Acer Nitro 54 EH50F LA-H431P is a laptop motherboard designed by Compal and used in the Acer Nitro 54 EH50F.

The catalog has 1 schematic, 2 boardview files and 1 BIOS file for it, posted between 2021 and 2022 across 2 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 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.

Also listed under platform Compal EH50F.

Frequently asked questions

Which laptops use the LA-H431P motherboard?
File names in the catalog tie LA-H431P to the Acer Nitro 54 EH50F. Laptops sold under one model name can use different boards, so confirm by the code printed on the motherboard.
Which revision of LA-H431P do I have?
Files for this board mention Rev 1.0. 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-H431P boardview file?
The boardview for LA-H431P is available as .BRD. .BRD 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-H431P 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.
