Genuine Dell Inspiron 11 Motherboard

This genuine Dell system board carries the RJ80P part number and an on-board Intel Celeron N2815 dual-core processor running at 1.86 GHz. It is built specifically for the Inspiron 11 (3138) notebook and restores the original platform without modification.

Sustained load behaviour

The board operates with a bus frequency of 2.13 GHz and supports DDR3L 1066 memory, providing stable throughput for everyday workloads. Thermal management relies on the laptop's original cooling assembly, which must be reapplied correctly to maintain performance during extended use.

Installation notes

Replacing the motherboard requires full disassembly of the Inspiron 11 chassis and careful transfer of the display cable, keyboard ribbon and antenna leads. The most common issue is damaging the fragile ZIF connectors or forgetting to re-seat the wireless antenna cables, which results in no Wi-Fi after reassembly. Buyers needing a different form factor or a socketed CPU upgrade cannot use this board.

Questions about this item

How much heat does the N2815 CPU on this RJ80P motherboard produce during all-day use?

The on-board Intel Celeron N2815 runs at a 1.86 GHz base frequency with a 2.13 GHz bus, a profile designed for low thermal output in the slim Inspiron 11 (3138) chassis.

Which DDR3L memory speed must I already have to install this RJ80P board?

This motherboard supports DDR3L 1066 memory only; your existing SO-DIMM modules must match that speed for the system to post.

Will the RJ80P motherboard fit the original hinges and display cable of my Inspiron 11 (3138)?

The RJ80P is the exact Dell part number for the Inspiron 11 (3138), so mounting points, hinge brackets and the embedded display connector all align with the original chassis.
