Lenovo ThinkPad Yoga 370 LA-E291P is a laptop motherboard designed by Compal and used in the Lenovo ThinkPad Yoga 370 and Lenovo Yoga 370.

The catalog has 1 schematic, 3 boardview files and 5 BIOS files for it, posted between 2021 and 2026 across 5 Telegram channels. Each download button opens the original Telegram post.

File names mention 2 board revisions (Rev 0.3 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, .FZ 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 CIZS1.

Which revision of LA-E291P do I have?
Files for this board mention Rev 0.3 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-E291P boardview file?
The boardview for LA-E291P is available as .BDV, .FZ and .CAD. .BDV and .FZ 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-E291P 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.
