Are there any news on this? I have 100% identical issue, was waterdamage, but it worked at first, only when I fixed waterdamage, it became *this*.

As I've said, it behaves totally ok. Board visually ok (I'm an experienced board repair tech, checked all the stuff I could think of). Full 20V always, fan spins. Yesterday after memtest however I couldn't make it boot anymore. Now I came to work and it turned on on 2nd attempt (while CPU was still cold). Will run stress tests on CPU and GPU right now since I got a boot. I'm suspecting dying iGPU. We'll see. Had benchmarks for 2h, 75-80C most of the time (bottom lid was off). Now while it's hot it won't boot anymore, only black screen with backlight on over 20 attempts. I think I'm gonna declare it a dead CPU. Evidence for CPU is, so to say, circumstancial, but it looks like a duck, quacks like a duck and boots like a duck. Will offer board replacement and data recovery and will call it a day. Thanks for participating in the discussion (but the device is still here, so if there is some fresh idea, I'm all...ehm...eyes)

You're welcome to propose new idea/solutions. I marked it as no fix and offered board replacement with data transfer (luckily the last working port will let me make a backup without problem). For a pair of days it will be around, then I will give it back to the customer. Still curious about what it could be, guess will never know tho.
