The hot season of summer holidays drives us out of the noisy and stuffy city. If at work we somehow escaped from the summer heat in an air-conditioned room, then during the rest we are attracted to the sun, the sea and nature. Isn't this what we dreamed about on cold winter evenings? Finally, you can relax and betray your body to ultraviolet rays and sea water. Only I want to break this idyll a little. Pretty sure you brought your laptop or something mobile device. I'm right? Well, of course, mobile devices have become closer to us even as pets and, unlike them, accompany us everywhere: to work, leisure, travel. Just keep in mind, they, like us, do not tolerate excessive heat.

You should not rely on the built-in protection of laptops from overheating, when an automatic “switch” is activated when a set temperature is reached at the hardware level of the device. In fact, such protection is not a complete solution to problems, since the same HDD begins to feel bad already at a temperature of 40-45 degrees Celsius. This temperature rises very quickly in the summer, and if some precautions are not taken, the life of the hard drive can be easily reduced significantly.

To protect your mobile device from premature failure and, as a result, the loss of information that is very important to you,

you should follow a few simple rules:

1. Observe the safe temperature range for your laptop.

Most mobile devices function normally at 10-35 degrees Celsius. More heat can, for example, change the microgeometric parameters of the plates hard drive, which naturally leads to malfunctions during operation, and significantly shorten the life of the batteries;

2. Never leave a working laptop on the bed.

This advice is also related to the temperature regime and is relevant at any time of the year. The fact is that the air intake vents for most laptop models are located at the bottom of the case. With your carelessness, you block them, which entails a rapid increase in temperature inside the case. Use at least a regular laptop stand, but preferably a cooling one;

3. Themes no longer leave your laptop turned on in the car in the heat, including in the trunk.

We all know that even a car left in the sun for a short time turns into a gas chamber. You will sign the death warrant for your iron friend with your own hands. So if you decide to leave your laptop in the car, make sure it's turned off;

4. Avoid direct sunlight.

According to experts, ultraviolet radiation not only contributes to overheating of the laptop, but also spoils the liquid crystal display. I will not approve, but the plastic surface of the case may well change its shape. A small "hood", shading the display, and an anti-reflective protective film will protect not only the display, but also your eyes;

5. Be sure to turn off your mobile device when leaving a cool, air-conditioned room into the hot sun and back.

Let your laptop adjust to the new temperature before continuing. The fact is that condensation can form inside the laptop, which can lead to a short circuit;

6. Do not keep the laptop constantly on charge.

It would be better if you before accumulator battery device is about to sit down, fully charge it, and then unplug the adapter. With power save mode, your laptop will run longer on battery power and run cooler. Yes, if you still use your mobile device in hot weather, try not to turn on resource-intensive applications from which the processor and video card will heat up even more.

Overheating is a common problem in laptops because every year they have more and more power, and the bodies are getting thinner. In this article, we'll talk about ways to protect your laptop from overheating so that.

What is a laptop? A laptop is a computer that is ultra-compact in size, but typically performs worse than classic desktop systems. Simply put, the laptop was originally invented to perform simple, office tasks in the field: sending and receiving Email on business trips, creating text documents in a hurry, providing Internet access at various outdoor events, etc.

Laptops today are being designed for a much wider range of purposes, ranging from the simple tasks described above to the more complex ones: graphic design, video work, and even for complex games.

Tasks have expanded, power has increased, and laptop cases, on the contrary, have become thinner and often more fragile.

If a budget laptop, purchased for office tasks, is heated within acceptable limits, then the situation with cooling at powerful models is on the verge of critical already out of the box. Still would! Hot-breathing video adapters and processors were placed in such a stuffy room, but they are forced to work at full speed. Therefore, one of the most common problems with laptops is overheating.

Common causes of laptop overheating

1. The first reason for overheating This is the contamination of the cooling systems. To be more precise - dusting.
As we have already said, there is too little free space inside the laptop. Therefore, the air currents in laptops move through small airways. Often, both the CPU and the video adapter share a common heatsink. A single fan is responsible for blowing this radiator. Air is taken from below - from the bottom of the laptop, blows over the radiator and exits from the side - from the end of the device. With careless operation, when used in very dusty places, and also if the owner rarely wears a laptop for cleaning, the cooling systems become clogged with dust, air circulation is disturbed and the laptop instantly overheats.

2. Second common cause overheating- this is the loss of properties of thermal paste on CPU, video adapter and some other heating chips. The thermal paste needs to be replaced usually after 4-5 years of using the laptop. At the same time, than more powerful laptop, the faster the thermal paste can become unusable.

3. The third reason for overheating- Violation of the rules for operating a laptop. If you put the laptop on a fleecy and tight-fitting surface, such as a blanket, blanket, carpet, thick clothing, you will artificially block the air circulation, which will lead to overheating of the laptop (or first to dust ingress, clogging of radiators, and then to overheating).

• put the laptop on a clean, flat surface so that there is a gap under the bottom that allows air intake;
• do not place a working laptop on soft and fleecy surfaces, such as a sofa, armchair or carpet;
• try not to use the device in dusty environments,
• avoid using a laptop on the beach, at a construction site and other open areas with a high content of dust and dirt;
• Regularly take your laptop to a service center for cleaning and replacement of thermal paste by the hands of professionals. Contact the service center at the slightest hint of contamination of the cooling systems.

If your laptop just turns off, freezes, or just sometimes slows down in games, then this article is for you. This article describes how to identify if the laptop is overheating, as well as how to deal with overheating.

Introduction

AT this manual Let's talk about overheating. In fact, this is one of the most common problems encountered with laptops. Partially, the topic of overheating was raised in the article:. In this article I will try to reveal it more fully.

Let's first consider why the laptop overheats. There may be several reasons for this:

1. The cooling system is poorly designed. I think it's no secret to anyone that laptops are all different. Therefore, they have different systems cooling. Some have it thought out very well and with a margin, others do not have laptops. As a result, some laptops heat up weakly, while others are stronger;
2. A pile of dust and other debris in the cooling system. This happens very often. Dust clogs in front of the radiator from the fan side. In especially neglected cases, the thickness of the layer of dust, wool and other debris reaches 5-10 mm. Naturally, the efficiency of the cooling system in this case tends to zero. Here the laptop overheats;
3. Disruption of contact between the surface of the chip and the heat sink plate. This also happens. Since the time of thermal paste, which is located between the chip and the plate hardens. This can lead not only to a deterioration in its properties, but also to the fact that, due to shock or strong vibration, the heat sink plate simply moves away from the layer of hardened thermal paste and an air gap forms. This greatly complicates heat transfer and, as a result, the chip overheats;
4. Incorrect operation of the laptop. Many laptops are designed in such a way that air for cooling internal components is sucked in through holes in the bottom and / or from the side of the keyboard. If you put the laptop on a soft surface, the holes on the bottom will overlap. As a result, the laptop will simply overheat. The same applies to working with the lid closed. Some of the holes are blocked, less air enters the cooling system and the laptop overheats.

Let us now consider how overheating usually manifests itself.

Typical symptoms of laptop overheating:

1. The laptop turns off by itself;
2. The laptop freezes;
3. Games experience occasional stutters. More details about them are described in this guide:.

This happens because the overheating protection is activated. The fact is that modern processors, video cards and chipsets have thermal sensors that constantly monitor the temperature. If the temperature exceeds a certain threshold, then the processor and video card lower their frequency and supply voltage. As a result, the temperature and performance drops and the laptop starts to slow down. Also, if the laptop overheats, it may freeze or turn off. When the video card overheats, extra lines, squares, and other defects may appear on the screen. When the processor overheats, the laptop freezes and turns off with a characteristic sound jamming.

It is quite logical that in order to determine whether a laptop is overheating or not, you just need to measure the maximum temperature of the processor, video card and other components. This is what we will do now.

Temperature measurement

The utility is great for measuring laptop temperatures HWMonitor. You can download it from these links: /.

This utility shows the current, minimum and maximum temperatures since startup. We are only interested in the maximum temperature values.

Now we launch a game or other application that heavily loads the laptop. We work or play for 15 minutes and see what the utility shows HWMonitor:

Important note:the HWMonitor utility must be minimized while playing or working with the application. If you run it after you have worked or played, or at the time when you turned off the game, then you will not receive accurate data on the maximum temperature. This is due to the fact that if you remove the load, the processor and video card drop the temperature very quickly.

Now let me explain what is what:

1. THRM is the chipset. During the game, he was able to warm up to 74 degrees (right column);
2. Core #0 and Core #1 are the processor cores. They warmed up to 71 and 72 degrees;
3. GPU Core It's a video card chip. He was able to warm up to 87 degrees;
4. HDD- It's a Winchester. He warmed up to 47 degrees.

Note: if you cannot figure out what the HWMonitor utility shows you and how bad it is, then do not be shy and ask in the appropriate forum topic:. To the message necessarily add window image HWMonitor.

What temperatures are normal:

1. For the processor, the normal temperature can be considered 75-80 degrees under load. If above 90 - definitely overheating;
2. For a video card, the normal temperature is 70-90 degrees;
3. For a hard drive, temperatures up to 50-55 are normal. If it is above 60, then it is worth copying important data from the hard drive. There is a risk of losing them;
4. For the chipset, the normal temperature is up to 90 degrees.

Important note: maximum temperatures may vary from model to model. For example for nVidia graphics cards GeForce 8600M GT is normal temperature 90-95 degrees. For nVidia GeForce 9500M GS - 80-85.

If your laptop does not overheat and temperatures are significantly lower than those described above, then the cause of freezes, slowdowns and shutdowns should be looked for in the operating system and drivers. First of all, you need to try to update laptop BIOS. It is available on the website of your laptop manufacturer. If this does not help, then you should reinstall the system, try other drivers, update programs and see the recommendations from the manual:. If this does not help, then you should contact the service center, as the cause of freezes and shutdowns of the laptop may be partial breakdowns motherboard(power stabilization circuits and other things). It is very difficult to fix this at home.

If the laptop still overheats, then you need to take measures to cool it.

There are such basic ways to lower the temperature of a laptop:

1. Put something under the back end;
2. Use a cooling pad;
3. Clean the cooling system from dust;
4. Thermal paste replacement.

Let's consider each of these methods.

1. Raise the back of the laptop

In most cases, the air that cools the laptop components is sucked in through holes and slots in the bottom of the laptop. Part of the air is also sucked in from the keyboard side. Raising the back end of the laptop, we increase the gap between the bottom and the table. As a result, air circulation improves. In other words, the air that is driven through the radiator of the cooling system becomes colder. Also, by reducing the resistance of this air, more is sucked in. As a result, the maximum temperature can drop by 5-10 degrees.

Under the back end, you can put anything you like, from books to stationery rubber bands. This is how it looks like:

There is nothing complicated. Everything is simple and clear.

2. Using a cooling pad

This method is also quite simple and effective. The bottom line is that the laptop is placed on a stand with fans. These fans force air onto the bottom of the laptop. Air enters through the slots and holes in the bottom. As a result, air flow increases, which blows over the internal components of the laptop and the heatsink. In practice, the temperature drops by 5-15 degrees.

This is what the cooling pads look like:

They cost basically from 20-30 to 50-60$. You can also do this yourself. The stands are usually powered from the USB port of the laptop.

3. Cleaning the laptop cooling system from dust

Cleaning the cooling system from dust makes sense if 2-3 months have passed since the purchase. This period depends on the operating conditions of the laptop. After cleaning, the laptop will warm up in the same way as after purchase.

This is a service operation and is often not covered under warranty. If possible, entrust this operation to a service center. For a small fee, they will clean everything for you.

If you do not want to give the laptop to a service center, then you can completely clean it yourself. To do this, you need to partially disassemble the laptop. Vacuuming often does not give a serious effect.

So. Let's start. First you need to turn off the laptop, unplug it and turn it over:

Before disassembling the laptop, it is worth pulling out the battery. This must be done!. When the battery is pulled out, it is worth analyzing how to get to the fan. On the Acer Aspire 5920, for example, to do this, you need to remove the large bottom cover. It rests on these bolts:

When all the bolts that hold the cover are unscrewed, we begin to remove it a little bit:

Important note: often, in addition to bolts, the lid is held by such latches:

They must be handled very carefully so as not to break. They usually serve to securely fix the lid.

And here is the fan with a radiator that needs to be cleaned:

Now you can clean both the blades and the radiator itself:

Since I clean regularly, there is not much dust and other debris there. In practice, there are cases when a thick layer of any debris accumulates in front of the radiator. Not surprisingly, the cooling system fails to do its job and the laptop overheats.

You need to clean with a dry cloth, napkin or brush.

When finished cleaning, we collect everything back.

4. Replacing thermal paste in a laptop

This is the most hard way laptop cooling. Replacing thermal paste requires experience and knowledge. The warranty is void in this case. If possible, entrust this operation to a service center.

The essence of this method lies in the fact that laptop manufacturers usually use thick layers of thermal paste, which does not own the most the best performance. This is necessary to ensure an acceptable percentage of marriage. If you replace that thermal paste with a more efficient one, you can lower the temperature of the processor and video card by 5-15 degrees.

Laptop repair

A detailed description of how to solve hardware problems with turning on a laptop, with image defects, as well as many other problems at home.

Troubleshooting a laptop

Are you having a problem with your laptop? You don't know what to do? Then this material is for you. The solution to the problem should start from here. Here are the solutions typical problems with a laptop.

Battery malfunction (if the laptop turns off while running on battery power)

If the laptop works fine from the mains, does not turn off, does not restart, but while running on battery power, it suddenly turns off, then most likely these are problems with the battery or charge level controller.

You can try to check the contacts on the battery, maybe something got there, but in 99% these are problems with the battery and without service center not enough.

HDD problems

If before shutting down you heard strange sounds under the keyboard, squeaks or clatter, then most likely your hard drive is slowly dying. This is especially common with old laptops that are more than 5 years old.

Laptop clogged with dust

Another shutdown of the laptop may occur due to clogging of your laptop. The internal temperature rises, which leads to the operation of the overheating protection. The laptop needs to be cleaned.

Read how to clean a laptop at home.

What can a sudden shutdown of a laptop lead to?

1. If the laptop turns off due to problems with the processor, then this can lead to its breakdown, the same applies to the video card.
2. With any emergency shutdown of the laptop, the HDD suffers, a systematic shutdown can lead to failure of the HDD and subsequent replacement.
3. If the laptop is clogged with dust, it will cause the CPU, GPU and internal temperature of the laptop to rise due to the fact that the cooling system is not working at full capacity. In turn, due to the increase in temperature, any part of the laptop can fail.
4. Shutting down your laptop suddenly may result in a black screen or blue screen of death.
5. If your laptop has turned off and no longer turns on, the article “Laptop does not turn on: causes and solutions” describes in great detail common situations and provides steps that can help you.

If none of the points helped you, describe your problem in detail and we will give you an answer to it as soon as possible.

This article is very important, especially in the coming summer))) Due to their design, many laptops are prone to overheating, which can lead to breakage and costly repairs. There are various reasons for a laptop to overheat, but in summer the main one is hot weather. So how can you protect your laptop (laptop) from the heat and avoid serious material costs associated with replacing components?

So, how to protect your laptop from overheating.

Activate energy saving features

First of all, try to use the performance-oriented mode as little as possible. When you work on the Internet or use only one running program, it is worth activating energy-saving functions in the settings operating system. This will not only prolong battery life, but also prevent overheating of the laptop's processor, as it will only use the power that is needed to run active applications.

Clean coolers and vents

Dust regularly ventilation holes and coolers, because their contamination significantly impedes the cooling of the laptop. This can be done either with a vacuum cleaner or using special aerosols filled with compressed gas, which are sold in most computer stores. It will help to improve air circulation inside the laptop and the use of stands with built-in fans. The price of a high-quality model will not exceed $30, but replacing a hard drive that has failed due to overheating, for example, will cost much more.

Work where air conditioners are installed

Just like humans, computers lose significant performance if they have to operate at elevated temperatures. Therefore, long sessions of working with a laptop in the summer should be carried out only in rooms where air conditioners are installed. For continuous operation of the computer, the ideal temperature is 21 degrees Celsius. But even if your home or office is pretty chilly, remember to turn off your laptop when not in use for a long period of time, and it's especially dangerous to leave it on unattended. There are cases when overheating of the laptop led to a fire.

These tips are quite simple and do not require serious material costs, but they can help to avoid many problems even for owners of older models that are especially prone to overheating. If, after taking all the necessary measures, the laptop continues to heat up too quickly, then you should contact the specialists, and they will be able to pinpoint the causes of this problem.
