The board was manufactured by Wistron for Lenovo. Wistron board numbers are 5–6 digits plus a revision, so you can confirm it on the PCB silkscreen.

Files usually needed for this board

BIOS (full SPI chip dump, .bin)
EC / KBC firmware, if the board uses a separate EC chip

Boardview (.brd / .bdv / .cad)

Common cases: dead board after an interrupted BIOS update, ME region errors, missing serial number or UUID after a board swap, or a password lock.

Back up the original dump first — it contains machine-specific data (serial, UUID, MAC, ME), and you will want it if anything goes wrong.
