Lenovo ThinkPad L13 Yoga 18834-1M is a laptop motherboard designed by Wistron and used in the Lenovo ThinkPad L13 Yoga, Lenovo ThinkPad L13, Lenovo ThinkPad L13LAR-1 and Lenovo ThinkPad LAR-1.

The catalog has 4 schematics, 2 boardview files and 2 BIOS files for it, posted between 2022 and 2026 across 4 Telegram channels. Each download button opens the original Telegram post.

The boardview is packed in an archive and the file name does not say which format is inside; most open in OpenBoardView or FlexBV. What Is a Boardview File and Why You Need One lists the common formats.

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 1 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 Wistron ARES; codes 18834-1N, 448.0HK02.
