2H58H matches the factory service manual for exact identification. It replaces a failed or damaged board in the same chassis.

Direct Replacement for Failed Precision 7540 Boards

This board replaces the original system board inside a Dell Precision 7540 laptop when that board has failed. The jump is worth it when the existing board no longer posts, shows video faults or suffers from power-regulation damage. Swapping the board restores the workstation to its factory specification without changing the chassis, display or peripherals. No other laptop model accepts this part.

Proprietary Laptop Mainboard Limits Upgrade Options

The board uses a proprietary Dell layout and a soldered BGA processor, so the CPU cannot be upgraded or swapped for a different model. Memory slots and storage connectors follow Dell's own pin-outs rather than a desktop standard. Builders who need a socketed CPU, standard ATX mounting holes or a second graphics card cannot use this board. It serves only as a like-for-like repair part for the Precision 7540.
