Please restore this BIOS! It turns on, but the screen is black. I accidentally erased the old firmware dump. I tried a couple of firmware options from this forum in the post above, without result. Thanks in advance!

Dear all,
I have recently fixed a Lenovo IdeaPad 3 15 ALC6 that was not booting due to a BIOS issue. After flashing the BIOS, the laptop boots up, but hard disk is not recognized in BIOS. Is says "Hard Disk : Not Installed". I have tried with 2 different drives (one that I know is working on another laptop) but I get the same result. I do not know if disks were recognized before I got the laptop and fix it, but I don't see any reason why not. I can boot on USB though.
Here the steps I have taken to fix the laptop:
- downloaded latest BIOS from Lenovo Website... -
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
