Acer Nitro 55 FH52M LA-J891P is a laptop motherboard designed by Compal and used in the Acer Nitro 55 FH52M, Acer Nitro 5 AN515-52 and Acer Nitro 5.

The catalog has 2 schematics, 3 boardview files and 7 BIOS files for it, posted between 2021 and 2023 across 3 Telegram channels. Each download button opens the original Telegram post.

File names mention 3 board revisions (Rev 0.1, 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.

Frequently asked questions

Which laptops use the LA-J891P motherboard?
File names in the catalog tie LA-J891P to the Acer Nitro 55 FH52M, Acer Nitro 5 AN515-52 and Acer Nitro 5. Laptops sold under one model name can use different boards, so confirm by the code printed on the motherboard.
Which revision of LA-J891P do I have?
Files for this board mention Rev 0.1, 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-J891P boardview file?
The boardview for LA-J891P 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-J891P 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.
