One of the questions most frequently asked on the forums is: “Why does the laptop turn itself off?” Indeed, it is not very pleasant when, just yesterday, a properly functioning computer without any apparent reason spontaneously shuts down. And if at the same time the results of important work are lost, then sometimes this is tantamount to a small disaster.
If the owners of personal computers are mentally prepared for such blackouts (after all, there is no battery in such systems), then users of portable solutions, on the contrary, expect the highest reliability from their electronic assistants. However, long-term operation of complex devices without breakdowns is possible only if their preventive maintenance is periodically performed. The problem when the
laptop turns off by itself is most often caused by ignoring this rule.
When purchasing a new laptop computer, consultants at the store must indicate the need to clean its internal components. The frequency depends on the conditions: when working in residential premises (home), prevention should be carried out at least twice a year. But for a computer that often accompanies its owner on trips, the frequency of revision of components increases up to 4 times in 12 months.
So still, why does the laptop turn itself off? If you remove the bottom cover of the case, then inside you can see many electronic components. Some of them heat up significantly during operation, therefore they are equipped with an active system for removing "excess" heat. It is known that ambient air always contains a certain amount of dust. Gradually settling on radiators, it worsens and completely blocks heat transfer. Result - the laptop turns off itself. The solution is simple: turn off the power and remove the battery. After that, carefully unscrew a few screws holding the bottom case cover and remove it. After that, when examining the state of the components, it usually becomes clear why the laptop itself turns off. It is enough to “blow out” all the dust from the syringe with a stream of air, clean the fan blades and radiator grilles.
Other causes are much less common. Sometimes owners of laptop computers are faced with the fact that even after dusting, spontaneous shutdowns do not stop. Moreover, they are random in nature: today the laptop can work stably all day, and tomorrow it will turn off every 5-10 minutes. Such malfunctions are more complex and require a thorough inspection of components and software checks to identify. Before you search the global network for an answer to the question of why the laptop turns off itself, one simple thing to do is 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 life has already been depleted, therefore, malfunctions of the circuits that control the charge may occur.
And, of course, one cannot ignore such a banal reason as a break in 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 condition can be checked with a simple multimeter.
