Nowadays, almost everyone has a personal computer at home. Definitely, each person uses it at his own discretion - someone likes to sit and visit various Internet resources, including social media, someone plays games on a computer, and for others a PC is a means of earning money. Every user of this device knows that it is necessary to periodically look inside the system case and clean it of accumulated dust. This dust gets there thanks to the cooling system, which allows you to keep the temperature inside the system unit normal. The dust accumulated there tends to contaminate the fans, which leads to the thickening of the oil on the moving axis and these fans begin to spin more and more slowly.

Many people have a laptop, which in terms of functionality is indistinguishable from a personal computer. This computer is made using all-in-one technology in a miniature case. Do not think that this device does not need to be monitored and maintained, cleaned of dust and the like. Laptops love cleanliness and well-groomed just like a personal computer. Therefore, it is necessary to disassemble it every six months and clean it of accumulated dirt and dust.

Many people wonder how to disassemble a laptop. acer aspire, hp pavilion? The answer is very simple - unscrew all the bolts and open it. But everything is not done that easily. There is a possibility of damaging some parts, therefore, in this topic we will talk about how easy it is to disassemble a laptop.

We take our dirty device, which you want to disassemble for subsequent cleaning, and turn it upside down. Basically, there are various mounts for devices, such as HDD, optical drive and much more. There is also a special compartment for replacement random access memory and WiFi module.

Filming battery, unscrew absolutely all the bolts. Please note that the bolts may also be on the battery compartment. Therefore, if the lid cannot be opened freely, then look carefully at where you forgot to unscrew the bolt.

Before removing the laptop cover, pay attention to the devices that need to be removed first. This will be a hard drive, optical drive. The hard drive is removed by sliding. It has a special grip tape on it. You slide the hard drive and it detaches from the laptop.

Needs to be pulled out optical drive, which is also removable. Sometimes it can be easily removed by unscrewing a special screw on the bottom of the laptop, but on some models there is a double-sided mount, that is, the drive is fixed on the keyboard side. If you can't easily release the drive from your PC, don't rush.

How to disassemble asus laptop, dell, toshiba, if dust has accumulated? The next step consists of disconnecting all the cables that connect to the back. It is necessary to remove various visible cables and cables, mainly the cooler cable and cables wireless communication WiFi. Be sure to disconnect the WiFi cable, as it is located along the display matrix.

So, having disconnected all the cables and cables that are there, you can remove the main part, which is a means of cooling the processor - the cooler. Often, over time the laptop is used, the lower part under the processor begins to heat up more and more - this indicates that the cooler has become weaker or a lot of dust has accumulated on its body, which does not allow air to enter the special exhaust slots.

Cleaning the cooler alone is not enough, so it is necessary to clean the entire cooling system - the radiator, its grids, as well as the radiator mounting on the processor. Be careful when removing the heatsink from the processor - unscrew the four screws and apply a little force to move the heatsink itself. A little effort is necessary because the old thermal paste may have dried out and it needs to be replaced with fresh one, which can again restore heat transfer to the radiator.

Many people are interested in how to disassemble a laptop keyboard? Now, after the above procedure, you can turn the laptop over to its working position and begin removing the keyboard. Typically, the keyboard is attached to the case with special latches, and you can remove it by picking up the tab. If you don't find any protrusions, then your keyboard is most likely bolted under a special plastic surround. You must first remove this trim and unscrew the keyboard. After this it can be raised.

Now you need to disconnect all cables visible under the keyboard. It is imperative, first of all, to remove the keyboard cable itself, there is a risk of damaging it, so the keyboard must not be lifted immediately, but some part where you can safely remove the cable. All cables on the laptop are removed from the special mount by lifting the latch up or moving it to the side.

How to disassemble a laptop and clean it? There are very few operations left to disassemble the laptop. Now that the main closing elements have been removed, it is now necessary to remove the display. To do this, you need to look at where the cables from the matrix come from. Some laptop models have a special cover on the side, under which there are two cables from the matrix - one cable is responsible for supplying a signal to the matrix itself, and the second cable is responsible for backlighting the display itself. They need to be disconnected from the motherboard.

After these cables have been removed, you can begin to unscrew the covers that are connected to the display axis, and then under the covers, unscrew the remaining fastening bolts that strongly press the display to the axis.

Now you can carefully remove the cover with the display from the main part. If separating two parts from each other is difficult, do not make special efforts. You need to look carefully to see if there are any unscrewed screws left. Otherwise, you may damage the lid's axial rotation mechanism. In some laptop models there are no more bolts under the cover - the case is secured with latches. This model has bolts, which means you need to unscrew them.

So, we move on to the point - how to properly disassemble a laptop. After the above procedures, you can safely remove the top cover of the laptop. As mentioned earlier, there are latches on this housing, and in order to touch them and disconnect the upper housing from the lower one, you need to use an amateur radio spatula or you can use a screwdriver with a narrow end.

Now you need to remove the motherboard from the bottom of the case. First, take a closer look at the motherboard. You should notice all the screws on it and unscrew them. Next, look closely at the remaining connected cables. This may be a loop from the connected speakers and should be disconnected. On some models, external interfaces can be made separately and connected to motherboard through the loop. They should also be disabled. After all this, carefully remove the motherboard from the case.

Many people are interested in how to disassemble a laptop battery? There is no need to disassemble the laptop battery, and you cannot repair it. If you feel that your battery no longer holds the laptop as before, this means that some battery cells have exhausted their performance, and replacing these cells will not be so easy, because you can damage the battery case, which will then make it impossible to install it in the laptop. In this case, it is necessary to completely replace the battery on the laptop, and you need to look for exactly the same battery or order it from the manufacturer.

Now that the main part is disassembled, you can begin disassembling the display case. To disassemble the case, you need to remove special rubber plugs that serve as feet between the main body and the display. We carefully pull them out and see the bolts there. We unscrew the bolts and use an amateur radio spatula or a narrow screwdriver to run along the two display housings to release the latches.

With the display cover removed, you now need to detach the display itself from the bottom cover. The matrix is ​​secured with several bolts around the perimeter. After unscrewing these bolts, you can see the inverter under the matrix.

Now, before removing the matrix, you need to disconnect the cable.

The disassembly of the laptop has come to an end. Now you can safely clean each part of the laptop individually. From the plastic case you can remove the electronic elements remaining on it, such as connectors, speakers and many others. After freeing the housing from electronic components, this housing can be washed with soap and warm water.

How to disassemble a laptop cooler and why is it necessary? Most often, the cooler may begin to lose airflow speed and then it is necessary to disassemble it. It is worth considering that not all cooler models can be disassembled.

Some cannot be taken apart at all without breaking it. Only replacement is required here. Those coolers that are disassembled have a hole on the back side behind the sticker, along the axis of which there is a special fastening plastic that holds the axis itself and does not allow the blades with the magnet to fall out of the coil. This plastic can be pulled out with a needle and then the blades themselves can be removed. After cleaning the axle and the blade itself, it is necessary to lubricate the axle with machine oil and reinstall it on the reel. Then you need to put the mounting plastic in place so that it holds the magnet with the blades. If cleaning and lubricating the cooler does not help achieve good results, then the cooler requires complete replacement.

Overheat- one of the three most common “ordinary” problems of all laptops. It occurs due to the fact that the cooling system of the laptop becomes clogged with dust over time, preventing hot air from escaping from the case.

If your laptop, some time after turning it on, begins to get very hot, make noise, slow down, or even turn off abruptly - all these are signs that you urgently need to clean your laptop from dust and change thermal paste.

You can contact a computer service, or you can try preventive measures on one's own.

All you need for this is a couple of simple, available tools, and a certain amount of accuracy and attentiveness. Well, some kind of algorithm for disassembling a laptop, which I will explain to you in this article on my computer blog.

Overheating begins to appear after 1-5 years of using a laptop, depending on the model and conditions of use. But, sooner or later, it will come, because over time, a layer of cosmic dust slowly but surely accumulates on the laptop fan.

I'll try to make my own subjective TOP Hottest laptop models:

1. HP, especially models Dv6,G7
2. ASUS
3. ACER
4. SONY
5. LENOVO
6. SAMSUNG
7. DELL
8. TOSHIBA

I have already written an article about that, as well as how fast and free.

We will assume that you have already An overheating problem was diagnosed. That is, they did a temperature test and found out that under load the temperature of the processor and video card of your laptop rises to 90 degrees or more.

But this was all theory and diagnostics. Now we will get down to practice and actual repairs - disassembling and cleaning the laptop from dust with your own hands.

Disassembling a laptop- not such a simple task as it might seem at first glance to a person who has never “opened” his laptop.

If in most system units, to access the “internals” you need to unscrew 2 screws and slide the lid, then in laptops everything is much more complicated.

There are many laptop manufacturers, each with hundreds of different models, and they are all understood differently. Somewhere you just need to remove the bottom cover. For example, this is exactly the case with . And somewhere, in order to get to the motherboard and remove the cooling system for cleaning and replacing thermal paste, you need to completely disassemble the laptop case, “down to the bolt.”

But general algorithm for disassembling a laptop, as a rule, is always the same. In short, you need to unscrew all the screws, disconnect all the cables, connectors, and open all the latches.

How to independently disassemble any laptop and clean it from dust - universal instructions.

Below I have drawn a laptop device with all the details indicated, so that it would be easier for you to navigate when reading this article.

1. Disconnect the battery

First of all, always disconnect the battery. Disassembling a laptop under voltage can ruin your laptop by accidentally dropping a bolt onto the motherboard. Therefore, the first thing we do is take it out.

On some laptops, the battery is located inside the case, such as. Before turning it off, be doubly careful not to short-circuit anything.

2. Unscrew all visible bolts on the bottom.

Pay attention to their length and thickness. If they are the same, you don’t have to worry. If some come across longer/shorter, we remember/sketch where they were twisted.

3. Remove all the caps on the bottom, and unscrew all the bolts under them

We remove all the small covers on the bottom of the laptop (RAM, hard drive), unscrew all the screws, put them in the next pile. Disconnect all connectors, if any.

You may not have such caps; the bottom of the body may be solid. Don't be alarmed - go to step 5.

4. Disconnect the Wi-Fi module, hard drive, RAM, DVD.

To disable the Wi-Fi module, first remove the 2 antennas from it by pulling them perpendicular to the module. Remember where it was. Then unscrew the bolt securing it and pull the module out of the slot.

Having unscrewed the hard drive, we look at how it is connected. You can remove it by either moving it away from the connector, or by disconnecting the flexible wiring by pulling it.

As a rule, it is not necessary to remove RAM. But you can remove it and clean its contacts with an eraser.

At this stage, you can most often remove the DVD-ROM by slowly pulling on it.

The removable keyboard is easy to distinguish - it looks like a “block” keyboard, i.e. does not form one whole with the rest of the body.

If you are sure that your keyboard is sewn into the upper part of the laptop case (Sony, ASUS 500 series), go to step 8.

6. If the keyboard is removable, remove it.

Don't forget that there is a connection from the keyboard to the laptop motherboard. plume, so after removing it, do not rush to pull it, but first lift and disconnect this cable.

More often for removing the keyboard you need to carefully pry it off with a pick or spatula, and open all the latches around the perimeter.

It happens that before this you need to first remove panel above or under the keyboard.

On some laptops, another unpleasant surprise may await you - an additional keyboard held on by glue. In this case, carefully pry it up with a ruler/spatula/screwdriver, and, gradually lifting it, peel it off.

7. Unscrew all visible bolts under the keyboard, remove all cables and connectors

There are several main types of loops. They all unfasten differently. Some rise, some lift, some stretch.

I will try to systematize them in one of the following articles on the site.

Sometimes at this point you will need to pull long wires from the wi-fi adapter through the case.

8. Carefully “open” the laptop from the side around the perimeter and remove the top cover

For me, the most convenient way to do this is to use a guitar pick, preferably thicker - 0.8-1 mm.

Also, sometimes a spatula helps:

Having walked around the perimeter with a pick and unclipped all the latches, we carefully try to lift the lid. If it doesn’t work, check again that all the screws are unscrewed. If it still doesn’t work, check it again.

No need to use force! And an unscrewed screw often turns out to be imperceptibly recessed into the case, or hidden under a rubber stand at the bottom of the laptop.

The motherboard can be attached either to the bottom of the laptop case (most often) or to the top (this is what they do Sony Vaio). Be careful and take your time.

9. Unscrew the remaining screws and disconnect the connectors, remove the motherboard

We look at which cables go to the motherboard and pull them all out.

Sometimes, in order to remove the motherboard, you have to completely unscrew and remove the top part of the laptop with the screen.

10. Remove the cooling system from the board

The screws on the radiator are usually marked with numbers - we unscrew and tighten them in the order of these numbers, so as not to accidentally damage the chip by misalignment.

We work very carefully here - a screwdriver can easily slip and knock down some element on the motherboard.

Having unscrewed all the bolts, carefully pry up the cooling system; if it doesn’t work, you can turn it a little in its plane. We try not to tear the thermal rubber bands, if any.

11. Disassemble and clean the laptop fan from dust

Actually this is the most important stage laptop disassembly. Right now, in fact, “cleaning the laptop from dust” will take place.

Usually, to disassemble the cooling system, you need to unscrew several small screws on it, and tear off a piece of fabric/adhesive tape, “turning” the fan outward.

We see dust accumulated on the radiator grille - remove it with a brush and blow it out. Congratulations! The laptop has been cleaned) But that's not all.

12. Remove the old one and apply new thermal paste

We remove the old thermal paste from the places where it was, on the chips on the motherboard, and on the cooling system. You can remove thermal paste with a dry cloth and cotton swabs. If you have them, you can soak them in alcohol and take them internally at the same time :)

Often, instead of thermal paste, you can see thermal pads. It is very desirable if they remain intact - it is quite difficult to find them on sale, only to order. If this rubber band is severely torn, most likely it is already “non-working”, you will have to look for it and change it. Or spread a layer of thermal paste. But I don't recommend doing this. Change it! Usually thermal pads are placed on elements that do not have a temperature sensor and protection against overheating, and your laptop may suddenly “die”, while showing normal temperature on the processor and video card.

Apply new thermal paste. How to smear? As thin a layer as possible. Thermal paste is needed not to cover the entire surface of the chip, but to smooth out surface irregularities.

I will write a short review about various thermal pastes in one of the following articles on the site.

And in this video On my YouTube channel you can see how to apply thermal paste using the Pavillion G6 laptop as an example.

13. Reassemble in reverse order.

We assemble it in the same way as we disassembled it, carefully checking at each stage that all connectors are in their sockets. In theory, there shouldn’t be any “extra, empty” ones (but there may be some).

It is advisable that there are no extra bolts left, but if there are some left, don’t worry! 😉 The main thing is that the bolts in the hinge area are screwed in - otherwise the laptop will fall apart over time.

14. We do a temperature test - rejoice! 🙂

Thermal paste needs some time to spread evenly under the pressure of the plate. So its maximum effectiveness is achieved after a couple of days of using the laptop.

Tips and tricks when disassembling a laptop yourself

• Collect screws from each stage of disassembly in separate piles - this way you won’t be mistaken about which screw comes from, and you won’t have any left over.
• Use the Internet - almost every or similar laptop model has detailed photos and video disassembly instructions!
• Don’t use force - if something “doesn’t work”, double-check 10 times to make sure you’ve unscrewed everything and turned it off. When in doubt, go online.
• Be careful and careful, take your time.

Results

So, from this article you learned how to disassemble and clean your laptop from dust yourself.

The first time it may be a little difficult, but the second time, I assure you, it will be much easier! After all, the neural connections in your brain will already be established. 😉

Good luck to all! Any questions left - ask! 😉

Disassembling a netbook Asus Eee PC may be needed in the following cases:

1. The netbook gets hot and makes noise - you need to check and replace the thermal interfaces;
2. The date is constantly lost and the netbook reports errors - replace the CMOS memory battery;
3. the device does not detect the HDD, the hard drive fails on the netbook;
4. other problems with contacts and cables - disassemble, check contacts, if cables need to be replaced;
5. with another, including complex, netbook.

Despite the fact that this netbook is easy to disassemble at first glance (all 4 screws are visible from the bottom of the case), you still have to try a little.

It is necessary to disassemble carefully, following a certain sequence. Otherwise, the integrity of the case may be damaged, chips, deformation, or complete failure of the device.

Start of disassembly

We begin disassembly for subsequent cleaning of dust by disconnecting the battery - this is a standard requirement.

Battery in this device is removed by switching the latches on the bottom side of the case to the unlocked state.

We unscrew the 4 “obvious” bolts and the RAM compartment screw from the bottom cover.

There is another one under the OP cover - unscrew that too. RAM does not need to be removed from the slot.


Next you need to remove the keyboard. The keyboard is held, as in most laptops, by latches located along the top edge and recessed into the space between the keyboard and the case.

The keyboard must be removed by sequentially pushing back the latches and lifting the edge.

In no case do we pull the buttons - we will destroy the keyboard!

Having pulled back the latches, we can find that the keyboard is held quite firmly - there is adhesive tape holding it in place. Carefully pull up, you will hear the characteristic cracking sound of the adhesive tape coming off.

After removal, disconnect the keyboard cable by prying the frame-mount with your fingernail.


Under the keyboard we will find a picture (see below). To completely disassemble the Asus Eee PC, unscrew the screws, including the screw under the yellow warranty sticker, and disconnect the touchpad cable.


After we have removed the screws from the top and bottom of the netbook, we can open the case. We take the corner of the device, and, in the absence of a special tool, carefully push the flaps of the plastic case apart with our nails. They will open with clicks - the case is latched.




Next, opening the case, we turn off the Wi-Fi module, the cables for the screen (the cable may not be the same as in the picture, it doesn’t matter) and the intermodule wire connections.


We remove the motherboard by turning it from left to right to remove it from the VGA and USB output slots.


Next, directly replace the thermal paste in the Asus netbook. And this is a matter of technology. From this position it will be easy to carry out other work - replacing the battery, hard drive, checking cables, and more.

Disassembly is complete.

Assembly is carried out in reverse order.

To avoid static damage to motherboard components when disassembling an Asus Eee PC netbook, it is recommended (in the absence of special bracelets) not to move on surfaces that can generate an electrostatic charge, touch heating radiators, stoves, and so on...

Laptop – convenient mobile device with its own advantages and disadvantages. In order to perform any actions inside the case, for example, replace the hard drive and/or RAM, clean dust, you have to completely or partially dismantle it. Next, let's talk about how to disassemble a laptop at home.

All laptops are disassembled in approximately the same way, that is, they have identical components that require dismantling. In this shot we will be working with a model from Acer. Keep in mind that this operation will immediately void your right to receive warranty service, so if the machine is under warranty, it is better to take it to service center.

The whole procedure basically boils down to unscrewing a large number of mounting screws of different calibers, so it is better to prepare some kind of container for storing them in advance. Even better is a box with several compartments.

Battery

The most important thing to remember when disassembling any laptop is to always disconnect the battery. If this is not done, there is a risk of a short circuit on very sensitive elements of the board. This will inevitably lead to their failure and costly repairs.

Bottom cover

Keyboard and top cover

Motherboard

Cooling system

Disassembly is complete, now you can clean the laptop and cooler from dust and change the thermal paste. Such actions must be performed in case of overheating and related problems associated with it.

A laptop is one of the most convenient and indispensable tools when working. With its help, you can carry out many different operations, from filling out documents and preparing educational materials to watching your favorite movies and listening to music. During long-term use and lack of proper care, a large amount of dust and dirt accumulates on the surface.

Crumbs and other food particles may remain inside the cabinet. Such contamination significantly reduces the performance of the device. In order to carry out proper and complete cleaning of external and internal parts, the laptop needs to be disassembled. The process should be carried out in compliance with several rules and recommendations, described in detail in this article.

This question is one of the most important and relevant for every user. A laptop has a more complex design compared to a desktop computer. If there is a large accumulation of dust or severe overheating of internal parts system unit easy to disassemble and clean. IN portable device The arrangement of components differs from a household appliance, which complicates the process.

In the absence of the necessary skills and knowledge, it is possible to perform an independent autopsy in some cases. For example, the inner surface is clogged with dust or crumbs. In most cases, this leads to a slight overheating of the system and jamming of the keyboard buttons. In this case, you can handle the cleansing process yourself, without the help of specialists.

In most situations, deterioration in performance and regular overheating are associated with the need to replace thermal paste, and sometimes the cooling system. It is quite difficult to cope with such a process on your own without the required skill. The best option will contact the service center. The company's specialists will carry out complete diagnostics, repair work and replacement of necessary parts.

It is recommended to take similar actions in case of accidental damage to the keyboard. During use, this laptop component may be damaged by spilled liquid or fallen food. Many models cannot be cleaned and require complete removal and replacement of buttons. In this case, it is better to entrust the work to professionals.

Note: It should be remembered that if the user independently opens the device casing, the user will lose the warranty from the manufacturer. In the event of accidental damage to any component, the owner will have to pay for replacement and repairs.

Self-disassembly instructions

The process of opening and disassembling is carried out in several stages. First of all, it is necessary to prepare the required tools and materials needed for work.

Preparation:

• laptop;
• crosshead screwdriver;
• napkins;
• small capacity;
• paper;
• marker or pen.

Disassembly must be carried out on a flat, hard surface in a well-lit room. Suitable choice there will be a desk located by the window.

Reference: Please note that the disassembly process on some models may differ from that described. In most cases it depends on the manufacturer. For proper operation, you should carefully read the attached instructions.

At the initial stage, you will need to disconnect the device from the power supply and wait until it turns off completely. Laptop turns over after shutdown rear panel up, placed on the desk. Using a thin Phillips screwdriver, unscrew the bolts holding back cover. The bolts themselves can be placed in a small container prepared in advance. This will help you avoid losing the necessary components.

After removing the back panel, remove the battery. This will help completely de-energize the household appliance. To remove it, you will need to pull the button to the side and carefully remove the battery.

The next step is to extract hard drive and RAM. They are protected by special covers that hold bolts on four (sometimes two) sides. There are a few things to consider when disassembling: important points. Many manufacturers install a kind of protection - rings located on the inside of the lid. This eliminates the possibility of completely unscrewing the bolts. Such protection will protect the owner from accidental loss. In another case, you may encounter the location of the same bolts on both covers. With this design, the hard drive protection elements also hold the RAM cover. In this case, you will need to unscrew all the bolts at once, and the covers are removed at the same time.

Once the retaining components are removed and the covers are removed, you can remove the drive and RAM. The disk should be directed away from the connector with a slight movement, and then carefully pulled up. The RAM is held in place using special latches. To remove it, you will need to carefully move these latches to the sides and pull out the RAM card. After removing the RAM, the memory bar will rise. Its elimination takes place without any obstacles.

Attention: The clamps should be moved apart at the same time.

After removing the memory stick, you can remove the WI-FI module. To do this, carefully pull the contacts out of the retaining grooves and unscrew the bolts. After carrying out the necessary manipulations, the board can be pulled out.

At this point, you can begin to completely remove all the bolts holding both halves of the laptop. Here you should carefully examine the surface of the device, since many elements can be hidden and placed under legs or stickers. Without a complete inspection, elements may become torn off, requiring re-bonding. If the integrity of the nuts, bolts or stickers is damaged, the laptop will automatically be removed from warranty.

The body itself is held in place with special clamps or clothespins. Such latches are not resistant to damage. If done carelessly, it is very easy to break them. To simplify the process, the surface of the case can be slightly pryed with a thin screwdriver, and then open all the clamps.

Important: Care must be taken during operation to avoid possible damage or breakage of the housing.

After disassembling the case, you should remove all the buttons, pull out the contacts and wires. If it is necessary to remove the monitor, both cables are also pulled out. The monitor itself can be mounted on one or two bolts, which can be removed with a screwdriver. Some manufacturers mount the monitor with three bolts located on both sides.

Located under the monitor motherboard, which is also secured with bolts. After unscrewing them, the board can be pulled out. On the back of the board there is a cooling system. The fan is removed after removing the retaining elements.

At the end of the process, it is recommended to thoroughly wipe all components of the disassembled laptop with napkins to remove accumulated dust and dirt.

Basic Safety Precautions

1. It is recommended to record each step of the technological process (disassembly) with a camera or mobile phone. During assembly, many users encounter remaining fastening elements. A photo of each process will help avoid the situation.
2. Paper and pen will help you remember the exact purpose of each bolt. Elements in each case may differ, have different shapes and sizes. Fasteners can be placed by category and their purpose can be labeled.
3. Caution and accuracy are one of the important requirements when disassembling a household device. The covers must not be pulled; the surface itself must be carefully checked for hidden fasteners before removal. If the surface does not lift, the housing should be completely inspected to determine the problem.
4. Plastic parts have a fragile structure. When removing plastic, avoid scratches and cracks. If possible, it is advisable to carry out the work without using a screwdriver.

Conclusion

The laptop is more portable than the usual personal computer. If necessary, you can take the device with you on a trip, to work or study. Over time, the body and inner surface become dirty, which causes a decrease in performance. If you follow all the recommendations and rules, you can disassemble and clean the laptop yourself at home.
