Reason 3. overheating of the video card
When the laptop boots up, but the black screen does not turn on, we can also sin on overheating and malfunctions of the video card. In laptops, video cards are implemented in two ways. they are built into the processor or into the south bridge, or as a discrete video card that is connected to a separate Mini PCI-e slot. Most often, discrete video cards fail due to a decrease in the efficiency of a cooling system clogged with dust. Also, the reason may be the deterioration of the properties of the thermal interface. a heat-conducting pad or thermal paste.
Diagnostics of such a malfunction in the service is usually carried out using a laptop POST-card or a known-good processor or video card. At home, you can only focus on signals from the BIOS, if they are.
When you have an integrated video card in the south bridge or in the processor, the problem can be determined by excessive heating. Reballing of the south bridge or the chip of the video card built into the motherboard used to be a frequent occurrence and just a disaster for Acer, MSI and even ASUS laptops. Currently, this problem is almost eliminated by manufacturers with the exception of defective batches of electronics.
Laptop Black Screen Won’t Turn On. Top 5 Reasons
Welcome to the blog! Today I will tell you what to do if the laptop does not turn on, you see a black screen, the coolers are working and the indicators are on. It turns out that the laptop itself boots up, but only the screen works. Here is my rating of the Top 5 reasons for a black laptop screen, based on personal experience. This top is suitable for notebooks from Asus, Acer, HP, Lenovo, Toshiba, Dell, MSI, Samsung and others.
Reason 2. failure of backlight LEDs or inverter
If your laptop displays a black screen when turned on, then you can often see the desired image on it in bright light. Most likely, the reason is the failure of lamps or LEDs of the backlight or inverter. The backlight inverter is a board for generating the high voltage required to ignite CCFL lamps or power a line of LEDs.
If you have an old laptop, the backlights will fail over time. They need to be replaced with new ones or with modern LED backlighting. Fortunately, now such kits for finalizing the backlight of a laptop or monitor are sold in abundance.
To repair the backlight of the screen, you will have to disassemble the display and change the lamps and inverter. LED backlighting most often fails in pieces or single LEDs. Miniature LEDs for these lines are freely available.
If only the backlight inverter is out of order, then they can be found on ebay and aliexpress. Faults in lamps, LEDs and inverter are usually found by visual inspection and less often by dialing.
Also, don’t forget to check the loop. going to the screen. In older laptops, it was often frayed when opening and closing the lid. In modern electronics, this issue is not so acute, but you should always check.
Reason 4. black screen and BIOS problems
When the laptop does not turn on and it is clearly visible that the black screen is on, and the video card is working properly, there may be problems with loading BIOS commands. This is often due to a dead battery or BIOS glitches. First, reset the BIOS by shorting the Clear BIOS pins or remove the battery (often CR2032) and close the contacts to which it was connected. Sometimes a rechargeable battery is installed in laptops. but they also lose capacity over time. After clearing the BIOS, you may need to configure it again. Most often, the default settings work.
It so happens that the EEPROM chip. in which the BIOS is flashed fails. Here you need a programmer. to confirm this by reading the byte and new ROM chip for repair. Before repairing, you need to find the firmware file on the official website of the laptop manufacturer. How to unsolder the BIOS chip, see the video.
Reason 1. switching display mode
The first reason for the screen not working when the laptop is turned on and the most annoying one upon detection, I consider switching the display mode. Many laptops have the ability to connect a second screen. be it a TV or monitor. So, by default, when you simultaneously press the Fn button on the keyboard and the button for switching the image receiver from the F1. F12 series, the video signal is sent from the laptop display to the external screen.
Most often, the buttons F4, F5 or F8 are responsible for this. all manufacturers have different ways. Depending on the video driver settings, the image will be stretched over two screens, duplicated or translated only to the second screen. So, if you press these buttons by accident, you can lose your peace of mind. You will have to run headlong into service or start disassembling your laptop. To prevent this from happening, first of all, check this option for the appearance of a black laptop screen.
Reason 5. motherboard malfunctions
The last and rarest reason for a black screen when you turn on your laptop could be a faulty motherboard. Here I include: malfunction of the secondary power supply system, microcracks in the soldering or liquid ingress on the board and connectors, burnout of the tracks and violation of the integrity of the motherboard.
If the circuit for the formation of secondary supply voltages can still be repaired by replacing the transistors and drivers, then burnout of tracks and chips of the board is a direct way to disassembly. But motherboards flooded with liquids are restored depending on the level of damage and the available equipment in the service.
This concludes my Top 5 Reasons for laptop screen not turning on. Hopefully now it is clearer to you what to do if you see a black screen when you turn on your laptop. Unfortunately, I have not found any suitable video instructions for a black screen when turning on the laptop without harmful advice. Someone advises to shake and blow on the battery, someone takes out a hair dryer and begins to fry the motherboard right in the case. This is NOT necessary. So we read the article and ask questions in the comments, on the forum.
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 a video 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.
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 might 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.
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.
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 where the problems have arisen. Let’s consider 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.
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, this 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?

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 on what to do if the laptop does not turn on. only a black screen, I have collected the most common causes and solutions.
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 you need 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 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, not 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.
What to do if the screen is gray when you turn on the laptop?
If the screen is gray, then, as already mentioned, most likely the problem is in the hardware.Diagnostics
- Disconnect the power supply unit from the outlet and from the device;
- Carefully remove the cover and take out the battery;
- Hold down the power button for 25 seconds;
- Now we connect the “battery” and insert the power supply into the socket.

Laptop won’t charge: 5 main reasons and more than 10 solutions
What is the reason that the laptop suddenly stopped charging? Can this be fixed without calling a repairman? This article discusses the 5 most common charging problems that users encounter, as well as ways to fix them on their own.
New laptop. the battery does not want to charge
Assembly-only devices have a pre-installed licensing system. In this case, the battery of a brand new laptop does not charge for 2 reasons: a factory defect or incorrect initialization of the battery.
- turn it off;
- disconnect the gadget from charging;
- remove the battery;
- hold the ON key on (20 sec);
- return the battery to its place;
- connect charging.
The only thing left to do is turn on the device and make sure it works correctly.
A couple more tips for those who have a removable battery. For example, an elementary method:
- completely disconnect charging;
- remove the battery from its compartment;
- press and hold the power key for 1 min.
Then you need to follow the steps sequentially: return the battery. turn on the charger. wait 15 minutes and turn on the device. All.
- When the device is turned on, turn off charging, do not touch the battery.
- Press and hold the power key until the device is turned off.
- Connect the power supply.
- Wait a quarter of an hour.
The procedure ends by turning on the device. Thus, the problem can be dealt with independently, without the involvement of a master. 3 more common problems and their elimination are discussed below.
Battery charge does not reach 100%
Most of the manufacturers of laptops develop and install specialized software on devices to monitor and control the consumption / condition of the battery. Most often, these “optimizers” are the culprits of incomplete charging.
In such utilities there are 2 modes of battery operation, the first of which saves energy and does not allow you to fully charge. Switching to the second mode will restore 100% charge. A radical solution is to disable or completely eliminate the utility.
If the last procedure did not help, then the matter may be in the natural wear and tear of chemical elements, failure of controllers, oxidation of contacts. In this case, you cannot cope with the problem on your own.
Overheating of the battery. causes, effects, solutions
The problem arises if the owner of the gadget did not monitor the cleanliness of the cooling system. As a result, the dust accumulates in a dense layer and the battery, along with the entire device, simply overheats. Also, this defect can occur if you use the device in stuffy / dusty rooms. In a hot season. this is one of the first reasons on the list why the laptop battery won’t charge.
How can you tell if your battery is overheated? When the device is turned on, it charges quite normally for a certain period of time, and then the message “battery is not charging” appears. This is a sure signal of its overheating. What are the solutions? First of all, it is necessary to clean the device from dust accumulations. To do this, it is worth contacting a laptop technician.
In addition, special laptop stands will save the battery from overheating. They help to cool the device as a whole, and therefore, extend the life of the gadget.
An important tip in the end: The laptop should not be placed on soft surfaces (such as beds or sofas), so as not to block the ventilation holes.
Battery connected. no charge
The age of the device and its manufacturer do not play any role here. Samsung, Xiaomi, Prestigio or other laptops are equally affected by this problem.
The defect is identified as follows. in the notification area next to the icon indicating the charge, a message is displayed with the text: “Connected, not charging.” Windows users (version 10) will read a slightly different message: “Charging not in progress”.
The first cause of the problem is software anomalies, which only a specialist can figure out. What can you do yourself? The universal method is to “reset” the BIOS.
- Turn off the device completely.
- Take out the battery.
- Disconnect the gadget from the network.
- Hold the power key on (1 min).
- Connect the device to the network (without battery).
- Press the power key and go to BIOS.
- Reset settings to factory defaults (menu EXIT. Load Defaults).
- Save changes and turn off the gadget.
- Disconnect the power supply cord from the laptop.
- Return the battery to its place, connect the charger.
At the end, it remains to turn on the device (user settings will be saved) and observe its operation. If everything is done correctly, then “Windows” will please the user with a message: “connected, charging.” In case of failure, it is worth studying the following sections of this material and apply other methods of eliminating breakdowns.
Laptop not charging? The software is to blame!
The creators of the devices often stuff devices with various utilities. Their purpose is to increase the performance and lifespan of devices. The flip side of the coin is that the battery charge does not reach 100% because of this. The same goes for the official software where the error has crept in. You can fight this by finding and eliminating unnecessary software.
- click “Start”. “Control Panel”;
- go to “Programs and Features”;
- choose unnecessary software (hint: it’s easy to recognize a software pest. its name contains the brand of the laptop);
- select it with the mouse button and press “Delete”.
Securing success is worth rebooting the gadget.
In the end, all of the above methods are effective in 90% of cases of troubles in charging a laptop. Even beginners can use these instructions to help the gadget get back to work. If, despite all the efforts, the charging does not work out, then the problem lies in the equipment itself: wear of the charger, lack of power, problems with connectors on the laptop, and more. In this case, only a wizard will be able to find out why a Lenovo, ASUS, HP or other brand laptop is not charging.
In this case, the following can be noted:
- Graphics adapter drivers are missing or not working properly, therefore there is no image.
- Incorrect BIOS options, due to which the motherboard does not describe a piece of hardware.
Such difficulties can be eliminated on your own
At startup, the screen is dark, the coolers are working, but the indicators are off
The reason for this situation is often an obvious glitch. In this case, it is enough to disconnect the power supply and remove the battery for a few seconds. After turning on the laptop, with a high probability, it will start as usual.
The second, least common reason is that the BIOS options are lost and the laptop cannot correctly find the attached hardware. In this case, you will have to reset the options “blindly”, since there is no image on the screen. Although it is possible that when the BIOS interface is turned on, the picture will appear.
To switch to this mode after restarting the computer, press the F2, F8, Escape or Delete key several times (which one depends on the model of the motherboard and the BIOS version embedded in it). After you hear a slight click, press the F9 key to reset the BIOS options, and then F9 to save the configurations and restart the device.
Screen is dark at startup, but lights come on
The fastest reason is that there is no image on the screen. As mentioned above, it is either the LEDs in the matrix backlight burned out, or the loop that connects the graphics adapter and the screen is frayed. If there is a discrepancy in the loop, then traditionally, when the angle of inclination of the top cover is changed, the image on the monitor may appear briefly.
To find out if the LEDs have burned out, you need to take a powerful flashlight and shine it on the screen. With good lighting, you can see the image.
A broken cable can be replaced, even without the help of others. Traditionally, a laptop is assembled according to a modular scheme: both the motherboard and the matrix have slots where the ribbon cable is connected. The most difficult thing is to get a suitable cable, especially if the laptop was released several years ago.
Burnt-out LEDs are not as frivolous a breakdown as it might seem. The point is that they do not change: the entire matrix is subject to change. This is not very expensive, since its cost can reach a third of the device, even if you find used components.
You can also connect an external monitor or TV set through the HDMI port, which is found in any modern laptop. If there is an image on the external monitor, it means a discrepancy with the laptop screen. If there is no image, one of the probable problems may be a breakdown of the video card, which, because of this, does not give a picture.
Instructions for diagnosing problems with food
The first thing to check is the outlet where you traditionally plug the laptop power adapter. Plug in any other device here to find if it works.
It is better to use a multimeter to test the power supply. The reddish pin must be inserted inside the laptop plug, where there is a connector for a similar pin in the accessory case. Place the dark pin against the outside of the connector. The operating voltage of the power supply is traditionally 15 to 20 volts. You can also use a similar power adapter. If at the same time the LED on the laptop lights up, indicating that the battery is charging, it means there is a problem in the adapter.
Some laptop models do not fit, if the battery fails, the cells are exhausted or the controller that checks the charge level has burned out. You can remove the battery and start the laptop from the power supply. If it turns on, it means a problem in the battery. It is unrealistic to repair it. just change it to a similar one.
And another reason that the laptop does not start may be trivial. the owner simply forgot to charge the battery. Try to charge the device and turn it on after a couple of hours. Cleaning the contacts with an eraser can also help. both on the battery itself and on the laptop.
If the laptop generally does not respond to pressing the power key, then the fastest thing is that it broke. An inoperative laptop, when trying to start, at least, should emit at least a faint click. You can try to fix the key, but for this it is already necessary to tear apart the laptop. The design of the part given to us is primitive, therefore the best repair option is its complete replacement: if something inside on the physical level is broken, it is already impossible to fix it.
Restoring Windows in Safe Mode.
- Turn on or restart the PC, and during boot, when the monitor is dark, hold down the F8 key;
- In the menu that appears, select boot Windows in safe mode;
- After that, you will be taken to a simplified version of the desktop;
- And now, without leaving the mode, perform all the same actions that are described in the first method.
What to do if Lenovo laptop won’t start
As mentioned above, a prerequisite for lags when starting a laptop can be at least some peripheral device that does not work correctly. Try to disconnect any accessories connected via USB ports. If there is a discrepancy in one of them, the laptop will start normally.
The main obstacles to turning on the laptop
They can be divided into 3 groups. related to the hardware of the accessory, power supply and software.
The most common reason a lenovo laptop won’t turn on is if the power outlet is not energized. The battery of the device may run out, but a new source of energy has not been found. Despite its simplicity, this is the last problem users pay attention to. It is enough to plug another device into an outlet to make sure that it works. If everything is okay with her, you should look for the problem elsewhere.
If you have a tester, you can check the voltage at the outlet of the cord that is connected to the outlet. It is also recommended to connect the unit by using a different cord. Everything is fine? So the reason that the lenovo laptop does not turn on should not be looked for here.
Make sure that the connector in the laptop where the power cord is connected is functional. To do this, slightly move the wire at the point of contact with the device. If there is fan noise or other sound, the problem is clear. If the device still does not respond, you must continue to search for the cause of the inoperability.
Try to remove the battery of your lenovo device. The laptop does not turn on sometimes due to a short circuit in the battery. If the device turns on after removing the battery, then this is the problem. You can also remove the battery and then reinstall it. Sometimes it helps.
Do not forget about the possible breakdown of the power button itself. Experience and some knowledge is required to troubleshoot this problem. You may need to contact a specialist.
In the event that the laptop makes a noise when the power button is pressed, its fan rotates, but the screen is still dark, the reasons may be as follows:
- faulty hard drive. the reason for its failure may lie in mechanical damage (when falling or hitting, the hard drive suddenly fails, in other cases, characteristic clicks or other extraneous sounds are heard before the breakdown);
- problems in the BIOS. they arise in the case of doing certain operations (flashing or changing settings in the BIOS);
- malfunction of the south or north bridge (caused by overheating as a result of contamination of the cooling system);
- exit from the slot of the RAM bar (occurs when cleaning or other manipulations with the laptop).
If the breakdowns that have arisen for simple reasons can be fixed on your own, it is much more difficult to get the laptop to work in other cases. When there is no practical experience in disassembling the device, you need to contact the service center. There, specialists will carry out a detailed diagnosis of the device and identify the reason why the laptop does not turn on. Lenovo is repairable just like other devices. Perhaps it is enough to clean the cooling system and replace one of the parts, as well as carry out other preventive measures, so that the device again begins to delight its owner with stable operation.
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.
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.
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 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 outlet 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.

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.
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
Reinstall the operating system on the laptop
Symptom: example of a situation:
When I start the laptop (HP), the HP icon appears, after which the message “Welcome!” (it should be so), then the inscription freezes and a blank black screen appears, then blue for less than a second and a window immediately appears where you can select either Safe Mode or normal Windows boot. If you select “normal boot”, then everything is repeated all over again (that is, a dark screen on a laptop) or the laptop turns off abruptly! Windows 7 if that.
What to do. That is, the computer turns on and successfully comes to boot the operating system. Most likely, there are no hardware problems.
If a black screen appears on a laptop when Windows starts, we recommend reinstalling the operating system. this is the best way to restore the boot.
To do this, just use a Windows 10 boot disk or a USB flash drive. The best utility for writing a USB flash drive, in our opinion. Rufus.
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.
When the laptop is turned on, the screen is black. 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.

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.
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.
