About this board
Files for the Lenovo Ideapad 5-15IIL05 motherboard, board number NM-C681.
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 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.
Back up the original dump first — it contains machine-specific data (serial, UUID, MAC, ME), and you will want it if anything goes wrong.
