What to do a hot computer. Why is the laptop very hot and what to do? Proper operation and preventive work

Many modern laptops are not inferior in performance to stationary computers, despite their compactness. But it is not enough to simply put a productive "iron" in the laptop body, it is necessary to competently think over its cooling system, otherwise all sorts of problems may arise.

Not all manufacturers pay due attention to this, because of which users begin to notice that their laptops are very hot. This can simply lead to discomfort from using, spontaneous reboots or even to complete the combustion of the computer.

As part of this issue, consider what to do if the laptop is greatly heated.

The main reason that leads to excessive heating of the computer in the process of work is the mechanical clogging of the dust cooling system. This happens because the computer during work sucks the air, and along with the air it "flies" and dust that settles on the cooling system components.

Another reason that can lead to the fact that a portable computer is strongly heated is a cooling system malfunction. For example, such a malfunction can be non-working fan or "running out" heat removal tubes from the processor.

Note:Some "Chinese" manufacturers of laptops that insufficiently test their devices before issuing mass sales, sometimes they are not enough high-quality cooling system, which is not capable of cooling the "iron". This leads to the fact that with prolonged high loads of the heat removal tube "roast", as a result of which the entire cooling system acts inefficiently.

There are less common problems of overheating laptop, for example:

High temperature indoor, which uses a computer. If the cooling system when working picks up and sucks the hot air, it does not turn out enough to cool the components of the computer. Accordingly, it is necessary to ensure that the laptop does not stand near the heaters, fireplaces and other heat sources. At the same time, remember that in the winter the average temperature in the room is lower than in summer. It follows from this that in the cold months with a computer, there may be no problems associated with overheating, while in the summer they will manifest;
Permanent computer load with productive tasks. If the computer always works "at the limit", its cooling system may not cope. Follow the number of tasks performed on the laptop. It is not necessary to simultaneously run several demanding programs to the resources or continuously play modern games that require serious power;
Continuous movement of files.This problem is relevant for low-cost laptops in which hard drives are installed. If you are moving through them constantly files, it will lead to a gradual heating of the drive. In particular, the same problem may appear if the data is loaded from the computer, for example, through, therefore it is recommended to turn off the distribution so that such a malfunction does not occur.

As you can see from the described reasons, some of them the user can eliminate without interference in the design of the computer, changing its experience using the device. But to combat common issues, some efforts will be required.

Notebook Nowadays, there is in every second house and this article, I think as never relevant. I would like to note that the appearance of laptop computers has greatly facilitated the life and life of people who use computers every day. It is very convenient when the computer is always at hand - at home, at the cottage, in the car, in the cafe. The current laptops are able to replace powerful stationary computers, which is very pleased with both lovers play new games and users who work with demanding graphics applications.

These were all the pros, but there are no things without minuses. One of the minuses is high heating Portable PC. There is an opinion that the limiting processor temperature or video card must be no more than 75 degrees, but modern technologies Hold the temperature and higher. Before the laptop model goes on sale, it is carefully checked and is tested for all indicators (including the maximum temperature of its components) Engineers HP, Samsung, Lenovo, Sony, Asus, Compaq, etc. If you suddenly acquire a laptop, noticed when used Its strong heating, you do not need to immediately carry it back to the store and scandal. First read the reviews about him that the owners of the same model are written. If the temperatures exceed the norm run to the store (marriage maybe). (Before starting the game, run the program to see the temperature will need to turn the game or switch to the program by pressing the Alt + Tab button)

Why is the laptop heats, overheats?

I will try to answer this question available for everyone. Well, first, simply compare the size and number of coolers of a stationary PC and a laptop. All these high-performance processors of a miracle engineers "stumbled" in notebook (Translation from English. Notebook). Cooling occurs by emissions of hot air from the laptop housing and the cooling air drawing from the outside. Places for air circulation in a computer, thick with a book, and even less, very little, from here and high heating. Over time, the laptop begins to hang (most often with cyclic sound playing), it turns off according to the reasons incomprehensible to us. Here the main enemy is dust (subject to the absence of viruses, the computer operating system is in good condition). Dust particles are clogged by the channels for which air circulates. First, the processor is overheated, then the video card and all this heat is transmitted by the body to the hard disk, which does not like heat (quickly comes in disrepair). Recommended to buy to powerful notebooks Cooling coasters.

Signs of overheating laptop

1. Laptop does not turn on - Most often burns the south bridge on the motherboard, which is responsible for launching and working USB ports.
2. Ripples, "Artifacts" appears on the laptop screen - Chaotic figures, stripes. This suggests that overheating the video card (it is possible to even detach the contacts of the video card from the motherboard). Repair of such a laptop is possible (not always), but subsequently it will not be used for games and demanding programs. The principle as on the car - overheated and will overheat.
3. The laptop is heated and turns off after the short time - most often this overheating of the processor (it will help to clean it from dust, the replacement of the thermal paste at least once a year)
4. The laptop is heated and freezes in the process of work. Or games on it with cyclic sound playback. This is also overheating processor. IN modern laptop It is worth protection in the BIOS-when reached the maximum set temperature of the processor, it triggers (not everywhere). The need for prophylaxis, cleaning the laptop is obvious.

How to clean the cooler or a laptop itself from dust?

This can make each if desired. If he is no longer warranty. It is enough easy to get to the cooler, remove it and clean all the channels. There are problem laptops in which to get to the cooler to disassemble it into small parts. But and this you can make a typing in any search engine "how to disassemble your laptop model." Fortunately, there are even video instructions on the Internet for this material. Ask your questions in the comments, with an indication of the model, we will help, we will find, we will tell us, show. Later to post for example intrusion by cleaning lenovo laptop Y460.

If the programs began to slow down and hang, the cooler is noise, and the laptop itself is constantly turned off, then most likely it overheated. The most common cause of this problem is the presence of dust, which covers the cooling and ventilation system, which is why it cannot function normally. Cold air ceases to flow in the optimal amount, which provokes overheating of key parts. You can get rid of this problem by cleaning.

Among the main components of the laptop, which are constantly overheated, can be isolated by a video card, CPU and chipset. Maximum heating becomes noticeable when serious and massive data is processed. Typically, this happens in the process of functioning. graphic applications, launching new games, high-resolution video installation. Literally in a couple of minutes, the temperature of the gadget can grow on dozens of degrees. After heating, heat itself must move to the radiator and cooler system, from where it is "emitted" outside the device.

When a new device is bought and dust missing in the radiator, the device will not be very hot, because the system perfectly copes with the heat sink from the key components. However, after a certain period on coolers radiators and other elements, dust begins to accumulate, because of which the difficulties of thermal emissions beyond the limits of the laptop. Often the heating of the gadget becomes critical and an urgent power failure occurs. It happens at an excessive temperature, since a big chance of the final breakdown of the laptop appears.

Important! To prevent such a one, it is recommended to clean the devices or at least acquire a passive or active coolant coax that contribute to a decrease in temperature by several degrees.

Why is the laptop begins to warm up? Main reasons and problems

To solve the problem described above, it is necessary to identify its root causes. We are talking about:

flares of manufacturers engaged in the design of the cooling system. It usually concerns cheap models, employees of new brands do not conduct test work to reduce the cost of the device;
contamination of such components as a cooler, radiator. Often, dust penetrates into the radiator grille and covers the main components, which is why the cooled air can no longer pass. Sometimes, after the layer formed the fan ceases to rotate quickly;
disorders of the insulating layer. As a result of long-term work, Lapplet dries in thermoplastic, the thermal conductivity is worse, which provokes overheating;
failure to comply with the main requirements of operation. In some situations, users themselves are to blame for the overheating of the gadget. The design of the laptop housing involves the presence of technological holes in which cold air flows. The user may not notice them and constantly overlap.

What signs say the laptop overheats

It is understood that the laptop begins to warm very much, the following signs will help:

actively working fan during games or media viewing. The laptop can spontaneously turn off, especially when resource-intensive programs are launched - the same games and video player. After cooling, the laptop is turned on again;
compared frequent. Of course, this is not always connected directly with overheating. Freezes can occur due to software errors, driver failures and problems;
games periodically slow down. The user does not feel "smoothness" during the game in the novelties, after 30 minutes-hour, the laptop spontaneously turns off. The thing is that the processor and graphic map. Do not cope with too high temperatures and cannot fully process the picture.

What to do if the laptop is greatly heated and noise

If the user has encountered the problem of overheating of the laptop, it should be taken a number of actions that will avoid this difficulty.

Removing unnecessary programs from autoload

So, first should get rid of extra and unnecessary programslocated in autoload (running in automatic mode After the laptop turns on) to reduce the system load.

You can manage automatically downloaded programs using the msconfig utility - it allows you to see which utilities are started with the operating system, remove them and so on. Moreover, msconfig is used not only for this purpose, so it should be extremely attentive when using it. To run msconfig follows:

Buying a cooling stand

Additionally, it is recommended to purchase a cooling stand. Inside, it includes several fans serving to cool the housing. It is better to buy a model at once with several fans, since the main components of the processor type and video card are located on the edge of the device, next to the ventilation holes - if the fan is one, then it will be located in the center of the stand, if they are at least two of them, then one of them will be Just as close as possible to the place where heat is highlighted. The cooling stand will give a significant effect, but still it is worth remembering that in some period it will take to clean the laptop from dust even if the stand is used. Many raise a laptop and put it on books so that the ventilation openings are open. It also helps, but not much strongly.

Removing the processes loading CPU

Additionally, the processor power should be reduced by several tens of percent. It will also affect the heating of the graphic component, since their work is interconnected with each other.

Clean the cooling system of a laptop from clogging

Laptop cooling system cleaning from - the most an effective way Credit the problem of heating the device. This will require a number of actions, namely:

Disable the power of the laptop and remove the battery.
Extract DVD-drive - for this, there is enough unscrewing of one (two) screw on the housing from the back.
Disassemble the laptop, disconnect the identical way the main HDD, RAM (fixed through special brackets that must be rented for beginnings).
Separate the bar at the location of the speakers above the keyboard. If difficulties arose with the removal of the plank, then you first need to unscrew the screws.
Remove the loop - for this fixing the tongue stretches up, after which the loop will take off.
Disassemble the keyboard. It is fixed with the same latchs of plastic - their number varies from 4 to 8. It is recommended that you first remove the upper angular latch - it is enough to press it with a flat screwdriver and pushing the angle. With this way, you can deduct other attachments.
It will be visible motherboard - In this case, it is also necessary to unscrew the screws to disconnect it from the housing.
On the back of the motherboard there is a cooling system and a fan - they should also be removed by unscrewing the basic fasteners.
Dust from the planks is removed when using a special bruster or compressed air. To clean the fan, you will need to get a graphite lubricant.

It is necessary to determine how well the cooler rotation is. If during the functioning of the laptop he worked noisily, then this component should be disassembled, cleaned, lubricated.

Important! Before collecting Lappleop, it is strongly recommended for layer chips. It is better not to use the CCT-8 model in demand today, which is not the most effective properties. Its thermal conductivity is not effective, there is a tendency to dry after a certain period.

How to prevent overheating system?

To no longer face the system overheating, it suffices to follow certain recommendations:

it is better not to run on a regular basis those applications that require many resources are graphic utilities and modern games. Because of them, the CPU and the video card operate to the maximum power and overly heat;
the computer should not be under the right sunlight, because in this case the housing is too much heated;
as prophylactic measures, it is better not to lay a laptop on soft surfaces when it works actively;
if a laptop is actively used for more than a year, you should take a declaration of the device, the replacement of thermoplastics and cleaning the fan together with the cooling system by means of a compressed air cylinder;
additionally purchase external cooling, such as special stands.

What temperature for laptop is normal?

Now go to the question associated with the allowable laptop temperature. Approximate optimal indicators will be presented, which vary depending on the model of the laptop and the area of \u200b\u200buse.

the normal CPU temperature is 30-50 degrees, a maximum of 70 degrees;
the normal GPU temperature is 40-65 degrees, a maximum of 85 degrees;
the normal operation of the hard drive is 30-40 degrees, the maximum is 45 degrees.

Thus, the most frequent cause Overheating of the laptop is to clog the cooling system and cooler. Due to the dust layer, the main components cease to function normally and do not allow the device to fully cope with their tasks. To solve the problem, you will need to disassemble the laptop and clean it, additionally apply a new layer of thermoplastics. As a result, the gadget will cease to warm much and repairs the owner with its excellent performance.

Video - the laptop is heated, what to do?

Learned O. heating or overheating.

When a large number of Details hidden in a small "box" without sufficient air space, Heating is inevitable.

Considering that some laptops have heat conduction body From aluminum or other material, on such a laptop you can fry the scrambled eggs.

But hot laptop Does not mean that the computer has a problem, although one way or another you need to do something.

A bit of history

For the first time, the problem of overheating laptops attracted a lot of attention in about 2006, when in several news it was said about fire computers in several countries.

Then the problem was faulty batteries, and companies such as Dell, Sony and Acer recalled large batch of their laptops.

But for the most part the problem of overheating is not associated with batteries. And, nevertheless, some computers are heated so much that they can damage hDD.

Why is the laptop warm?

But if the problem is not in batteries, then what?

You may have noticed that any electronics is heated if you use it for a while. Electronic devices allocate heat During work, and the laptop is no exception.

There are two main reasons why laptops are stronger than stronger personal computers (PC):

1. Laptops are much smaller in size and all components are closely "packed" inside a small case. This means that there is not enough space in the laptop for heat dissipation.

If we consider that over time, the cooling system is clogged (dust, fine garbage), then heating occurs even faster. In this case, the laptop is better attributed to the master who captures it and applies special thermal.

Replacing the thermal staste

* Thermalcaste is a substance, transmitting heat from the processor to the radiator. Over time, she loses its properties and it needs to be changed. Experts are divided into views of the frequency of replacement thermal paste, but if your computer is very hot, it means that it is worth checking the thermal chaser and other components of the cooling system.

* Too much thermal paste should not be used, because By this, you are insulating the processor, instead of getting warm from it. Small drops thermal paste enough. The main thing is evenly distributed.

The processor is heated

2. Another problem lies in power. Since with each new laptop its power becomes more, first of all, because new oS require more power, more heat is created inside the case.

Of course, laptop manufacturers know about these problems, so they set various devices in the laptop case to cool the laptop as efficiently - coolers, ventilation holes, radiators.

But sometimes it is simply not enough. Strong heating can occur if, for example, the cooler does not work as it should, but most often the case is in the user, and not in the computer.

Laptop is just heated or overheated?

As all laptops have already been said, one way or another heats up, but if your computer turns off by itself, or very slows downSo you encountered a more challenging task. Perhaps you should attribute a laptop to the workshop.

Laptop turns off by itself

Today most laptops have protection system - They are simply disconnected at the moment when the temperature inside them almost reached a dangerous maximum.

Where there is no such protection, it can be installed. There are programs likeCore Temp CPU.that follow the processor temperature in the laptop and disconnect the computer if the temperature is too high.

You can set the program that follows the temperature of the processor, and also provides many other useful information. One of these programs is called Open Hardware Monitor (Hwmonitor)and it can be downloaded from the official site for free.

Other useful programs:

Speedfan.

You can also find out the temperature different devices Laptop (processor, hard disk, motherboard):

Find out in the instructions or the Internet, what temperature restrictions should be installed on your laptop model, and put 10 degrees less than this limit. Data enter the program.

You can also reduce the performance of the processor so that the laptop does not heat up:

How to cool the laptop if it overheats?

If your laptop does not overheat, he still can be pretty hot to the touch, which is also not very good. Here are some ways to cool the laptop:

Cleaning a laptop from dust

Check (and clean) cooler

When the laptop was heated, stretching his hand to the ventilation holes - if hot air blows, it means the cooler works, but if you almost do not feel the flow of warm air from the ventilation hole, then the cooler is scored with dust or simply does not work.

1. De-in the laptop (remove the outlet) and remove the battery.

2. Unscrew the bolts and remove the lid.

3. Find the cooler and get rid of dust with a toothbrush or a painting brush, or replace the new one (if the cooler stopped working).

* Stationery knife It will be needed to remove the cover of the cooler.

* Maybe you will need ethanolto clean the remnants of dust in the cooler and lubrication (you can use bicycle chain lubrication) To lubricate the cooler.

* May also be needed glue "Moment" or superchalterTo secure the cover of the cooler.

What if the laptop is overheated?

Do not work on the heat

High air temperature and straight sunny rays Also affect the overheating of the laptop. Even if your laptop is not very heated, high summer temperatures can create a problem with your computer - can spoil the battery or even hard drive.

If possible, keep your laptop in the shade.

Laptop Cooling Stand

The laptop is designed so that enjoy. On his reverse side, you can find small rubber legs, which not only allow him to stay still, but also raise it to be a place for air flow.

If you keep the laptop on your knees, the laptop housing will be very hot And even can burn you a little.
