The laptop is actually a full-fledged desktop computer, which was packaged in a compact case the size of a keyboard. Therefore, it is not surprising that sometimes laptop users encounter .

In this article we will look at a number of reasons that can lead to excessive heating of a laptop and tell you why this happens and what can be done about it.

Reason #1: The laptop is placed on a soft surface.

Placing a laptop on a soft surface, such as a sofa or pillow, inevitably leads to strong heating of its components. The problem is that placing the laptop this way leads to the fact that its ventilation holes are closed and the cooling system cannot suck in cool air or remove already heated air.

This is especially true if the laptop is initially poorly cooled, for example, it is clogged with dust. Or if the laptop is used under heavy load. In such situations, placing the laptop on a soft surface becomes the last straw, and it begins to reboot from overheating.

Solving this problem is very simple. If you want to use your laptop while sitting on the couch or in bed, then find some hard surface that you can use as a stand or table for your laptop. If you don’t have anything suitable at hand, then you can buy such a table. They can be found on the Internet by searching for “laptop table.”

To check what is causing CPU load » and sort running processes by CPU load. If the list contains processes unknown to you that will constantly load the processor, then this is a reason to install an antivirus and check your computer. If you already have an antivirus, then try replacing it with another one.

Reason #3: The laptop cooling system is clogged with dust or faulty.

If you position your laptop correctly and you have checked it for viruses, but it still gets too hot, then the problem may be that the laptop's cooling system is clogged with dust. This usually affects laptops that are 1 year or older. In order to properly remove dust from the cooling system, the laptop must be completely disassembled. This procedure is not easy, so it is better not to do it on your own and contact a service center. Otherwise, laptop repair can be much more expensive.

Also, excessive heating of the laptop may be a symptom of a breakdown in the cooling system. The most common problems are dry thermal paste, a broken cooler, or a faulty heat pipe. Such a problem can only be detected and corrected by completely disassembling the laptop at a service center.

Reason #4: The laptop's cooling system simply can't handle it.

If you constantly use your laptop under high load, for example, playing games on it computer games for many hours in a row, then strong heating can occur even if the cooling system is fully operational. This is because some laptops are simply not designed to handle such intense workloads.

This problem can only be solved by improving the cooling of the laptop using a special stand with fans. These stands connect to the laptop connector and use fans to force cool air into the laptop's vents. This solution is quite effective and can immediately significantly reduce the temperature of laptop components. But, you will have to put up with increased noise levels.

If programs begin to slow down and freeze, the cooler begins to make noise, and the laptop itself constantly turns off, then most likely it has overheated. The most common cause of this problem is the presence of dust that covers the cooling and ventilation system, due to which it cannot function properly. Cold air stops flowing in optimal quantities, which causes overheating of key parts. You can get rid of this problem by cleaning.

Among the main components of a laptop that constantly overheat are the video card, CPU and chipset. Maximum heating becomes noticeable when serious and massive data is processed. This usually happens during the operation of graphic applications, launching new games, or editing high-resolution videos. In just a couple of minutes, the temperature of the gadget can increase by tens of degrees. After heating, the heat itself must pass into the radiator and cooler system, from where it is “thrown out” outside the device.

When a new device is purchased and there is no dust in the heatsink, the device will not heat up very much, since the system does an excellent job of dissipating heat from key components. However, after a certain period, dust begins to accumulate on cooler radiators and other elements, which makes it difficult to release heat outside the laptop. Often the heating of the gadget becomes critical and an urgent power outage occurs. It happens when the temperature is too high, since there is a high chance of permanent breakdown of the laptop.

Important! To prevent this from happening, it is recommended to clean your devices regularly or at least purchase passive or active cooling pads that help reduce the temperature by several degrees.

Why does my laptop start to heat up? Main reasons and problems

To solve the problem described above, its root causes must be identified. We are talking about:

• shortcomings of manufacturers involved in the design of the cooling system. This usually applies to cheap models; employees of new brands do not conduct test work in order to reduce the cost of the device;
• contamination of components such as cooler, radiator. Often, dust penetrates the radiator grille and covers the main components, which is why cooled air can no longer pass through. Sometimes, after a layer has formed, the fan stops rotating quickly;
• violation of the insulating layer. As a result of prolonged operation of the laptop, the thermoplastic dries out, as a result, thermal conductivity deteriorates, which provokes overheating;
• failure to comply with basic operating requirements. In some situations, users themselves are to blame for overheating of the gadget. The design of the laptop case implies the presence of technological holes into which cold air enters. The user may not notice them and constantly block them.

What are the signs that your laptop is overheating?

The following signs will help you understand that your laptop is starting to get very hot:

• actively running fan while gaming or watching media. The laptop may turn off spontaneously, especially when resource-intensive programs are launched, such as games and a video player. After cooling down, the laptop turns on again;
• occur frequently. Of course, this is not always directly related to overheating. Freezes can occur due to software errors, driver failures and OS problems;
• Games periodically lag. The user does not feel “smooth” while playing new games; after 30 minutes to an hour, the laptop turns off spontaneously. The thing is that the processor and graphics card They cannot cope with too high a temperature and cannot fully process the image.

What to do if your laptop gets very hot and makes noise?

If a user is faced with the problem of laptop overheating, he should take a number of actions to avoid this problem.

Removing unnecessary programs from startup

So, first you should get rid of unnecessary and unnecessary programs that are in startup (launched in automatic mode after the laptop turns on) to reduce system load.

You can manage automatically downloaded programs using the MSConfig utility - it allows you to see which utilities are launched along with operating system, remove them and so on. Moreover, MSConfig is used not only for this purpose, so you should be extremely careful when using it. For launch MSConfig follows:

Buying a Cooling Pad

Additionally, it is recommended to purchase a cooling pad. Inside, it includes several fans that serve to cool the case. It is better to buy a model with several fans at once, since the main components such as the processor and video card are located on the edge of the device, next to the ventilation holes - if there is one fan, then it will be located in the center of the stand, but if there are at least two of them, then one of them will be just as close as possible to the place where the heat is generated. A cooling pad will have a significant effect, but it is still worth remembering that at some point you will need to clean the laptop from dust, even if you use the stand. Many people lift the laptop and place it on books so that the ventilation holes are open. This also helps, but not very much.

Removing processes that load the CPU

Additionally, you should consider reducing the processor power by several tens of percent. This will also affect the heating of the graphics component, since their operation is interconnected with each other.

Cleaning the laptop cooling system from clogging

Cleaning the laptop cooling system from - the most effective way cope with the problem of heating the device. To do this you will need to perform a number of actions, namely:

1. Turn off the power to the laptop and remove the battery.

   

2. Remove the DVD drive - to do this, just unscrew one (two) screws on the back of the case.

   

3. Disassemble the laptop, disconnect the main HDD and RAM in the same way (they are secured using special brackets, which must first be bent).

   

4. Separate the bar at the location of the speakers above the keyboard. If you have difficulty removing the bar, then you first need to unscrew the screws.

   

5. Remove the cable - to do this, pull the fastening tab upwards, after which the cable will be removed.

   

6. Disassemble the keyboard. It is secured using the same plastic latches - their number varies from 4 to 8. It is recommended to first remove the upper corner latch - just press on it with a flat-head screwdriver and pry off the corner. You can also unclip other fasteners using the same method.

   

7. The system board will become visible - in this case it is also necessary to unscrew the screws to disconnect it from the case.

   

8. On the reverse side motherboard The cooling system and fan are located - they should also be removed by unscrewing the main fasteners.

   

9. Dust is removed from the slats using a special brush or compressed air. To clean the fan you will need to get graphite lubricant.

You need to determine how well the cooler rotates. If the laptop was noisy during operation, then this component should be disassembled, cleaned, and lubricated.

Important! Before assembling the laptop, it is highly recommended to apply a layer to the chips. It is better not to use the KPT-8 model, which is in demand today, which has far from the most effective properties. Its thermal conductivity is not effective, and it tends to dry out after a certain period of time.

How to prevent the system from overheating?

To no longer encounter the problem of system overheating, it is enough to follow certain recommendations:

• It is better not to run on a regular basis those applications that require a lot of resources - these are graphics utilities and modern games. Because of them, the CPU and video card operate at maximum power and heat up excessively;
• the computer should not be exposed to direct sunlight, since in this case the case will heat up too much;
• As a preventative measure, it is better not to place the laptop on soft surfaces when it is actively working;
• if the laptop has been actively used for more than a year, you should disassemble the device, replace the thermoplastic and clean the fan along with the cooling system using a compressed air cylinder;
• additionally purchase external cooling, such as special stands.

What is the normal temperature for a laptop?

Now we should move on to the issue related to permissible temperature laptop. Approximate optimal indicators will be given, which vary depending on the laptop model and area of ​​​​use.

• normal CPU temperature is 30-50 degrees, maximum – 70 degrees;
• normal GPU temperature is 40-65 degrees, maximum – 85 degrees;
• Normal hard drive operation is 30-40 degrees, maximum – 45 degrees.

Thus, the most common reason for a laptop to overheat is a clogged cooling system and cooler. Due to the dust layer, the main components stop functioning normally and do not allow the device to fully cope with its tasks. To solve the problem, you will need to disassemble the laptop and clean it, and additionally apply a new layer of thermoplastic. As a result, the gadget will stop overheating and will again delight the owner with its excellent performance.

Video - Laptop is heating up, what should I do?

When deciding to buy a new computer, many users think about whether to purchase a desktop PC or give preference to a laptop. Most often the choice falls on desktop computer, since laptops are distinguished by their poor-quality cooling systems.

And even if your gaming laptop equipped with the most powerful cooling system, sooner or later you will encounter a number of problems. Why the laptop is heating up can only be determined after a thorough diagnosis of the device.

Heat

When a laptop is active, all of its components consume electricity, some of which is transformed into heat. The processor and video card do this most actively. Therefore, if powerful components are installed inside the system, the temperature will be high.

When analyzing the question of why a laptop heats up, we have to return to modern trends. The fact is that many manufacturers develop processors and video cards using a technical process that is getting smaller and smaller every year. Accordingly, the temperature of new products is much lower than in already outdated models. Therefore, the previous generation of laptops heats up more, makes noise and slows down.

Since heating directly depends on the power of the video card processor, it is obvious that budget laptops that have limited computing power, heat up less. The middle price segment is subject to higher temperatures. But still they are not the same as in gaming devices.

When buying a gaming laptop, you immediately need to be prepared for the fact that a noisy and warm “oven” will appear on the table, which will be especially warm when launching powerful games.

Reasons

Users who want to find out why their laptop is heating up often blame individual components. On the one hand, this is justified, since it is known that the video card and processor heat up the most in a device.

But not always the cause of overheating can be one of the system components. Most likely, you have noticed that after purchasing a new device, it works properly for some time. The new cooling system easily copes with high loads laptop.

But if you don’t take care and treat the operation of the laptop negligently, then sooner or later the cooling system will begin to gather dust, and, accordingly, the efficiency of its operation will decrease.

Why does the laptop get hot: what to do?

First of all, you should understand that it is important to monitor the correct operation of the device. You may be doing something that is harmful to the entire system. For example, placing the laptop on soft surfaces or covering ventilation openings.

It is very important that the ventilation holes of the laptop are always open. In this case, effective air exchange will take place inside the housing. This is why many people are critical of placing a laptop on a bed or other soft surface.

The answer to the question of why the laptop is heating up may be system overload. Not all users understand that the use of resource-intensive heavy programs entails an increase in the activity of the processor and video card, respectively, their energy consumption and heat generation. If you often use resource-intensive software, then periodically you need to give the system a rest.

It is also worth noting that it is undesirable to load the system with applications that are designed for more powerful models. In this case, you will not achieve effective work with them, and you will also critically load the laptop components.

Naturally, it is undesirable to work with a laptop in the sun in the heat. Obviously, if the CO removes hot air from the case and immediately takes it inside, there will be no effective cooling result.

New device

Many people want to figure out why the laptop gets very hot. There are two situations worth immediately noting here. Let's assume that you purchased a new laptop, which immediately started making a lot of noise and getting hot when turned on. This usually happens with game models.

It is not difficult to guess that in this case the problems are directly related to the cooling system. Most likely it is not enough for the system to operate effectively. Of course, if the heating is insignificant, the case is warm in some places, then there is nothing to worry about. The alarm will have to be sounded only when it starts to buzz or switches off in an emergency.

If you are still bothered by the fact that the laptop is heating up, you can try purchasing a special stand. It can be either ordinary, which serves only to ensure that the surface does not block the ventilation holes, or special, with built-in fans.

If your new laptop continues to get very hot and noisy, and sometimes even turns off unexpectedly, then it is best to take it back to the store for repair or replacement. More likely, this model has either an insufficiently high-quality cooling system or defects.

Problems with an old laptop

But it’s not difficult to figure out why a laptop that was purchased a couple of years ago gets very hot. Firstly, manufacturers produce models that cannot last forever. It would be unprofitable for companies if users purchased laptops every 5-10 years.

Secondly, if the system worked well before, but over time it began to heat up, slow down, or even turn off, then you need to disassemble it and clean it. This is especially important for those who have never done this.

Thirdly, during operation, viruses could have entered the system, slowing down the laptop and disrupting the operation of the processor. The latter, in turn, begin to work more actively and generate more heat.

Cleaning

If you can't figure out why your laptop heats up and turns off, answer yourself the question: “Have you cleaned it recently?” Some users forget that hairs and dust can enter the system through the vents. All this clogs not only the cooling system and cooler itself, but also other components. Therefore, it is important to clean your laptop regularly to avoid such problems.

Some users do not want to save money and take their devices to a service center. There, specialists clean out dust, change thermal paste and return the cooling system to its former efficiency. But in fact, cleaning can be done at home.

Parsing the device

A more effective cleaning is to disassemble the laptop. Of course, this is not the easiest procedure, and not everyone can handle it. But there’s nothing particularly complicated about it. In addition, it can solve the question of why it is heating up. In this case, it is important to be careful and follow the instructions.

The difficulty in this process can arise when remembering where each bolt was placed. Therefore, in the process of disassembling the laptop case, it is advisable to either photograph everything or mark it in some way. If you don’t understand how to disassemble a laptop at all, try searching the Internet for a disassembly of your particular model. It is best if you come across a video of this process. Then, together with a specialist, you can disassemble the case and get to the cooling system.

The cooling system is located on the motherboard. It consists of a cooler, a cooling circuit and a radiator. Air enters the case through a hole, which may be located at one of the ends of the laptop. Sometimes the manufacturer places it on the bottom of the device.

The motherboard also contains video adapter and central processor chips. There is also RAM and other elements.

General cleaning

To clean your laptop yourself, you need to stock up on a screwdriver, cotton swabs, a can of compressed air and antistatic gloves. Immediately put on gloves and remove the back cover of the laptop. In some models it can be fixed with bolts, in others - with special levers. Here again, it is important to understand your specific laptop model.

Sometimes, in order to get to the cooler and radiator, you need to remove not only back, but also disassemble the keyboard, remove the drive, hard drive, disable the wireless adapter.

In some laptop models, you can turn off the cooler and remove it. After this, it will be enough to wipe it with cotton swabs and blow with compressed air from a can. Everything must be done very carefully, since the laptop parts are fragile and, if handled roughly, can become deformed.

The main task is to remove large pieces of dust from the case. If you understand the system at least a little and can remove the cooler yourself, you can try lubricating it.

Replacing thermal paste

You may have to change the thermal paste as well. To do this, you need to find a processor on the motherboard. There will be marks where it was applied. You need to apply a small amount of thermal paste here. Typically, experts recommend squeezing out a portion no larger than an apple grain. The entire mass must be evenly distributed over the surface. This is easier to do with an unnecessary credit card. If everything goes well, the issue of whether it is heating up or not will not bother you for a long time.

CPU heating

Some users cannot understand why on a laptop. As mentioned earlier, when a laptop is running, the microprocessors and video card generate the most heat. These components are the most energy-consuming. The cooling system does not always cope with large amounts of warm air.

Experts identify 4 reasons why a processor may overheat:

1. Cooling system contamination.
2. Worn out thermal paste.
3. Penetration of viruses into the system.
4. Using resource-intensive programs.

We have already considered what to do in case of contamination and wear of the thermal paste; then we need to solve the remaining problems. If the system is infected with viruses, it may no longer cope with even the most simple programs. Because of this, the processor begins to work more actively and, accordingly, overheat.

If the CPU is 70%, and no programs are active on the system, the laptop is most likely infected with viruses. In this case, it is enough to install antivirus program, which removes all malware. If this does not help, as a last resort, you can reinstall Windows.

It's still much easier using resource-intensive programs. If a laptop is overloaded with software or powerful video games, it can not only overheat and make noise, but also crash or reboot.

If you need to use such resource-intensive programs, then you need to think about changing your laptop. Alternatively, you can try using a cooling pad to prevent the device from shutting down due to overheating. You can try reducing the processor power from 100% to 70%.

Hard drive heating

Why does the hard drive on a laptop get hot? Things are similar with the hard drive. Firstly, the laptop may have a low-quality cooling system that does not cope with its task. Secondly, the hard drive may be located next to components that constantly work and generate heat. Thirdly, oxidation of the contacts at the bottom of the device could occur. This also includes long-term operation, poor cable fastening and resource-intensive programs.

It is believed that the optimal hard drive temperature should not exceed 50 ˚C. If it is higher, then the magnetic coating is damaged due to physical processes.

To cope with this problem, you can purchase an additional cooling system, regularly clean the system, and monitor the correct operation of the laptop.

HP problems

At one time, many users asked the question: “Why does the HP laptop heat up?” This question most often applied to the Pavilion series models. In its top configuration, the laptop worked correctly for the first six months, but after that the temperature of all components increased. Despite futile attempts to clean the cooler, change thermal paste and buy additional new system cooling, nothing helped.

As a result, it turned out that in most cases problems were observed specifically with the operating system. The only thing that some users had to sacrifice in this case was the warranty of the laptop and the Windows license.

If the computer gets very hot, then you need to try to quickly identify the cause of this kind of phenomenon. And eliminate it if possible.

Problems of this type may require the purchase of new equipment. Accordingly, this is an extra waste of money. However, you should be extremely careful, as excessive heat can be a symptom of a serious problem.

Signs

To detect the presence of excessive heating of the hardware on a personal computer, it is not necessary to install a special additional software, receiving information from sensors.

Sometimes just indirect signs are enough. They are:

Started to work slower

Sometimes it happens that even after cleaning the PC functions quite slowly. Neither disk defragmentation nor various other manipulations help. The reason for this phenomenon may be excessively high heating of the CPU and other components computer. A significant slowdown in task execution for no apparent reason is a serious sign of a malfunction.

A beep sounds

Many desktop PC motherboards are equipped not only with dedicated sensors, but also with associated built-in speakers. If any malfunctions occur, they issue a special beep. Moreover, many such devices are programmed to signal when specified values ​​are exceeded.

Video: Computer overheats

Shuts down or reboots itself

Sometimes the PC may start to shut down or restart itself. Quite often, motherboards and BIOSes are equipped with special automated systems that perform an emergency power shutdown when any critical situations occur. For example, excessively high temperature of the components.

Coolers spin and make more noise

Cooling devices, which are powerful fans, automatically regulate the rotation speed. Moreover, usually, the larger it is, the stronger the noise produced. If for quite a long time the coolers spin very quickly without stopping, this indicates a high and not decreasing temperature of the CPU, video card, and power supply. It's worth checking.

"Artifacts" in the image

Often, when the video processor is under heavy load, various foreign inclusions appear on the monitor screen.

They might look like this:

• squares and overlaying images on top of each other;
• bright color elements that should not be on the monitor.

Sometimes this occurs due to driver problems, but most often the problem is excessive heating of the hardware. This can happen due to a variety of factors.

Causes and solutions

There can be quite a large number of reasons for excessive heating of individual PC parts. Moreover, most of them are obvious and require a minimum amount of effort to eliminate.

The most common causes of hardware overheating are:

Insufficient or faulty cooling system

Many personal computers are extremely powerful and productive machines. They consume quite a lot of energy, which naturally leads to the appearance large quantity heat. Stationary PCs of this kind must be well cooled. If heat removal is not fast enough, overheating will occur.

To deal with this problem, you can simply:

• completely replace the heat removal device;
• Install more powerful coolers on the processor and video card.

If a specific configuration has extremely high performance and conventional cooling fans (even very powerful ones) cannot cope with heat removal for some reason, you can use a specialized cooling system - liquid. It has very high efficiency.

Installing an additional fan

Almost all system units designed for stationary personal computers, are equipped with seats on which additional fans can be installed. Thus, you can very easily solve the problem with the presence of excess heat inside the PC case. Moreover, the more powerful the fan, the better.

Dustiness

The presence of a very large amount of dust inside has a negative effect on heat dissipation. system unit. The fact is that it forms a kind of web on the cooler frame, exhaust vents and other hardware elements. Dust disrupts normal heat exchange.

Solving this problem is quite simple, you need to:

If, after a good cleaning, the operating mode of the PC has not changed, you need to look for the cause of overheating in something else.

Something with the radiator mount

Hot air is removed not only using special coolers-fans, but also radiators. This component is an aluminum or copper part that is attached directly to the heat-generating surface through thermal paste. For normal operation, this part must fit as tightly as possible to the surface of the processor.

If even a small gap appears, the heat removal process worsens significantly. Which leads to an increase in heating, and, as a result, to overheating. Most often, the radiator is secured with four screws. To solve the problem, you just need to tighten them well.

High output voltage in the power supply

If problems of this type appear on the PC, it is necessary to check the output voltage at the contacts of the power supply using a special device. Sometimes, for various reasons, it can differ greatly from the nominal value.

Repairing the power supply yourself is not so easy; it requires special skills, as well as a soldering iron (hair dryer, infrared). It is much easier and sometimes even cheaper to purchase a new power supply and install it on your PC.

Video: What to do if your computer gets hot

Setting up the BIOS and system power plan

It often happens that when the processor is powerful, but is standing in a very hot room, it can overheat. This problem can be resolved not only by installing additional or more efficient cooling, but also by simply reconfiguring the power plan.

In the operating systemWindows7 this is done as follows:

It is worth setting the cooling mode to “active”. Before slowing down the processor, Windows will independently increase the rotation speed of the cooler, thereby removing heated air.

Similar actions can be carried out by going into the system BIOS. Most have the ability to set the rotation speed of the cooler, as well as the voltage supplied to the central processor. It is worth choosing such parameters that the temperature conditions return to normal, but the system performance does not decrease significantly.

Danger of overheating

Overheating of any PC components today is not as dangerous as it used to be. It happens that even after a complete failure of the cooling system, the OS continues to operate more or less stably.

But it is necessary to remember that the normal operating mode of the processor is no more than 60-70 0C, the video card is 70-80 0C. Accordingly, it is worth considering the intensity of resource use.

With a significant increase in temperature, the integrity of the computing core may be compromised. Which leads to failure of the electronic component. Typically, repairs as a result of such situations become impossible, so it is necessary to avoid their occurrence.

How to check if your computer is overheating

Any user who actively uses their PC must monitor its condition. And above all – the temperature.

This can be done in various ways:

• using special software;
• using BIOS.

The easiest and safest way to find out the heating value of your running PC is to use various programs from a third party manufacturer.

The most popular and functional are the following:

Moreover, some utilities (for example, SpeedFan) allow you not only to obtain information from special multi-sensors that monitor the operation of the PC, but also to control the fan speed in real time. What is very convenient is that you can independently regulate the cooling system and, as a result, the operating temperature.

Another sure way to check for overheating is to view the relevant information in the BIOS.

You can do this as follows:

It should be remembered that the operating mode for each processor and motherboard is purely individual. That is why you should first read the technical documentation on the Internet, which will indicate the normal operating temperature.

It is best to simply prevent any PC components from overheating.

To do this, it is necessary to perform preventive work:

It is best to simply prevent any emergency situations from occurring. This is much easier than eliminating their consequences.

The computer is heating up - what to do? It is necessary to find the cause of this phenomenon as quickly as possible and eliminate it. Since exposure to extremely high temperatures can simply lead to overheating, which can kill the hardware.

If such a phenomenon does occur, you will need to purchase new parts for your PC.

That is why, in order to avoid unnecessary expenses, it is worth diagnosing your PC as often as possible and promptly eliminating various problems that could cause damage to it at the hardware level.

Miniaturization is an inevitable process in the evolution of comfort. A compact device is always easier to transport. If you need to have constant access to the functionality of the device, its size is of great importance. Despite the advanced capabilities of laptops, the device also has a number of disadvantages. The main problem is voiced in the question: “Why does the laptop get hot?” If you are interested in information about the probable causes that increase the temperature of the device, and you want to know how to eliminate such “iron inflammation”, then the material presented in this article will be as useful as you can correctly apply it in practice.

Lack of free space and its consequences

Notice how much smaller a laptop computer is than its desktop counterpart. However, the power and performance of the “little one” can be many times greater than that of its “giant opponent”. However, the time factor always dots the i's... One way or another, a device that is used for a long time (especially when all the hardware resources of the computer are involved) will inevitably begin to heat up. The extremely close proximity of components in the interior of the case is an incredibly favorable environment for increased heat transfer. Question: “Why does the laptop get very hot?” becomes especially relevant if, among other things, the user is placed on a sofa. In this case, the soft upholstery of the headset becomes a kind of additional barrier to the much-needed air cooling system. Why is this so? The main limitation is usually the casing of the device, the ventilation holes of which sometimes cannot provide sufficient air circulation. How to avoid the negative effects of heat and what to do to ensure that your laptop computer works with “cold calculations” - read the material below.

Why does the laptop get very hot: design flaws

The iron “organism” of your electronic device is usually framed by a plastic case. In the case when the laptop model is associated with budget-class technology, there is a risk of overheating internal components increases with every slightly incorrect operational action. For example, using a laptop on your lap or working arrangement devices on a soft surface are obviously incorrect. When you work on a laptop in a dusty room or in high humidity conditions, know that negative consequences cannot be avoided. By the way, a cold environment also has a devastating effect on the laptop as a whole. It is reasonable to assume that the question: “Why does the laptop get hot?” It might not have happened if the user had been aware of all the operational nuances.

What the seller won’t say, or What the manufacturer is hiding?

First of all, you should remember that a laptop is a portable device that can function autonomously, without being tied to a power supply. However, if you use a laptop as a desktop PC, then you should not forget that “prolonged strain” on the device can be disastrous for the device if the user ignores the tactile effect - a hot case. Even if you were assured that the laptop was made taking into account all operating conditions, do not believe it - you are being misled. However, some modifications of portable computing machines are indeed adapted for use in extreme conditions. However, even happy owners of reliable devices may have a question: “Why does the laptop heat up and turn off?” Developers and manufacturers of portable computer equipment can assure the authoritative competence of their “brainchild”, but the temperature fact remains an inevitable obviousness: everything is subject to the destructive influence high temperature. Therefore, it makes sense to constantly monitor the “degrees” of the components of a long-running system.

Top “hot” problems and ways to solve them

So, why does the laptop heat up and turn off? Let's look at the main reasons for this phenomenon, and at the same time understand some of the technical nuances and design features of the laptop.

Problem #1: Dust Exposure

As already stated, computer components“constrained” by the frames of the framing structure, so to speak, by a protective shell. This part of the device can be made of different materials. Various polymers, metal frames made of steel and even titanium in use make it possible to give the laptop a different level of reliability. Many of the materials have incredibly effective heat absorption properties. However, open areas and air intakes are most susceptible to constant exposure to the external environment: dust, moisture, etc. The user often has the question: “Why does the laptop get so hot?” Most likely, there was a critical accumulation of microscopic debris inside the laptop. Dust particles are compressed around the cooling cooler and, with their quantitative mass, block the air inlet/outlet. As a result, the fan lubricant becomes clogged, and friction creates an unpleasant effect of extraneous noise.

Remedy #1: Surface cleaning

As a rule, such troubles are resolved by basic preventive actions:

• The external openings of the air channels are freed from dust layers using an ordinary construction paint brush.
• You can use a household vacuum cleaner.
• In some cases, in order to correct the situation that leads to the question “why is the HP laptop heating up,” it is necessary to remove the protective cover of the case, which covers the direct location of the cooling fan.

Attention: implementation last point deprives the user of the manufacturer's warranty. Because unauthorized access is a violation of operating rules.

Remedy No. 2: “Through the lid to the target”

If the warranty period has expired, then the user has every reason to independently restore the functionality of the cooling system. Except for contacting a specialized service center.

• Turn the laptop over and use a screwdriver to unscrew the screws of the cover, which is usually located in the upper case, on the left (rear view).
• After dismantling the protective element, use the same brush (see above) to clean the area of ​​contamination. It is worth noting that in a situation where the question is: “Why is the laptop noisy and hot?”, superficial “cleaning” is not enough - you need to lubricate the fan. In some cases, it is advisable to replace the cooling cooler.
• After completing the “sanitary” work, install the cover in its original position, first making sure that there are no unnecessary objects in the niche that you have cleared of dust.

As a result of the fact that the cooling system ceases to function fully, it often happens that during operation in the operating environment Windows computer“freezes” or simply turns off. In the first option, perhaps the system lacks RAM, in another case there is a violation of the temperature regime. An emergency shutdown is triggered, activated by the BIOS service.

Remedy #1: Dirty RAM

To clean the installed RAM strips from dust, you also need to open the corresponding protection plate. It is usually located in the middle part of the casing and is secured with two screws. Open, clean and replace the lid. In some cases, it will be necessary to “increase” the RAM potential - adding memory.

First of all - diagnosis

Often, access to the central processor is somewhat difficult and involves the immediate dismantling of housing parts and even some of the system’s external modules. Therefore, it is advisable to diagnose the equipment in order to make sure that there are grounds for the labor-intensive process. After all, sometimes visual analysis can indicate the real reason why the laptop began to heat up. It is not difficult to carry out such a check; to do this, just enter the BIOS and look at the current temperature readings of the processor in the corresponding menu. There are also standard means Windows, which can be used to ensure that the CPU is operating normally. In other cases, dismantling cannot be avoided.

Elimination method No. 2: a substance on which a lot depends...

The operation of the processor is accompanied by high heat generation. If the cooling system is not functioning properly, the thermal paste dries out. The mentioned substance serves as a kind of layer between the CPU crystal and the heatsink, which absorbs the heat emanating from the processor. As you understand, to replace the thermal paste, you need to remove the cooling part and clean the contacting surfaces from traces of the dried substance. It should be taken into account that the component involved in heat exchange is applied evenly, in a thin layer, and in no case extends beyond the boundaries of the processed planes.

Problem No. 2: “hot” video effects and resource-intensive software

Software, and in some cases multimedia, is often the reason why the question arises: “Why is my laptop heating up?” First of all, pay close attention to how the video card works. When graphics are displayed on the screen, the processor begins to “strain”, and if the user has loaded a modern toy onto his portable device, then the system uses all its resources, and then the hardware potential is given all the best. High performance requires more energy consumption, hence the increase in heat generation components of the system. Of course, you know that a powerful video card needs effective cooling, and that GPU, just like the CPU, has a blower cooler. Of course, the fan blades and disc heatsink can become clogged with dust. In this case, there is a risk of overheating of the video card parts, and the question: “why does the laptop heat up when you play” requires immediate resolution.

Remedy No. 1: software problems

A lot of software running simultaneously can also cause your computer to overheat. It would be better if you disable some applications. Firstly, you will significantly increase system performance, and secondly, you will not overload the hardware of your laptop.

Remedy #2: Discrete cleaning

As a rule, the graphics module is located in close proximity to the air channel grilles. Therefore calculate exact location a discrete video card is not difficult. By unscrewing the corresponding screws, you can remove the protective cover and clean the part from dust layers.

In conclusion

So, we looked at why the laptop heats up. However, the issue cannot be considered closed without discussing one more important moment. The fact is that another reason for the problem we are interested in may be battery laptop. To verify the reliability of suspicions, it is enough to use special utility or contact a specialized workshop for diagnostics and recommendations. Do not forget about a simple operating rule: the laptop computer should be placed on a flat table surface during operation so that nothing obstructs the access of air to the inside of the laptop. As you have probably seen, there is nothing difficult in understanding and solving the problem we are discussing. Timely preventive actions will help you prevent negative consequences This property of the unit, and let systematic temperature monitoring of the laptop become a mandatory rule for you. Productivity to you and successful service!
