Why is the laptop turned off and what should I do?

It happens that the laptop suddenly turns off during operation. Why is the laptop turned off and what should I do?

The reasons for turning off the laptop can be hardware and software. It can be turned off when running on battery power and when working from electricity.

If you turn off the laptop while it is running on battery power, then most likely the cause is in the latter's fault, and you should replace it.

The main reasons for self-shutdown of the laptop running from the mains are: equipment overheating, motherboard crack, connector oxidation, poor contact soldering.

In 90% of cases the laptop is turned off because ofoverheating. A working laptop gives off a lot of heat, especially during resource-intensive games and when watching movies of high quality. As you know, the cooling system is not the strongest place in the laptop, in the case of which there is simply no space for powerful fans. Overheating can occur due to malfunctioning ventilation. The laptop overheats if the air exchange holes are clogged with dust or closed during operation by foreign objects. Ventilation holes are usually closed when working on soft surfaces: a blanket, a pillow, a carpet.

Determine overheating very easily - the laptop is toohot, ventilation rustles more than usual, constant "braking" and "squares" in games, the CPU utilization is close to 100%. When this mark is reached, the overheat protection system is triggered and the notebook is turned off. Constant overheating of the notebook entails the failure of its various parts. Most often flakes from the video chip card.

In case of overheating, it may be necessary to repair the cooling system: dust removal, thermal paste replacement, fan cleaning and lubrication. If the fan is defective, it must be replaced.

Another reason that turns off the laptop -crack on the motherboard. This is typical for old laptops or in the case of its active operation and non-lean relationship. Such cracks on the motherboard may occur if the laptop is dropped or hit. Microcracks may not immediately affect the operation of the equipment, but as a result of unavoidable heating and cooling, they will become wider and the laptop will shut down. The problem is solved by replacing the motherboard. Replacement of the motherboard is quite expensive, which is not always justified.

Turns off the laptop due to the oxidation of someconnector. This defect occurs during improper operation of the equipment. For example, use at unacceptable temperatures or the inclusion in a warm room of a laptop just brought from the cold. To solve the problem, you have to solder or replace the connector.

And one more possible reason for turning off the laptop is poor-quality contacts. Such a defect occurs on cheap models and laptops, which have long and been actively exploited.

The laptop also turns off for software reasons.

This can happen because of antiviruses thatconsume a lot of resources, especially when scanning files or disks, loading the processor by 100%. The problem is solved by disabling some of the antivirus functions and enabling scanning only on demand.

The next software cause is malicious andincorrect programs, leading to a "hang", which loads the processor by 100%. This protects against overheating and the notebook turns off. It is required to get rid of viruses and to remove incorrectly written programs.

The reason for turning off the laptop may be an operating system error, incompatible programs, errors in programs.

The spontaneous switching-off of the laptop happens at malfunction of the built in and outwardly connected equipment.
