Lenovo G400S LA-9901P is a laptop motherboard designed by Compal and used in the Lenovo G400S and Lenovo G500S.

The catalog has 2 schematics, 2 boardview files and 3 BIOS files for it, posted between 2018 and 2026 across 5 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 .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.

Read and save the original chip contents before you write anything to it — Keeping the Windows Product Key (MSDM) When Reflashing a BIOS.

How do I open the LA-9901P boardview file?
