About this board
Files for the Yoga 900-13ISK2 motherboard, board number NM-A921.
Lenovo had this board built by LCFC; LCFC (Lenovo/Compal) board numbers start with NM-. Check the number printed on the PCB before you download.
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.
