Acer Aspire 3 A317 LA-H781P is a laptop motherboard designed by Compal and used in the Acer Aspire 3 A317, Acer Aspire 3 A317-51K, Acer Aspire 51KG and Acer Aspire 3224.

The catalog has 1 schematic, 2 boardview files and 2 BIOS files for it, posted between 2021 and 2023 across 3 Telegram channels. Each download button opens the original Telegram post.

File names mention 2 board revisions (Rev 1A and Rev 1B). Check the revision printed on your PCB before relying on a boardview or flashing a BIOS dump — How to Open .FZ Boardview Files explains why it matters.

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: 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.

Which laptops use the LA-H781P motherboard?
File names in the catalog tie LA-H781P to the Acer Aspire 3 A317, Acer Aspire 3 A317-51K, Acer Aspire 51KG and Acer Aspire 3224. Laptops sold under one model name can use different boards, so confirm by the code printed on the motherboard.
Which revision of LA-H781P do I have?
Files for this board mention Rev 1A and Rev 1B. 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 LA-H781P boardview file?
The boardview for LA-H781P 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 LA-H781P BIOS?
Read the original chip with a programmer and save two copies before writing anything. Some archives include EC/KBC firmware, which may need to be written to a separate chip. A dump from another board carries that board's serial number and MAC address, so restore yours from the backup.
