Genuine Dell OEM replacement board for Inspiron

This genuine Dell OEM motherboard carries the Dell part number PKNWK and is built for the Inspiron 7391 2-in-1 laptop. It arrives with an on-board Intel Core i5-10210U quad-core processor running at 1.6 GHz and 8 GB of soldered memory already installed.

Direct swap for a failed original system board

The board replaces the factory system board in an Inspiron 7391 2-in-1 when that board has failed or been damaged. Because the CPU and RAM are integrated, the upgrade path is limited to a straight like-for-like exchange rather than a component-level improvement.

Verify the exact model

Confirm that the laptop is an Inspiron 7391 2-in-1 and that the service tag or chassis label references part number PKNWK. The processor and memory are not removable, so the unit cannot be adapted to other Dell models or configurations.

Questions about this item

Will the PKNWK motherboard fit my Inspiron 7391 2-in-1 chassis?

The PKNWK board is a genuine Dell OEM part built for the Inspiron 7391 2-in-1, so it matches the original mounting points and connector layout exactly.

What is the correct way to install this board, and which step is often missed?

Replace the board, reconnect every flex cable and the battery, then run the Dell service-tag BIOS update; skipping the BIOS flash leaves the new i5-10210U unrecognised.

Since the RAM is soldered, what maintenance or replacement should I expect later?

The 8 GB is on-board and cannot be upgraded; if a memory fault appears the whole board must be swapped, so keep the system cool and dust-free to extend its life.
