About this board

ideapad 320-15IKB DG421 DG521 DG721 — motherboard NM-B242.

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.

Files listed for this board
  • BIOS (full SPI chip dump, .bin)
  • 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.

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