Why does my laptop turn off involuntarily? Reasons why the laptop turns off when the charger is removed. Why does my laptop turn off?

Most users began to prefer compact laptops to conventional desktop computers. A laptop is a very complex device, and because of this, its owners often encounter a variety of problems. Often, any breakdown can be fixed; the main thing is to know how to act correctly in a given situation. This article will discuss the problem of the laptop automatically turning off immediately after turning it on, and ways to solve this problem.

Why does my laptop turn off?

Unfortunately, this phenomenon occurs very often. Many users are alarmed by this behavior of the laptop, and they immediately begin to look for reasons for the device to constantly turn off. There can be many of them, and the most common ones will be considered below.

Cause 1: Cooling failure

The first reason that will be discussed in this article is a malfunction of the cooling system. Unfortunately, this part of the device is the most vulnerable of all laptop systems. If you do not clean it periodically, the radiator grilles and fan will accumulate dust, which impedes air circulation and prevents the cooler from working.

If your laptop's fan is not working well, the laptop will start to heat up during operation. If the computer overheats too much, it turns off automatically to prevent its components from burning out. If the laptop cannot spin up the fan during startup, then it is likely that the laptop will turn off immediately after turning on.

In order to correct this situation, it is necessary to clean the fan blades from dust. If you are not sure that you can disassemble the laptop case yourself without damaging any components, then it is better to contact a specialist or service center. There you will also be replaced with thermal paste, which must be done regularly (at least once a year).

If you notice that the laptop has started to overheat, but it is working without any changes, then it is better to contact a technician to check the cleanliness of the cooler. If you do not get rid of dust on the cooler in time, some laptop components may burn out due to overheating.

Reason 2: Drive conflict

It may happen that certain devices connected to the laptop via the USB port may conflict with the laptop. Solving this problem is very simple.

Try disconnecting all connected devices. Also don't forget to check the card reader, it should be empty. Once you have completed all these steps, reboot your laptop.

Reason 3: Problems with HDD, RAM or DVD drive

When one of these components or several at once begins to malfunction, the laptop may turn itself off after being turned on.
To find out if there is a problem with the RAM, try disabling the memory sticks one by one. This way you can find out which one may have failed.

If the RAM is fine, proceed to check the hard drive. To do this, disable it, and if the problem persists, turn off the DVD. If the problem disappears when you turn off a component, it will have to be replaced.

Reason 4: Battery

Often, a laptop battery functions perfectly for the first five years. After this, the device begins to operate more and more often from the power supply, and over time it completely stops starting from the battery.

There is only one solution to this problem; you will have to replace the old battery with a new one.

Reason 5: BIOS Settings

The laptop may also turn off immediately after turning on due to software problems. These are mainly problems with the BIOS. If you've ever changed settings, you may have accidentally set the system to turn off automatically. To solve this problem you should go to settings and reset all settings to factory settings.

Reason 6: Virus software

If a virus appears in your system, then any of its components may begin to malfunction. This can cause many problems in the operation of the laptop. In order to solve this problem, you need to log into the system using safe mode and scan it to detect virus software. If viruses are found, remove them and restart the laptop in normal mode.

You can also perform a system rollback to the moment when the device worked without problems. To do this, do the following:

Reason 7: Short circuit

If your home has an unstable power supply, you need to be prepared for the possibility that some parts of your laptop may short circuit and burn out. Provided that this situation could happen to your laptop, do not hesitate and contact a specialist. He will help you diagnose all the parts and determine which of them is the problem. Then they will replace it for you, and the laptop will work as before.

After reading this article, you will be able to independently find out the reason for the laptop turning off. In many situations, the problem can be solved without the help of a specialist. To do this, it is enough to perform several manipulations described above. Don't forget, it's always better to prevent a problem than to solve it. If you clean the cooling system and treat all components of the laptop and its ports with care, then most likely you will not have to face the problem of turning off the laptop.

If you are not confident in your skills and doubt that you can repair the device yourself, it is better to contact a service center. Also, if you have a warranty on the device, it is better not to repair the laptop yourself, as the warranty will automatically be void in this case.

Hello, dear friends! This question can be answered quickly. And maybe you can even do it yourself. The laptop turns off by itself for the simple reason that it simply overheats, therefore, the protection is triggered and a command is given to turn off the entire laptop system.

Overheating a laptop is dangerous because the device may fail, which means you will spend a lot of money on repairing an old laptop, or maybe even buy a new one. What actions need to be taken when your laptop turns off by itself depends on what kind of failure occurred and why the laptop began to overheat. We need to figure out what can happen due to overheating and why the device heats up in the first place. In today's episode we will try to figure this out...

What can happen due to overheating?

So, we have learned that if the laptop turns off by itself, this is due to its overheating. Like all other electronic devices, a laptop has many mechanisms, and temperatures are set to ensure that these elements function correctly. When the temperature rises above the permitted threshold, the microcircuit simply fails, which can result in a complete breakdown (when the laptop stops starting) or a local one (some individual chips stop working).

Reasons for laptop overheating

1. Lack of air circulation.

All laptops have built-in special fans that circulate air, which means that important elements are cooled and do not have time to heat up. So that air can penetrate inside, special slots are made on the surface of the device. Sometimes dust can get into them, and air circulation is disrupted, which means that the laptop is not completely cooled. In addition, ventilation may be impaired due to improper use of the laptop, for example, you place the device on your lap, on a blanket or other soft surfaces that prevent air from entering the laptop openings.

2. Expiration date of thermal paste.

Thermal paste helps the computer move heat away from the processor and toward the heatsink. When the thermal paste dries, the processor begins to heat up. I once had to set up one such laptop, which turned off due to severe overheating, you can find out in more detail about the work that was carried out by me. I am attaching a link below to an article with screenshots.

3. Violation of the integrity of the cooling circuit.

This circuit runs inside the computer. Heat is not removed as efficiently, the temperature begins to cross the acceptable threshold, and then the elements that consume the most energy stop working.

4. Damage to electronic circuits.

For example, one of the microcircuits on the system board has stopped working, after which it begins to get very hot. Typically, in such a situation, the temperature of the computer case begins to rise exactly where this chip is located. Then you need to contact a technician who can repair your computer and replace the broken chip.

Signs that your computer is starting to overheat

— The fan runs non-stop, especially when you watch movies or play computer games.

— The laptop starts turning off by itself whenever it wants.

In most cases, this happens when programs are launched that consume a lot of the system, for example, computer games and players. The computer needs some time to cool down, and after that it will only be able to turn on.

— The computer begins to freeze frequently.

But it is worth noting that this process does not always mean that the laptop is overheating. Often, the computer begins to freeze when errors occur in the functioning of certain programs, drivers or the operating system.

— While playing games, the computer starts to slow down.

— Squares or lines may appear on the screen, and the computer may completely turn off at this time.

All of the above may be related to the computer's security system. The processor and video card have special temperature sensors that monitor the temperature of the chips. When the temperature rises above the permissible threshold, the system begins to forcibly reduce the speed of the computer until it cools down completely. In such cases, the computer begins to slow down, sometimes the protection system can cause the computer to shut down or reboot, which happens even more often.

You can look at the temperature in the most important components of the computer and prove to yourself that the computer is overheating, and not that there are some software problems, using special programs. To determine that the device’s temperature is too high, you just need to monitor the computer immediately after it starts and after a quarter of an hour of its continuous operation, during which time you can play a computer game.

What to do if the laptop still overheats?

— Carry out preventative maintenance on your laptop. If you don’t know what exactly needs to be done, then follow the link above and read the article that I talked about at the beginning of today’s issue.

— About once or twice a year you need to contact a technician who will clean your laptop from dust. If you carry out such cleaning yourself, you may cause your computer to fail. It often happens that when cleaning a laptop with a vacuum cleaner, you can knock out the video chip (the fan is installed above it), and the motherboard may also break. In any case, you will have to shell out a tidy sum for computer repair.

— Change the thermal paste.

This procedure is carried out every few years. Just like in the previous paragraph, it is better to entrust this procedure to a professional.

— Buy ​​a cooling pad.

Nowadays, there are a huge number of devices that will help your laptop not heat up. Such devices are effective and can extend the life of a computer by several years.

— Follow the established operating rules.

Above, we looked at the reasons why a laptop turns off. The laptop may also turn off on its own due to errors in the BIOS; in this case, you just need to reset the factory settings or update the BIOS to the latest update from the official website. You can read more in this issue.

— Viral activity on your laptop is also possible. In this case, you need to scan your laptop for viruses.

— Quite rarely there is a situation when it is incorrect.

— Sometimes a simple reinstallation of the system or it helps.

To summarize today’s episode “Why does my laptop turn off by itself”, it’s worth adding that you should never place your laptop on soft surfaces that could block the laptop’s access to cool air. In addition, be sure to ensure that the holes responsible for air circulation are not blocked.

Let's talk about the reasons why a laptop may suddenly turn off while working. I would like to note right away that this is an extremely unpleasant symptom. As a rule, this means that it’s time for your laptop to be in the hands of an experienced technician who specializes in repairing mobile devices.

Basic services

The cost of repair does not depend on the laptop model. We have spare parts in stock for all popular models. Check the cost of spare parts by phone.

The main reasons for a laptop to suddenly turn off:

Laptop suddenly shuts down while running on battery

• If your laptop works fine on mains power but experiences sudden shutdowns when running on battery power, you most likely have a problem with the battery or its charge level controller. The most advanced users can try using a special tester to measure the battery voltage with and without load. If the system shows a full charge, and the tester shows less voltage, then this is a direct route to a specialized service center. In which, after diagnostics, they will be able to determine what exactly the problem is - in the battery itself, which will have to be replaced, or, for example, in the controller on the motherboard responsible for charging the battery.

Laptop turns off when plugged in

Laptop overheating

If the laptop turns off while working from the network, then, as a rule, this is due to overheating of the mobile device. You can find many programs on the Internet that will help you determine how hot your device is during operation. If this temperature is higher than the established norm for a particular device, the laptop may turn off - this is triggered by a special overheating protection. If you see that your laptop is constantly overheating, we advise you to immediately take it to a specialized service center, because... this can lead to critical damage to the mobile device. Among such damage, the most terrible, undoubtedly, can be called spontaneous desoldering of elements on the motherboard and overheating of the processor cache.
Overheating of a laptop is mostly associated with a failure of the cooling system, as well as the presence of a large amount of dust and dirt in the laptop. I would also like to remind you that working with a laptop in bed, on your knees, or on other soft surfaces leads to improper heat exchange with the environment, which in turn leads to overheating.

Microcrack in the board

If the mobile device does not overheat, then a microcrack in the board may be to blame for the sudden shutdown of the laptop. In this case, the defect can be called “floating” and it appears from time to time. Unfortunately, in this case, only replacing the motherboard with a new one will help; naturally, such work can only be done in a specialized service center.

Soldering defect

Recently, defects or destruction of soldering produced with lead-free solder have become increasingly common. Manufacturers of mobile devices all over the world are switching to this type of solder. Unfortunately, today this type of solder can be called not very reliable.

Turning off the laptop due to an error in the BIOS firmware

• In some cases, turning off a laptop is associated with errors in the BIOS; as a rule, this is a factory defect. We can say that of all the listed reasons that could lead to a sudden shutdown of the laptop, this is one of the most “harmless”. All you have to do is contact a specialized service center, where they will flash your BIOS. After which the laptop will serve you well for many years to come.

A mobile computer is a capricious device. I worked and worked, and suddenly it turned off, abruptly, as if the power had gone out. Sudden shutdowns of a laptop (provided that after that it turns on and works again) is the first sign of brewing problems. If the cause is not removed, very soon your “iron friend” will need expensive repairs. Some of the problems that lead to shutdowns can be fixed at home, but in some cases it is better to immediately take the “pet” to specialists.

There are only two direct reasons why the laptop turns off on its own, but there are a lot of indirect reasons. Let's talk about how to understand them and solve the problem on your own, when possible.

Reason one: overheating

The temperature of the processor and the most important components of the motherboard (chipset, video chip) is monitored by a special system - hardware monitoring (HWM), consisting of measuring sensors and a controller. The latter’s task is to process incoming signals and, if permissible values ​​are exceeded, immediately turn off the computer in order to prevent thermal damage.

Most often, overheating occurs due to ineffective operation of the cooling system (CO) of the laptop due to dust contamination, as well as due to improper operation: placing the device on a pillow or other soft surface that blocks ventilation and interferes with heat dissipation.

Other reasons for the problem include:

• Excessive load, especially games. Only gaming and some multimedia laptop models with enhanced heat dissipation are designed specifically for games. The cooling system for office-class laptops and netbooks is designed only for medium and light loads.
• Cooling system malfunction. When a crack forms at the junction of the heat sink (the area that is in contact with the chip) and the thermopipe or the blower (fan) starts to work intermittently, you can’t count on good cooling.
• Incorrect installation of the cooling system after home cleaning. The heat sink is impaired by a too thick or, conversely, insufficient layer of thermal paste, as well as loose contact of the heat sink with the surface of the chip (due to weak or incorrect fixation of the former). In addition, laptop owners sometimes replace silicone gaskets with thermal paste when cleaning them themselves (equipment manufacturers use them instead of thermal paste when the cooled chips have different heights - to fill the gaps between the chips and heat sinks). The result is that the laptop turns off a few minutes after turning it on. Or even seconds.
• Unsuccessful design solution. There are laptops that are inherently more prone to overheating than others due to poor case design, CO, or the proximity of hot elements to each other.
• Overclocking the processor and video card. Mobile computers are not designed for overclocking, but you won’t see anything in life.

Symptoms of overheating

Ineffective cooling is indicated by the following:

• The laptop turns off only under high load - when watching videos or while playing games.
• The laptop body and the air flow from the vent are tactilely hot.
• The case is hot, but almost no air comes out of the vent (the grille is clogged with dust).
• The case is hot, but the air coming out of the vent is barely warm (the cooling system is not installed correctly or is faulty).
• Before shutting down, the fan was humming loudly (the cooling system is working at its limit).
• The fan operates jerkily (faulty).
• Monitoring programs (Aida64, HWiNFO, Sandra, etc.) record the high temperature of components (the maximum permissible heating of the processor, depending on the model, is 85-105 0 C, video card - 90-110 0 C, chipset - 80-100 0 C) . The screenshot shows the current and maximum core temperatures of the mobile Intel Core i3 under medium and high load. The values ​​correspond to the norm.

Sometimes the only manifestation of overheating is instability during operation of the laptop. This happens when there is poor cooling of nodes that are not controlled by hardware monitoring (for example, one of the bridges).

Consequences of overheating

As a result of prolonged operation under conditions of thermal stress, the solder contact between the crystal and the base of the chip or between the chip and the board is destroyed, followed by degradation of the chip itself. We are talking about microcircuits in a BGA package, which are attached to the board with an array of balls located on the bottom side of the microcircuit. In such cases, video chips, system logic (north and south bridges, hybrid bridges - hubs) and part of central processors for laptops are produced.

Most often, video cards fail due to overheating; processors, less often, fail. When a critical temperature threshold is reached, the latter reduce the frequency in order to cool down (this is how clock throttling or throttling technology works). And some video chips, especially on budget platforms, either lack such protection or it is ineffective.

How to solve the problem

The answer is obvious - by normalizing cooling. If the ventilation holes become dirty, it is necessary to disassemble and clean the device and replace the thermal paste and thermal pads (the latter are changed only when they dry out). Please note that due to low thermal conductivity, KPT-8 paste is not suitable for laptops.

If the cooling system fails, it is replaced. For minor defects (wire has come loose, etc.), repairs are possible.

For games, as well as for normal work on laptops that are structurally prone to overheating, it is advisable to buy a cooling pad.

False overheating

It happens that hardware monitoring makes a mistake - it perceives the normal temperature as prohibitively high and turns off the device. In simple cases, this can be treated by resetting the BIOS settings to default (read below about how to do this) or updating it. However, if the machine shuts down while updating the BIOS, there will be even more problems. If you are not sure that you can restore the firmware yourself, it is better not to risk it.

In difficult cases, you will have to contact a service center for repairs.

Reason two: the most important supply voltages go beyond the permissible limits

Correct operation of the laptop is only possible if the supply voltages fully comply with a certain level. A small deviation leads to instability - lags, freezes, reboots, and a significant one - either to burnout of board elements (if the nominal value is exceeded), or to a refusal to work (“dead” freeze, self-shutdown, etc.).

The level of supply voltages is also monitored by hardware monitoring. If the voltage sensors show an abnormality, it also shuts down the computer immediately to prevent electrical damage.

The causes of the problem may be:

• Faulty feeders - power supply (including cord and plug, and with them the connection socket) and/or battery.
• Defects in the motherboard (multicontroller, bridges, wiring, CMOS memory chip, PWM power controllers or something else).
• BIOS failure.
• Other devices - processor, RAM, video card, display, etc.

Symptoms of eating problems

• The laptop suddenly turned off and will not turn on again.
• The laptop turns off immediately after turning it on.
• After an abrupt shutdown, the device does not turn on on the first try, it works for a short time and turns off again.
• The device turns on and turns off after a few seconds. There are no signs of overheating.
• The laptop operates normally from the power supply and turns off immediately when it is disconnected (the battery has failed). Or it works normally on battery power, but turns off when the power supply is connected (the power supply is faulty).

Diagnostics at home

In such cases, there is little you can do on your own. Perhaps only:

• Test the machine with a known good processor and RAM (if any) by disconnecting peripherals and the display and connecting an external monitor. Perhaps the problem node is among them. This can be done by someone who has experience disassembling and assembling their laptop.

In all other cases, you will have to take the “pet” to the service center.

Monitoring voltage readings using programs like HWiNFO, Aida64, etc. is not informative. Signals from sensors on the way to the HWM controller pass through resistive dividers (they lower their level with an accuracy error), and programs take this indicator and try to “restore” the original signal from it. The result, accordingly, is approximate.

Can a laptop turn off due to viruses, drivers, Windows errors and programs?

Yes and no. Yes - because some viruses and faulty drivers load resources so intensively that they cause the computer to overheat and, as a result, shut down. There are also programs that can change the clock frequency of the processor and control the supply voltage of its core. No - because any impact of software is not a direct, but an indirect cause, leading to either overheating or voltage instability.

Some users call the laptop shutting down when the operating system unexpectedly shuts down (occurs on Windows 7, 8, 10, XP). The problem is usually caused by problems in the system itself, application errors, drivers, or the same viruses. Reinstalling or removing faulty drivers and programs, anti-virus scanning, and, as a last resort, reinstalling Windows will help.

There are also unclear situations, for example, when shutdown occurs every time Windows starts. Both software and hardware may be to blame for such problems. To figure it out, boot the laptop from another medium (flash drive, DVD). If the startup goes well, the reason lies in the system on the hard drive or in what “lives” in it. If not, it’s in hardware.

Sometimes the problem occurs only in certain cases, for example, when closing the lid (if the action is not set to turn off, but to go to sleep). To fix the problem, click on the battery icon in the system tray, go to “Power and Sleep Options”

and switch to a different power plan.

If there is no result, reset the BIOS to default (update it if possible), reinstall the ACPI driver downloaded from the website of your laptop model, or perform a system restore to a day when the problem did not exist.

Let's look at the reasons why your laptop turns off on its own without overheating. There may already be problems of both hardware and software nature and it is necessary to find the cause.

This article is suitable for all brands that produce laptops on Windows 10/8/7: ASUS, Acer, Lenovo, HP, Dell, MSI, Toshiba, Samsung and others. We are not responsible for your actions.

Attention! You can ask your question to a specialist at the end of the article.

STOP error when installing an OS component or driver

A blue screen on a laptop can be caused by installing a new driver or updating Windows components. Nvidia video cards are most often susceptible to this. In this situation, you will have to roll back the operating system to the state before this procedure. It’s good if the gadget can turn on after several attempts and it will be possible to remove updates and roll back drivers.

To view installed updates with the ability to remove them, enter “View installed” in the search bar and run the “View installed...” program. Updates can be removed sequentially, rebooting the laptop after each removal to determine the one that caused the problem.

If after several reboots the problem does not disappear, Windows 10 calls system recovery with a proposal to stop the selection at the checkpoint to which the rollback will be made. If the restoration is successful, a window with the relevant information will be displayed, and the gadget will reboot.

Rolling back Windows 10 will affect not only the problematic component, but also all aspects of the operating system. If, after starting the laptop, the blue screen no longer bothers you, then OS updates can be temporarily deactivated until the causes of the problem in the system are determined or the errors are corrected by the developers.

Critical error in laptop operation

While running Windows 10, a large number of factors can cause an error. The most common ones include: hardware problems, software conflicts or incompatibility with the OS, and the use of old equipment.

Microsoft offers the following methods to solve the problem:

• You should remove the new connected device, after the start of operation of which a blue screen began to be displayed.
• The Windows 10 update process can not only eliminate shortcomings in system security, but also correct errors or eliminate conflicts in the operation of the laptop or its elements.

Dust clogged

Dust is another source why the laptop turns itself off during operation. This problem is the most common and common - users rarely clean their laptops, so they are constantly dusty. If the gadget turns off by itself, then in 90% of cases the reason is dust.

Dust can accumulate everywhere: in the cooling system, video card and on the processor. If you use your laptop on a fleecy blanket, it will become clogged even faster. As a result, the cooling system will not cope with its task:

• The laptop will freeze, slow down, and overheat.
• The fan hums loudly.
• Air circulation is disrupted. If the situation is neglected, the dust layer can reach 5 - 10 mm).

After some time, the gadget will begin to turn off by itself. The solution here is simple - the laptop needs to be cleaned of dust. If you don’t understand this issue (cleaning a laptop is more difficult than a PC system unit), then it is recommended to entrust the cleaning to specialists.

Laptop turns off suddenly when running on battery

When the laptop turns off on its own without overheating, you should first check the condition of the battery. We connect the laptop to the network and test it for several hours. If it no longer turns off, then the problem is in the battery.

Typically, the battery lasts for 2 - 3 years, and laptops last on average 5 - 7 years. Batteries always break down faster.

Typical reasons for their malfunction include:

• Instant shutdown of the laptop while unplugging the power cord (the battery here is already completely inoperative).
• Incorrect charge level detection.
• “Absence” of a battery (the gadget cannot determine it, considering that there is no battery at all).

In this case, you need to replace the battery. Often the battery cannot be repaired.

Virus infection

The laptop can turn off by itself. Nowadays, various miners have begun to appear that are used to earn bitcoins (). This virus is quite insidious - it loads the video card and processor by 100%.

As a result, the laptop will freeze, slow down and get very hot even on the desktop. If you open the task manager, it will show high CPU load even when you are not running any resource-intensive programs.

Therefore, it makes sense to check your laptop for viruses. To do this, you can install any antivirus (Avira, Avast, Kaspersky) and scan Windows with a special utility to search for and remove malicious software.

System board failure

The motherboard is the main component on which all components are installed (processor, RAM, video card), so even microcracks can lead to unexpected consequences.

Typical breakdowns:

• Incorrect actions associated with disassembly and incorrect assembly.
• Filling with water, coffee, tea.
• Mechanical impact.

There may also be problems with the video adapter, cooling system, and USB ports. Experts can solve this problem. After conducting diagnostics, they will identify why the laptop turns off. If the problem is with the system board, it can be repaired or replaced.
