Causes and solutions to the problem
Resetting hardware data
The first step is to reset the hardware settings. This is the most common cause of this problem.
We reset the hardware data in the following order:
- Disconnect the power adapter (charging) from the laptop case.
- Removing the battery from the battery compartment.
- Press and hold the power (power on) button of the laptop for at least 20 seconds. Hold down the power button for that long in order to completely remove the residual charge in the device. Provided the laptop is disconnected from the power supply.
- We put the battery in its place and connect the charger to the laptop.
- Turn on the laptop.
- Using the arrow keys on the keyboard, select the Normal Windows Startup item, then press the Enter key.
And now, finally, our manipulations are over.
Resetting BIOS settings
The problem with the appearance of a black screen (the screen of death, as users called it a long time ago) may be the reason that you changed the BIOS settings the day before. In this case, you need to reset these settings and return to the original, factory.
This action also has several iterations:
- As soon as we turn on the laptop, we immediately hold down the key called F10 and hold it for 10 seconds. So we get into the BIOS itself.
- Press the key again, this time F9, and then Enter. These manipulations return us to the standard H settings.
- Again press the F10 key and Enter in order to save the new settings.
- Reboot the device.
If these actions did not have any effect on the laptop, we proceed to the next, more complex, step.
The laptop does not turn on, a black screen appears. What to do!?
This problem is very common and occurs in almost every second seasoned Windows user. This frustration can arise for many reasons. You can deal with the problem on your own and often there is nothing complicated about it. However, if your favorite laptop was flooded with water the day before, such manipulations are unlikely to help.
Reinstalling the RAM module
Contact problems and a defective memory module are also reasons that prevent the image from being displayed on the display screen. This method can help even if the laptop was flooded with water the day before. But in any case, before work, you should make sure that it is thoroughly dried.
- Be sure to disconnect the laptop from the electricity supply. Removing the battery.
- We tighten the bolts holding the cover of the RAM compartment. It is better to group the bolts by size, so as not to get confused later. If the laptop does not have a separate compartment, you will have to remove the entire back cover. We do it very carefully.
- Since the RAM is held in place with just a couple of clips, it is not difficult to remove it. We carefully remove the memory from the laptop, blow through all the connectors. You can swap them if possible. We insert the memory bar back, fixing it tightly.
- We assemble the laptop in the same sequence as in the parsing, only the other way around. Do not forget to install the battery and connect the charger to the mains.
But, if this manipulation did not have any positive effect, one should resort to the next, last.
If your laptop is working, that is, all the sensors are on, the cooler is working, but nothing is lit on the monitor screen. This will already be a malfunction of a completely different kind. You need to connect an external monitor to the laptop (usually all laptops are equipped with connectors for connecting additional monitors). If a picture appears on an external monitor, but it does not appear on a standard laptop monitor, then we can safely assume that the faulty laptop screen is to blame for everything. In this case, you have a direct path to the service center.
We have a direct path to the website of your laptop manufacturer. There you should find the drivers section and indicate the exact model of your device. We find the archive we need in the list of drivers and download it. Following the detailed instructions that should be attached with the archive, we reinstall the BIOS. It is worth knowing: this should be done only as a last resort, because a malfunction can be in the laptop’s video card, and in the south or north bridges. If possible, it is better to take your laptop to the nearest service center.
I hope these recommendations have helped you “revive” your favorite laptop.
Let’s analyze the functioning of the monitor
You have a reason to think that the monitor is not working due to mechanical problems, in this case you need to find out how the video card works with the motherboard.
So, let’s connect a second display to the laptop using the HDMI input (VGA is possible). We turn on the computer. If after switching on the second first screen is working, then the monitor or backlight loop on the monitor is faulty.
Important: you can start starting your computer when you have already connected an external screen. To freely switch from monitor to monitor, you need to use the Fn and F8 buttons. Relevant for ASUS and other brands.
Further, we will carry out all operations to remove failures and errors in the settings and various programs with a faulty display using a second monitor (you need to take it from friends for a while) by connecting the monitor via the VGA / HDMI input.
How to boot a laptop into Safe Mode?
Quite often, the laptop reboots after turning it on and the PC screen simply does not have time to boot normally. At the same time, it is advisable to load it in safe mode:
- Before loading the device, you need to enter another boot method. the F8 button (sometimes the DEL button or other buttons of the F row are suitable for different models). It is best to look at the instructions for the motherboard;
- In safe mode, you need to choose one of 3 boot options;
- Then, we enter the OS in this mode;
- Also, you can enter the system in BR in other ways. For example, through the command line “cmd” and “msconfig”. These applications are launched if you enter these labels through the “Start” search.
The laptop screen does not turn on, the screen is black, but the laptop is working.
The laptop screen does not turn on the screen is black, but the laptop is working. Everyone can face this, but what to do? Consider the reasons, because there are a lot of them. If the monitor does not light up, this does not mean that the laptop has malfunctioned. “Newcomers in a similar situation for the most part rush to the service center. But, the fact is that most of these troubles with a black screen can be fixed by themselves. So, first, the user must reset the hardware settings, and then look for the causes of this problem.
How to remove possible faults in the operating board?
The computer must be cleaned of dust. But, if such cleaning was carried out incorrectly, then it is quite possible that your laptop will turn on, but the screen will not function.
Also, this action can occur if you installed the RAM card incorrectly. Failures are possible both with RAM and with the functioning of other loops. In any case, you will need to disassemble the laptop and find out how exactly you connected everything.
An error in the operation of the operating board could occur if you accidentally spilled water on your keyboard or simply increased humidity in your room. To solve this problem with RAM boards, we will perform the following operations:
- You need to turn off the charging and battery;
- Remove the laptop cover where the operating board is located;
- If your microcomputer does not have such a compartment, it is advisable to disassemble the device completely;
- Next, you need to bend the board mount carefully;
- We take out the operating board itself, if there are several of them, we take out everything;
- We blow all elements with compressed air. The main thing is that it is dry and clean;
- Have you noticed signs of oxidation on the elements of the board? Don’t forget to clean them;
- Next, all the strips need to be installed back into the PC and secured with special clamps until you hear clicks.
After completing these operations, we collect all the elements back. Do not forget to screw the unwound parts back. If the operation of removing the planks could not help you, it is quite possible that other parts will fail. Quite often the loops break, perhaps a slight short circuit or the backlights just break. in this case, you need to contact the master.
Black screen with cursor
When the PC overheats, some of its devices are turned off. For example, the same monitor. It can turn off in full screen, or some part of it. Due to overheating, the video card turns off more often than others. If so, you need to turn off the device and cool it.
Usually, the temperature is checked using either AIDA64 or Speccy. Check the temperature preferably once 2 times a week, or at least once.
These programs show the temperature of other parts of the mobile gadget. When the device overheats, the display may also turn off:
- The CPU also has the ability to turn off the monitor when it overheats;
- When the motherboard overheats, various problems are possible in the PC;
- When the hard disk drive overheats, there are also problems with programs and utilities on the PC;
When errors occur in settings or a failure in the functioning of the computer, the only method of restoring programs to a failure is to boot the computer in safe mode (BR).
You need to install a working BIOS version
If your second screen works fine, but your computer screen refuses to work, also disabling the settings and returning to the factory settings BIOS could not help, in this case it is advisable to reflash the BIOS.
It is possible to update the BIOS in different ways:
- Using the “MS-DOS” option;
- Using the OS;
- Without entering DOS and starting the computer.
The easiest way to update the BIOS is to use third-party software. But, it is more correct to manually go to the main resource of the creators of your motherboard and simply download updates from this site.
The main thing is to create a backup copy of the OS or at least a restore point before installing the BIOS. When you start installing BIOS without an access point, your system may crash and you will lose all settings.
Getting started troubleshooting
So, before our actions with the laptop, it is advisable to reset the hardware settings of the device. With a high percentage of probability, this can help you remove the black screen:
- Turn off the minicomputer and pull out the cord from the socket;
- Then, take out the battery from the device;
- Press the power button for 25 seconds;
- Next, you need to insert the battery back into the computer;
- We connect the charging;
- Then, turn the laptop back on.
After you reset your hardware settings, if your PC starts to boot, it will ask you what type of OS to boot. Choose “Normal Windows Startup”.
Also, this screen may appear due to problems with the BIOS. The BIOS is also easy to reset. So, you updated its drivers and reset the settings, but they did not help you. In this case, you need to disassemble the laptop.
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.
You should 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, before the breakdown, characteristic clicks or other extraneous sounds are heard);
- 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 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 terms of disassembling the device, you need to contact the service center. There, specialists will conduct 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.
The laptop has a black screen, but the coolers start
One of the varieties of the problem is when after booting the system nothing is displayed except for the cursor on a black background. This happens on older laptops and may be due to a too old BIOS version of the motherboard. Why does this situation arise:
Windows 10 or other modern next-generation operating system automatically downloaded and installed new drivers for the graphics card;
the power control circuitry embedded in these new drivers is not able to function normally along with the old motherboard resources;
when the device is started, the monitor cannot fully display the image, although everything else works fine. the sound of the system startup is heard, the coolers are noisy, the power indicator is on.
As a result, all that is visible to the user is a black screen and a cursor on it. If you have an older Acer or Asus laptop, you can try closing and lifting the lid, often enough for the picture to appear. But your best bet is to update your BIOS firmware. To do this, go to the official website of the laptop manufacturer, find the “Files”, “Downloads” or “Support” section, and then download the appropriate update file. It always comes with step-by-step installation instructions.
After turning on the black screen on the laptop. what to do
If, after starting the device, the indicators are on properly, the system boots, but suddenly at some stage a black screen appears, then the reason is most likely hardware in nature and is related to the battery. If the battery has failed, if there is a chance to partially restore it by applying a sawtooth voltage, but this is a difficult method. Easier to get a new battery.
This problem is often faced by owners of fairly old devices, whose battery is no longer able to fully hold a charge. If your laptop Lenovo, Acer or another brand is still new, then you should try to reinstall the system or immediately take the device to a service point.
Replacement of spare parts
If the POST card is not available, but there are spare computer elements, then try replacing the ones installed in the laptop with equivalent ones. Attention: do this only if you have a clear idea of how the laptop works, otherwise you can completely break it.
Change one element at a time and try to turn on the device. For example, RAM, hard drive and so on.
The first thing to check is whether the power plug of the device is tight enough and whether the wire is damaged on bends, and also whether the battery is charged. Surprisingly, such simple problems often confuse users. If everything is in order, then check the following aspects point by point:
Battery performance. Connect power to the laptop. The indicator should light up, notifying that the battery is charging. If it does not light up, then remove the battery and, using an eraser, clean the contacts on the laptop and on the battery, if there is a semblance of plaque or oxidation on them. Then use up the remaining charge by holding down the power activation button. Insert the battery and try to turn on the device. If it does not turn on, then it is likely that the battery is out of order.
The ramps may become ineffective due to, for example, liquid spilled on the keyboard. Then a black screen appears on the laptop. To check the RAM, you need to disconnect the laptop from the network, remove the battery, unscrew the bolts from the cover, under which the memory is installed. Remove the modules and use the same eraser to clean the contacts. Put everything back and try to turn on the device.
Next, you need to check the video system. Check that the ribbon cable that connects the graphics card or motherboard to the graphics matrix is working properly. To do this, you can connect a TV or a regular monitor to your laptop via HDMI or older VGA, DVI. If an image appears on another output device, then the problem is definitely in the backlighting of the laptop display. Only a specialist can replace it, this is a difficult task.

Also, a black screen on a laptop can mean problems with the operating system or drivers. Often, returning to a previous system restore point, resetting it (in the case of using Windows 10), or completely reinstalling it helps. Finally, you can try resetting your BIOS settings. This is done blindly, because the laptop turns on, but the screen is black. Press the power button, then several times the key to start the BIOS. After a few seconds, press F9 to reset the settings, then F10 to exit and Enter to save. Depending on which laptop model you have (HP, Lenovo, Asus, Acer, etc.), the algorithm may be slightly different. you need to press the right or left arrow to select Yes, or press the Y button to confirm. You can find out which button gives access to the BIOS from the instructions for a specific device.
Why the laptop won’t turn on (black screen) but the lights are on
The main groups of reasons why such a problem may appear:
Damage to the south or north bridge of the motherboard due to overheating or mechanical stress.
Broken graphics card or processor.
Breakage or loss of RAM.
Problems with the hardware settings of the device.
Faulty loops responsible for connecting the laptop matrix with the screen elements.
In some points, you cannot do without replacing parts, and in some you can do it yourself. clean the fans from dust, remove possible obstacles to air exhaust from internal components.
What to do if your laptop screen is black but it works
If the laptop is noisy, the lights are on, but the display is off, then you can try to reset the settings according to these instructions:
Disconnect the device from the mains, remove the battery and hold down the start button for twenty seconds.
Reinstall the battery, connect the power supply.
Turn on the device in standard mode. After that, the settings should be reset.
If it does not help, then it is reasonable to check the display for performance. Such a check has already been described above: you need to connect another output device (monitor, TV) through the HDMI, DVI or VGA port. If the image is displayed on it, then the loop or backlight problems are obvious.
You can also disconnect all external devices from the device. a mouse, flash drives, an additional keyboard, headphones, modems, and so on. Probably one of them conflicts and gives the indicated problem.
Why is the laptop screen black?
When turning on the laptop, a black screen may appear for software or hardware reasons. The user himself, especially if he is a beginner, cannot always solve the problem, so we have prepared a material designed to help with this. And if you prefer to trust specialists, then contact our company for laptop repair.
Additional methods for solving the problem
It is worth mentioning in the article a few more methods that are considered extreme measures. You have to resort to them extremely rarely, but this is not a reason not to talk about them.
You can check the operation of the laptop hardware at the time of boot using POST. a special card for self-testing. Its purpose is to determine the reason for stopping the download or the normal operation of any components, including the screen. POST cards are available for laptops, which can be connected to USB or miniPCI connectors.
When the card is connected, when the device is turned on, codes will be displayed on its screen, each of which signals which component is being checked at the current time. As soon as a problem is encountered, POST displays information about it on the screen and stops working. From the instructions attached to the card, you can find out the decoding of the codes.
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.
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.
Remove the laptop cover and check the fastening of the RAM modules
We advise you to check the tightness of the connection of the RAM modules with the slots of the laptop: if the RAM bar has moved away from the motherboard, it is quite possible that the PC will not turn on.
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.
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 loading the operating system. Most likely, there are no hardware problems.
How To Fix Lenovo Computer On But Black Screen, Dim Screen, Display Not Working
If a black screen appears on your laptop when starting Windows, 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.
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.
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 boot of the operating system on the 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
In this case, the following can be noted:
- Graphics adapter drivers are missing or not working correctly, so there is no image.
- Incorrect BIOS settings, due to which the motherboard does not detect a piece of hardware.
You can fix such problems yourself.
The basis that affects the operation of the device as a whole is its motherboard. If any of the components fails, the laptop may show signs of life. at least blinking indicators or making noise from the cooler. With a serious strip of the motherboard, the device becomes “dead” and does not show signs of life at all.
Replacement of this part is not always required. Often it is enough to rewire a pair of capacitors or the node is more difficult. for example, replacing a chip called the “North Bridge”.
Regardless of the breakdown, it is better to entrust the repair of the motherboard to specialists from the service center.
Among other problems, when a Lenovo laptop shows a black screen, there are the following:
- Peripheral devices connected via USB ports prevent normal startup.
- Monitor backlight LEDs are burnt out, so there is no picture.
- The cable is broken and there is no connection between the video adapter and the monitor.
Instructions for diagnosing power problems
The first thing to check is the power outlet where you usually plug your laptop power adapter. Plug in any other device here to determine if it works.
It is better to use a multimeter to test the power supply. The red pin must be inserted inside the laptop plug, where there is a connector for a similar pin in the device case. Place the black pin against the outside of the connector. The operating voltage of the power supply is usually 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, then the problem is in the adapter.
Some laptop models do not turn on if the battery fails. the cells are exhausted or the controller that checks the charge level is burned out. You can remove the battery and start the laptop from the power supply. If it turns on, there is a problem with the battery. It is impossible to repair it. just change it to a similar one.
And another reason that the laptop does not start can 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 does not react at all to pressing the power button, then most likely it was she who broke. An inoperative laptop, when trying to start, should at least emit at least a faint click. You can try to fix the button, but for this you need to tear apart the laptop. The design of this part is primitive, so the best repair option is to completely replace it: if something inside is physically broken, it is no longer possible to fix it.
Possible causes of breakdowns
There are some problems when the laptop does not turn on completely. Consider how to diagnose them and what can be done in such a situation.
What can be done at home
Another reason why the laptop may not turn on is the lack of contact between the motherboard and RAM. In this case, the cooler will work and the LEDs will be on, but even the motherboard splash screen will not start and you will see a black screen.
In this case, you will need to disassemble the laptop. Algorithm of actions:
- Disconnect the power supply and remove the battery.
- Using a Phillips screwdriver, unscrew the screws on the bottom cover, including the battery compartment. Some of them may be hidden under stickers or laptop legs.
- Gently pry off and remove the plastic keyboard cover that protects the buttons.
- Dismantle the keyboard by pressing a pair of slotted screwdrivers on the special slots on the side of the monitor. Disconnect the keyboard cable from the motherboard.
- Use a Phillips screwdriver to remove any screws you see. Remove optical drive.
- Remove the bottom cover. Disconnect the components that prevent you from reaching the RAM bar.
In laptops, the RAM is no larger than a pair of matchboxes stacked together. It looks like a PCB with several chips on it. This component is inserted into a slot parallel to the mother chamber at the bottom, from the side of the bottom cover. You can use an eraser or rubbing alcohol to clean the RAM contacts.
And since you’ve disassembled the laptop, clean up the dust at the same time. As a conductor of current, it can cause a short circuit and prevent the device from turning on. Blow out all the “insides” of the computer using a household hairdryer, vacuum cleaner or a can of compressed air.
It is not recommended to install metal nozzles. only plastic ones. When metal comes into contact with electronic components, static electricity breakdown and the failure of expensive parts are possible.
Black screen at startup, but lights come on
The reason is most likely 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 display is frayed. If the problem is in the cable, then usually when the angle of inclination of the top cover is changed, the image on the display may appear briefly.
To determine if the LEDs have burned out, you need to take a powerful flashlight and shine it on the display. In good light, you can see the image.
A broken cable can be replaced, including by yourself. Usually a laptop is assembled according to a modular scheme: both on the motherboard and on the matrix there are slots where the ribbon cable is connected. The most difficult thing is to get a suitable train, especially if the laptop was released several years ago.
Burnt-out LEDs are not as frivolous as they might seem. The point is that they do not change: the entire matrix must be replaced. This is a little 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 via the HDMI port, which is found in any modern laptop. If there is an image on the external display, then there is a problem with the laptop screen. If there is no image, one of the possible problems may be a breakdown of the video card, which because of this does not give a picture.
The main problems with turning on the laptop
They can be divided into 3 groups. related to the hardware part of the device, power supply and software.
Coolers can be heard, but the laptop screen is not working
So, you know what to do if your laptop won’t turn on. But there are also cases when it starts, but its screen remains dark. What to do in this case?
Take a close look at the monitor. Perhaps you still manage to consider something? If so, then the screen, most likely, is in order, but the backlight does not work. You can enable it using the hotkeys on the keyboard. Each model has its own and most users are well known.
2. Another way to check if the screen is working is to connect an external monitor to the laptop. If a picture appears on it, then there is no doubt and the cause of the malfunction is determined.
3. Often the problem is hidden in a discrete video card. This element sometimes overheats and breaks down. By the way, some video cards are prone to breakdowns more often than others. For example, nVidia graphics cards have a short lifespan.
To prevent such damage, do not hold the laptop on your lap or in any other position with the ventilation holes covered. It is advisable in such cases to use special stands that do not impede air circulation.
If your laptop is not a gaming laptop, then do not devote too much time to games on it. And one more thing. do not forget to monitor the temperature of the video card. If the reason is in it, then remove or simply turn it off. on some laptop models, switches are specially provided for this. With the missing discrete video card, your device will continue to work, you just have to temporarily say goodbye to some games.
Of course, the reason why the laptop boots up and won’t turn on can be more serious. For example, in some cases, the problem is with the processor or firmware, motherboard or memory. But you are unlikely to cope with such difficulties on your own.
The laptop does not turn on and shows no signs of life
The worst thing that an ordinary user of this device can imagine. What to do in this case?
These are the steps you can take yourself when your laptop won’t boot. If none of them led to the desired results, then the problem should be looked for in a non-working motherboard, broken internal contacts and more. And only an experienced master will help with this.
Turns on and freezes after the splash screen
Sometimes, for some reason, the laptop does not start in any way. And sometimes it still starts, you can see the initial splash screen and basic information about the device on the screen, and then the device freezes. Either nothing happens at all, or information appears about errors that interfere with the full operation of the machine.
- Don’t be intimidated. The most common reason for this is the BIOS settings. You just need to enter the BIOS and reset all parameters. “Load BIOS Defaults”. After that save and exit.
- Sometimes it happens that the laptop freezes, reports the detected error and asks to press a certain button. For example, “Press F1 to continue”. As a rule, after pressing it, it continues to turn on and then works as usual. And although such a solution to the problem is the simplest, you should not ignore the very fact of reporting an error. Most often this happens if the battery in the motherboard of the laptop starts to run out or the BIOS settings get lost. Please note that you need to contact the service center to replace the battery.
- Of course, problems with a laptop can be more serious. For example, malfunctions associated with the operation of the hard disk manifest themselves in a similar way. In this case, there is a chance to determine the presence of problems by ear. If the hard drive is faulty, then you will hear the engine trying to start unsuccessfully under a slight crackling of the heads.
- Another reason why the laptop won’t turn on is RAM. Some device models provide access to its brackets. You can try removing them and gently cleaning the contacts. If this does not help, then start the machine, leaving only one memory module at a time. In the event that your device has only one bar, then put it in another slot and start the device again. There is a great chance that these actions of yours will help solve the problem.
What to do if the laptop does not turn on: 6 main situations and ways out of them
No one is safe from laptop breakage. But the good news is that most of the problems that arise in the operation of this device can be solved. It is only necessary to determine the cause of the breakdown and its nature, and then act according to the situation. All laptop problems are either software or hardware. It is necessary to accurately diagnose the malfunction, and then you will already know exactly what steps to take to eliminate it.
So, why the laptop does not turn on and what to do?
The laptop is constantly rebooting or shutting down
If your device is constantly shutting down and rebooting, then it is most likely a serious hardware problem. Perhaps the fault is in the short circuit in the south bridge, which caused it to overheat. Or, dust has gotten into the cooler, which has caused excessive heating inside the processor. If so, the fan will run at high speeds, but it will still not cope with the problem. As a result, your laptop will periodically shut down and reboot. This will happen at a variety of times, regardless of external reasons. You are unlikely to be able to solve the problem yourself this time, so immediately contact the service center.
But before that, make sure it’s not a bad diet. If the laptop battery runs out, the device can turn on and then immediately shut down.
A message is displayed about the inability to start from the boot device
As a rule, we are talking about a variety of messages in English. If you are faced with this, then remove all flash drives from the device, and remove the disk from the drive. Restart your laptop. If your actions have not brought any positive result, then the problem most likely lies in the work of the hard disk. Such a malfunction can be of both software and hardware nature.
In the first case, reinstall Windows. If after that your laptop began to work as before, then this means that the problem was software and now it has already been resolved. If reinstalling the operating system did not save the situation, then it’s time to contact the service department, whose employees will solve this malfunction at the hardware level.
After loading, Windows shows the screen of death, errors on the black screen and reboots
Another fairly common problem is when, when you turn on the laptop, Windows starts to load, but then the boot is interrupted, and the device restarts. The screen turns blue or black and displays numerous error messages.
As in the previous case, the problem can be of both software and hardware nature. And again, restarting Windows will help to understand what exactly happened to your device. Reinstallation of the operating system can be started from a bootable flash drive. If you succeed in doing this, then the problem can be considered solved. If not, then you can’t figure it out without the help of specialists from the service center.
Thus, if the laptop does not turn on, then this is not a reason to panic. In many situations, you can diagnose and fix the problem yourself. You just need to analyze your recent actions with this device. For example, if you spent many hours playing a game shortly before the breakdown, then your video card is most likely overheated. Try a little and you will be able to bring your device back to life again.
