Lenovo ThinkPad X13 NM-C891 is a laptop motherboard designed by LCFC and used in the Lenovo ThinkPad X13.

The catalog has 1 schematic, 1 boardview file and 4 BIOS files for it, posted between 2022 and 2024 across 3 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 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: 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 GX3A2.

Frequently asked questions

Which laptops use the NM-C891 motherboard?
File names in the catalog tie NM-C891 to the Lenovo ThinkPad X13. Laptops sold under one model name can use different boards, so confirm by the code printed on the motherboard.
Which revision of NM-C891 do I have?
Files for this board mention Rev 1.0. 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 NM-C891 boardview file?
The NM-C891 boardview comes inside an archive whose name does not state the format. Unpack it and check the extension; most laptop boardviews open in OpenBoardView or FlexBV. See What Is a Boardview File and Why You Need One.
What should I check before flashing the NM-C891 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.
