The catalog has 1 boardview file and 1 BIOS file for it, posted between 2021 and 2023 across 3 Telegram channels. Each download button opens the original Telegram post.

The files are marked Rev 2.0; 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.

Frequently asked questions

Which laptops use the NM-B271 motherboard?
File names in the catalog tie NM-B271 to the Lenovo ThinkPad X1. Laptops sold under one model name can use different boards, so confirm by the code printed on the motherboard.
Which revision of NM-B271 do I have?
Files for this board mention Rev 2.0. 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-B271 boardview file?
The NM-B271 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-B271 BIOS?
Read the original chip with a programmer and save two copies before writing anything. A dump from another board carries that board's serial number and MAC address, so restore yours from the backup.
