Yes, I know. I need the bin file to program my BIOS. Do you have one that works for this motherboard?
Thanks

Maybe.
At first, I need program the new bios IC with a firmware running, because its empty right now. Do yo have a bios file to share with me?
Thanks.

Thanks. I programmed the BIOS with your file, but nothing changed. I have the same result with other bios files that I have. The laptop still hasn't video output. All the voltages are present. As for the current draw on the oscilloscope, I see an initial frame and then a constant current of around 500mA without any change.

So, the only thing left to check are some signals from the EC and AMD CPU (with the PCH inside). From what I've seen, PLTSRC isn't activating at all. Does this mean my CPU is damaged?

What do you think @ThienBui ? Maybe the CPU/FPH its damaged?
