Acer Aspire ES1-520 LA-D121P is a laptop motherboard designed by Compal and used in the Acer Aspire ES1-520, Acer Aspire ES1-521, Acer Aspire ES1-522 and Acer Aspire ES1-520ES1.

The catalog has 2 schematics, 1 boardview file and 10 BIOS files for it, posted between 2017 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 .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 8 MB chip sizes. 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 B5W1E.
