Dell Latitude E5430 LA-7901P is a laptop motherboard designed by Compal and used in the Dell Latitude E5430 and Dell Latitude 5430.

The catalog has 2 schematics, 2 boardview files and 14 BIOS files for it, posted between 2019 and 2024 across 4 Telegram channels. Each download button opens the original Telegram post.

The files are marked Rev 1.0; other revisions of the same board can differ in parts and layout.

The boardview comes in .BRD, .BDV and .CAD 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.

BIOS notes: file names mention 4 MB and 8 MB chip sizes; some archives also hold EC/KBC firmware. 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 QXW00.

Read the original chip with a programmer and save two copies before writing anything. File names for this board mention 4 MB and 8 MB images; the dump size must match your chip.

A dump from another board carries that board's serial number and MAC address, so restore yours from the backup.
