Dell Latitude 3550 LA-B072P is a laptop motherboard designed by Compal and used in the Dell Latitude 3550 and Dell 3550.

The catalog has 3 schematics, 3 boardview files and 2 BIOS files for it, posted between 2019 and 2022 across 3 Telegram channels. Each download button opens the original Telegram post.

The files are marked Rev 0.1; other revisions of the same board can differ in parts and layout.

The boardview comes in .BDV, .CAD and .BRD format. .CAD files usually need FlexBV or the viewer they were exported for; OpenBoardView handles .BRD, .BDV and .FZ. 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.

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 ZAL60; codes LA-B071P.
