Lenovo AIR-14IIL LA-J551P is a laptop motherboard designed by Compal and used in the Lenovo AIR-14IIL and Lenovo AIR-14IIL2020.

The catalog has 2 schematics, 1 boardview file and 3 BIOS files for it, posted between 2022 and 2025 across 3 Telegram channels. Each download button opens the original Telegram post.

File names mention 3 board revisions (Rev 1.0, Rev 1A and Rev 2B). 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 and .CAD format. .CAD files usually need FlexBV or the viewer they were exported for; OpenBoardView handles .BRD, .BDV and .FZ. 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 16 MB chip sizes; 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 FLMS0.

Frequently asked questions

Which laptops use the LA-J551P motherboard?
File names in the catalog tie LA-J551P to the Lenovo AIR-14IIL and Lenovo AIR-14IIL2020. Laptops sold under one model name can use different boards, so confirm by the code printed on the motherboard.
Which revision of LA-J551P do I have?
Files for this board mention Rev 1.0, Rev 1A and Rev 2B. 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-J551P boardview file?
The boardview for LA-J551P is available as .BDV and .CAD. .BDV usually opens in OpenBoardView (free) or FlexBV. .CAD usually needs FlexBV or the matching viewer. See What Is a Boardview File and Why You Need One.
What should I check before flashing the LA-J551P BIOS?
Read the original chip with a programmer and save two copies before writing anything. File names for this board mention 16 MB images; the dump size must match your chip. 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.
