Hello everyone,
I’m currently working on a dead MSI GP75 Leopard (MS-17E71) motherboard (i7 CPU, NVIDIA GPU) with a no display/no backlight issue initially. After extensive investigation, I’m at a critical stage involving EC firmware, BIOS/ME region interaction, and possible deep corruption. I'm seeking advanced insight from anyone with experience in EC/BIOS sync issues or PCH-level behavior. Here’s a full breakdown:
🧩 Initial Issue- Board powers on (fans spin, keyboard lights up and can be adjusted, caps lock led lights), but no display or backlight
- External display (HDMI) shows

So a couple of years ago i got a bios update through Lenovo Vantage, so i installed it and bricked my whole BIOS, so i couldn't fix it so i put that ideapad in a box, 3 years later i found that one PC and want to recover it to switch from a 2014 hp laptop to this one.
I found a method to recover the BIOS of many lenovo laptops tha consists in pluging in a USB Flash with the BIOS files and power on the laptop with Fn + R keys pressed until fans go loud and start beeping loud, but nothing worked, so i think filename is wrong, i tried naming the bios file as 07WW.BIN, BIOS.BIN, BIOS.fd,...10-11-2024, 03:12 PM
