XMG A507VE (Clevo N857EJ1) Fans spin up then shuts down

[nemethma]

Hi! (Sorry for my English)

I buyed a broken XMG A507VE (Clevo N857EJ1) what is normal turn on and the a few minuted its suddenly ramping up the fan speed to max with blinking orange light on the status led.
First I tried to clear the intel ME but that didn't helped, so I write a new bios into it, but that was a failure to.
Then I started searching for electronic problems, I was suspicious for thermal sensors so according to the schematic I changed the RT1 thermistor to a new one. It didn't helped, so I changed the Super I/O because it seems that the thermal sensor vas wired into it. Unfortunately it was a failure again.

I'm out of ideas how to fix this laptop so I'm asking for help.

Does bios recognize dGPU?

I have p170em, old model. When i remove MXM gpu, I have same problem, fans ramp up and computer shuts down. I read that this is because BIOS can't sense dGPU temperature.

The windows is recognised the gpu and the psi afterburner is able top read the temperature so I think its okay but I will going to check te communication.

Thanks for the idea. I will write if anything happens.

What temperatures do you get? Use open hardware monitor. CPU, gpu.
Could be faulty heatsink pipes.

CPU was 45 and GPU was 53 celsius. The heatsink and pipe are fine I'm tested them with a heat gun.
I tested the GPU themp and fan signal it was fine.

Just in case I BGA reballed the GPU but it didn't help(not like I actually thinked it gone work).
