Help i Need Bios bin Asrock B550 Steel Legend...
-
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

I've got an ASRock B450 Steel Legend that I'm trying to diagnose for no reaction to the power button.
The SIO receives the PWRBTN# signal and sends PSOUT#, but the CPU doesn't return SLP_S3# so nothing further happens. I have been looking around the board trying to figure out why and I happened to touch the STEP-DOWN CONVERTER NB685GQ-Z (UP10 in photo) which was VERY hot (like burn your finger). This seems to provide VDDP_S5, and indirectly, VDDCR_SOC_S5, which the CPU needs in order to handle the startup signals.
The VCC voltage powering the converter does not look right.... -
