Genuine Dell OEM motherboard for Inspiron

This is a genuine Dell OEM system board carrying part number 1NFHD. It fits the Inspiron 5391 and Vostro 5391 laptops that use integrated Intel graphics only. The board ships with the processor and memory already soldered in place.

Integrated Intel Core i3-10110U at 2.1 GHz

The on-board dual-core CPU runs at 2.10 GHz and shares the 4 GB of soldered memory with the integrated graphics subsystem. Because the silicon and memory are fixed, thermal output and power draw remain consistent with the original laptop design. No discrete graphics option is supported on this board.

No discrete graphics support

This motherboard works solely with systems that rely on integrated Intel graphics; it will not fit models equipped with a discrete GPU. The 4 GB of memory cannot be upgraded, so buyers needing more capacity must choose a different board.

Questions about this item

How do I install the Dell 1NFHD motherboard in my Inspiron 5391 and which step is often missed?

Remove the battery, disconnect the display and I/O cables, swap the board, then re-apply thermal paste to the on-board i3-10110U before refitting the heatsink; skipping the paste causes immediate throttling.

What maintenance or replacement will the on-board 4GB memory need later?

The 4GB is soldered to the 1NFHD board so it cannot be upgraded; if capacity becomes insufficient the only fix is replacing the whole motherboard.

What limit appears first when the i3-10110U runs sustained loads on this board?

The 2.10 GHz dual-core CPU shares a thin laptop heatsink, so thermal throttling kicks in before power or memory bandwidth becomes a bottleneck.
