Just flashed your file with DMI data transferred from my original backup, but same behaviour, black screen and shuts down after 20-25 seconds ...

Sadly there is no serial number or information visible on the bottom cover, however I found that if I scan the QR code on a sticker near the touchpad, loads a support webpage with the following info:

Hi, I have this machine on the work bench (Lenovo IdeaPad/NM-D031/GS454/GS554/GV450/GV550 board, no DGPU).

I’m trying to diagnose a power-on issue and I would appreciate some guidance or a clean BIOS rebuild.

• Board powers on correctly
• All power rails remain stable
• No video is ever produced
• System always shuts down after ~20-25 seconds (very consistent timing) and requires full power cycle to restart.
• BIOS was previously reflashed with a known-good image and cleaned ME region (when reflashing with clean ME region it power cycles several times but then shuts down and returns

...

Thank you. With your BIOS flashed, the laptop successfully boots into Windows using the iGPU. However, when switching to the dGPU (RTX 4060) via the MUX switch, after restarting there is no display output. I am forced to reflash the BIOS each time to restore the image through the integrated graphics. Any thoughts? I’m also attaching what I believe is the original EC firmware from a 2MB Winbond chip. Could this be the issue?...

Hi, I have a Thunderobot Zero 16 Laptop. All voltages are fine but no video so I'm suspecting corrupted BIOS.

Hi, I hope someone can help me with this, my Dell G15 Ryzen Edition does not post anymore (black screen, no Windows boot, no BIOS screen) after Windows Update pushed what appears to be a buggy bios image, I've tried the following with no success:
