Genuine Dell Latitude 3480 3580 Motherboard NPJPN

This genuine Dell OEM system board is built for the Latitude 3480 and 3580 laptops. It arrives with an on-board Intel Celeron 3865U processor running at 1.8 GHz. The part number NPJPN confirms exact compatibility for those two models. Builders repairing either chassis can install this board directly.

The CPU is soldered to the board, so no separate processor purchase or socket handling is required. Thermal paste and cooler mounting follow the original Dell layout for the 3480 and 3580. This integration removes the risk of bent pins or mismatched coolers during a repair. The board restores the laptop to factory specification without extra parts.

Dell OEM construction matches the original chassis mounting points and connector placement. Ports, ribbon cables and screw holes align with the 3480 and 3580 service manuals.

Questions about this item

Will the soldered Celeron 3865U ever need replacing on this NPJPN board?

The Celeron 3865U is soldered directly to the motherboard, so it cannot be swapped separately; if the processor fails the whole board must be replaced.

What thermal limit appears first when the 1.8 GHz dual-core chip runs flat-out?

The 3865U hits its built-in thermal ceiling under sustained load, forcing the firmware to reduce clock speeds until temperatures drop.

How much fan noise and heat should I expect from this Latitude 3480/3580 board during all-day use?

With a low-power 3865U at 1.8 GHz the system stays cool enough that the fan runs quietly most of the time, only spinning up briefly during heavy bursts.
