Hi all. One of my clients went with the same issue, so I reviewed deeply and I found the exact trouble. The cooling system of this particular model is very deficient. So the processor joints have broken (maybe more than one). The only solution here is to make a reballing to the mainboard. I already did this and the laptop at last started as before. I really don't know if this solution will be permanent, but for this time is enough. Greetings, Ph0B0s
