This page collects service files for the Asus E402SA board, fitted to the Asus E402SA.

The catalog has 1 schematic, 1 boardview file and 3 BIOS files for it, posted between 2021 and 2024 across 4 Telegram channels. Each download button opens the original Telegram post.

The files are marked Rev 2.1; 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.

Frequently asked questions

Which revision of Asus E402SA do I have?
Files for this board mention Rev 2.1. 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 Asus E402SA boardview file?
The boardview for Asus E402SA is available as .BDV. .BDV usually opens in OpenBoardView (free) or FlexBV. See What Is a Boardview File and Why You Need One.
What should I check before flashing the Asus E402SA BIOS?
Read the original chip with a programmer and save two copies before writing anything. A dump from another board carries that board's serial number and MAC address, so restore yours from the backup.
