Hello.
I came to a very weird situation with a T470.
Laptop worked great but locked, backed up the BIOS, successfully verified it, patched it with Autopatcher, boot successfully and completed the DXE procedure, flashed back the old unpatched bios and now only the green led of power button turns on and nothing else.
Tried CMOS reset but no luck. No physical damage around BIOS chip, i was very careful and checked MB on microscope.
Any ideas?
Both bios attached

Dear Friends., working on a Lenovo T470. All required voltages are present & the require Amps (.95mili amps), Also goes through the start process, turns off & then turns on but no display or any beeps. I think the BIOS Bin files are corrupted & has to be re-build. Can some pls. re-build the Bin File, Original Bin uploaded. Thanks in advance.

Hello.
This laptop starts normally, the power button lights green, and the fan turns on. A few seconds later the power button light goes out and the fan stops spinning, the laptop never boots and the screen stays black. The laptop was working untill a windows BIOS update failed, I'm looking for a clean BIOS bin file or a clean up of the corrupted BIOS dump. Any help would be greatly appreciated Thank You.

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

Hello, I was flashing the bios but now the machine does not come, the battery indicator turns orange when charge is plugged in.

Hi, I have an MSI PRO B660M-G DDR4 board with damaged BIOS and i need a bios dump from a real board, along with MAC, UUID and Serial Number info (eg. a BIOS screenshot and pictures from the board stickers).
I need to reconstruct the bios on my board, based on another bios image form a real board - meaning a bios image containing MAC address, UUID and Serial number. A stock BIOS is not suffiecient, as it is impossible to discover where the MAC, UUID and SerialNumber are stored. Tried with a similar board, but there are too much differences, and the stock BIOS is missing a lot of...11-17-2023, 10:56 AM -
