Causes of laptop breakdowns

From the point of view of a service engineer, a laptop is a combination of rather complex electronic devices connected with each other. A working laptop is just one condition that constantly strives for a broken one for a number of reasons. It makes sense to describe all these reasons so that the user knows about them in advance, which means that he is on the alert.

I. One of the main causes of a laptop breakdown is overheating. The fact is that all the elements of a laptop work comfortably only in a certain temperature range. During operation, the laptop may become so hot that it will not be able to function at the moment. This can be for a number of reasons: the cooling system does not work well, dust has accumulated in the ventilation hole, etc.

In the best case, the laptop just shuts down, but in the worst case it may not turn on anymore. As a preventative measure, you can advise a few tips: be sure to wait until it is completely turned off before placing the laptop in a bag, bag or safe, plus it is undesirable to put the laptop in such a way as to block the air from accessing the ventilation holes (for example, on the bed), and it is also recommended that it be possible clean the radiator.
II. In the work of any laptop there are drops, deformations, thermal effects, therefore, processor chips, memory slots and other details can disconnect on the motherboard. If it happens that the laptop needs to warm up for normal operation, or it functions correctly only when the buttons on the keyboard are pressed, then there is a high probability that there is a microcrack in the motherboard. To avoid this, it is advisable to use special bags for carrying the laptop, and also not to bend it and protect the laptop from pulling the cords connected to it, even by accident.

III. Extremely important is the so-called human factor as the reason for the failure of the laptop. The main tips on this item: it is better to choose a service center very carefully and carefully, without having sufficient knowledge in any case not to repair the laptop yourself. Even if the user took up the breakdown, then you can not use force and be sure to disconnect the battery!

IV. If any external device is connected to the laptop, which can be a USB mouse, TV, amplifier, etc., that is, the probability of a potential difference is to burn the laptop. To prevent this from happening, you should power the laptop and external devices through one surge protector, connect devices to a turned-on and working laptop, and, if possible, use USB hubs.

V. Often various kinds of liquids are spilled on the laptop due to the fact that its mobility allows the user some freedom in their own actions, such as eating and drinking liquids behind the laptop. It happens that even one drop that fell into the weak spot of a laptop is much more dangerous than a whole spilled glass. Sugar-containing drinks are especially dangerous for a laptop, because after drying they cause jamming of mechanisms. So, to get rid of them it is necessary that this moment comes. If the laptop is flooded, then you must first disconnect the power plug, battery and let the liquid drain into the towel, while avoiding flooding the screen. In no case should you immediately disassemble the laptop, dry it with a hairdryer or rinse with alcohol, you must wait until the battery and power are completely dry (at least 2 days), and then contact the service center.

VI. It happens that a situation arises when the user reverses the polarity on the power supply. But this is only possible when using universal power supplies with removable tips. The protection against this, in fact, is one: it is necessary to use the original power adapter, it is impossible to confuse the polarity in them.

VII. A broken screen is also one of the frequent laptop failures. In this case, the matrix of the screen itself fails, although in order to damage it pretty much, you need to make some effort, but the item left in the laptop will do it for the user (for example, a pen or pencil). In the event of this breakdown, the entire matrix is ​​usually replaced, which is an expensive repair, so when handling a laptop, carefully monitor the absence of foreign objects when closing its lid, and also keep the laptop out of the reach of pets, they also like to walk on the keyboard or lie down on the laptop cover.

This is only part of the most common laptop failures among most users. There are situations when the user takes all preventive measures, but the laptop still breaks down, you should not rack your brains again because of this, but immediately worry about the repair issue. In general, inexperienced users are strongly discouraged from repairing themselves; you should always contact service centers.
