A laptop is the same thing as a computer, which also needs care and careful handling. If you have the slightest suspicion of a laptop breakdown, you need to contact the service center, where specialists can diagnose.
Sudden shutdown (disconnection) of the laptop is a very unpleasant symptom that requires a quick response. In this article, we will look at the reasons for the accidental shutdown of the laptop. What can cause a laptop to suddenly shut down?

The processor in the laptop is overheated
Overheating of the processor in laptops is the most common problem. Acer notebooks with an AMD processor are particularly affected by it.
The BIOS has a protection that turns off or reboots the laptop if the maximum available temperature is exceeded, thanks to which the processors do not burn out from overheating.
Intel has its own overheating protection in the new processors, which does not restart or shut down the laptop, but simply resets the frequency. This action is called throttling.
The laptop temperature can be checked in the Everest program , the Trial version can be downloaded from the link, and there you can also check whether the processor is throttling or not.
If the program shows a high temperature and your processor throttles, then you need to urgently clean the laptop, replace the thermal paste and check the cooling system
If, under load, cold air flows from the cooler and the temperature rises, then it is urgently necessary to change the cooling system. The pictures below show how to find out the temperature and CPU throttling using the Everest program.

The video card in the laptop is overheated and the protection worked
The situation is similar as with the processor. If the maximum available temperature is exceeded, protection is triggered and the laptop turns off.
This often occurs when playing on a soft surface (sofa, rugs, etc.).
The villi are clogging the grilles on the bottom of the laptop, which interferes with the normal flow of air. Because of this, the internal temperature of the laptop rises due to the fact that the cooling system simply does not cope and protection is triggered.

Battery malfunction (if the laptop shuts down while running on battery power)
If the laptop works fine from the mains, does not turn off, does not reboot, but while operating on battery power, it suddenly turns off, then most likely these are problems with the battery or the charge level controller.
You can try to check the contacts on the battery, maybe something got there, but in 99% these are problems with the battery and you cannot do without a service center.
HDD problems
If you hear strange noises under the keyboard, squeaks or clinks before shutting down, then most likely your hard drive is slowly dying. This is especially common with old laptops that are more than 5 years old.
We recommend that you save all important information to a USB flash drive or cloud servers 1TB of memory for storing information in the cloud and contact the service center.
Laptop clogged with dust
Another shutdown of the laptop can occur due to the clogging of your laptop. The internal temperature rises and the overheating protection is activated. It is necessary to clean the laptop.

What can the sudden shutdown of the laptop cause?
- If the laptop turns off due to problems with the processor, then this can lead to its breakdown, the same applies to the video card.
- With any emergency shutdown of the laptop, the HDD suffers, a systematic shutdown can lead to the failure of the HDD and subsequent replacement.
- If the laptop is clogged with dust, this will lead to an increase in the temperature of the processor, video card and internal temperature of the laptop due to the fact that the cooling system is not working at full capacity. In turn, due to the increase in temperature, any part of the laptop can fail.
- Sudden shutdown of the laptop can cause a black screen or blue screen of death.
- If your laptop turns off and does not turn on anymore, the article “Laptop won’t turn on: causes and remedies” describes in great detail common situations and provides actions that can help you.
