About this board

Files for the Lenovo Ideapad slim 3 15IAH8 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.

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 Lenovo Ideapad slim 3 15IAH8 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."

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?
