Dell Latitude 5540 LA-H331P is a laptop motherboard designed by Compal and used in the Dell Latitude 5540, Dell XPS 7590, Dell XPS 9575 and Dell Precision 5540.

The catalog has 1 schematic, 1 boardview file and 11 BIOS files for it, posted between 2021 and 2026 across 3 Telegram channels. Each download button opens the original Telegram post.

File names mention 2 board revisions (Rev 0.2 and Rev 1.0). Check the revision printed on your PCB before relying on a boardview or flashing a BIOS dump — How to Open .FZ Boardview Files explains why it matters.

The boardview comes in .BDV format. OpenBoardView (free) usually opens these files; FlexBV works too. See OpenBoardView: Installation and First Steps.

With both a schematic and a boardview you can find a net on the diagram and then locate the same part on the board by its reference designator. No Boardview for Your Board? How to Work Without One shows the workflow.

BIOS notes: file names mention 4 MB and 32 MB chip sizes; versions with a cleaned ME region are included. Read and save the original chip contents before you write anything to it — Keeping the Windows Product Key (MSDM) When Reflashing a BIOS.

Also listed under platform EDB51.

Files for this board mention Rev 0.2 and Rev 1.0. The revision is printed on the PCB silkscreen, usually next to the board code. Pick files with the same revision when you can; if yours is not listed, the closest revision is usually fine for the schematic but check part positions in the boardview carefully.
How do I open the LA-H331P boardview file?
The boardview for LA-H331P is available as .BDV. .BDV usually opens in OpenBoardView (free) or FlexBV. See What Is a Boardview File and Why You Need One.
