Did they quote you on how much it would cost to fix the board? also thank you for the reply!

Not really. According to HP support the issue comes from the fans. They charge 230$ + a 30% discount. Even if i told them that i already replaced the fans myself by trying to fix the issue.

Hey Guys,

 I think I got an anwnser for our problem!

(But sadly no sulution 😔)

After a Technician (my cousin) looked at it for several hours and tried many different things, we came to the conclusion that a Thermal Senser at the Graphics Card is broken. It jumps every few seconds to 100°C, even if the Card is at a completely normal temprature. And the Laptop won't start if it's componetns are overheating.

We tried to disable the Card and run the laptop with the internal graphics card, but sadly, it didn't work.

Without knowing where this sensor is, we can't fix the laptop.

If the Sensor is under the graphics card (between the mainboard and the keyboard) we could have a chance. But we didn't disassambled it. (I think we would need to remove everything to get to the other side)

If it's just a really small chip on the mainboard or inside the card, then the laptop is probably dead.

For me, the laptop is dead. I give up now. Even if we find the sensor, we would need a replacement part.

I removed the SSD and the Hard Drive and Run it with two adapters from an different computer.

I just wanted to share my experience with you. Maybe someone finds it, and knows how to fix it, then I might consider to repair it, but for now the laptop is dead for me.

(I can't acces it with the F2 trick anymore, I don't know why)
