Cleaning the laptop from dust at home. How to clean a cooler, keyboard on a laptop

It is difficult to argue with the fact that, from the point of view ofperformance, stationary personal computers are more preferable than their mobile counterparts - laptops. The capacious case allows without any special difficulties to place there an effective cooling system capable of dissipating the heat released by the components. Nevertheless, in recent years there has been a clear trend towards the gradual abandonment of average users from personal computers in favor of laptops.

This is caused, in particular, by a decrease in the numberfans of ultramodern games, for their work requiring impressive computing power, as well as the desire to somehow optimize their workplace. So, in an apartment on a place necessary for high-grade system block of a computer table it is possible to put a composition-ikebana. At the same time, compactness has to be "paid": any owner of a portable computing system simply has to know how to clean laptops from dust at home.

Hot temper

Now actively discuss the potential of quantum oreven biological computers that do not emit much heat. However, the reality is that while all mass models are the usual electronic ones. Their work is subject to the relevant laws, among which one of the key is the heating of conductors during the passage of current. To remove heat from the processor and video card, a metal radiator is used, blown by the airflow of the fan. Over time, these elements accumulate dust, which significantly reduces the effectiveness of their work and leads to errors in programs. Periodic disassembly and cleaning of the laptop can prevent such trouble, and sometimes protect the computer from damage due to overheating. This operation can be performed independently. Owners who for any reason can not do this should contact the service centers where they will be provided with the corresponding service - laptop repair. Cleaning, as a rule, is one of the varieties of this procedure.

What will the "doctor" say?

Before you take on a screwdriver, you need to make sure of the timely cleaning. It is easy to determine by indirect evidence.

So, if the laptop is even readingThis article basosito buzzes fan and does not turn it off for a minute; If applications are often closed for no apparent reason; if the hot air blows out all the time from the ventilation grille of the case, and the owner has never heard about how to clean the cooler on the laptop, you can be sure: it's time to do an audit. As you can see, even a schoolboy can put the "diagnosis".

List of tools

Cleaning the laptop from dust at homeIt is impossible without disassembling the case. So first you need to prepare everything you need. This is a set of clock screwdrivers, cotton wool and alcohol. A small syringe, a children's brush for drawing and tweezers are very desirable.

Disassembly rules

Most laptops are dealt with one by one andthe same principle. Unplug the power supply cord and remove the battery. The latch that holds it is located on the bottom of the casing and has a corresponding designation. Usually, to access the battery, you need to move the switch to the side with the image of the open lock, and then use the other one on which the battery is displayed. The power supply must always be removed. Otherwise, cleaning the laptop from dust at home can lead to the failure of the latter due to the closure of the tracks by accidentally falling bolt.

On the bottom there are a number of bolts holding the lid.They need to be carefully unscrewed. The cover is additionally fixed with snap-lock clips, which should be pinched by a flat tip of a small screwdriver. It is important to ensure that the probe does not go deep into the housing to avoid damage to the internal components. We recommend in no case to rush, but to think about each action. Especially if disassembly and cleaning of laptops from dust at home is performed for the first time.

How the components cool down

After removing the cover, you can see the cooling system. In modern portable computers it is represented by several radiators connected by heat pipes.

On one side they converge on the blockheat exchanger, consisting of thin metal plates, air blown fan. The principle of the system is extremely simple: the heat from the hottest components through the heat pipes is transferred to the plates. The fan takes external air through the grate on the bottom (by the way, that's why working with a laptop lying on your knees is not a very good idea). Then, through a special design of the "snail", air is directed to the heat exchange unit and outwardly through the grill from the side or back of the hull (depending on the model). Everything is extremely simple.

How to eliminate pollution

Such an implementation of the "problematic" places has several- these are gratings for intake / discharge of air, a fan with a "snail" and heat dissipating plates. It is on them that dust and household garbage gradually accumulate (sometimes even straw appears), because of which the process of heat removal decreases or ceases altogether. Beginners often ask how to clean the cooler on the laptop. In fact, everything is quite simple.

First of all you need to disconnect the wire from the boardpower supply fan - there is a simple plug-in connection. Then gently unscrew the fan-holding screws (ideally magnetized screwdriver) and remove the entire structure. After that, using a syringe and a brush, you can remove all dirt from the plates by simply blowing them. The same is useful for the whole system of heat pipes. The fan blades are wiped with cotton wool soaked in alcohol. In a word, everything is brought to the state of "recently bought". When installing miniature screws back may require tweezers. The entire operation to remove dust takes no more than 10-15 minutes, if everything is done without haste. In some "neglected" cases, this kind of laptop cleaning can not always help. Replacement of thermal paste is the last argument that can solve all the problems with overheating, which remained after the elimination of dust. The fact is that between radiators and cooled microcircuits there is a special layer designed to improve the process of heat transfer. It is called "thermal paste" and has a complex composition, often including silver. Over time, its heat-conducting properties fall, and its updating is necessary. To do this, you need to prepare a new thermal grease, carefully dismantle the entire cooling system (never peel and carefully remove), remove the remnants of the old interlayer, apply a thin layer of a new layer with a match and put it all in place. The paste itself can be purchased at any computer equipment store for a pittance (from 100 rubles).

By the way, during the cleaning procedure should not beIgnore the keyboard processing. Especially if the keys sink or stick. In most models, each of them can easily be pinched with a screwdriver, taking it off the latch. Then, using cotton wool and alcohol, wipe the seats and the buttons themselves. No service center is required!
