Why is the laptop turned off?

A laptop, like any other technology, requires careful attitude and constant care. At the slightest suspicion of breakage, it should be attributed to diagnose and repair the service center. One of the dangerous symptoms is self-shutdown computer. The reasons why the laptop turns itself off may be several.

Why the laptop is turned off: reasons

Consider the most common causes and solutions.

CPU overheated

This is the most common "disease" of laptops. To protect the computer from overheating, the BIOS has a protection feature that turns it off when the temperature exceeds the limit. In the latest models of processors built their own protection, which resets the frequency of the processor, without turning off the laptop (throttling). You can check whether the laptop is overheating or trotting is running, you can use the Everest program. In this case, it is advisable to clean the laptop, replace the thermal paste. If cold air escapes from the cooler at an elevated temperature of the processor, the problem is in the cooling system breaking.

Overheating video card

The most likely cause is the use of a laptop on a soft fleecy surface (carpet, sofa, lap). Dust and fine fibers are clogged in the ventilation holes on the bottom of the notebook and interfere with the normal movement of air flow. As a result, the video card overheats and the laptop shuts down. Usually overheating occurs when performing demanding tasks (games, watching high-quality video).

Battery failure

If the laptop does not turn on or is disconnected while working from the battery or from the mains, the problem is the breakdown of the battery or the charge level controller. But before you carry it in for repair, you can check the serviceability of the contacts on the battery.

Hard drive problems

If you turn off the computer before the creaking, gnashing and other suspicious sounds, there is a possibility of failure of the hard drive. Owners of old laptops with a lifetime of more than 5 years are faced with such a problem. In order not to lose the information stored on the disk, you should immediately transfer it to external media.

Crack on the motherboard

If the laptop was subjected to shocks or other mechanical impacts, it was actively and continuously used, a crack could form on the motherboard. This problem may not appear immediately, but over time as the crack increases during operation.

Failure or incorrect BIOS firmware

Hardware failure may occur due to mechanical impact (shock or liquid ingress). Software crashes may occur due to improper flashing.

Connector oxidation

It may occur due to non-compliance with the temperature mode of operation of the laptop, turning on after a sudden change in temperature. In this case, only the soldering of the oxidized connector will help.


Some antiviruses use excessive system resources when scanning. To remove the problem, you should cancel the extra functions in the settings and set the scanning process on request. Running incompatible programs can also cause computer shutdowns if they appear after installing a new program. The system may be infected with a virus.In this case, it will need to be cleaned or reinstalled.
