The sick question or Why the laptop itself turns off

One of the questions most frequently asked in the forums is: "Why does the laptop shut itself off?" Indeed, it is not very pleasant, when yesterday a regularly working computer spontaneously turns off for no apparent reason. And if at the same time the results of important work are lost, then sometimes it is equivalent to a small catastrophe. If the owners of personal computers are morally prepared for such trips (because there are no batteries in such systems), users of portable solutions, on the contrary, expect from their electronic assistants of the highest reliability. However, continuous operation of complex devices without breakdowns is possible only if periodic preventive maintenance is performed. The problem, when the laptop turns off by itself, is most often caused by ignoring this rule.

When buying a new laptop computer consultants in the store necessarily indicate the need to perform cleaning of its internal components. Periodicity depends on the conditions: when working in residential premises (home), prevention should be carried out at least twice a year. But for the computer, often accompanying the trips of its owner, the frequency of revision of components is increased to 4 times in 12 months.

So all the same, why does the laptop turn itself off? If you remove the bottom cover of the case, then inside you can see a lot of electronic components. Some of them are heated during operation, therefore they are equipped with a system for actively removing excess heat. It is known that in the ambient air there is always a certain amount of dust. Gradually settling on radiators, it worsens and completely blocks heat exchange. The result is that the laptop turns itself off. The solution is simple: turn off the power and remove the battery. After that, carefully unscrew several screws that hold the bottom cover of the case and remove it. After that, when inspecting the state of the components, it usually becomes clear why the laptop itself turns off. It's enough to blow out all the dust from the syringe, clean the fan blades and grilles.

Other causes are much less common. Sometimes laptop owners are faced with the fact that even after performing dust cleaning, spontaneous shutdowns do not stop. And they are of an accidental nature: today the laptop can work steadily throughout the day, and tomorrow it will shut down every 5-10 minutes. Such faults are more complex and require the identification of a thorough inspection of components and software verification. Before you look at the global network for an answer to the question of why the laptop itself turns off, you should do one simple thing - remove the battery and try to work without it, using power from the mains. The fact is that in relatively old models of such computers, the battery resource has already been developed, so there may be malfunctions in the operation of charge control circuits.

And, of course, you can not ignore such a banal reason, as the breakage of the power cord at the plug. Alas, many users are sloppy, so the cord in this place is constantly bent, the conductors are torn and the contact is broken. The state can be checked with a simple multimeter.
