About this board

This thread is for the Thinkpad T460 (Type 20FN) with main board NM-A581.

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 3.0; another revision of the same board can need a different file.

Files usually needed for this board
  • BIOS (full SPI chip dump, .bin)
  • EC / KBC firmware, if the board uses a separate EC chip
  • Schematic (PDF)
  • Boardview (.brd / .bdv / .cad)

Typical reasons to reflash: no power or no display after a failed BIOS update, a BIOS/supervisor password lock, or a corrupted Intel ME region.

Before flashing, always read and save the original chip. It holds the serial number, UUID, MAC address and ME data for that exact machine.
