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

Please post any suggestions and corrections about the BIOS guides, methods, resources and tools thread here.
TODO:- Add list of known suffixes for Dell
- Complete list of programmable/non-programmable EC
- Add more platforms with automatic EC flashing
- Add more brands for BIOS extraction
- Add EC firmware extraction process
- Probably a lot of other stuff I forgot
