During operation of a laptop, its electronic components consume electricity, a certain percentage of which is converted into heat. With an increase in the power of the processor and video card, the internal space of the laptop heats up more.
The problem is quite common, so it is important for every laptop owner to know what to do if the laptop gets very hot and turns itself off.
Cooling system device
The system for the heat sink is tightly adjacent to the processor and often to the video chip. It consists of copper tubes that conduct heat to the grill, which is blown by air from the fan and because of this cools down, thereby lowering the temperature of the processor and other nearby components.
The distance between the plates of the cooling grate is extremely small, in this regard, the dust quickly fills the space between the fins, forming a felt that interferes with the passage of air.
The tightness of the copper cooling plate to the processor or video chip is ensured by thermal paste and thermal pad. A thermal pad is an elastic band that adheres tightly to two surfaces. The absence of thermal paste or thermal pad will create an air gap that will reduce the effectiveness of the cooling system.
The processor itself has a flat surface against which a copper cooling plate adjoins. The video chip has the same flat surface.
To ensure that there is no air between the copper plate and the processor, a layer of thermal paste is applied. Thermal paste evens out uneven surfaces on the processor and cooling system for proper fit and excellent heat transfer between them. The thermal pad performs the same function.
Signs of overheating
There are many signs of a significant increase in laptop temperature, depending on which part is subject to overheating, so let's consider the most common:
- the laptop shuts down unexpectedly. The system of protection against excessive high temperatures is responsible for turning it off, therefore, after turning off the computer, it is recommended to turn it on and go into the BIOS, where it is necessary to monitor the temperature parameters of the basic nodes of the laptop, if there is such a possibility;
- periodic freezes and reboots. Most likely, the problem lies in the excessive heating of the video card. An additional factor may be distortion of the picture in gaming applications and the appearance of so-called "artifacts";
- the laptop hums a lot. If the fan is noisy, then you should clean the cooling system or completely replace it;
- hot case. If the laptop case overheats significantly, you should seriously think about eliminating this problem. Often a hot case is combined with loud fans. Cleaning the fan and cooling system completely, if the laptop case gets very hot, is simply necessary - otherwise the device may cause burns;
- if files are slowly being read from the hard drive, or reading data is impossible at all, you need to focus on the hard drive temperature.

Causes and remedies
There are several main reasons for laptop overheating. For each of them, there is an effective method of eliminating the problem when the laptop heats up.
Dust
The most harmless and common reason for laptop overheating is commonplace dust. Over time, it clogs the ventilation grill (in extreme cases, the thickness of the dust layer can reach a centimeter), and significantly complicates the access of cold air through the grill.
Restricting the supply of cold air inside the laptop leads to significant heating of the processor, video card and other components.
Symptoms of this cause are an arbitrary shutdown of the laptop after a certain period of time (usually from 10 to 30 minutes), decreased performance, and fan noise. These signs are especially pronounced in the summer heat.
To eliminate this problem, you should clean the cooling system from dust. An ordinary household vacuum cleaner can be an excellent assistant in this matter.
The thermal paste has dried
Another cause of laptop overheating is thermal paste drying out. This reason is more rare than the previous one, nevertheless, drying of the thermal paste and the arrival of the thermal pad becomes unusable quite often.
In general, liquids transfer heat well, which is why water cooling is more effective than air cooling. As the paste dries over time, the percentage of liquid in it decreases, which means that the cooling efficiency also decreases, although not significantly.
The situation is different with the thermal pad. When the thermal pad wears out over time under high-temperature exposure, it creates compact micro tears, which lead to the fact that its function of transferring heat from the processor to the cooling system is reduced.
Symptoms are similar to dusty air vent. To eliminate these difficulties, it is recommended to replace the thermal grease and thermal pad.
Failure
If, after cleaning and replacing thermal paste, with a processor load of less than 25-40% in office applications, the processor temperature is more than 80C, then most likely there is a failure of the cooling system or board elements. In this case, it is most advisable to take the laptop to a service center.
Cooling systems
Over time, the cooling system no longer provides an acceptable level of cooling. The fans start to spin less, the rotation axes shift. It often happens that the installed cooling system may not provide cooling under significant user loads.
To solve the problems, it is recommended to change the components of the cooling system, or completely change it. The choice of optimal components and their installation is impossible without qualifications and experience, so you need to contact the skilled specialists of the service organization.
Another way out of this overheating situation is to purchase a stand with fans. By placing the laptop on it, you can achieve more significant airflow through the case and, as a result, lower the internal temperature of the laptop.
Board elements
The heat that is generated when the CPU or motherboard chip heats up is transferred to the nearest nodes located on it. Under prolonged and significant exposure to heat, there is a possibility of the formation of microcracks in the soldering points of these components, which leads to a significant release of heat and more rapid wear.
Why overheating is dangerous
With an increase in the amount of dust, the effectiveness of the cooling system is noticeably reduced, the laptop begins to actively warm up, over time it may freeze or even reboot.
But the worst thing is that laptop overheating can cause the following components to break down:
Replacing a video chip or other components costs many times more than prophylactic cleaning of a computer from dust. It should be taken as a rule that if the laptop began to switch spontaneously, it needs to be cleaned of dust.
How to check if a laptop is warming up
To determine which temperature is the maximum for a computer, you can use a special program HWMonitor, which allows you to view all current, as well as maximum and minimum temperatures for a specific period of time. Only the maximum values \u200b\u200bwill be of greatest interest.
Each device has its own temperature limit, certain information can be found on the Internet, something is easy to learn empirically, but usually a combination of several symptoms with clearly overestimated values \u200b\u200bin HWMonitor suggests that the laptop needs cleaning and maintenance.
However, you should be aware that the temperature limit may differ for each model.

Preventive measures
Typically, a laptop gets very hot due to dust and fluff clogging the radiator of the cooling system, so a few simple rules will help to avoid complications associated with its overheating:
- you should not put the laptop on soft surfaces while working, due to the fact that they impede acceptable cooling and fluffs from the soft surface quickly clog the fan;
- do not work in a room with a lot of dust;
- the lion's share of household dust is located at a height of up to 20 cm from the surface, so it is not recommended to work with a laptop on the floor;
- it is necessary to periodically clean the laptop from dust (at least once a year);
- before purchasing a laptop, it is important to determine what it will be used for and to choose the most suitable model for this particular class of tasks. It's important to know that there are no truly gaming laptops.
Just a few trivial rules can protect your laptop from failure or an unplanned trip to a service center.
Overheating of a laptop can cause a lot of headaches, from the well-known blue screens to the loss of important data and even direct damage to the motherboard or processor, and the user does not always understand why the laptop is overheating.
Why does the laptop get warm and what to do about it? Read simple answers and solutions to the problem in this article! Quite often, computer users are faced with a situation when their laptop is very hot, what to do in this case? In addition to the fact that the temperature of the laptop rises greatly and this causes great discomfort for users, the laptop itself can make a lot of noise, slow down and even turn off during operation. What to do in this case and how to fix the problem yourself? Maybe you just need to buy a cooling pad and the problem will be solved?
From what and why does the laptop heat up? The main causes of overheating.
At the first sign of laptop overheating, you should not open Yandex or Google and search for “Laptop overheating, what should I do?” or "The laptop is getting hot, what should I do?" Simple computer tips will not only allow you to eliminate overheating of your laptop, but also make your computer run much faster and smoother.
All electronic components in a laptop consume large amounts of electricity. It is also known from the school physics course that part of the electricity is converted into heat. Of course, the more powerful the processor and video card of the laptop, the more it will heat up. Modern laptops, made using innovative technologies, as well as with the use of new heat-dissipating components, heat up much less and consume significantly less energy than older models.
There are several types of laptops. So, budget laptops heat up significantly less and consume less power than universal models. At the same time, gaming laptops and super-powerful designer laptops with multiple graphics cards and latest-generation processor are like noisy stoves, especially when playing heavy PC games.
The main causes of overheating:
1.
Dried thermal paste on the processor.
2.
Excessive dustiness of radiators and coolers.
3.
Excessive load on the processor from the software side.
4.
Closed or sealed technological (ventilation) openings in the laptop case.
As for the manufacturers of laptops, it should be noted that "music notes" of any model can warm up. Separately, it is worth highlighting only notebooks "Apple", and, perhaps, "Sony" and "Asus", which, thanks to special heat sink technologies, heat up much less (with the exception of powerful gaming laptops of these brands). Gaming music notes will keep warm even with regular cleaning and a cooling pad under your laptop. If the user does not regularly clean and use the laptop in adverse operating conditions, the life of such a device will not exceed 3 years.
Should the laptop warm up? Is there a threat to the device?
The main electronic components of a laptop that get very hot when the device is running are the graphics card, laptop processor and chipset. The laptop heats up especially when processing large amounts of data. Most often, this happens when running resource-intensive graphics programs, playing the latest video games, when converting FullHD video. In a very short time, laptop temperatures can rise to their maximum values. Further, after heating, through a special heat pipe, heat is transferred to the radiator, as well as to the cooler. These components and "throw" heat outside the laptop.
When buying a new laptop and there is no dust on the radiator, the device itself does not heat up much, since the system itself removes heat well from the surface of the internal components. However, over time, dust and lint accumulate on the radiators of coolers and other elements of the cooling system. They interfere with the release of heat outside the laptop and because of this, the heating of the device can become critical until the emergency power off is triggered. Such shutdown occurs at the highest possible temperatures, as the risk of complete failure of the laptop increases.
As for passive and active laptop stands, they reduce the temperature from 2 to 8 degrees, so the benefits of such devices are highly questionable. It is best to periodically clean and lubricate the cooler system and laptop cooling system.
What is the normal temperature for a laptop?
The temperature of the laptop processor directly depends on the degree of its workload, that is, the more programs are running at a given time, the higher the temperature. Ideally, the processor temperature should not be higher than 105 degrees. At the same time, the optimum temperature of the "probe" is 60 - 80 degrees.
In order to find out the temperature of a laptop, you can use two methods. Firstly, you can go in and see the temperature of the device in the BIOS, or you can find out about the temperature using special programs.
The easiest and fastest way to find out the temperature of the "probe" is to go to the BIOS.
To do this, while the computer starts to boot, you must press the F2 or DEL key on the keyboard. After that, find the "PowerMonitor" menu in the BIOS settings. In this menu, you can find both the processor temperature and the motherboard temperature, as well as other additional information. You can also find out about the temperature of the "probe" using third-party applications. For example, programs, Speccy, and other programs.
What should I do if my laptop is overheating? Eliminate overheating.
If your laptop, processor or video card is overheating, do the following:
First of all, you need to look and make sure if the coolers and vents are clogged with dust or debris. To do this, disassemble the laptop by carefully unscrewing the screws and clean up the dust and dirt that have accumulated on the cooler and laptop cooling system.
Next, you should replace the thermal grease. In order to prevent the computer processor from heating up, a layer of heat-conducting compound (thermal paste) is applied between the heat sink and the processor. Over time, the thermal paste dries out and loses its thermal conductivity. To replace the thermal paste, disassemble the notary and clean the processor from the old thermal paste, then apply a thin layer of the new thermal paste to the processor. This procedure is performed when cleaning the computer from dust.
Council. If, despite cleaning and replacing thermal paste, the cooler and radiator continue to heat up, then either replace the cooler with a more powerful one, or install another cooler for better heat dissipation from the computer. Of course, it is best to entrust the replacement of the cooling system, radiator and cooler to specialists from the service center, and not do it yourself (unless you are an experienced IT specialist).
Cooling the laptop
Keep in mind that the temperature of the "processor" is also influenced by where the laptop is located. Do not place it on a soft surface (bed, rug, chair). Ensure that there is at least 5 cm of free space on the side and back of the laptop. Do not cover the computer with stickers, especially in areas where the cooler is exhausting hot air. Do not use it in high temperature, dusty room or high humidity. Several manufacturers are already starting to produce liquid-cooled notebooks. Perhaps you should also consider purchasing such a model. But, the best option, of course, is to clean the heatsink, or cooler, using a compressor or other source of compressed air, as well as new processor lubricant with thermal grease.
What to do if the laptop heats up and turns off?
In the event that the laptop heats up and turns off after a while, it means that the thermal paste needs to be replaced. You should contact the service center or, after carefully disassembling the laptop yourself, removing the old thermal paste on the processor, apply a new layer. Thermal grease can be purchased at any computer store or computer repair service center.
What to do if the laptop starts to make noise, freeze and reboot. Let's consider the reasons why the laptop gets very hot and freezes, and how to solve this problem.
Why is this happening
The electronic components of a mobile PC consume electrical energy, which is converted into heat. The most powerful components are CPU and. They get hotter. Especially in the latest generation laptops with multiple video cards.
Overheating reasons
- The thermal paste has dried;
- Dust;
- CPU load caused by resource-intensive software.
How to know if the device is warming up
If the temperature rises, the OS automatically increases the speed of the cooler. He starts to make noise. In games or when running "heavy" applications, this is acceptable. But if the fan makes noise afterwards, the reason is poor cooling or dustiness.
When working:
- The device freezes unstable;
- Quadrics and stripes appear on the screen. The reason is overheating or damage to the video card;
- Heating of the case. It can be determined by the keyboard buttons. They get hot.
The laptop is very hot, what to do - determine the temperature
Go to BIOS, find information as in the screenshot. Depending on the version, it is located in the following sections: "Power", "Health" or "Hardware Monitor".
What temperature is considered working
For modern Intel and AMD CPUs, the average values \u200b\u200bare:
- In idle mode 28-40 degrees;
- Under load - 40-62;
- The maximum temperature for the CPU is 67-72.
Go to the official website of your device, look there for the temperatures recommended by the manufacturer.
Specialized software
Remove running software
The laptop is very hot and noisy - clean the cooler
Cleaning is the most effective way to solve the problem. How to clean? Turn off the power to the laptop, remove the battery. 
Remove the DVD by unscrewing the mounting bosses on the back of the case. 
Disconnect the RAM in the same way. They are fixed with brackets. Fold them back to remove. 
Remove the location bar located above the keyboard. If it is difficult to remove it, unscrew the screws. 
Remove the ribbon cable. Lift up the securing tab. 
Remove the keyboard. It is secured with plastic clips (4 to 8). I recommend starting at the top corner. Press on it with a screwdriver and raise the corner. 
The system board will appear. Remove it by unscrewing the bolts. 
We unscrew the screws to detach the motherboard from the case. On its reverse side there is a cooling system with a fan. Remove it by unscrewing the screws that hold it. 
Remove dust with a brush or special balconies with compressed air. Purchase them from a specialist store. Purchase graphite grease to lubricate the fan.
If the cooler is noisy, disassemble, clean and lubricate.
How to do it? Disconnect it from the radiator by unscrewing the screws. 
Peel off the sticker. Remove the flat washer with a small screwdriver or needle. 
Remove and clean the impeller. 
Lubricate the cooler. 
Apply new thermal grease
Thermal paste is a substance that improves heat transfer from the CPU to the heatsink. It dries up in 2-3 years. Get a new one at a computer store. Apply it in an even, even layer. A plastic card is suitable for this. Hit the old substance with a school rubber band. 
The laptop gets very hot when charging
The battery is heating up due to a power controller failure or charger malfunction. How can I check this?
Let's check the operation of the battery:
- Turn off the laptop, unplug the charger;
- Remove the battery;
- Connect the charger, turn on the laptop;
- Work 5-10 minutes;
- If the device does not heat up, then the reason is the battery.
If it continues to heat up, look for the cause in the charger. To do this, measure the voltage with a multimeter. Check the values \u200b\u200bon the device. If it doesn't match, replace it.
The reason is in the power controller
It distributes energy between electronic components. A common cause of a crash in software that is responsible for setting energy saving options. Settings can be changed when installing utilities and third-party software.
Press "Win + R" and write "control". 
Further: 
Pay attention to the surface where the device is installed. If it is on a blanket or fleecy carpet, it makes it difficult for the cold air to flow.
The bolts on the plates may be loose. Heat dissipation from the CPU or video card has become worse. In this case, you will have to reapply the thermal paste.
The laptop gets very hot while playing
If the temperature rises when launching a game or resource-intensive applications, the problem is in the cooling system. Replace it with a new one or purchase a special stand to raise the back of the case. Buy with built-in fans. 
Conclusion
We've looked at what to do if your laptop gets too hot and slows down. A common cause is dust clogging the heatsink and cooler blades. Use the recommendations above to clean your device. Be careful not to damage the plastic clips on the board when disassembling.
Overheating laptops Is the most common problem faced by laptop users.If the causes of overheating are not eliminated in time, the computer may work slowly, and eventually break down altogether.
The article describes the main causes of overheating, how to identify them and the most common methods for solving these problems.
Overheating reasons
1) The most common cause of laptop overheating is dust. As with a desktop computer, a lot of dust accumulates inside a laptop over time. As a result, cooling problems in the laptop are inevitable, leading to overheating.
Dust in the laptop.
2) Soft surfaces on which the laptop is placed. The fact is that on such surfaces, the ventilation holes are blocked on the laptop, which ensure its cooling. Therefore, it is highly advisable to place the laptop on hard surfaces: table, stand, etc.
3) Too heavy applications that heavily load the processor and video card of the mobile device. If you often load your computer with the latest games, it is advisable to have a special cooling pad.
4) Failure of the cooler. You should immediately notice this, because the laptop will not make any noise at all. In addition, it may refuse to boot if the protection system is triggered.
5) The temperature around is too high. For example, if you put your laptop next to a heater. I hope this point does not need a detailed explanation ...
Do not put your laptop next to such a device ...
How to determine if a laptop is overheating?
1) The laptop is making a lot of noise. This is a typical sign of overheating. The cooler inside the case spins faster if the temperature of the laptop's internal components rises. Therefore, if the cooling system for some reason does not work efficiently, then the cooler will constantly work at maximum speeds, which means it will make more noise.
The increased noise level is quite acceptable under heavy load. But if the laptop starts to make noise after turning it on, then something is wrong with the cooling system.
2) Strong heating of the case. Also a characteristic sign of overheating. If the laptop case is warm, this is normal. Another thing is when it's hot - you need to urgently take action. By the way, the heating of the case can be controlled by "hand" - if you are so hot that your hand can't stand it - turn off the laptop. You can also use special programs.
3) Unstable system operation and periodic freezes. But these are inevitable consequences for cooling problems. Although not necessarily the reason for the laptop freezing is due to overheating.
4) Strange streaks or ripples appear on the screen. As a rule, this signals the overheating of the video card or central processor.
5) Some USB or other ports are not working. Severe overheating of the South Bridge of the laptop leads to incorrect operation of the connectors.
6) Spontaneous shutdown or restart of the laptop. When the CPU is too hot, protection is triggered, as a result, the system is rebooted or completely shut down.
Several ways to avoid overheating your laptop
1) In case of serious problems with overheating of the laptop, for example, when the system spontaneously reboots, is unstable or turns off, you need to urgently take action. Since dust is the most common cause of system overheating, you need to start with cleaning.
If you do not know how to clean the laptop, or this procedure did not fix the problem, then contact the service center. Otherwise, constant overheating will inevitably lead to serious damage. Repairs won't be cheap, so it's best to eliminate the threat ahead of time.
2) When overheating is not critical, or the laptop heats up only under increased load, you can take a number of actions yourself.
Where is the laptop during work? On the table, on your lap, on the couch ... Remember, the laptop should not be placed on soft surfaces. Otherwise, the ventilation holes on the bottom of the laptop will close, which inevitably leads to overheating of the system.
3) Some laptops allow you to connect a video card of your choice: built-in or discrete. If the system gets very hot, switch to the integrated graphics card, it generates less heat. The best option is to switch to a discrete card only when working with powerful applications and games.
4) One of the most effective ways to help the cooling system is to place the laptop on a dedicated table or stand with active cooling. Be sure to get a similar device if you haven't already. Coolers built into the stand prevent the laptop from overheating, although they create additional noise.
Laptop Stand with cooling. This thing will help to significantly reduce the heating temperature of the processor and video card and will allow you to play for a long time or work in "heavy" applications.
Remember that constant overheating of the system will damage your laptop over time. Therefore, if you see signs of this problem, fix it as soon as possible.
Overheating is the most common problem faced by owners of portable devices such as a laptop or netbook. Let's try to understand why a laptop can overheat and what to do to extend the life of a computer assistant.
Dirty ventilation openings
In most cases, overheating is caused by insufficient (ineffective) ventilation of the laptop. Each laptop has grill-style vents on the bottom and side, through which cold air is drawn in and warm air is blown out. Thus, heat is removed from the processor, video card and hard drive - the main sources of heat in a laptop. It is clear that with insufficient ventilation, for example, with strong dust, heat dissipation will be unsatisfactory and the laptop will start to overheat. For a quick test of the laptop's ventilation system, place it on a flat, solid surface such as a table and turn on the device. Place your palm close to the air vents (usually on the side) and if a sufficiently strong stream of warm air comes out through them, then the ventilation is fine. If you practically do not feel the movement of air, then the laptop is probably clogged with dust and the fan simply cannot blow out excess heat through the holes blocked by the dust. In this case, you will need to clean your laptop.
It is quite difficult to effectively clean a laptop from dust without disassembling it, but, nevertheless, at home it is quite possible to remove some of the dust and improve the performance of the cooling system. For this you need a compressed air source. In computer stores, you can buy a special can of compressed air, but in extreme cases, a vacuum cleaner with an air blowing function is also suitable. Direct a jet of compressed air directly into the air vents, both the exhaust and the air inlets, where the cooler sucks in air (usually located on the bottom cover of the laptop). This will blow out a significant amount of dust, so take appropriate precautions or carry out this procedure outdoors. Naturally, you won't be able to blow out all the dust, but the main part that interferes with normal ventilation will probably be removed.
Cooling fan failure
The laptop can get very hot for the simple reason that the cooler is completely out of order and stops rotating. In this case, you will not feel the movement of the blown air at all, as well as the characteristic sound of the rotating fan. And the presence of vibration and strong noise from the fan indicates its probable malfunction. The cooler can only be replaced by a service center, it is better not to perform such work without special knowledge and skills on your own. If you do decide to perform this procedure yourself, read the appropriate instructions.
Replacing thermal paste
Often a laptop heats up, and often turns off, due to the degradation of thermal paste under the heatsink for cooling the processor and video card. Thermal grease is a special viscous heat-conducting mixture that serves to fill the micro-gaps between the heating source (for example, the processor surface) and the metal heatsink of the cooler, thereby allowing more efficient heat transfer. If this layer has lost its viscous and heat-conducting properties, has simply dried up, then it no longer fills the gaps, and, therefore, inefficiently transfers heat from the processor to the cooling radiator. As a result, your laptop gets very hot, slows down and may even turn off. In this case, the processor or video card chip is exposed to overheating, the temperature of which rises, but the air blown out at the same time is barely warm.
You can check the temperature of laptop chips using free utilities such as Fan-Speed, CPU-Z, GPU-Z, AIDA64 and others. And if they show a high temperature of the components (above 70 degrees), and the blown out air is slightly warm, then the cause of overheating is thermal paste that has lost its qualities.
Correct operation and preventive maintenance
Another reason for overheating is mechanical blockage of ventilation openings. This is a common mistake of incorrect operation of a laptop, associated with its main advantage - mobility. Thanks to the mobility on a laptop, you can work not only at the table, but also lying on the couch or sitting in an armchair. In this case, very often the ventilation holes are blocked by a soft surface. As a result, the laptop does not cool well and overheats quickly. To eliminate this, you should use a flat stand under it. Even a wide hardcover book will do.
In some cases, the cause of laptop overheating lies in the software area. You should pay attention to those applications, when started, which occurs intense heating. Open the "Task Manager" and see the processor load of various processes. If one or several applications constantly load the processor above 20-30%, then this leads to its intense heating. Here you should do the optimization of processes, disable unused services, defragment the hard disk (if it is an HDD), check the computer for viruses (viruses often overload the processor), etc. Well, if very resource-demanding applications are often used, then you should purchase a special cooling pad for your laptop. There are two or more fans on it, which will cool the entire bottom surface and contribute to more efficient heat dissipation. As a result, working on a laptop will become comfortable, especially in demanding applications and at high temperatures in the room, for example, in summer.
In order to keep the laptop from overheating, it must be properly operated. Do not work on soft surfaces, especially at a table, and do not obstruct ventilation openings. Also, do not place the laptop near heating appliances. It is not recommended to operate in demanding applications for extended periods and at high ambient temperatures without additional cooling. Still, the cooling system of mobile computers is not as efficient as that of a desktop computer. Clean your laptop regularly, at least once a year. Also, monitor the temperature regime of the laptop, checking the temperature of its main components every six months to assess the condition of the thermal paste.
