The laptop is a complex device. To enable it, a number of actions take place that a simple user does not even know about. Breakage could occur on any of them.

• Burned out the power supply, or the cord is damaged.
• Battery out of order.
• Burned out motherboard, or rather any component located on it.
• Missing initialization.
• Flew operating system.

Black screen when turned on

The user turns on the laptop, but the screen does not light up. This happens a lot. There can be many reasons:

• Problems related to southern or northern bridge caused by mechanical interference or overheating.
• Does not work CPU or a video card.
• Torn plume.
• Burned out RAM or fell out of the connector.
• Not properly set up computer hardware.
• Battery"died".

The first three points can be repaired on one's own.

In the case when the laptop turns off after a long work and does not want to start - this is most likely overheat.

Should define whether the laptop turns on at all when you press the power button. That is, the indicators light up and the fans make noise and HDD... The outcome of this and will have to act.

Trouble-shooting

Battery replacement

Loop check

It may be that the monitor cable has come off or broken. This can be checked connecting another monitor.

Incorrect BIOS settings

There were cases when users with the same problem helped discharge BIOS settings to factory settings.

RAM is defective

Alternatively, one should check whether the strips are well inserted random access memory... They can also cause a black screen.

BIOS malfunctions

Perhaps the problem is settings BIOS. While it was written above, you should go to its settings and throw off them to the factory.

Freeze on startup

This can happen for many reasons. One of them is overheat... If it is strong, then you can even feel it. In this case, open the laptop. If there are many dust, then you need to eliminate it, especially the one that lies on the fans.

The hang may be due to malfunctions with a hard drive, when it starts to break, it all starts with freezes. Then you need to change the hard drive, but before that it is better to visit service center.

Operating system problems

When the operating system crashes or viruses get into it, problems with turning on may begin. Then either reinstallation Windows or cleaning from viruses if possible. You should try to go through safe mode if possible, then check the computer for viruses.

More recently, similar malfunctions have been caused by windows updates... Then you need to roll back, or reinstall.

What if your laptop won't turn on after a couple of years of active use? Earlier we have already considered the reasons, (stationary, regular computer), and today we will look at the main reasons why the laptop does not turn on. Firstly, do not worry, because sooner or later this can happen with any laptop for a number of reasons, and secondly, in this article you will read about how you can fix this problem with your own hands and continue working.

There are many reasons why your laptop won't turn on. Most of them can be associated with technical problems of the computer, which can be easily solved by fixing the laptop with your own hands, or with the help of a specialist, and those associated with a failure in the settings in the laptop itself. The problem, which is related to the settings, can be easily fixed by yourself, while the technical problems generally need to be fixed at the service center.
So, the main task for you is to determine the cause of the malfunction. Having correctly identified why the laptop does not turn on, you can fix it much faster, or give it to a specialist on time without harming him. We can say for sure that if your laptop does not react at all to the power button, does not make noise and does not even light up the screen - the problem is definitely related to malfunctions in the laptop itself. It may be necessary to replace or repair something by the hands of a master. But, if your laptop boots, and then strange things suddenly start to happen to it: it constantly reboots, freezes, etc., then be prepared for the fact that, most likely, you will have to go into the BIOS settings, use special programs, and change something.

1. If your laptop simply does not turn on and does not make any noise

Most of the problems in which the laptop does not show any signs of life at all are related to the power problem. First, you need to check if there is voltage in the outlet where you insert the laptop power plug. This can be done either with a special device or by looking at a laptop adapter. If it is connected, then a green light will be on it.

It often happens that the wires, i.e. the laptop power supply is so worn out that when plugged into an outlet, the laptop does not receive power from it at all. If it seemed to you that the laptop does not turn on for this very reason, try to check where the contact does not work, then try connecting any other suitable adapter to the laptop, or buy a new one.

Very valuable advice - if you want to avoid problems with connectors, wires, then first connect the cord to the laptop, and then just insert the plug into the outlet. This will help you avoid sparks and mini-circuits, which can be very damaging to your contacts and shorten the life of your laptop.

There may also be situations in which the light on the adapter is on, and the laptop still does not show signs of life. In this case, it is recommended that you remove the battery from the charger, then reinsert it and plug the laptop into a power outlet. Also try to disconnect from your laptop various devices, for example, an adapter for the Internet, etc., since the problem of not turning on your laptop may be in these devices.

When you have disconnected all the devices, press the power key of the laptop, and then connect each device in turn. If, for example, connecting the adapter for the Internet, your computer suddenly turns off - the problem lies in the adapter itself.

If your laptop is still under warranty, you should not do the repair yourself, but it is recommended that you immediately contact a special service center. There they will either fix it, or replace it with a new one, or return the money.

So, above were listed the most common ways why the laptop does not turn on, as well as how you can eliminate the cause of the breakdown yourself. With these methods, you did not need to disassemble the laptop, as well as enter any programs or settings. But, if you have not managed to revive your laptop, then this is not the problem and it requires a more professional approach to solving it. The most difficult problems are those associated with motherboard, contacts inside the laptop itself, as well as with the basic settings in the BIOS.

2. The laptop screen is off, but the fans inside are making noise

In this case, most likely the problems are not related to the operation of the laptop itself, but to the monitor. To do this, you need to find out which keys on your laptop are responsible for backlighting (increasing the brightness) of the screen. This usually requires clamping function key Fn, and while holding it down, press the key with the image of the sun and the up arrow (this, as a rule, is the button to increase the brightness).

You can determine that the problem lies in the screen when you try to connect your laptop to any other external monitor or the screen. If your laptop screen shows strange images of some characters or various multi-colored artifacts, and you see a normal picture on the external screen, the problem is definitely in the laptop screen. Video card problem is the most common problem, especially for those who like to play computer video games. Very often video cards overheat and fail due to poor cooling, heavy dust or dirt, etc.

There are many ventilation holes in the laptop. Those users who like to sit at the computer, holding it on their knees, on a blanket, etc. more likely to break down the computer due to dust and overheating. V computer stores you can purchase a dedicated cooling pad for your laptop. There are quite a few laptops on the market right now, and if you love playing video games, you should choose the laptop with the strongest and most powerful graphics card. Even if it seems to you that your laptop will run any game, you should not install it unless the manufacturer himself has indicated that this model of the laptop video card is suitable for games.

You always need to keep an eye on the temperature of your graphics card. This will prolong the life of your computer and save you from unexpected problems. If it seems to you that the laptop does not turn on precisely because of problems with the video card, try turning it off or just turning it off if it is discrete (it can be turned off and there is a separate built-in video card).

If this method did not help you determine the exact cause, your laptop may have serious problems with the processor, BIOS firmware, motherboard, etc.

3. What to do if your laptop turns on, but incomprehensible inscriptions appear on the screen and it freezes

If your laptop displays on the screen any information about the computer when it boots, and then it emits an incomprehensible squeak, or an error message appears on the screen, then the problem most likely may be related to the BIOS settings. To fix this problem, simply reset all settings to default. All laptops have different settings, but, in the BIOS, most likely you can find the phrase: "Load BIOS Defaults", then you will need to exit and save the settings using the button: "Save Settings and Exit".

Very often, after exiting the BIOS, the system will ask you to press any button to continue working and boot the computer. Do not be afraid to do this - press. This step can only mean that the battery that is in motherboard, will need to be replaced soon. You can have it replaced at a service center if your laptop is still under warranty.

Still, there are even more serious problems associated with why the laptop does not turn on. If before that you could solve all the problems with your own hands, then there are problems that require serious intervention. For example, problems with the hard drive or RAM.

If you are quite well versed not only in laptops, but also in computers themselves, then by listening to the noise emitted by a laptop, you can immediately determine whether your computer's hard drive is in working order or not. If the hard drive is broken, then, most likely, you will hear from the sound that it is trying to start, and it starts to emit crackling, rattling from time to time, while the image on the laptop screen may freeze.

If you think that the problem may arise due to violations in the RAM, then, provided that your laptop has access to its trims, try very carefully to clean the contacts. If cleaning the contacts did not lead to anything, then try connecting memory modules one by one, if there are several of them on your laptop, and then try turning on the computer again. On laptops with only one bar, you can try inserting it into an adjacent slot.

4. What to do if your laptop still won't turn on, or keeps restarting.

If your laptop starts to reboot even before the splash screen appears booting Windows- this indicates that you are faced with a very serious technical problem related to overheating of the south bridge. This could be because a short circuit has occurred. This problem is most likely related to a breakdown in the USB channel.

Also, the computer may endlessly restart or shutdown if the processor is clogged with dust, or the heatsink does not fit tightly to the processor and does not cool it well. This problem may be associated with low fan speeds.

If the problem lies in the power supply of the laptop, it is easy to determine by the fact that a few minutes after turning it on, the laptop turns off, and until you put it back on to charge it, it will not turn on. This problem occurs in laptops that have been in use for several years, and the battery inside it ceases to hold a charge. And this is natural, because sooner or later you will have to change the battery.

5. Error when starting from boot device

If, when you turn on your computer, various inscriptions appear on the screen on English language, which indicate that an error occurs when loading the operating system (for example, the message "Error loading operating system" appears when loading), try removing the flash drive, disk and reboot again. If this method turned out to be useless, then, most likely, there is a problem with your hard disk - either the disk is physically faulty (mechanical damage), or the disk software is faulty.

If you think that the laptop does not turn on precisely because of this, try reinstalling Windows, but if this step did not lead to anything, it means that the whole point is precisely in technical problem(physical damage to the disk).

If your laptop boots successfully, but immediately after that, you see a black or blue background on the screen, on which errors are written, this also indicates that the laptop has technical problems.

In this case, you should reinstall Windows (or, if you made backups of the operating system, restore Windows from this backup). Perhaps after that there will be no problems with the laptop. If you don't want to take the time to do this, you can first try starting Windows with bootable USB... If this method fails, take your laptop to repair or service center.

Laptop won't turn on

What to do if your laptop won't turn on

Favorite laptop stopped turning on after long (or not too) years of work? This is a fairly common problem, and we will try to tell you in detail what you can do yourself in such a situation, and when it is worth contacting a service center for professional help.

Trouble with a laptop can be either hardware or software. Software problems related to failures in software(for example, problems with BIOS settings, OS or third party applications) and can be solved right at the computer desk. Hardware problems are the physical breakdown of the laptop and its components, and mechanical repair is required to resolve them.

Power button not working - what's the problem?

If, when you try to turn it on, the laptop does not respond at all to the pressing of a button, you can confidently say that there is a hardware problem. When the power-on process fails at the moment the operating system boots, the problem can be either hardware or software. To fix problems, you must first identify the cause. To do this, we will take turns examining all the steps that need to be performed for diagnostics.

If your computer does not respond in any way to pressing the power button, first you need to exclude possible problems with meals. To get started, connect the power supply to your laptop and make sure there is voltage in the outlet you are using for charging.

First, let's define our problem a little. If the laptop does not turn on at all, i.e. does not show signs of life, then the problem is definitely hardware. If it comes to loading Windows, but then something goes wrong, freezes, reboots, then here is 50/50. Next, I will describe the diagnostic steps, and you can skip those problems that you do not have. Accurate diagnosis of a malfunction is already half of the repair.

The laptop does not turn on and shows no signs of life

In most cases, we have nutritional problems. The first thing to do is connect the laptop to the power supply and check that there is voltage in the outlet :). Power adapters usually have a light bulb to indicate they are working. And on the laptop there is a light that signals the inclusion in the network and / or the battery charge.

Then check the operation of the power supply (the indicator should be on), as well as the correctness of its operation (for this, try a working power supply similar to yours). Prove

So, dear friends. In this article, we will tell you how to cure your laptop if it does not work. What to do if you are faced with a black laptop screen, no signs of "life" in it, and so on. In general, we will try in the article to reveal all the nuances of the subject of a non-working laptop, and if you are interested, then proceed to this fascinating reading.

Laptop won't turn on

We spent a long time thinking about how best to group different variations of non-working laptops - we came up with something and we hope you figure it out.

1. So, if you press the laptop power button Nothing happens and cooling the fans are quiet, then:

Check if connected external power supply if the battery charge is very low it will not even try to turn on. Charging may be broken. If there is an indicator on the charger, make sure it is on. Make sure the power plug is connected to the laptop and the laptop has a battery. If it is possible to check Charger on another laptop - check.

Also, the reason for this behavior of the laptop can be a very serious internal malfunction, which most often can occur as a result of a fall of the laptop or a strong impact. In this case, it is necessary to take the laptop for diagnostics to a service center.

2. When you turn on the laptop the fans are noisy, but there is nothing on the screen, and a squeak is also possible.

If this is the case with you, then either something happened to the screen, or to the hardware of the laptop (internals), or it software glitch... Just in case, try to remove the battery, insert it and try again. Analyze what happened to the laptop before the problem, whether it was subjected to any drops and bumps. A black screen on a laptop can be a serious breakdown. If something began to appear on the screen, then you should go to the section below.

The laptop turns on but does not work

This section is devoted to the situation with a laptop, when it turns on, various kinds of information appear on the screen, but in fact it does not work for some reason (for example, Windows does not load on a laptop).

Windows won't boot

If Windows does not boot on your laptop, i.e. the matter does not actually reach this point, then you are in this section. Those. your computer turns on, the fan is noisy, and there is something on the screen.

Error "ntrld is missing"

Speaking in simple words a similar error occurs if something happens to boot sector or it is absent altogether. If the laptop is new, then this may be understandable by the fact that it does not have an OS, and you need to install it.

Sometimes this error occurs on working computers. This is most often the result of a BIOS out of order in the boot order. (This is especially important if there are several disks). To fix it, you need to get into the BIOS and in the Boot section put the first disk with the OS and press F10 to save and exit.

A more rare case is when a user inadvertently formats the computer and destroys important boot files... It can also be after the action of viruses. In this case, it is also worth reinstalling Windows, but it is recommended that you first save important data from the main local disk with the system.

Some symbols on the laptop screen

If there are some symbols on your screen, then try to read and search for something from the written. This concerns, of course, strange unpopular errors and messages.

Try to reset all settings in BIOS to default values, save and restart the computer.

If these symbols are on a blue background, then this laptop state is called Blue Screen and usually lasts a few seconds, after which the computer restarts. Blue screens are caused by software or hardware glitches and issues. It can often be solved looking for the error it gives.

Windows boots

If you boot Windows, but some problems occur after that, then you are here too.

Activation problems

If you have problems with activation so fatal that the computer no longer works - this is a very negative fact. You can try activating Windows by phone - there is nothing terrible about that. There are also special Windows activators on the network that can help you. You need to search for an activator for your version of Windows.

As a last resort, you can always reinstall the OS.

Laptop freezes and blue screen

If, while working in the software shell of the operating system, your laptop freezes tightly, the sound loops and nothing else happens, then this is the place for you.

For laptops, this is a very bad sign that speaks of the incompatibility of programs or OS with hardware or problems with this very hardware. Read below.

If you have frequent systematic laptop freezes, blue screens and other problems in working with your device, then it is possible that you have installed a different Windows that was included with the laptop. Very often, problems are due to incorrect Windows(Especially on laptops where Windows 8 was originally). If you have not deleted the Recovery partition, then try restarting the laptop and immediately continuously pressing F9 (on some laptops this will open a mode where you can put correct windows from the kit so to speak). Otherwise, install Windows of the version that came with the laptop and do not confuse the bitness (there are 32-bit OS, and there are 64)

We hope this article helped you solve the problem with your laptop.

Laptops have become part of the life of a modern person. Like any other technique, they sometimes break. When it stopped turning on, then you should not panic, but you should find the cause and eliminate it. In most cases, you will be able to restore your computer to work.

Causes of malfunction and their solutions

There can be a huge number of reasons why the laptop does not actually turn on. Many of them are quite simple and it will not be difficult to fix them on your own, but with some problems you will have to contact the service center.

Let's consider the main reasons due to which mobile computer may stop starting:

Comment. Very often, people say that the PC does not turn on at all, they mean that it does not boot.
Windows. This is not entirely correct reasoning, but it is popular among ordinary users.

Power problems

Power problems very often cause the PC to stop starting. Although the problem seems serious, in most cases it is easy enough to diagnose and fix it at home.

Major power problems:

• incorrect adapter connection;
• damage to cables and connectors;
• battery malfunction;
• breakdown of the power supply;
• problems in the food chain.

Often, with such problems, the power indicator of the laptop does not light up. First of all, you should check that the power supply is connected correctly and that it is plugged into an outlet. It is worth noting that even very experienced users may forget to connect the PC to the network. As a result, after the battery is discharged, the device stops starting.

Damage to power cords and connectors can be caused by a variety of reasons, including rough handling or pets that chew on the cord. You can check this malfunction using an external inspection.

Another very common problem is with the battery. In some cases, if it does not work, then the PC stops turning on even with the connected network adapter... Usually, after pressing the power button, even the cooler does not work. Therefore, it is worth trying to run the mobile computer on AC power without a battery.

The power supply fails quite often for any device. Without a charger, the laptop battery will run out sooner or later, after which the computer will stop turning on. It is very easy to check if the network adapter is working. It is enough to connect another charger from a known working computer.

Many power supplies are equipped with an indicator. Even if the light is on, it is impossible to completely eliminate problems with the network adapter. It is worth noting that there are many laptop power supplies available. Only adapters suitable for a particular model should be connected to a computer.

Problems associated with a malfunction in the power supply circuit are much less common, but they are more serious. In this case, it will not be possible to independently diagnose and even more so fix the problem. It is necessary to contact the specialists from the service center.

Defective hard drive

The hard disk stores all information and operating system computer. If it malfunctions, the computer can be turned on, but it freezes before the Windows splash screen appears. In some cases, a message about HDD error, for example, information that the disk is not the system one.

In any case, the user still has the opportunity to enter the BIOS SETUP menu. There you can check if the hard disk is detected and the correctness of the settings. If the hard drive is visible, then you can start the system from a bootable disk or flash drive and test it.

Failure of the video card and chipset microcircuits

Laptop components can also fail. This can be caused by overheating, impact damage, and so on.

Let's take a look at the details that most often cause problems with turning on the PC:

• south bridge;
• north bridge;
• video card.

In this case, the behavior of the computer can be very different. If the video card is out of order, then the image will be absent, but the fan will work and sometimes even Windows will boot, making the appropriate sound. If one of the bridges is out of order, the computer may not turn on at all or stop before loading the OS.

It is almost impossible to establish the reason in this case on your own. And an attempt at home repair is likely to only hurt. Therefore, it is better to use the services of a service center.

Video: The laptop does not turn on. Diagnostics of the board.

Other reasons

In fact, the malfunction may lie in a number of other problems.

Among which are the following:

• damage to the processor or memory;
• broken BIOS firmware;
• overheat;
• errors in Windows.

If the PC beeps when turned on, then this indicates in most cases overheating or problems with the RAM. If you have a little experience, you can try to find out on your own why this is happening. To do this, it is necessary, first of all, to remove the dust. If the problem persists, you can replace the memory modules with known good ones.

Broken BIOS firmware may result from an incorrect update. If, before the problem occurred, the user tried to carry out this operation, then he will have to contact for repair.

BIOS configuration errors are also common. It is very easy to solve this problem on your own by simply going into the SETUP menu and loading the default settings, for example, by selecting the Load Setup Defaults option.

Errors in Windows may cause the OS to fail to start. First of all, you need to find out their cause and try to solve it. Alternatively, you can try reinstalling the operating system or restoring it from the factory.

The laptop does not turn on at all

Very often, the computer will not turn on at all due to power problems. But what if the laptop does not turn on, the power button is on after pressing and nothing else happens. We'll have to look for the cause and eliminate it.

Typical actions that cause a laptop to stop turning on:

• dust cleaning;
• update;
• overheat.

If errors were made during the cleaning or updating process, then the behavior of the computer can be very different. Including the start may not occur at all. In addition, the system may not turn on due to problems with the hard disk and after overheating.

After cleaning

There are situations when, after cleaning, the laptop stops turning on. The fan may start or a squeak may be heard. On some models, the indicators also start flashing.

Cleaning a laptop involves disassembling it. The first thing to do is to disassemble it again and check the connection of all components, as well as the installation of the cooling system. It will be useful to pay attention to the thermal paste and the serviceability of the tubes that serve for the heat sink.

If the RAM modules were removed during the cleaning process, then you should try to remove them again, clean the contacts and reinstall them. You also need to check if the laptop starts up with the hard disk and optical drive disconnected.

It is worth paying attention to the sensor for opening the lid (display) when disassembling again. If not very neatly assembled, it can be out of place.

In case the execution simple tips did not lead to results and the device still does not work, then it is worth contacting the service center. It is possible that the elements were damaged by static electricity or some other problem occurred during disassembly.

After update

Problems may occur during the update. Failure to install updates correctly may cause your computer to stop turning on.

In this case, the user can set new version BIOS, drivers, or operating system patches.

The most difficult case is the inability to start the computer after BIOS updates... This happens when the user tried to interfere with the process, for example, by restarting or shutting down the computer during it, or when using unofficial firmware.

Hard drive defective

Usually in the event of a malfunction hard disk the start occurs, but the system simply hangs at the manufacturer's logo or displays information that the disk is not a system one or is damaged.

If the hard drive is detected in SETUP, then you can independently perform its diagnostics by booting from removable media and running a specialized utility like Victoria. In case of confirmation of the worst fears or the impossibility of identifying the device in the BIOS, it is necessary to check the loop.

As a last resort, you need to replace the hard drive yourself or in a service.

After overheating

Modern computers generate a lot of heat during operation. In case of severe dustiness or a malfunction of the cooling system, overheating may occur, after which some parts may fail. As a rule, it is impossible to solve the problem on your own; you will have to contact the service center for this.

The main parts that can fail as a result of overheating:

• CPU;
• video card;
• HDD;
• north and south bridges.

Spontaneous shutdowns

In some cases, the computer may turn on and even work normally for a while. Then a spontaneous shutdown occurs. There are several main reasons for this.

Let's consider the typical problems that lead to the shutdown of the device without any indication from the user:

• overheat;
• malfunction of parts;
• viruses;
• software errors;

Overheating is the most common reason for random shutdowns and reboots of mobile PCs, which can lead to device breakdown in the future. In order to avoid this, it is necessary to regularly remove dust, as well as sometimes change the heat-conducting paste.

Malfunction of parts very often also occurs due to overheating. If there were no regular cleanings, then the likelihood of this is high. You will not be able to solve this problem on your own. Therefore, it is worth contacting a specialist immediately.

Viruses can lead to incorrect work system, as a result of which the PC can turn itself off. To solve the problem, you need to download special utilities from Doctor Web or Kaspersky Lab's website, perform a full scan and remove threats.

Software errors also often lead to an arbitrary shutdown of the laptop. You need to find the reason using the code that appears on the screen at the time of the failure. After that, the problematic application should be uninstalled or try to update to the latest version.

Checking for battery problems is straightforward. You need to remove it, connect the charger and start the laptop. If the glitches are gone, then the battery needs to be replaced.

Included but

In some cases, the PC may turn on, but the download will stop at a certain point. However, error messages may appear on the screen. In some cases it does not happen Windows startup, others even fail to initialize.

Initialization fails

Initialization occurs at the time of starting the PC before proceeding to boot Windows. If the indicators light up, the cooler turns on, but there is no access to the hard disk (the corresponding light does not light up), then with a high probability the initialization failed.

Possible reasons why the laptop might not initialize:

1. malfunction of the processor, memory or video card;
2. incorrect BIOS firmware;
3. defects or damage to the south silt of the north bridge.

Regardless of the reason, you will have to carry your PC to a service center. Only a specialist with the necessary equipment in this case will be able to accurately determine the cause of the problem and eliminate it.

Windows won't start

Failure to start Windows in most cases does not indicate a hardware problem. Therefore, you can try reinstalling it, roll back to the previous state of the PC, or use the manufacturer's recovery tools.

In the hardware part, most often the inability to boot the OS is associated with hard disk problems. In this case, it will have to be replaced. Beforehand, you can try to diagnose special utilities by booting from removable media.

There are a lot of laptop malfunction options. You can diagnose and eliminate many of them yourself at home, but in case of a serious breakdown, you still have to contact the service center specialists.
