About this board

Files for the Legion S7-15ACH6 BM5070-V1.4 BM5070 motherboard.

Compare the board number printed on the PCB (near the RAM slots or under the battery) with the files before you flash.

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)

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.

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