About this board

This thread is for the Lenovo Legion5 Pro 16IAH7H with main board NM-E231.

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. This listing is for revision A0; another revision of the same board can need a different file.

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.

Before flashing, always read and save the original chip. It holds the serial number, UUID, MAC address and ME data for that exact machine.

Hi,
Today I downloaded and tried to flash the firmware for the Legion 5 16IAH7H NM-E231 from you, but unfortunately, it didn't solve my issues.
Specifically, after an official update, the keyboard stopped working altogether. Additionally, when I try to shut down the laptop, the screen goes black, but the fans immediately start spinning at maximum speed.
I analyzed the original BIOS dump and found that the ME region version is 16.1.35.2557. I tried to clean the ME region myself, but due to severe corruption, Intel FIT (MFIT) refuses to open the firmware file.
Could you please advise on what to do or help me fix/clean the original dump?
Thank you!

Really Sorry bro My mistake wrong file upload
I can adjust the file above post number 11 try now and update
Hello again.

I tried your firmware, but unfortunately, it didn't help. The issues with the non-working keyboard and audio are still there. Do you have any ideas on what else could be wrong? Maybe I need to replace the BIOS chips themselves?

Thanks

This is a display, but when you turn it off in Windows, the display turns off, but the power button and fans remain on. The device only turns off when the power button is pressed.

Check motherboard most probably the problem is with wifi card or wifi slot in this condition
