Genuine Dell OEM Motherboard for Inspiron 2-in-1

This genuine Dell OEM motherboard carries part number FJ7F9 and includes an on-board Intel Core i7-10510U quad-core processor running at 1.8GHz. It is built as a direct replacement system board for the Inspiron 7591 2-in-1 and Inspiron 7791 2-in-1 laptops that use integrated Intel graphics.

Replaces the Original System Board in UMA Models

The board replaces a failed or damaged motherboard in the same chassis when the original unit shipped with integrated graphics (UMA). The jump is worth it when the existing board no longer posts, shows video artefacts, or has damaged power circuitry, because the CPU is already soldered on and no separate processor purchase is needed.

Suits Owners of UMA 7591 or 7791 2-in-1 Units

This part suits owners of the Inspiron 7591 2-in-1 or 7791 2-in-1 who have confirmed their machine uses integrated Intel graphics. Buyers whose laptops shipped with discrete Nvidia graphics should look elsewhere, as this motherboard is not compatible with those configurations.

Questions about this item

Which Dell Inspiron models does the FJ7F9 motherboard fit?

The board is a direct replacement for the Inspiron 7591 2-in-1 and the Inspiron 7791 2-in-1, both with integrated Intel graphics only.

What is the correct installation step for the on-board i7-10510U processor?

The CPU is already soldered to the board, so you only need to mount the board, connect the cooler, and attach all ribbon cables — no separate CPU installation is required.

When should the CMOS battery on this board be replaced?

Replace the coin-cell battery when the system loses date and time settings after being powered off, typically after several years of use.
