Hallo,

I'm looking for a BIOS file for the Samsung Galaxy Book3 Ultra. Laptop is showing 'SAMSUNG' logo and then powers off.

Model: NP960XFH-XA3NL
Serial: 67GQ9FFW800042T
M/B Partnumber: BA92-24579B
M/B Modelnumber: VENUS3_16_EXT

PlatformID: ALQ

I followed the guide titled "ID Samsung BIOS from dump and download the official update" and downloaded the file ITEM_20240619_22402_WIN_P07ALQ.exe. After extracting it, I got a .bin file, but it's slightly smaller than my original BIOS dump, so I can't use it directly....

Hello everyone,

I’m working on a Lenovo Legion 5 15IMH05H motherboard (ID: NM-C911R, Ver. 1.0).
I’ve encountered an issue with the NVIDIA GPU chip, so I removed the chip itself along with its MOSFETs and coils. I also removed the VRAM MOSFETs and their corresponding coils.

After doing that, the laptop powers on and off — it turns on for a short moment, then shuts down, then powers up again for about a minute before the fan ramps up to full speed and the system shuts down again. Throughout this process, the screen remains completely black.
