Samsung laptop shuts down by itself. Why the laptop began to turn off by itself and what to do

The laptop is a very complex device. Structurally, it is much more complicated than a desktop computer. At the same time, the laptop is a mobile device, users constantly carry it with them, which means that it is subjected to shocks and shakes. Therefore, laptop failure is far from uncommon. One of the most common problems is sudden shutdowns. The laptop just turns off by itself and the user cannot influence it in any way. In this material, we will consider the main reasons that can lead to the appearance of this unpleasant symptom.

Reason number 1. Overheating.

Modern laptops have very powerful hardware that radiates a lot of heat. Throw in a thin plastic case (which doesn't dissipate heat very well) and you'll realize that cooling a laptop is a very difficult task. Therefore, overheating of individual components is far from a rare occurrence for a laptop. If the temperature exceeds some boundary values, the laptop will turn off.

So if your laptop turns off by itself, then the first thing to check is the temperature of its components. Particular attention should be paid to and, since these components are most susceptible to overheating. To do this, you can use the free program.

In most cases, the cause of overheating is a breakdown in the cooling system or a large amount of dust in the laptop. It is impossible to fix such a malfunction on your own. Therefore, at the first suspicion of overheating, you should immediately contact the service center.

Reason #2: Battery.

If the laptop only turns off when running on battery power, the battery might be dead. In this case, the battery must be replaced with a new one or repaired. If you are sure that the problem is in the battery, then you can replace it yourself.

Reason number 3. Power supply.

Another common problem that can cause your laptop to shut down on its own is a broken power supply. If the problem is in the power supply, then the laptop will work fine on battery and turn off after connecting the power supply. Also, for breakdowns in the power supply, shutdowns are typical when the load on the laptop increases. For example, a laptop may work fine with office programs, but as soon as you start a game or a demanding program, the laptop turns off. Like the battery, the power supply can be replaced without visiting a service center.

Reason number 4. Software problems.

Problems at the software level can also lead to laptop shutdowns or reboots. The reason may be a virus infection, damage to system files, a conflict between programs or drivers. Typically, software shutdowns of a laptop occur along with the appearance (or the so-called BSoD).

If you see a blue screen of death and then your laptop shuts down or goes to reboot, then you most likely have a software problem. Check your computer for viruses, remove recently installed programs and drivers. If all else fails, try reinstalling Windows.

Reason number 5. Problems with the hard drive.

The hard drive is a rather fragile device, it does not withstand shocks and shocks. Therefore, in laptops, hard drives break down much more often than in desktop computers. If, along with the shutdowns on the laptop, freezes are observed when working with files, then there may be a problem with the hard drive.

Hard drives are not repairable, but easy to replace. In most laptops, the hard drive is accessible through a special hatch at the bottom of the case. In one of our articles, we already talked about.

Reason number 6. Other malfunctions.

There are other reasons that may cause the laptop to turn off by itself. For example, a microcrack may appear in the laptop motherboard. Such a defect can manifest itself only from time to time, so it is very difficult to diagnose it. If you cannot determine why your laptop is turning off by itself, then you should contact a service center.

The reasons for arbitrary shutdown are divided into two types: hardware and software. In the first case, an unplanned shutdown occurs due to defects in computer components. In the second, errors in the operating system or programs are to blame. Shutting down a laptop also causes viruses.

Software bugs

In case of critical errors in the code of the software being executed, its work is terminated. But when the software interacts with system data, the presence of bugs sometimes leads to the shutdown of the laptop. If this happens, note which programs crash when starting or running. Then uninstall or reinstall them.

Sometimes the error appears directly when Windows is running, regardless of the launch of third-party software. It is advisable to update Windows, and if this does not help, restore it using standard methods. If the laptop continues to turn off after recovery, reinstall Windows.

Virus infection

Random shutdown is also caused by malware. To get rid of them, check your system for viruses. Constant use of antivirus provides the best level of protection, but at the same time reduces performance. A compromise option is express checks.

One such application is Dr.Web CureIt!. Download the program from the official site. Run the executable file, check the box next to the item about your consent to send statistics. If you do not want developers to receive data about detected viruses, purchase the paid version. Click "Continue" to move to the next step.

For your information! Similar functionality has Kaspersky Virus Removal Tool.

Clicking the button will start a full scan for malicious code. This process is quite lengthy, but it brings the best result. Using the link below the button, you will be able to mark only the necessary sections to perform the check. It is possible to scan only the RAM to make sure that no viruses are currently running.

Start the test and wait for it to finish. The progress of the scan will be displayed in green. Found security threats will be placed in the table. Upon completion of the analysis, the Dr.Web CureIt! prompts you to select the actions that will be applied to the found vulnerabilities (ignore, cure, delete).

Laptop overheating

Of the hardware (related to iron) causes, the most common overheating of the computer. When the critical heating of the parts is reached, it automatically turns off so that they do not start to melt.

You can check the temperature of the components using the Speccy or HWiNFO utilities. Both programs are free and available for download over the Internet. The HWiNFO application allows you to view detailed information about the system, but does not have a Russian-language interface. There are versions for operating systems of various bitness - 32 and 64 bits. There are also portable versions that do not require installation. Download and run HWiNFO.

Important! You can specify the bit depth of the OS through the "System Type" section. Right-click on the "This PC" shortcut, select the bottom item of the context menu.

Select "Sensors" from the top menu. Here information is collected from all sensors of the computer, including voltage and load. To determine overheating, see the temperatures of the parts. It is indicated by a thermometer icon on the left. The table columns reflect the name of the sensor, current, minimum, maximum and average values.

When you select a parameter, the dynamics of its change will open. Here you can see how the temperature rises or falls in real time, to determine the dependence on the execution of applications. To scale the graph, specifying the extreme value in the upper text field will help. Heating is displayed at the bottom.

Note! The temperature thresholds of the components are indicated on the manufacturer's website or in the instructions. When the current temperature significantly exceeds the limit, the device turns off.

Cleaning the dust accumulated inside the case will help to reduce the heat. When it settles on the details, the free flow of cold air becomes impossible. The electronics overheat, the device turns off. It is recommended to replace the thermal paste - a creamy material used to better transfer cold from heatsinks to microcircuits. It is sold in computer stores.

There are videos on the Internet on disassembling and cleaning various models of portable devices. Use this step-by-step guide to clean your computer yourself. But if you are not sure that you can correctly assemble all the components after dusting, use the services of a specialist.

Battery failure

A broken battery also causes the computer to randomly shut down. Even if it is always connected to the power supply, the device works through the battery, its failure causes a shutdown. To diagnose, try disconnecting the battery and using the computer without it. Power will be supplied through the network. When operating normally without a battery, consider replacing it.

Difficulties with the power supply

Often the laptop turns off due to a broken power supply. In modern laptops, it is external, so disassembly is not required for diagnostics. Check the integrity of the cords that lead from the network to the power supply and from the PSU to the laptop. Also pay attention to the tightness of the connection of the connectors.

If the power from the unit is normal, the battery status will show "Charging". When the computer is plugged in but not charging, move the plug. If the contact leaves, the device is not charging.

Hard drive damage

During the operation of the laptop, unreadable sectors appear on the surface of the hard disk. They are called "broken sectors" or "bads". If the information used to run Windows is located on one of these sectors of the HDD, an error occurs as a result of which the laptop turns off by itself.

Not every person in the process of choosing a portable computer is able to accurately determine how reliable the model he is interested in is in operation. Someone relies on the “maybe” inherent in many. And some are frankly deceived by the "expert opinion" of the sales assistant. In the end, each of us has our own view of what exactly a mobile device should be. Nevertheless, due to our ignorance, and, as it often happens, filled and driven by the momentary desire “I want - and that’s it!”, We tend to commit rash actions. You may not agree, dear readers, but for the most part, we ourselves are the culprits of an unpleasant situation when the laptop turns off by itself.

However, as they say, there is no silver lining! So let's cheer up and try to solve the voiced problem, which, for your information, may be far-fetched. To know for sure, you only need to devote a few minutes of your precious time to reading the material below. Who knows, maybe an expert will wake up in you, and the experience gained will become the starting point into the fascinating world of electronics.

Instead of an introduction: a little about trade secrets

Rejoice, owners of budget modifications! Since the conventional wisdom that a cheap laptop is a highly unreliable piece of equipment is actually, oh, how far from the truth! And today's situation in the market of computing devices is a great proof of this. Competition is a great helper for the practical user. Well, the affected trick “the laptop turns off by itself” is also inherent in branded electronics. By the way, the last option is the most difficult in terms of maintenance.

So, about the secrets of manufacturers ... One way or another, but the manufacture of reliable laptops is a matter of the future. Unfortunately for some, and fortunately for some, this is indeed the case! Budget modifications are often equipped with the same parts as expensive ones, but in a stripped down version. The cooling system in any design "cannot live without dust." Well, “stuffed power”, constrained by an ultra-thin case, is still prone to overheating. In addition, the technology of planned aging as a commercial tool is applied to literally everything that surrounds us. Nevertheless, something can still be done.

The laptop itself turns off: what to do first

Of course, it is necessary to conduct a visual examination of the "patient". Dust is the worst enemy of any electronics. Especially when it comes to compactly organized devices.

Examine the laptop's vents. It is possible that dust deposits prevent free access of air.
Put your ear to the computer and listen to see if the cooling fan is running. You don't need to have an ear for music to understand the difference between the steady rustling of the cooler blades and the sound that strains the eardrums with a metallic hint.
Reset BIOS settings to default settings.
If the laptop turns off by itself, as an option, the hardware conflicts as a result of incorrectly made software changes. Roll back the operating system using a stable restore point.
By the way, especially ingenious viruses have the ability to influence the hardware components of the system. As you understand, without special software, the problem cannot be solved here. Download an antivirus utility and scan your OS for infection.

So now you know what to do first. However, let's touch on another aspect of the problem and look at the question "why the laptop overheats and turns off."

When you can "fry scrambled eggs" on a laptop

You can’t “strain” a laptop in a hot room for 6 hours in a row, playing a super-realistic arcade game: firstly, it’s harmful to your eyesight, and secondly, you can get burned on the hot case of the device. This example characterizes the main source of the problem being covered, and therefore we give it a symbolic number - one. Do you want to laugh? The largest number of users who applied to the burn center are gamers. Of course, this is a joke, but most often the “horrific” cause of the “laptop turns off during the game” problem is precisely the critical moment of overheating. Therefore, when taking part in virtual battles or traveling in other worlds, do not forget sometimes to feel the reality tactilely. Perhaps the case in the area of \u200b\u200bthe video card has warmed up, which means that it's time to cool down your gaming ardor, otherwise the graphics processor will fail.

"Creative crisis" of the operating system

The computer by the principle of action resembles a model of a person. Therefore, the unproductive state so familiar to many people, translated into machine language, is still the same dead end and digital inactivity. If a person is overwhelmed or constrained by feelings, then the computer in such situations acts rationally - it reboots. Therefore, if the laptop turns off during the game, you should apply the following recommendations:

In the "Power Options" section, pay attention to the mode you are using. In the "Additional plans" checkbox "High performance" should be activated.

Second - go to the "System" - "Advanced settings" section. In the last block of the service window "Startup and Recovery", using the corresponding button, uncheck the box "Perform automatic restart".

Most likely, the problem will disappear. However, do not forget that the unstable behavior of the OS can be caused by a hardware malfunction. With your permission, let's move on!

Energy "misunderstandings": the laptop immediately turns off

Let's consider the option when the mobile computer completely refuses to start. As a rule, in such situations, the user still observes some, albeit short-lived, “signs of life” on the laptop: the indication lights up, the hard drive starts, you can hear how the cooler blades begin to accelerate. However, something prevents the electronics from entering the operating mode. Well, this state of affairs requires a detailed analysis.

Stationary

First of all, you need to check if the power supply is connected correctly.
Is the computing device's power connector damaged?
It is also worth paying attention to the integrity of the PSU cable itself.

Most portable modifications are equipped with a special indicator that lights up when connected to an external power source. If there is no light activity, you should measure the output voltage from the PSU. In principle, a known working power supply will help to dot the i's.

Accumulator battery

If the laptop turns off when you turn it on, remove the autonomous power source and try to start the device from the network.
It is possible that the battery should be replaced, since the controller installed on it, due to its malfunction, can block the power consumption process.
If the laptop has not been used for a long time, then, most likely, the energy reserve in the battery has completely dried up. Put the device on charge and in just a few minutes try to turn on the laptop again.

Typical laptop hardware problems

Let's say that when you start the laptop itself turns off. What to do in such a situation, when it comes to incorrect power supply, you already know. With "hardware" is somewhat more complicated, but you can still figure it out on your own.

So, if at the moment of switching on you clearly hear clicks, then try to remove the hard drive and start the computer without it. If the BIOS started initialization, the “culprit” was found. You may need to replace the drive if the reason for the failure of the HDD is not software. In any case, it is worth replacing the hard drive and turning on the laptop again. Such simple manipulations are quite often effective.
The above "symptom" of a malfunction may be the result of an incorrect upgrade. Installing incompatible RAM is sure to cause a conflict in the system. Remove the RAM module. In the case when there are two of them, remove them one by one, between each test run.

Unfortunately, the methods described above are not applicable to the analysis of the performance of the central processor. If the laptop is able to “stay on track” for some time, then you can try the following diagnostic method. Put your hand closer to the middle of the case - do you feel how the laptop heats up?

And turns off, and reboots, and hangs? All this can only mean one thing - it is necessary to dismantle the protective cover in order to conduct a thorough inspection of the cooling elements, and most importantly, the condition of the thermal paste. By the way, in some cases, to get to the CPU, you will need to completely disassemble the laptop. It is worth noting that the last "procedure" requires skills and some experience.

Design features of the laptop

Why does my laptop screen randomly turn off? As we have already mentioned, there may be several reasons, and the most common of them is the display cable has failed. If you are the owner of a relatively old modification, then the connecting element may have broken. If you have a new laptop, then the inverter burned out. In any case, a visit to the workshop cannot be avoided. However, there is another explanation - the video adapter burned out. If the computer configuration allows, then you should switch from discrete graphics mode to integrated. You can easily find the corresponding section in the BIOS where you can switch video equipment.

Before I finish: a few words about software incompatibility

As a rule, the laptop turns off during operation due to a system conflict, which usually occurs as a result of using inappropriate software. In other words, the user installs software that is incompatible with the computer's hardware resources. As you understand, the problem is solved elementarily - by uninstalling, that is, by deleting. Sometimes you need to reinstall the OS. Often this kind of "shutdown whim" of a laptop can be fixed by reinstalling critical drivers. Again, the current version of the BIOS program can fix the problematic state of the laptop. However, everything must be done in stages and deliberately.

As a warning to all those who want to significantly increase the operating life of the laptop

If you previously thought that the laptop turns off by itself, then you probably already realized that your opinion was wrong. After all, there are reasons for everything, and knowing the nature of their occurrence, you can always foresee the moment of their appearance. As you can see, everything is simple! Nevertheless, there is always room for paradox. In our case, the difficulties lie in the elementary - in the lack of experience. Yes, it is our ignorance that can turn a brand new laptop into a pile of metal. By the way, it is common for a person to give up when he is tired or does not understand what exactly needs to be done. Relax, think or consult with knowledgeable people. In the end, read the operating data sheet of the laptop. In general, do not leave the problem that has arisen unresolved. Take action!

The laptop itself began to turn off during work or play. Learn more about what causes the device to turn off randomly.

The laptop may turn off by itself for several reasons. This is due to scheduled system shutdown settings, overheating, virus infection, OS malfunction, or mechanical damage.

Sleep setting

For example, Windows 10 puts a laptop to sleep if it's not used for a long time, especially if it's running on battery power. The settings are in the "Power Options" section. It happens that the manufacturer, in order to increase the battery life from the battery, sets the transition to sleep mode even after 10 minutes. This period can be increased or it is better to turn off the sleep mode completely.

Open the Settings tab, go to System - Power and sleep. Set Sleep to Never.

Mechanical damage

The laptop may turn off by itself or just the screen while tilting the display. The reason is a break in the video signal transmission bus, and only the service will help here.

When the laptop turns off without any notification - just a black screen, or a blue screen appears with an error message, then we can deal with overheating or a malfunction in device drivers.

The most common reasons:

contamination or malfunction of the cooling system;
the power button is mechanically damaged (it can turn off through poor contact at any time);
battery is defective;
malfunctions of RAM or hard drive (sometimes tapping is heard);
motherboard is defective.

What to do if the laptop turns off spontaneously?

Try to identify some of the reasons yourself.

If the laptop does not show signs of overheating, save your documents, personal photos, videos, and other data first. Create an image backup or simply transfer them individually to an external drive or over the network to another computer. Then run an antivirus or format your hard drive and reinstall Windows again.

If the laptop has expanded the RAM, added another memory bar, or replaced it with new ones, the cause may be incompatible RAM modules or poor contact. To check, reinstall the old original strips.

When a laptop shuts down on its own during prolonged use or under heavy load when playing games or editing videos, we can deal with overheating, especially on hot days.

How to tell if your laptop is overheating

The first sign is an increased case temperature at the installation sites of heating components.
The second symptom is when the fans start to run louder and louder, the increased noise continues for a long time until the laptop turns off by itself.
The third symptom is when the cooling fan is not heard at all

In the last two cases, check the processor temperature through a program such as Core Temp.

If the temperature exceeds 80°C, then there is a malfunction in the removal of heat from the case.

Possible reasons:

the cooling system is heavily contaminated;
the fan is faulty;
poorly fitting heatsink on the processor.

The cooling system becomes contaminated with dust over time, which greatly reduces its efficiency.

Carry your laptop around with you often, an accidental drop or impact can cause the cooler to fail, causing the processor or graphics card chipset to overheat.

What should I do if my laptop overheats?

Cleaning the cooling system

If the laptop overheats and turns off by itself during high load, then before taking it to a service center, clean the cooling system.

Cleaning is carried out with compressed air through the ventilation holes or with the cover removed.

To improve heat dissipation, especially if the processor or graphics card is under heavy load, especially during games, install additional cooling. To do this, a cooling pad is placed under the device.

Reducing the frequency of the processor

With a good supply of power, try lowering the processor frequency and thereby heating. If you are sure that the laptop turns off due to too high a processor temperature, try lowering the frequency by 10-20% in the advanced settings of the power plan in the "Maximum processor state" item.

Do I need to change the thermal paste

Sometimes users claim that when a laptop overheats often turns off, then you need to change the thermal paste, but this is not so. The cooling system in laptops is designed differently than in desktop computers, and rarely needs to be replaced.

The need for replacement can only be determined in the service. At home, such an operation is not recommended.

Modern portable computers are accustomed to delight users with stable work, but failures do occur. Some require minimal intervention in the system, while others require a lot of time and knowledge to solve. Let's analyze the main situations why the laptop turns off spontaneously.

Why does the laptop turn off by itself - possible reasons

There can be several reasons for self-shutdown, they all fall into 2 categories:

Software.
Mechanical.

The structure of the computer programs and applications is quite simple, but some changes or additional settings can affect the entire process. Such failures fall into the first category. Unlike mechanical problems, software failures are easier to resolve.

Failure of components, overheating and elementary clogging of the internal components of the laptop are mechanical.

Laptop turns off by itself

It is difficult to determine the exact reason for turning off the device, so it is recommended to check all options and perform the full range of actions.

Sleep setting

In Windows operating systems, the system automatically goes into sleep mode if the user does not use the laptop for a long time. Especially frequent phenomena occur with direct power supply from the battery. To check the sleep mode settings, go to the “Power Options” menu.

It often happens that the system developer tries by all means to increase the autonomy of work, for which he sets the maximum allowable time without work - 10 minutes. However, the expectation rate varies at the discretion of the user. It can also be turned off completely.

We tear off the “Settings” menu, go to the subsection “System” - “Power and sleep mode”. In the window that opens, you can set any time, or set the value to “Never”.

Sleep setting menu

In this case, the laptop will constantly work, but this will affect the duration of its work and contribute to the rapid deterioration of the battery (the maximum possible value drops from 100% to 98%, 96, etc.).

Mechanical damage

When determining mechanical failure, the elimination method should be used. However, before starting any action, it is recommended to save all important documents elsewhere, or make a backup point.

If a working laptop turns off by itself, or the screen goes blank while tilting or changing the standard position of the display, then the problem lies in the signal transmission bus. It is difficult to solve such a problem on your own, as it requires a lot of skills not only in the computer field, but also in the electrician in general. Only a service center will help.

If the device turns off without user intervention, without issuing alerts, then most likely the problem lies in the increased temperature of the video card or CPU. There is a possibility of incorrect operation of the drivers.

Main mechanical reasons:

A large amount of dirt and dust inside the case.
Temperature control problem.
Battery, RAM stick or storage device failure.
Power button contacts damaged.
Broken motherboard.

What to do if your laptop randomly shuts down

First of all, you should check the laptop for overheating.

Laptop overheating

You can understand the problem by the following signs:

The case is hot at the locations of the main elements.
The cooler starts to work loudly, and the noise constantly increases and lasts for a long period of time.
The operation of the fan is not audible at all, no noises and sounds come from the case even when using resource-intensive programs.

You can check the temperature indicator using special programs, for example, Core Temp.

Core Temp temperature checker

If the temperature of the device is more than 80 degrees - a failure in the operation of heat removal from the case.

The main cause of hardware failure of the system are malware or just a virus. This is not a novelty in the 21st century, however, some users ignore generally accepted computer security standards and install various programs without understanding why and where they come from.

To determine the presence of viruses, you can do a standard scan. Turn on the laptop, and start only the task manager. If there are no running programs, but the load on the CPU and video chip is 90% or more, there is a virus on the computer. You can deal with it by checking with a special program or by reinstalling the operating system.

If the laptop turns off by itself, but the temperature is normal and there are no viruses, then the reason is most likely in the drivers. The solution is simple - download a special utility for managing the entire system. The program will scan the state of the computer and give an assessment of the system. If necessary, update.
