The laptop does not turn on, what could be the reason?

Question

Do it yourself

When you turn on the laptop, the power and network connection indicators are on properly. The cooler starts spinning, the HDD indicator lights up and then everything stops working (the cooler and the HDD indicator are cut down), the monitor does not light up at all, and the power indicator and the power button glow further (as in normal working condition) - brick mode.
Sometimes it starts ... HDD works (the indicator too), the screen shows as it should. If I boot in safe mode everything works fine. If you load it as usual, then after 1 minute - 30 seconds, the blue screen of death turns on, writes dump hard disk and that's it. If you reboot and try to start again, the brick mode may turn on again .... and the filling is still very hot

Answer 1

Under the process is a temperature sensor. here it sometimes does not allow you to run. but in general you have overheating

Answer 2

I recently dealt with a laptop of the same manufacturer and about the same age.
The problem was not overheating, memory, HDD, BIOS, power adapter, battery.
The defect manifests itself as follows: The
laptop on a cold normally turns on and boots.
After a reboot or when you turn it on again, the Acer splash screen appears, then a black screen and nothing else happens. The laptop will rest for 5 minutes without a power cord and battery - it turns on again and works until the next reboot.
When installing software from the Acer website, the laptop was cut down when loading after about 30 seconds.
Try removing the battery, let the laptop rest without power for an hour, and see what happens when you turn it on.

It all started with NEHER. I played in RimWorld, I had to get a laptop. He put it into hibernation, pulled it out of the socket, closed it, hid it. After an hour and a half I got it, and he was already dead. It won't turn on when cold either. In those cases when it turned on, went into safe mode, did a rollback, restore, turned on / off services in turn, ran the last known good configuration (or whatever). All the same - either a brick or a blue screen. Today I took it apart, removed the dust with a brush, tomorrow I will buy thermal paste, I will replace it. I poke the operative .... I hope the old woman starts up.

1- устранить перегрев чисткой.2- загрузится с лайф-диска и протестировать hdd. Если после этого дефект остался - разбираем, греем кратковременно северный мост и смотрим на реакцию. Заработал после прогрева - значит менять север. Не помогло- греем видео, если есть.
Ps по описанию все признаки дохлого чипа.
