About this board

Files for the Lenovo Ideapad slim 3 15IAH8 motherboard, board number NM-F331.

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)

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.

If you have a working file for this board, please share it below. More files: search NM-F331 in File Finder.

"Now it's fine, it detects the HDD and boots the operating system, but what happens is when it gets turned off overnight, in the morning nothing responds until I remove both the main battery and the BIOS battery. After that, it turns on... and it's like this every time: when it's turned off, the next day it can't be turned on until I perform the procedure I previously explained."

Check motherboard this is not bios related problem.
Check rtc section and rtc crystle on the motherboard.

Check rtc section and rtc crystle on the motherboard.

The BIOS version is LTCN44WW, but the Product Name, MTM, and Lenovo SN are all showing as INVALID.

Can you help me write in these missing data in the BIOS that are currently showing as invalid?
