Lenovo ThinkPad X380 LA-F421P is a laptop motherboard designed by Compal and used in the Lenovo ThinkPad X380, Lenovo ThinkPad X380 Yoga and Lenovo ThinkPad X280.

The catalog has 1 schematic, 1 boardview file, 6 BIOS files and 2 archives for it, posted between 2020 and 2026 across 4 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 .CAD format. .CAD files usually need FlexBV or the viewer they were exported for; OpenBoardView handles .BRD, .BDV and .FZ. See How to Open .PCB and .CAD Boardview Files.

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; versions with a cleaned ME region are included. 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 DTZS1.
