The laptop beeps and won't turn on anymore. Reset BIOS settings. Failure of the video card and chipset chips

If the laptop does not turn on, this may indicate a serious malfunction. The causes of such a breakdown can be both software and hardware failures. In the first case, you can correct the situation without disassembling the laptop and physically interfering with the system components. The second option requires a more serious approach and, in some cases, repair or replacement of one or more computer elements.

Why doesn't my laptop turn on?

Before going into detail about troubleshooting methods, it should be noted that a problem with turning on a laptop can arise for a number of reasons.

The most common factors causing malfunction:

• failure of the power adapter and, as a consequence, complete discharge batteries;
• failure of the connector or power cable;
• damage to the battery or the connector into which it is connected;
• board failure RAM or a violation of its contacts with the motherboard;
• video card failure;
• damage to the north or south bridge of the system card;
• BIOS failure.

What to do if the laptop does not turn on

Depending on the nature of the malfunction, methods for solving the problem differ. Determine which type of failure occurs in your situation and act accordingly.

The laptop does not respond at all when pressing the power button

In most cases, this behavior of the laptop is a sign of failure of one of the batteries.

The initial process for diagnosing a power system is as follows:

1. check the voltage in surge protector, connect the power adapter and pay attention to whether the indicator on it lights up (if any);
2. make sure that the power indicator on the laptop lights up;
3. disconnect the wires, remove the battery, and then reconnect the power adapter and try to start the laptop.

If nothing happens when you connect the power (no indicators light up), then the cause of the breakdown lies in the power adapter or in the charge connector on the laptop itself. Inspect the cable for damage. If possible, test the laptop's performance with a different power supply.

If performance returns after removing the battery, then that is where the problem lies. In this case, it needs to be replaced or repaired.

Perhaps this is all that can be done if the above-described signs are present on your own without the use of special tools. Keep in mind that the cause of such a malfunction can also be a failure motherboard or damage to the internal power controller.

The laptop starts and immediately turns off

This behavior in best case scenario means bad job cooling system, and at worst indicates a serious hardware failure.

In the first option, it is necessary to clean the inside of the computer and possibly change the thermal paste. But if this does not help, then most likely the south bridge of the motherboard has burned out.

Keep in mind that you can’t do this without the help of a specialist.

Startup occurs, coolers work, but the screen does not light up

First of all, check whether the laptop's screen backlight is turned on. It is usually activated by pressing the function keys.

If nothing happens, shine a flashlight on the computer screen. The image is visible - the backlight has burned out or the inverter has failed.

Other common causes of this malfunction are:

• failure of the video card;
• damage to the screen matrix or its cable;
• North bridge malfunction;
• broken BIOS firmware.

I know at least 10 people for whom the situation when the laptop does not turn on can become a real tragedy. Perhaps due to the fact that they professional activity requires sophisticated computer operation. But even for avid gamers, sudden interruptions in the operation of the device can provoke quite a panic. In general, there are hardly anyone who would deny that a poorly functioning computer is evil.

The first and most important thing to do if the laptop does not turn on is to take it to service center. Since all the reasons why a laptop does not start have quite serious roots. And you shouldn’t count on a “magic pill” - a button or program that will instantly solve your problem. Such things are checked and repaired exclusively by specialists. And you, directly, to them. There is no other option.

In this review we will highlight possible reasons why your laptop does not turn on or, when turned on, does not boot. And, if possible, we will describe how to provide him with first aid in what situations, if you are unable to go to a workshop in at the moment or soon.

Before ringing the bell, check carefully charger and battery. The second is especially true if you often work offline, without being connected to the network. Perhaps the battery is simply dead and that’s why your laptop won’t start. Try removing the battery and connecting the charger; if the computer turns on, the problem may be hidden there. If the battery does not charge when connected to power, a new one will most likely be needed. Which, in fact, will cost a pretty penny.

The reason may also be hidden in the charger. If the corresponding light does not light up when you connect it, try to carefully touch the cord, twist it, and check whether everything is connected correctly. As a last resort, try connecting a new charger to your laptop, for example, in a store. In case of positive changes, we advise you to buy it.

Laptop won't start. Reasons.

The first thing you should pay attention to is how exactly the laptop does not turn on. There are nuances here that actually determine the nature of the malfunction.

The following problems usually occur when you turn on your computer:

• - the computer turns on, but at the stage Windows boot gives an error;
• - the power turns on, the fan starts working, the corresponding lights for the hard drive and SD drive light up. But at the same time the screen is dark and after a few minutes everything goes quiet;
• - when turned on, the screen lights up and freezes, loading does not proceed;
• - the laptop turns on as usual, but freezes at the BIOS splash screen;
• - when turned on, the computer does not show any signs of life.

The first problem is often solved simply - reinstalling Windows. To prevent this from happening again, it is better to install a licensed OS, of course. Or at least high quality copy. If you entrust the process to a random technician from an advertisement, the problem may repeat itself more than once. So with this problem it is better to go to someone who understands something. Well, or to friends you trust.

In other cases, the reason that the laptop does not boot may be:

• - failure of chipset or video card chips (this is especially common with nVidia 8th series);
• - BIOS firmware corruption;
• - failure of RAM;
• - failure of the power supply circuit;
• - poor contact;
• - damage to other elements.

What to do if the laptop does not turn on

First, remove and put back the battery. It’s hard to say in how many cases this helps, but it’s such a mandatory ritual.

1. If you have a non-problematic video card installed (and this is considered, let us remind you, nVidia 8th series), you can try restoring the BIOS - the corresponding manual is not difficult to find on the Internet. If it does, then the only solution is to warm it up.
2. Disconnect the hard drive, CD/DVD drive, USB devices. You can do the same with the keyboard and touchpad cables, Wi-Fi adapter. By the way, you can clean the contacts of the video card and memory modules. After that, try turning on the laptop. If it turns on and beeps, install all disabled devices one by one. This way you will find out which of them is preventing you from finishing your game calmly.
3. If that doesn't help, try resetting the BIOS (CMOS) settings. Some devices have special jumpers for this. If they are not there, you need to remove them CMOS battery(it is small) - often, it is connected to the motherboard by wires.
4. If this does not help, you can try warming up the chips. This will return comparatively normal work laptop for some time, up to several months. But maybe just for a couple of days. So the method is also not universal.

If the actions described above scare you or there is no banal desire to interfere in places where there is little understanding, drag your computer to a service center. And the sooner you need a correct, adequate device, the faster.

Firstly, the service center will tell you exactly what is broken or malfunctioning. And in our workshop they will also do it for free. Secondly, this way you definitely won’t make your computer worse by trying to warm up the chips and resetting the BIOS settings. It is better to entrust this to those who specialize in this. Those. us.

If you press the power button and the laptop does not boot, then this can be called an unpleasant moment. Situations in in this case can be different: the laptop does not boot (black screen and the startup process does not happen at all), the laptop turns on, but does not boot, or it boots, but the screen is black, and only an experienced specialist can decide what to do in such cases. First, let's try to figure it out a little on our own. Firstly, the laptop may not turn on at all, to understand this, just listen and look to see if the power indicators light up. Secondly, the device may show “signs of life”, that is, the indicators will light up, the noise of the fan will be heard, but the screen will still remain black. There may be many reasons why a laptop behaves this way, but there is no need to panic right away, since it won’t take much time to solve them at the Serty Service computer repair center and, as a rule, the repairs or maintenance required when such a problem occurs is relatively inexpensive. Question: “The laptop won’t boot, what should I do?” - no longer a problem!

Reasons why you may be seeing a black screen on your laptop

Basically, if a laptop does not turn on or its screen does not light up, the reasons lie in its hardware and require diagnostics at a service center. However, if the laptop does not react at all to pressing the power button, you can try removing and inserting the battery, try turning on the laptop without a battery using only the power supply. You should also pay attention to whether the battery charging indicator lights up when the power supply is connected; perhaps it is the one that has failed, and the battery is completely discharged.

The most common problems that require repair under service conditions and lead to the screen not lighting up include:

• For relatively old laptops with gas discharge lamp backlight, both the lamp itself and the inverter powering it can fail;
• Failed internal power controller;
• Failure of the cables supplying power to the lamp or LED matrix;
• BIOS firmware failure;
• Problems with other laptop components that can be called more serious and expensive to repair, for example, failure of RAM or video card.

You will also not be able to start your laptop normally if it is infected with viruses or crashes. operating system, however, in this case you should still see the BIOS loading process on the screen, and the problem is most likely software in nature. You can check this, for example, by trying to boot your laptop from a flash drive or optical disk, on which it is recorded special version a system designed to test a computer and gain access to the disk when the main system does not boot.

How to solve the problem of a black screen on a laptop

If you cannot turn on your laptop at all, and have tried removing the battery, turning it on from the power supply, and also checking the integrity of the cords and contacts, there is only one solution to the problem - take the device to a service center.

If the laptop simply does not boot and a black screen appears already during system boot, you can try checking it for viruses by booting from special disk or try to reinstall the system. However, if you do not have experience in performing such restoration work, it will be easier and faster to solve the problem by contacting qualified Serty Service specialists.

Let's look at the main reasons why your laptop won't turn on and what you can do now.

It should be immediately clarified that there can be a lot of reasons for failure and they will be of both hardware and software nature. We will check everything in order and look for our case. If anything, contact a workshop in your city.

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.

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

Often such problems are related to nutrition. The first thing you need to do is connect the laptop to the power supply to check for voltage in the outlet. The adapters are equipped with a power light, which indicates its functionality. The laptop has a light that lights up when it is plugged in or the battery is charging.

Most often, the reason is a power supply that does not work or is not functioning properly (here you need to try a similar working one), due to the presence of bad contacts in the connectors, kinked or broken wires. Therefore, we look and draw conclusions at what stage the voltage disappears.

To avoid problems with the power connector, it is recommended to first insert the power plug into the laptop, and then only the power cord into the outlet. This will eliminate the possibility of a short-term spark occurring when connecting the plug, which could damage the contacts.

If the laptop does not turn on, but everything is “on”, then the problem may not only lie in the power supply. You should remove the battery and connect the device again without it, then after 10 minutes put the battery back. Also turn off all external connected devices, you can also turn off wifi adapter, if the design allows.

If everything works, then return the devices one by one. This is how the reason is determined.

Hard drive is faulty

In case of malfunction hard drive The laptop can be turned on, but before displaying Windows screensavers it freezes. In some cases, a message appears about HDD error, for example, information that the disk is not a system one.

In any case, the user still has the opportunity to enter the BIOS. There you can check whether the settings are correct and whether the hard drive is detected. If the hard drive is visible, then the system can be started from bootable flash drive or disk for testing it.

Damage to chipset and video card chips

Various laptop components can fail. The causes of failure may be damage due to impact, overheating, etc.

The most common problems that arise when turning on a laptop are:

• Video card.
• North Bridge.
• South Bridge.

When a laptop breaks down, its behavior may vary. If the video card fails, then there is no picture, but the fan will function and Windows may even boot, making appropriate sounds. If one of the bridges breaks, the device will stop before loading the OS or will not turn on at all.

In this case, it is almost impossible to determine the cause yourself. At home, attempting repairs can damage the device, so it is better to contact a service center.

Other reasons

In practice, a malfunction can occur in a number of cases:

• Error in Windows work.
• Overheat.
• Broken BIOS firmware.
• Damage to memory or processor.

If the laptop beeps when turned on, this indicates problems with the RAM or overheating. If you have a little experience, you can independently identify the problems and why this happened.

First you need to remove the dust. If the failure remains, then the memory modules should be replaced with known good ones.

The problem with broken BIOS firmware appears after an incorrect update. Errors often occur during BIOS configuration. This problem It's quite easy to decide on your own. You should go to the SETUP menu, load the default settings, for example, select the Load Setup Defaults function.

Errors may appear in Windows, resulting in the operating system not starting. It is necessary to determine their cause and solve the problem. Alternatively, you can reinstall the OS or restore the installed one.

Often the laptop does not start due to power problems. After pressing the power button, the power button lights up, but then nothing happens. The cause should be found and eliminated.

The laptop stops turning on due to the following typical actions:

• Update.
• Cleaning from dust.

To troubleshoot problems, you can replace the battery:

After cleaning

After cleaning, the laptop may not turn on. In this case, the fan may start or make a squeaking sound. The indicators may flash on some models.

The process of cleaning a laptop involves disassembling it. First, you need to re-disassemble the device and check the connection of all components and the installation of the cooling system. It is important to pay attention to the thermal paste.

If RAM modules were removed during cleaning, you must try to remove them again, clean the contacts and reinstall them. It is important to check whether the laptop starts with the optical drive and hard drive disconnected.

When disassembling again, you need to pay attention to the lid opening sensor. If the assembly is not carried out very carefully, then it may not be in the right place.

If the above tips do not help, then you should turn to professionals. There is a possibility that parts were damaged by static electricity during disassembly or some other problem occurred.

After update

When updating, problems may occur. When updates are installed incorrectly, the laptop stops turning on. The user can then set new version drivers, BIOS or OS patches.

Most difficult case is the inability to start the device after updating the BIOS. This happens when the user interferes with the process, for example by turning off or restarting the computer while updating or using unofficial firmware.

It wouldn't hurt to reset the settings to default. To do this, you need to remove the battery for a few minutes or short circuit system board corresponding jumper. In practice, this is not always possible to resolve the problem.

If the problem started after Windows updates or drivers, you should simply roll back to the previous restore point using safe mode. Restoring the operating system or returning to the state may also help, if the model supports such a function.

After overheating

Modern laptops generate a lot of heat during operation. If the cooling system is faulty or there is heavy dust, overheating occurs, which can cause some parts to break.

The following parts may fail due to overheating:

• Southern and north bridge s.
• Hard drive.
• Video card.
• CPU.

Spontaneous shutdowns

In some situations, the laptop may turn on and function normally for a while. Then it happens spontaneous shutdown. Main causes of failure:

• Faulty parts.
• Software errors.
• Overheat.

The most common reason for laptops to turn off is overheating, which can further lead to damage to the product. To avoid this, you should regularly remove dust and change the thermal conductive paste.

Quite often, parts malfunction due to overheating. If you do not carry out regular cleanings, this probability increases significantly.

Correct work systems can be damaged by viruses. As a result, the device will turn itself off. The issue can be resolved using special utility from the Kaspersky Lab website or Doctor Web, performing a full scan and removing threats.

At software errors you need to find the reason using the code that is displayed on the screen at the time of the failure. Then the problematic application needs to be removed or updated.

Cannot start from boot device

When loading Windows on English Various messages may be displayed, for example “Error loading operating system”. The first step is to remove the disk from the drive, all flash drives and reboot the device. If this does not solve the issue, then the reason is software problem hard drive or hardware.

Most accessible method restoration of functionality will be reinstalling Windows. If this helped, then the reason was at the software level.

Another possible option is when it starts Windows download, but then the laptop reboots itself, showing errors on a blue or black screen. Here, hardware or software failures may also be the cause.

The right way check this will be reinstalling the OS. An easy way to check is to start the system from a bootable USB flash drive. If the device does not start, then it should be taken in for repair.

The difficulty of repairing all-in-one computers, in particular laptops, is that the replacement of individual functional modules is not provided. That's why regular user there is little that can be done to restore the functionality of the equipment.

If you carefully study the situation, it may well turn out that the reason is quite trivial and can be solved without the involvement of specialists from the service center. Therefore, first you need to consider in detail what is happening and how exactly it does not turn on Asus laptop.

External problems

First, external obstacles to normal operation are looked for.

• If connected to the computer peripherals, printer, fax, cable connections have been made - a malfunction of the connected equipment can cause the laptop to not work.
• Disconnect all external connections. At the same time, during the disconnection process, carefully inspect all connectors.
• Damaged or torn contactors, dirt, dust, bent contacts - all this can prevent the device from turning on.

One of the most common reasons for an Asus laptop not turning on is careless handling of the computer. When moving it with the power supply connected, it is very easy to damage the rather thin, vulnerable connecting terminals or break the wires. In this case, it is necessary to replace the connectors or connecting cables.

The laptop may not turn on immediately after being left in an environment for a long time. low temperatures. According to the instructions, after bringing the PC into the room from the cold, you must wait at least two hours before trying to turn it on. In a warm room, condensation and moisture may appear on cold parts, which will lead to a short circuit and failure of the electronics.

Power problems

If the battery has not been infected for a long time, when restart The charging progress indicators will light up. But the device itself will not turn on - there is not enough charging power. In this case, you need to wait a while to replenish the electricity reserves in the laptop battery.

If no indicators light up, you need to check the presence of current in the sockets and the correct connection of the power supply. Are there any external damages in the wires? Are contact groups intact? If possible, it would be a good idea to check the power supply by replacing it with a known working one.

Asus laptop turns on and off quickly

Most often, the device turns off immediately after trying to turn it on due to a malfunction in the cooling system.

1. A lot of dust has accumulated in the case.
2. Coolers are faulty.
3. Dust completely clogged the radiator grille.
4. Thermal paste, necessary for normal cooling of electronic components, has dried out.

Less commonly, a short circuit in the north or south bridge or a faulty video card can cause the computer to turn off immediately after turning it on. Short circuits in electronics often occur due to liquid spilled on the keyboard. Although the moisture was quickly removed, a few drops may have leaked inside and this will inevitably lead to a short circuit and malfunction. If the PC was accidentally flooded with water, tea, wine, you must immediately turn off the power, remove the battery and return the device to a service center as soon as possible for drying and checking its functionality.

The lights are on, the fans are noisy, but the laptop won't start.

The device seems to have turned on, the noise of the fans rotating is heard, but the screen does not light up and the HDD indicator does not blink.

• Violations in the BIOS firmware.
• Problems with memory or processor.
• The north bridge of the motherboard is faulty.

Laptop starts loading BIOS and then shuts down

Or it reboots over and over again. In this case, the following problems are possible.

1. Overheats south bridge. Most likely due to short circuit. Usually such a malfunction is preceded by some kind of problem with the USB.
2. The processor overheats due to accumulated dust and incomplete contact of the radiator. In this case, you can hear the noise of the cooler operating at high speeds.
3. No power coming from external unit, and the internal battery is very discharged. The laptop has enough energy to start, but not enough to work.

The laptop turns off when loading OS Windows

If the computer turns on, the BIOS goes through all the stages normally, and when the operating system starts up, crashes begin and the boot is interrupted - there is a high probability of problems with Windows or something has happened viral infection. The simplest solution is to roll back to factory settings or completely reinstall OS Windows. As practice shows, after violations in the registry or damage system files because of viruses to find the real reason problems are almost impossible and it is easier to install Windows again. In mild cases, simply rolling back the system to one of the previous states helps.

Laptop does not work on battery

When plugged into the network, the laptop’s external power supply turns on, and internal source doesn't want to work. The following problems are likely here.

• No battery, bad contacts. Contacts may become damaged if the computer is dropped or severely shaken.
• The battery is faulty and therefore will not charge. The battery does not charge due to a faulty external power supply or damaged connectors.
• Malfunction indoor unit nutrition.

As you can see, there is very little that can be done at home to repair a laptop.
