Your original BIOS backup had errors, random data in some places, maybe you were using a WSON8 probe and it moved during reading... When using a WSON8 probe make several backups and compare them with hex editor, should be identical
Try, hopefully fixed, replaced BIOS region and added your S/N etc.

Make a backup of main BiOS, EC firmware can be extracted from there, best to match with original BIOS version

Very likely the fan that burned when connected to the lab PSU was shorted/defective since the beginning, that's why the 12V supply in the board was entering protection mode
PWM signal sent by EC controls fan speed, probably one fan is meant to be controlled based on CPU temp, and the other fan based on GPU temp
That's another thing to check if the PWM pulses are being sentLeave a comment:

Maybe a damaged component caused by liquid damage, start a new thread on Troubleshooting laptops section and post pictures of the liquid damaged area thereLeave a comment:

Previous versions, you need to enable "BIOS back flash" setting in BIOS setup

The problem looks more like a software issue, I suggest to reinstall Windows with Secure Boot enabled, there's a recent Secure Boot certificate update and updated Windows bootloaderLeave a comment:

... And the code should be under battery connector on the motherboard (unplug the battery)Leave a comment:

That means the 12V supply on the laptop is failing under load, if both fans work on the bench PSU
Try plugging in only 1 fan at a time and measure the 12V output at PL4000Leave a comment:

This is not the original BIOS as the S/N is different R910NDFD, it's exactly the same as the one from here, post 50: https://www.badcaps.net/forum/troubl...29#post3806629
If you have the original backup from your laptop, you can transfer your DMI and Win key with hex editor

You read wrong chip, W25Q16JW this is NVIDIA VBIOS for RTX 3060 not "EC", repeated 8 times as you selected a 16MB chip
Please stop calling random SPI flash chips "EC", most EC/KBC/SIO (brand: ITE, ENE, Nuvoton etc.) have internal flash
I don't know if the BIOS chip/the GPU survived that 3.3V being supplied to it and the 1.8V data lines, worth a try flashing it with 1.8V adapter, there's a backup of UG10 at post 197 https://www.badcaps.net/forum/troubl...es/bios-reques...Leave a comment:
