About this board

HD photos of the NM-C931 main board from the Lenovo Thinkpad T14 Gen 1. Use them to find burned or missing parts, check component values and compare the layout with your own board.

The board was manufactured by LCFC for Lenovo. LCFC (Lenovo/Compal) board numbers start with NM-, so you can confirm it on the PCB silkscreen. This listing is for revision 1.0; another revision of the same board can need a different file.

Also useful for this board

EC / KBC firmware, if the board uses a separate EC chip
Schematic (PDF)
