How to turn on a laptop if it does not turn on in the usual way
The laptop does not turn on and does not boot for various reasons. hardware or software. It often fails to start due to an OS problem, BIOS malfunction, or after malicious applications are running. Next, we will tell you why the laptop does not turn on, and also describe how to eliminate most of the problems due to which the device does not boot.
Boot Loader Repair
If, when you try to boot, the display shows that the operating system was not found at all, you just need to restore the bootloader. Usually, similar problems arise when installing a second, older OS. For example, when the computer already has Windows 8.1 installed, and you installed the “Seven” as an additional option, then problems with loading them are guaranteed.
To fix the problem, enter the following commands sequentially:
- bootrec / FixMbr. a new boot record is created;
- bootrec / FixBoot. new boot sector;
- bootrec / ScanOS. search for all installed Windows;
- bootrec / RebuildBcd. adds information about found operating systems to the boot repository.
After restarting, Windows should start.
The laptop does not respond when the power button is pressed
The thing that causes no signs of laptop life at all are mainly power problems. I can advise further to immediately exclude the obvious things, for example, check if the device is receiving voltage. To do this, just connect the power supply to the network. most adapters have a light bulb.
If it is on, then the device is working properly. The laptop also has indicators that light up to indicate that the device is connected to the network.
When the light is off and shows no signs of life, this indicates an inoperative power supply. Sometimes the lights are off due to loose connectors. It is quite easy to extend the life of a power supply unit. you need to turn on by first inserting the plug from it into the laptop, and then connect the device to the network. So the spark does not light up when connected, which is why the contacts fail more slowly.
In the case when all the indicators are on when turned on, the problem may be in other devices as well. I can advise you to follow these steps:
- Remove the battery from the laptop and connect the device to the mains through the power supply unit without it. If the laptop starts up, the light is on, then the exit is to buy a new battery.
- If the laptop does not show signs of life, replace the battery.
- Disconnect external devices.
If, after turning them off, the indication lights up normally, the laptop is working, connect external devices one by one. so it will be possible to determine what caused the failure.
Graphics card problems
If it was not possible to find signs of laptop life on the external device, but all the indicators are on, a frequent cause of failure is a discrete video card. Due to the frequent launch of “heavy” applications, games, poor operation of the cooling system and strong dustiness, video card devices overheat and quickly fail.
Therefore, to extend their life, do not work on a laptop sitting on a sofa or bed (this is how you close the ventilation grilles), and for “heavy” games, purchase a special laptop stand with built-in additional fans.
You can fix the problem either by replacing the burned out module, or simply by turning it off. If it turns off, then the built-in graphics will work normally, but serious games on the laptop will no longer work. Switching can be done in the BIOS by setting the Disable parameter for the burnt card. In addition to the described malfunctions, the device often does not boot due to the inoperability of the processor or motherboard.
Laptop won’t boot, but fan noise is heard
Sometimes the laptop will not turn on due to a non-working screen, although the device itself boots. The backlight may just not be on. To enable, you can use “hot” keys. Their usual combination is the Fn button, pressed simultaneously with F2, F4, F5, etc. depending on the model and manufacturer of the laptop.
Sometimes the monitor itself does not show promise, and instead of an image, all sorts of artifacts can be displayed on the screen.
To check if only he is really faulty, the laptop should be connected to an external monitor.
Incorrect BIOS settings
Another case. the splash screen lights up, information about the laptop can be displayed on the display, but then it shows an error message, the speaker starts beeping or nothing happens at all, the system does not boot. The main cause of these problems is incorrect BIOS settings. You just need to reset them to default. For this:
- Enter the BIOS by pressing the Del button (for the Award version), F2 or F10 (for AMI) several times in a row immediately after turning on the power, sometimes F1, F3, F10 or F12 keys are used to enter the BIOS.
- Find the line Load BIOS Defaults or something similar (the name may differ in different BIOS versions).
- Exit BIOS by saving changed settings.
If the system does not start again, you should pay attention to other laptop modules. their malfunction can cause the same problem.
How to connect an external monitor
To do this, you will additionally need a cable, it must correspond to the interfaces on the external monitor and laptop. Usually, new devices no longer have an outdated VGA interface at all, but modern HDMI is available.
I can further recommend the following order of their connection:
- connect the laptop and monitor with a cable;
- connect the devices to the mains;
- the monitor must turn on first, then the laptop.
If the image does not load normally on the monitor, set the transfer mode on the laptop by simultaneously pressing Fn and one of the F1… F12 function keys, depending on the manufacturer. It usually shows a schematic of a monitor and a laptop. This button is responsible for displaying the image. to a laptop, to a monitor, or feeds it to both devices.
The laptop turns on and does not boot further
The source of this problem could be the BIOS, or more precisely, its settings. Try to set the default settings.
This function may be in different places in different BIOS, but its name usually looks something like this: “default BIOS settings”.
It is also possible that after starting the system, you see the message “Press F1 to continue”.
Usually this problem occurs when a battery is installed on the motherboard (not the main battery), shows the wrong time or BIOS settings.
Another problem could be the hard drive. You can determine if it emits a squeak or pops.
There could also be a problem with the RAM. Maybe you just need to turn off RAM memory and clear contacts.
Laptop won’t turn on. constant restart or shutdown
Most likely, this is a hardware problem, not always, sometimes reinstalling Windows 10, Windows 7, Windows 8 or Windows 8.1 (depending on which one you use) solves it.
Hardware problem, may be due to high dust content in the processor. In this case, you may hear a loud fan noise and notice a constant reboot.
When you hear the sounds produced by the device, it is better than nothing. Silence can indicate the general and final death of the laptop.
Usually, if it screeches, but does not start, the sounds are produced by the BIOS, and thanks to them you can pinpoint exactly where the problems have arisen. Let’s take a look at the set of sounds in the BIOS Award system. AMI BIOS has a similar.
A short single beep means the system is working properly. After that, it should continue with a normal start.
Two short beeps are an encouraging sign. The system speaks of minor malfunctions.
Three beeps. keyboard error. A complex combination of 1 long and 9 short beeps indicates that the data cannot be read from the disk.
Reasons why the laptop does not turn on
Shocks, falls, moisture penetration can seriously damage the parts, as a result, after such manipulations, the laptop does not turn on.
There is one more basic problem. a broken power button, fix it to continue using it. Due to the broken power connector, you will also not be able to use the device.
Black screen on laptop and won’t turn on. what to do
As I wrote above, the reasons why laptops won’t turn on can be very prosaic, but unfortunately, this is not always the case.
There are times when a hardware failure occurs. then you have to take into account significant costs. A black screen in a laptop may be for this very reason.
If you hear the sounds of operating components when you press the power switch, connect an external monitor (maybe a modern TV) to the VGA or HDMI jack. This procedure will bring you closer to figuring out what makes only a black screen see.
If the image appears on the external screen, it means that you do not need to change the video card. it works and interacts correctly with the monitor. In this case, you need to check your operating system settings.
Perhaps the screen was simply turned off, and the connection to an external monitor was activated. Pins in the case connecting the screen to the rest of the computer could also be damaged.
What if there is no image on an external monitor connected to the laptop? There are many signs of a graphics card failure. What to do in this situation?
The laptop does not turn on at all. check the power
Please note that this can be either an old or a new laptop. You press the “On” button, wait and it does not turn on. the device does not respond to our actions, even if we try to turn it on once, twice or 5 times.
Relax and start by eliminating the obvious reasons. Black screen in laptop can be caused by full battery discharge.
Then it is necessary to connect the power source, only sometimes the laptop does not turn on when working from the network, but this does not mean that it has already come to the end of its life.
You need to carefully check the power supply and socket in the laptop and even the electrical outlet.
You need to look at the cable, whether it is damaged, whether it is worn out and in what condition the plug in the power socket.
If you can, try running it on a different battery or PSU. The use of non-original, as well as cheap power supplies can sometimes lead to a short circuit. this is not always the case, but many confirm.
If the power supply is on and the laptop won’t turn on, turn it on again, but this time listen to how it reacts.
You need to check if the hard drive and fans are working. It is also worth seeing if the light diodes (indicators) are on, confirming the start.
often than not, when you hear the sounds of running components and the laptop does not turn on, or, to be more precise, you see only a black screen, it is very likely that you will need to replace the video card.
Laptop does not turn on. replace video card
A malfunctioning graphics card can be a serious problem. In this situation, it seems to us that the laptop is not working, but in fact it works, but does not display an image on the screen.
The idea immediately arises of replacing the old card with a new one. The problem is that on most laptops it is impossible to replace the video card yourself.
On many models, especially low-cost ones, graphics cards are integrated into the motherboard in the form of a BGA chip.
To replace it then you will not only need a lot of knowledge, but also the corresponding equipment.
The more expensive ones have separate graphics cards, but in this case, replacing this module will not be an easy job.
As a rule, replacing it without special tools borders on a miracle. Then the only option is to use the services of a professional, proven repair service.
Replacing the graphics card is so difficult that you may need to first remove the hard drive, Wi-Fi module and matrix, keyboard and GPU cooling.
As you can see, to get to the video card, you need to disassemble most of the device, and after that you need to fold it all.
There may be other damage that will cause your laptop to be unable to turn on. Sometimes the motherboard needs to be replaced.
7 proven reasons why your laptop won’t turn on
In the mobile age, few people still use desktop computers. they are increasingly being replaced by laptops HP pavilion / compaq / probook, asus, acer aspire, Lenovo yoga, Samsung, dell inspiron, MSI, Toshiba, sony vaio, packard bell, dns, emachines. irbis, prestigio, fujitsu, digma, haier, iru, acker, Xiaomi, fan, haier, 4good light am500, siemens, hi, alienware, brother, dexp, nek and others.
These are extremely useful devices, but they may also sometimes fail to turn on. What to do if the laptop does not turn on. just the black screen is on and that’s it?
It is not uncommon for a laptop to not turn on at all. I have seen such a defect in ASUS d541n, k750j, x551m, m50s, k52d, f3, f5r, x751m k50af x52n, k52n, n550, lenovo g500, g50, g505, g700, g580, b570e, g565 в590, np350, Samsung r540e laptops r425, r528, np300e5c, rv508, np350, HP pavilion g6, m6, dv6, g62, dv7, g62, g7, 625, g7 2300er, 6715, probook 4730s, omen, bcm943142y, compaq cq58, presario cqire e15, acer 571g, v3 571g, e531g, v5we2, toshiba l40w, satellite l300, emachines e642g, d620, dell inspiron 15, vostro 15 3558, haier hi133, msi vr330x, cx620, alienware m17x, iru jet 1521, sonyvood sve501s11 am600, dexp athena t132.
Only you should know that there can be many reasons why the laptop does not turn on. some of them are trivial and easy to fix, others are related to the graphics card and even replacing the motherboard.
Therefore, in my guide what to do if the laptop does not turn on. only a black screen, I have collected the most common causes and solutions.
Laptop won’t turn on. BIOS problems or hardware errors
The mobile computer starts up, the indicators are on, but after 1-2 seconds the device turns off. Most likely, in this case, a physical failure. Reinstalling Windows won’t help here.
Such symptoms indicate that something is wrong with the BIOS and may need to be restored.
If you are sure that the bootloader is not damaged, this indicates a problem with the motherboard or microchip.
There are many reasons: incorrect connection of a defective device via USB, processor overheating, short circuit, and others.
Writes that it is impossible to start from the boot device
There may be different messages in English, for example “Error loading operating system” or something similar, and then the laptop will not boot. First, remove all flash drives and disk from the drive and reboot. If it does not help, then the matter is either in the hardware or in the software problem of the hard disk.
The first one is solved by contacting the service center, but first you need to check that the problem is in the disk. The most affordable way is to reinstall Windows yourself. If it helps, then the problem was at the software level.
Constantly reboots or shuts down
The laptop can reboot indefinitely before attempting to boot Windows. This is a serious hardware problem, the south bridge may overheat, usually due to a short circuit in it. Most often this happens due to a breakdown via USB (remember what you inserted into the USB connectors).
Or processor overheating due to a dust-clogged cooler or a loose heatsink. But this is rare and is mainly accompanied by high fan speeds. In this case, the laptop may turn off or reboot at different times.
In the absence or poor power supply, the following picture may be observed: the device turns on, but quickly goes out due to a dead battery.
Turns on, shows a splash screen or writes something and hangs
It may be that the initial splash screen appears or information is displayed, but then the laptop does not start, it also beeps or writes about errors. The probable cause is problems with BIOS settings. You just need to enter BIOS and reset all settings to their defaults. In different versions, this item may be in different places, but the name is approximately the same “Load BIOS Defaults”. the keyword “defaults”. Then exit with saving the settings (“Save Settings and Exit”).
Please note that the system may be reporting some kind of error, but further loading is possible, you just need to press a button. For example, it can write “Press F1 to continue”, which means you need to press F1 to continue loading. This usually happens when the battery on the motherboard runs out (not to be confused with a large battery), the time and BIOS settings get lost. The battery must be replaced at a service center.
This is the simplest thing you can do yourself, because problems can be more serious, for example, a hard disk or RAM failure. With some skill, hard drive problems can be blindly diagnosed by listening to laptop When turned on, the working disk spins the engine and crackles for a couple of seconds, reading information. In case of problems, the engine may unsuccessfully try to start several times, or the heads crackle cyclically, trying to read something from the plates, while everything hangs on the screen.
Some models have open access to RAM sticks. If there is a suspicion of it, then you can try to remove the strips, carefully clean the contacts (see how to do this in the article “Why the computer does not turn on”). If it does not help, then leave one memory module (if there are several) and try to start. If there is only one bar, then move it to another slot.
Laptop does not turn on. solution to the problem!
Worked your laptop for a year or two and stopped turning on? Or maybe he didn’t work at all Well, such a nuisance happens, and in this article I will tell you what you can do in this situation yourself, and when you need to contact the specialists at the service center.
All problems with a laptop can be divided into two parts: hardware and software. Hardware problems are physical problems with the device, i.e. when repair is needed “by hand”. And the software can be solved on the spot, without getting up from the chair. This includes problems with BIOS setup, operating system and programs.
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 fault diagnosis is already half of the repair.
Fans are making noise, but the laptop screen is not working
Maybe the laptop itself turns on, but the screen does not work. Take a closer look at the monitor, maybe there is something there, but the backlight does not work. Define the hotkeys for turning on the backlight on your laptop and press them. For example, on many Lenovo models, these are the “FnF2” buttons.
The screen may really not work, and there are also various artifacts instead of an image. The surest way to check whether a screen or laptop is at fault is with an external monitor by connecting it to the VGA / HDMI output. If there is a picture on it, then the laptop screen will definitely not turn on. Read more about this in the article about stripes on the laptop screen.
Often the cause of the malfunction can be a discrete video card, especially for those who like to play games on a laptop. Due to a poor cooling system, dust / pollution thereof, or improper use of your “friend”, video cards overheat and break down faster. This is especially true for nVidia video cards (GeForce 8400M, 8600M, 9300M and others).
You don’t have to play with the computer on your knees, on your stomach, or in any position that blocks the vents. It is advisable to use laptop cooling pads. And in general, if a laptop is not positioned by the MANUFACTURER as clearly GAMING, then it is not recommended to play heavy toys on it for a long time, even if it pulls them. Monitor the temperature of your graphics card.
So, if the matter is in the video card, then try to pull it out, if the design allows, or turn it off using the switch that is present on some models. The beech can work without a discrete video card, demanding games just won’t run.
There may be more serious reasons: missing / not working processor or memory, broken BIOS firmware, non-working laptop north bridge (problems with the motherboard).
Windows starts to load, but everything is bad
It’s a kind of option that, as usual, Windows starts loading, but then the laptop reboots itself, errors appear on a black or blue screen. Here again, there may be a problem in the hardware, ie. hardware failures, and maybe software.
The surest way to test, again, is to reinstall Windows. “Lite” check option. start from a bootable USB flash drive with Windows. If the laptop with it behaves similarly badly, then it is probably rubbish, you need to carry it for repair. In general, the problem of loading Windows is a completely different story
The laptop does not turn on and does not show 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 that they are working. And on the laptop there is an indicator that signals the connection to the network and / or the battery charge.
Most often, the power supply does not work, or it functions inferiorly (here just try a similar one), bad contacts in the connectors, broken or bent wires. Look at the whole thing and draw a conclusion. at what stage the power is lost.
To avoid problems with the power connector, I advise for the future to insert the power plug into the laptop first, and then only the power cord into the outlet. By doing this, we exclude the possibility of a short-term appearance of a spark when the plug is connected, which spoils the contacts.
If everything “burns”, and the laptop still does not turn on, then the problem may not be in the power supply. Try again to remove the battery and turn on the device again without it, then after 10 minutes put the battery back. Also, disconnect all connected external devices (you can also disable the Wi-Fi adapter if the design allows).
Try to turn on, and if it works, then return the devices one by one, and so you can determine what was the matter.
If your laptop does not turn on and there is still a warranty, then immediately contact the service center!
Perhaps this is all that you can do on your own without disassembling the laptop, if it does not show signs of life at all or shows a black screen. serious reasons may include a non-working motherboard, a broken internal power controller, a south / north bridge, broken contacts inside the device, BIOS firmware failure, and others.
Let’s sum up
So what if the laptop won’t turn on? First, think about what happened, what was the last time they did it. If you played for a long time, then the video card or other chipsets of the laptop probably overheated and a qualified repair is needed here.
If you installed any programs, rebooted and that’s it, then there are most likely errors with Windows. The main problems that can be diagnosed and / or solved by myself, I described in the article. Finally, I would advise you not to make rash conclusions and not disassemble the laptop without proper experience.
Laptop hard drive defective
The laptop turned on, the indicators were blinking, and concise lines of system information appeared on the screen. That was the end of it. The operating system does not load any further. The hard drive is most likely to blame for this situation.
Why the laptop won’t turn on?
Let’s determine the stages of loading the laptop until it is fully turned on. We consider that the operating system has been successfully loaded as full power on. There is a desktop image, the mouse and trackpad are working. To get to this point, the laptop goes through several stages:
- power on;
- initialization and appearance of the image on the display;
- loading the operating system;
- working operating system.
Laptop does not initialize
The laptop turned on, the cooler started up, the lights blinked, but then nothing happens. The cooler is noisy, but there is no image. Most likely the problem is in the display. First of all, read the article on how to connect your laptop to your TV. If there is an image on the external screen, then the problem is with the laptop display. Either the display itself is broken, or the cable that connects it to the motherboard.
If the display is working properly, then the following is likely:
- problems with the processor, memory or video chip;
- BIOS problem.
Laptop diagnostics and BIOS reinstallation are best solved in the service center.
Laptop won’t turn on
Option 1. We connect the power supply, but the indicators do not light up. The laptop does not respond when the power button is pressed. The problem may not be with the computer, but with the outlet. We are trying to connect something to it, for example, a table lamp.
If the socket is working properly, then we check the power supply. The best way. use a serviceable power supply. If the outlet and power supply are working, then the problem is with the laptop. Either the power controller or the power circuits on the motherboard are faulty. Such repairs require qualifications and components, so it is better to go straight to the service center.
Option 2. When you connect the power supply on the laptop, the power and battery indicators light up. This means that the power supply is working properly. But the laptop does not respond to the power button, the cooler and hard drive show no signs of life. Unplug the power and leave the laptop for 2-3 minutes. Then connect the power. Should help.
Problems with the RAM appear similarly. Disconnect the computer from power, remove the memory modules from the slots, and then reinstall them. You can install the module in another slot, if available. If the laptop has two memory slots, then check their serviceability one by one by running the laptop to one memory module. The check will show whether the problem is in the memory modules or in the slots. If the memory fails, then we buy a new module. Otherwise, we take the laptop to the service center.

Use Safe Mode to boot your laptop
I have a black screen problem. At night I put the laptop into sleep mode, in the morning I turn it on: the laptop has a black screen and the mouse cursor runs if you move it.
I went to reboot the laptop, everything is fine with the Windows icon, but the black screen, I wanted to reinstall Windu, I chose it from the USB flash drive. all ok but again a black screen. I pulled out the battery, tried to return Windu to its normal state, knocked out an error. What to do if your laptop screen won’t turn on?
Symptom: When you turn on the laptop, you see the Windows logo, but as soon as the boot is completed, a black screen with a cursor appears. The desktop is not displayed, while you can go to the task manager.
How to fix a black screen:
A small but effective method if you cannot restore the operating system boot on a laptop in the normal startup mode is to enter the OS through safe mode. The fix method works with Windows 7, 8 and 10.
- Turn on the laptop by pressing the power button.
- Immediately after turning on, hold down the F8 key on the keyboard (after initializing the BIOS, before loading the operating system).
- From the Select Action menu, select Troubleshooting.
- On the Diagnostics menu, go to Advanced Options.
- The laptop will restart again, a menu will appear.
- In the Boot Options menu, among the additional boot options, select Safe Mode.
- Wait for the OS to load in Safe Mode.
- If booting is successful, try uninstalling unnecessary programs and drivers that could theoretically lead to a system crash.
- Reboot your PC normally.
Useful link (if suddenly it did not work out according to this instruction): Turn on Windows Safe Mode
Contact the service center
It makes sense to perform all of the above actions only if you have special skills in laptop maintenance. Otherwise, contact a reliable specialist.
Laptop matrix not working
Your monitor may not work. that is, the laptop matrix is out of order. It can be replaced by specialists in a service center or in a repair shop in your city.
Remove conflicting drivers on the laptop and replace with working ones
the laptop started giving a driver error. when I started the game, I turned it off. the laptop worked fine, came in and again. then pressed the button and turned it off, then restarted it. now the laptop does not boot, black screen, does not light up at all. everything works except the screen 🙁
What to do. Boot Windows into Safe Mode and uninstall conflicting drivers. Go to the developer’s website and download the latest drivers for your operating system version. Instructions on how to do it.
It also makes sense to contact the developers with this problem or look for a solution to your problem on the video card developers forum. Judging by the description of your problem, the black screen on the laptop is caused precisely by the driver conflict.
Check if the hard drive is detected in the laptop BIOS
If the laptop does not boot and you still see a black screen, try going into the BIOS (if it boots) and check if the hard (SSD) drive is detected.
Clean your laptop from dust
Finally, one more tip: If your laptop is noisy when booting up, dust it off. Sometimes, overheating of the computer directly affects the success of Windows boot.
Black screen when turning on laptop. what to do?
If your laptop does not turn on and you see a black screen after booting, this is not a reason to run to a service center. The article contains basic solutions, among them you will find a suitable one. If the guide does not help. ask a question in the comments, I will give you advice.
It turns on, but
In some cases, the PC may turn on, but the download will stop at a certain point. At the same time, error messages may appear on the screen. In some cases, Windows does not start, in others it even fails to initialize.
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 parts that most often cause problems with turning on the PC:
- south bridge;
- north bridge;
- graphics 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.
Power problems very often cause the PC to stop starting. Although the problem seems serious, in most cases it is quite easy 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;
- power supply problems.
Often, with such problems, the power indicator of the laptop does not light. 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 related to the battery. In some cases, if it does not work, then the PC stops turning on even with the network adapter connected. Usually, after pressing the power button, even the cooler does not work. Therefore, it is worth trying to start a mobile computer on mains 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 power supplies for laptops. Only adapters suitable for a particular model should be connected to a computer.
Power failure problems 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. You need to contact the specialists from our service center. Leave a request and you will be called back within a few minutes.
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.
Consider the typical problems that lead to the shutdown of the device without any indication from the user:
Samsung Laptop Won’t Power On Fix. Model R540
- malfunction of parts;
- software bugs.
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, you should contact our specialist immediately.
Viruses can lead to incorrect operation of the system, as a result of which the PC can turn itself off. To solve it, you need to download special utilities from the Doctor Web site or Kaspersky Lab, 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 removed 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 you need to replace the battery.
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:
- video card;
- north and south bridges.
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;
- Windows errors.
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 to the SETUP menu and loading the default settings, for example, by selecting the Load Setup Defaults option.
Errors in the work of Windows can lead to the fact that the OS does not 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.
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 may not initialize:
- malfunction of the processor, memory or video card;
- incorrect BIOS firmware;
- defects or damage to the south silt of the north bridge.
Regardless of the reason, you will have to carry the PC to the 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.
