Replacing motherboard asus n56vz?

Question

ASUS

Asus n56vz laptop motherboard burned out, ordered, received, installed. I even managed to install Windows. Despite the fact that everything was displayed correctly in the BIOS, the laptop turns off after 30 minutes. Processor temperature - 50-55 degrees. In AID shock test - 30 min. and incl. I asked a question to the seller on Ali, he says that it is necessary to solder the BIOS chip from the old board. Processor i5-3210 M - full-time, memory - too. What to do, really solder?
Nothing gets hot, no blue screen. Just 30 min. passed and shutdown. I turn on the same and again for half an hour.

Answer 1

Cutting down exactly in half an hour is most likely the result of Intel anti-theft technology. Useless feature of Intel's security plan.
If in a laptop with a chipset 3 pok. HM70 (younger, with support for current celerons and stumps) put i3 i5 i7 - then the laptop will start and work. But - exactly half an hour. On the older HM76 and others, all the proces lines start up perfectly.
Verdict: either on the board after the Chinese (repair), or from the factory, by some miracle it turned out to be a junior chipset (which i3 does not support and should not be on this board), or the board just has a bug. The bug is treated by hardware flashing the BIOS completely, with a clean ME region. And the wrong chipset is only a replacement for an older one, or put up with and live with hemp

Answer 2

So I did it - half an hour in BIOS - I filmed it on camera, sent it to the dispute commission on Ali. Well, the reason is not clear. And I don't believe in returns.

Answer 3

Leave it in the BIOS for half an hour, it will pass out - technical malfunctions, it will not pass out - look in Windows for events labeled "Critical".
What Windows rolled?
