MSI ge62vr Apache Pro 6RF EC BIOS dump

[Cautious-Grass]

I have a MSI ge62vr Apache Pro 6RF. I'm having an issue with this repair that I haven't been able to find a resolution for with my usual sources, so I'm coming here on recommendation from Reddit. A customer decided to attempt to manipulate voltage to the fans through the EC, his laptop shut down and he was not able to get it to come back on. I did a power flush, EC reset, etc. didn't work. Took out my multimeter, no power was going from the charger to the battery. Checked with a different charger. Power was going from the charger to the inlet, but not the battery. Replaced the power inlet, and it was going to the battery port but the battery wasn't receiving it. Replaced the battery and FINALLY was getting voltage to the board, but it was lower than I expected. I bought a replacement CMOS battery and the voltage is around where I think it should be, but I still can't power on the laptop. I even attempted replacing the fans to see if that helped. Throughout this entire ordeal, I was attempting EC reset, power cycling, etc. and had no success. I have some tech knowledge since I am a repair technician, but this is entirely unfamiliar territory to me and I would appreciate if it was dumbed down a bit since the information I'm navigating is overwhelming and I want to do this repair correctly. I was told to get a TL866II find an EC + BIOS dump. I found a some files on the MSI website, but I don't know if it's just an update file or if it is what I need. https://us.msi.com/Laptop/GE62VR-Apa...X-1060/support

What did your client did? If he was manipulating the ec you should check this ic different signals and voltages before you buy a programmer. Ofc most probably the issue is there since this ic receives and send different enable and power_good signals.
