Lenovo G505S LA-A091P is a laptop motherboard designed by Compal and used in the Lenovo G505S, Lenovo Z505-LA-A091P, Lenovo G405S and Lenovo G505S-LA-A091P.

The catalog has 1 schematic, 2 boardview files and 4 BIOS files for it, posted between 2017 and 2026 across 4 Telegram channels. Each download button opens the original Telegram post.

File names mention 2 board revisions (Rev 1.0 and Rev 1A). 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-A091P motherboard?
File names in the catalog tie LA-A091P to the Lenovo G505S, Lenovo Z505-LA-A091P, Lenovo G405S and Lenovo G505S-LA-A091P. Laptops sold under one model name can use different boards, so confirm by the code printed on the motherboard.
Which revision of LA-A091P do I have?
Files for this board mention Rev 1.0 and Rev 1A. 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-A091P boardview file?
The boardview for LA-A091P 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-A091P 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.
