If it no longer boots with the original ones then youve dislodged a resistor, damaged the bios chips from excessive heat or broken the traces.

Hello, I have been lurking the forums for a few hours and just wanted to make sure my understanding of the process is correct. From what I can tell, none of the HP flash tools will work for this laptop (645 G9), and the BIOS must be manually edited by someone. From my understanding you cannot just remove the password from the BIOS and reflash it, the entire DMI must be erased. I believe only the SPI ROM chip is flashed, and the EC ROM chip is not touched. I have read Rex98's process for the first two boots after flashing a new BIOS. Then the HP BCU is used to edit the BIOS DMI values back to their factory values. Are there any resources for learning how to manually edit the BIOS dump myself? I am waiting on a CH341A flash tool to arrive so it would be cool to learn how the BIOS files are being edited. If it's just easier for me to post the dump here and have someone do it for me I understand.

I have tried searching on the forums for more info, but the few threads I have seen asking a similar question were just hijacked by people asking "please fix BIOS".

Slightly off topic, I have a 645 G9 here with Ryzen 5 PRO 5675U.
Could anyone please measure the resistance to ground on the leftmost coil/inductor to the CPU.
Mine is 2.2 Ohms, which doesn't look good to me 😢
I have one which has a blown inductor component above the driver chip to this coil, and I am wondering whether the CPU is shorted/dead.
Thanks to everyone willing to give a value.
