It's hard to argue with the fact that, in terms of performance, stationary personal computers are more preferable than their mobile counterparts - laptops. The roomy case allows you to easily place an effective cooling system there, capable of dissipating the thermal energy emitted 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 number of fans of cutting-edge games that require impressive computing power for their work, as well as by the desire to somehow optimize their workplace. So, in an apartment, in place of the computer desk necessary for a full-fledged system unit, you can put an ikebana composition. At the same time, you have to “pay” for compactness: any owner of a portable computing system simply must know how laptops are cleaned from dust at home.conditions.
Hot temper
The potential of quantum or even biological computers, which do not emit much heat, is now being actively discussed. However, the reality is that so far all mass models are familiar electronic ones. Their work is subject to the relevant laws, among which one of the key ones 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 a fan airflow. Over time, dust accumulates on these elements, which significantly reduces their efficiency and leads to errors in programs. Periodic disassembly and cleaning of the laptop can prevent such troubles, and sometimes protect the computer from damage due to overheating. This operation can be performed independently. Owners who for some reason cannot do this should contact service centers where they will be provided with the appropriate service - laptop repair. Cleansing is usually one of the variations of this procedure.
What the "doctor" would say
Before you take a screwdriver, you need to make sure that the cleaning is timely. This is easy to determine by indirect signs.
So, if a portable computer, even while reading this article, is buzzing in a bass voice with a fan and does not turn it off for a minute; if applications often close for no apparent reason; if hot air escapes from the ventilation grill of the case all the time, and the owner never knows how to clean the cooler on a laptopheard, you can be sure: it's time to audit. As you can see, even a schoolboy can make a “diagnosis”.
List of tools
Cleaning laptops from dust at home is impossible without disassembling the case. Therefore, first you need to prepare everything you need. This is a set of watch screwdrivers, cotton wool and alcohol. A small syringe, a children's paint brush and tweezers are highly recommended.
Disassembly rules
Most laptops are taken apart the same way. Disconnect the power cord and remove the battery. The latch holding it is located on the bottom of the case and has a corresponding designation. Usually, to access the battery, you need to move the switch to the side with the image of an open lock, and then use the other one, which displays the battery. The power supply must always be removed. Otherwise, cleaning laptops from dust at home can lead to the failure of the latter due to the closure of the tracks by an accidentally dropped bolt.
There are a number of bolts on the bottom that hold the cover. They need to be carefully unscrewed. The cover is additionally fastened with latches, which should be pry off with a flat sting of a small screwdriver. In this case, it is important to ensure that the probe does not go deep into the housing in order to avoid damage to internal elements. We recommend that you do not rush in any case, but think over each action. Especially if disassembling and cleaning laptops from dust at home is done for the first time.
How coolcomponents
After removing the cover, you can see the cooling system. In modern laptop computers, it is represented by several radiators connected by heat pipes.
From one side they converge into a heat exchanger unit consisting of thin metal plates blown by fan air. The principle of operation of the system is extremely simple: heat from the hottest components is transferred through heat pipes to the plates. The fan draws outside air through the grate on the bottom (by the way, this is why working with a laptop lying on your knees is not a very good idea). Then, through a special design of the "snail", the air is directed to the heat exchange unit and is discharged outside through the grill on the side or rear side of the housing (depending on the model). Everything is extremely simple.
How to remove pollution
This implementation has several "problem" places - these are air intake / exhaust grilles, a fan with a "snail" and heat-dissipating plates. It is on them that dust and household garbage gradually accumulate (sometimes even straw is found), due to which the process of heat removal decreases or even stops. Beginners often ask how to clean the cooler on a laptop. It's actually quite simple.
First of all, you need to disconnect the fan power wire from the board - there is a simple detachable connection. Next, carefully unscrew the screws holding the fan (ideally with a magnetized screwdriver) and remove the entireconstruction. After that, using a syringe and a brush, you can remove all dirt from the plates by simply blowing them. It is useful to do the same for the entire heat pipe system. The fan blades are wiped with a cotton swab dipped in alcohol. In a word, everything is brought to the state of "recently bought." Tweezers may be required when reinstalling miniature screws. The entire operation to eliminate dust takes no more than 10-15 minutes, if everything is done without haste. In some "neglected" cases, such cleaning of the laptop may not always help. Replacing the thermal paste is the last argument that can solve all the overheating problems that remain after removing the dust. The fact is that between the heatsinks and the cooled microcircuits there is a special layer designed to improve the heat transfer process. It is called "thermal paste" and has a complex composition, often including silver. Over time, its heat-conducting properties fall, and it needs to be updated. To do this, you need to prepare a new thermal paste, carefully dismantle the entire cooling system (in no case tear it off, but carefully remove it), remove the remnants of the old layer, apply a thin layer of a new one with a match and put everything in place. The paste itself can be purchased at any computer hardware store for mere pennies (from 100 rubles).
By the way, during the cleaning procedure, do not ignore the processing of the keyboard. Especially if the keys sink or stick. In most models, each of them can easily be pry off with a screwdriver, removing it from the latch. Then, with the help of cotton wool and alcohol,wipe the seats and the buttons themselves. No service center required!
