How to remove an error in BR?

Even after loading the computer into the BR, your laptop still loads automatically? In this case, you need to do “Windows Restore”. To do this, Windows needs to select a version of the system, to which it is easy to return: select the date at which the screen worked perfectly.

In the event that you managed to start the OS and the screen started working, then it is advisable to start updating the card drivers and BIOS. Even with a perfectly working monitor, it is advisable to update the drivers periodically, about once every 30 days. It will be easier for you if your PC updates them automatically.

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 card with the motherboard functions.

So, let’s connect a second display to the laptop using the HDMI input (VGA is possible). We turn on the computer. If after turning 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 switch freely 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 as a friend for a while) by connecting the monitor via the VGA / HDMI input.

Top Factors That Cause Black Screen

There are dozens of factors due to which such a screen appears. From here, to make it more convenient, we will divide them into categories:

  • The hardware of the computer is incorrectly configured;
  • There is a malfunction in the battery or charging;
  • The monitor cable is cut off, the backlight or matrix is ​​out of order;
  • The computer’s RAM or the slot of this board is out of order;
  • The card is out of order;
  • The system board is damaged due to overheating or damage.

Of course, NOT each of these user faults can be eliminated independently. For some problems, only the master is competent. Therefore, let’s take a look at which of these tasks a person can fix on their own. One of the most common problems is card failure. In order to find out if the screen is working, the fastest way is to connect a second external screen. Does it also not function for you? In this case, the fault lies on the map.

It is impossible to change various details in a laptop by yourself, and not having the necessary knowledge. In this case, you need to contact a specialist. Of course, you can start repairing your laptop yourself. But, the matter can go so far that you cause more damage to the computer than it was before your repair. The only way out in such cases is to buy a new monitor.

Good afternoon friends. 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 such troubles with a black screen can be eliminated by ourselves. So, first, the user must reset the hardware settings, and then look for the causes of this problem.

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. In this case, it is advisable to download 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 log in to the BR in other ways. For example, through the command term “cmd” and “msconfig”. These applications are launched if you enter these labels through the “Start” search.

Solving BIOS-related tasks

If we reset the settings in the BIOS, then this action can help you if, before this reset was carried out, the user in the BIOS performed certain actions.

So, let’s use the keyboard to reset:

  • Immediately after the laptop has booted, you need to press the DEL button;
  • We reset the settings with the F9 key;
  • Save the configuration with the F10 button;
  • We just have to restart our PC.

When you did not have time to press one of the indicated buttons and carry out these actions as quickly as possible, the BIOS settings may NOT change. And the computer screen will remain black because of this. In other cases, remove the CMOS (a small battery on the motherboard), which saves the BIOS settings, including when the PC is turned off.

How to remove Possible problems with the operating board?

I have already written in my articles, and I will repeat today that the computer needs to be cleaned from dust. But, if such cleaning was carried out incorrectly, then it is quite possible that your laptop will turn on, but the screen will no longer function.

Also, this action may 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 if the humidity in your room increased. To solve this problem with RAM cards, Let’s 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 microcomputers have comments of a SIMilar compartment, it is advisable to disassemble the device completely;
  • Next, you need to carefully bend the board mount;
  • We take out the operating board itself, if there are several of them, We take out everything;
  • All elements are blown with compressed air. The main thing is that it is dry and clean;
  • Have you noticed traces 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 I 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 strips 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.

The monitor stopped starting due to viruses

Does your screen still NOT launch? Then it is possible that your computer is infected with pests. In this case, you need to scan with your installed antivirus. If not, then we use the one-time Dr.Web cureit. Have you found any pests? In this case, you need to repair Windows or reinstall it.

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:

  • I 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;
  • Connect charging;
  • Then, turn the laptop back on.

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. In this case, it is advisable to download it in safe mode:

Laptop Running But Black Screen
  • 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;

  • Also, you can log in to the BR in other ways. For example, through the command term “cmd” and “msconfig”. These applications are launched if you enter these labels through the “Start” search.

Black screen with cursor

When the PC overheats, some of its devices turn off. For example, the same monitor. It can disconnect in full screen, or some part of it. Overheating causes the card to shut down more often than others. If so, turn off the device and cool it down.

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 central bank also has the property, when it overheats, to turn off the monitor;
  • When the motherboard overheats, the PC may have various problems;
  • 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 in a failure is to boot the computer in safe mode (BR).

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:

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 BIOS settings and 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;
  • Don’t enter DOS and start your 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.

The monitor stopped starting due to viruses

Does your screen still NOT launch? Then it is possible that your computer is infected with pests. In this case, you need to scan with your installed antivirus. If not, then we use the one-time Dr.Web cureit. Have you found any pests? In this case, you need to repair Windows or reinstall it.

Reasons why the screen remains black when you turn on the laptop

There are several reasons why you see a black screen instead of the desktop:

  • Map problem.
  • Damage to the motherboard due to overheating of the device.
  • Faulty loop or screen matrix.
  • Battery failure.
  • RAM failure.
  • Incorrect hardware settings.

The last three problems can be dealt with at home; it is difficult to diagnose a physical malfunction of laptop components on your own, so you will have to contact a service center.

Troubleshooting the problem yourself

Attention! We are NOT responsible for your actions. This article is for informational purposes only and has NOT won the Cup for Action.

The first step is to make sure the laptop is charged and the battery is working properly. Connect the laptop to the network (if it was running on battery power), wait a bit, and then try to turn it on again. If this time the screen lights up, then the problem most likely lies in the battery. Disconnect the laptop from the mains and try to turn it on from the battery again to make sure that the problem is correctly identified.

If the laptop does not work either from the mains or from the battery, try resetting the hardware settings:

  • Disconnecting the laptop from the outlet.
  • We take out the battery from the device. In most modern laptops, removing the battery requires disassembling the case, which requires a special tool and knowledge. Better with a SIMilar one Contact the professionals.
  • Press the power key and hold it for about 20 seconds to remove the residual charge and reset the hardware settings.
  • Put the battery back in place and try to turn on the laptop.

If these steps did not help to solve the problem and the screen remains black, then you need to check the physical health of the display.

Screen check

If when you press the power button, the screen remains black, but you can hear that the cooling system has started working and other signs of turning on the laptop are visible, then we try to connect an external monitor to it.

If a picture appears on the external monitor when the laptop is turned on, then the problem clearly lies in the laptop screen. Perhaps his matrix or loop is damaged, but you can hardly diagnose this yourself. But before you seek qualified help, try two more ways to fix the problem, described below.

The screen is black when the laptop is turned on. Reasons and what to do

In this article, we will give an answer to the question why, when you turn on (boot, start) a laptop, a black screen and what to do for you in a SIMilar situation. If it still beeps, then you will find the answer in the article Why the laptop beeps when turned on.

The laptop does not boot because the A black screen, or it starts up, makes a noise, but the screen does not turn on. the situation is not the most pleasant, moreover, it requires an immediate solution to the problem. This problem is common and often requires professional intervention, because K. One of the laptop components is damaged and needs to be repaired using special equipment.

Reset BIOS

If you updated the BIOS or changed its settings before the problem appeared, then you need to Rollback all changes. For this, it is better to use an external monitor if there is an image on it when you exit:

  • Turn on the laptop by connecting an external monitor to it.
  • Go to BIOS (Delete or F2 key at startup).
  • Press F9 or on the “Exit” tab select “Load Setup Defaults”.
  • Confirm the decision by clicking “Ok”.
  • Press F10 and then “y” to exit the BIOS with saving the configuration.
  • In principle, these actions can be performed blindly, because all commands in the BIOS are entered from the keyboard, without the involvement of the mouse. After BIOS reset, disconnect the external monitor and check if the screen works.

    Reinstalling the RAM module

    Another prerequisite for the appearance of a black screen is a malfunction of the RAM module. This is especially true for a situation when liquid got on the laptop, after which it stopped turning on.

    Important: The described actions are not recommended to be performed on your own if you have relevant experience.

    • Unplug the laptop and remove the battery from the laptop.
    • Remove the bolts that hold the RAM cover. If there is a compartment, then you will have to remove the back panel of the laptop.
    • Locate the RAM board and carefully remove it by bending the latches to the sides.
  • Blow out the connectors, clean the module from dust.
  • Put the board back in place by inserting it at a 45 degree angle. Don’t forget about the retainers.
  • Close the lid and try turning on the laptop.
  • If none of the described methods helped to deal with the black screen when turning on the laptop, then the best solution would be to contact a specialist who can correctly diagnose the cause of the problem and quickly fix it.

    RAM check

    The reason why the laptop won’t boot and the fan is running might be due to a RAM failure. For instance:

    • One of the planks came off due to the shaking of the device;
    • Due to the periodic switched on after arrival from the frost, condensation and oxides formed inside the RAM connectors;
    • Contact group of one of the memory lines oxidized.

    To check the status of the RAM, you will have to dismantle the protective cover on the bottom of the laptop.

    Important! This should be done only if the warranty period for the product has expired. One of the screws holding the cover is covered with a seal. It rips off when you try to unscrew, which automatically means the warranty is canceled.

    Before use, the laptop must be unplugged and the battery removed. After removing the cover (it can pry off at the edges and go up or move towards the edge of the case), access to the RAM strips is opened. To remove them, you need to move the side latches. After that, the bar rises 45 degrees and is pulled out.

    It is required to check the cleanliness of the connector, as well as the condition of the contact pads on the memory line. If there are traces of oxides, dirt, they are removed with alcohol, followed by a thorough rubbing with a regular school eraser for erasing a pencil. The strip in which the contact foil is wiped through must be replaced.

    Installing the ruler is done upside-down. The bar is tightly inserted into the connector (its protrusion and the notch on the line of the memory contact group must match) at an angle of 45 degrees until it stops. After that, the RAM line is slightly lowered. You need to make sure that the clips fit into their regular places, in the recesses on the side panels of the plank.

    Driver problem

    The case when the laptop is working, but nothing is displayed on the screen, may be due to an outdated BIOS version of the motherboard. In this case, the following happens:

    • A new generation operating system such as Windows 10 automatically installed new drivers for the card;
    • The power management scheme provided in the new software may not work correctly with the resources of the motherboard;
    • When you turn on the laptop, the monitor does not turn on, but the power button is on, there is a sound of cooling, logging in. this shows that everything is working fine.

    In this situation, the user sees only a black screen with a cursor. In Asus, Acer laptops of old revisions, for the appearance of an image, it is enough to close and reopen the lid.

    Contact problems

    The scratch disk in some laptop models is NOT rigidly fixed to a slide. A situation when, when turned on, the fan makes a noise, and the display has a black desktop screen, it may mean that the hard drive contacts are moving away. It can also be accessed by removing the cover on the bottom of the laptop.

    Before any work, the laptop is disconnected from the network, the battery is removed from it. After removing the cover, the hard drive is removed and inserted more tightly. If it is in the slide, you need to check the tightness of their fastening, if necessary, the disk is corrected for better contact with the connector.

    Complex problems

    The absence of an image on the display with obvious signs of system operation may mean a failure of the chip or central processor. Especially often this problem appears on Lenovo laptops.

    Built on single-chip solutions, they can come out of standing due to strong overheating or static discharge to the external port. Unfortunately, this problem is diagnosed only in a service center. Getting rid of her will cost money. In the case of Lenovo. very impressive.

    As a conclusion

    Many information sources recommend resetting the laptop’s BIOS if it does not turn on or there is no image on the screen. This step does NOT seem rational. The fact is that before installing the modern operating system Windows 10, Windows 7, the service engineer could switch the operating mode of the disk controller to ACHI. When you reset the BIOS, the IDE value will be returned. In this case, the system will not be able to boot under any circumstances.

    If you decide to overwrite the BIOS, you should refer to the instructions for the laptop. It contains all the data necessary to carry out this operation. Many laptops, including the already mentioned Lenovo brand, require pressing a special key or a combination of these to enter the BIOS. All the necessary information is stated in the instruction manual for a specific model.

    Broken loop or failure of the backlight system

    What to do if when the laptop boots up a black screen, the fan works, but nothing happens? The answer is SIMple: check the operation of the external output of the card. To do this, an external monitor must be connected to the laptop. This can be done using the connector on the side panel.

    If your laptop has a modern HDMI connector, you can plug it into your TV to test it. If the indicators are on, the coolers are noisy, and the image did not appear on the main screen and the external monitor. you should try to press the F6 button to forcibly switch to the connected image device.

    Software problems

    Newly installed software may be a prerequisite for malfunctioning card drivers. In this scenario, when the laptop boots up, a black screen is displayed with no clear sign of a normal login as a prompt sound.

    To remove recently installed programs, you need to boot into Safe Mode. For this:

    • When the BIOS is finished loading, the F8 button is pressed;
    • If the laptop does not display diagnostic messages, you can quickly press and release the button continuously immediately after turning on;
    • When a text term appears on the screen with boot options, you should select Safe Mode.

    After turning on the laptop in safe mode, you should uninstall recently installed programs. After rebooting, the system will be restored.

    Hard reset

    A hard reset might help when the laptop turns on but the screen is black. It is done differently on SEPARATE manufacturer’s models. HP offers detailed instructions both on its website and in the documentation for your computer. In general, you need to proceed as follows:

    • The laptop turns off and disconnects from the network;
    • The battery is pulled out;
    • The power button is pressed for 20 seconds or more. this is necessary to neutralize the remaining charge on the elements of the motherboard;
    • The laptop is connected by the charger to the network and turns on.

    For a double check, you can connect an external monitor or TV to the system. When turning on, you need to Follow: if the BIOS check lines appear on the device connection at startup, and there are images on the display, then the problem is in the laptop screen. A visit to the service center is required.

    Battery breakdown

    If the laptop does not start, not a single indicator is on, and the fans are not making noise, it is worth checking the battery status. For this, it is disconnected. The laptop is connected to a 220V network with a charger. If the system unit works in this mode, it means that an internal battery breakdown has occurred. It is enough to replace it to resume normal operation.

    Black screen when you turn on the laptop. today I will tell you what it can mean.

    By the way, it is precisely the black screen when the laptop is turned on that makes users go to service centers and lay out a lot of money for problems that can be fixed on their own. In addition, unscrupulous service centers like to deceive their customers, for example, they removed the battery and put it back in after a while, it is possible that the laptop will work as if nothing had happened, and the user who DOES NOT understand this will be told that the problem was hardware filling and will break a large amount of money. Therefore, do not hesitate, and try to solve the problem yourself, of course, with a little help from this article.

    First of all, you should remember that laptops and stationary PCs differ in many respects from each other, and not only in appearance. Laptop repair is a more laborious process, which can take a lot of energy from inexperienced users.

    Black screen when turning on laptop. A black screen appears when the laptop is turned on for several reasons:

    • There have been serious malfunctions in the operation of the north or south bridge, it is quite possible that the motherboard has overheated. In such cases, replacement of damaged bridges will be a lifesaver.
    • Broken card. When the PC is turned on, the windows boot sound may appear, the indicators may light up to indicate that the system is operating normally. The problem may be hidden in the backlight, as well as in the failure of the card. Most often, owners of PCs with built-in adapters complain about such symptoms. A new chip will be required.
    • Another possible option is a malfunction of the backlight lamp or matrix loop. You can check this option by connecting an external monitor, which will display the picture properly. In this case, the laptop will need to replace the flex cable, matrix or backlight system.
    • SIMilar symptoms can appear in case of malfunctioning with RAM.Try unplugging the power cord and battery (if not pulled out before), then Turn the laptop over and pull out the RAM and inspect it for oxidized and black spots. (read how to remove the RAM here.) If there are any, then most likely water was spilled on the laptop or it is another, no less serious hardware malfunction of your PC and I would recommend that you take it to a service center.

    If the RAM has no complaints, see how many slots for RAM your laptop has. (It is also possible that the operative is soldered on the motherboard and there are no connectors) If there is 1 connector, then after taking a good look at the bracket, insert it back and try to turn on the PC again. If nothing has changed, then it is possible that the operational itself is out of order and you need to buy a new one. But it’s better to take the laptop to a service center, where they can determine what happened. If there are two slots, then try pulling out the memory bar from the first slot, insert it into the second, close the lid and turn on the laptop without a battery. Perhaps the problem arose because the slot stopped working. If you have two sticks of RAM, try inserting each one in turn in different slots. Perhaps one of the planks is out of order. Did not help? A trip to the service center is inevitable.

    Also watch the laptop. excessive cooler noise, strange sounds, overheating. all this indicates problems with hardware filling or the need for hardware cleaning.

    The last is the battery, which has unexpectedly failed. Take out the battery and connect the laptop to power directly to check this version.

    A black screen when the laptop is turned on may appear under the influence of various factors. factory defect, careless handling, etc. The most reliable data on the performance of a laptop can be obtained using precision equipment, which is only in specialized service centers. Below you can see how the service center diagnoses laptops in which, when turned on, a black screen hangs. Good luck!

    What to do if, when you turn on the laptop, a black screen, but the light is on and the cooler is working?

    In this article we will talk about such an unpleasant symptom for any laptop as a black screen when turned on. over, the light bulbs can burn and even the cooler will spin. But there will be no image on the screen.

    Now you will learn what to do if you get into a SIMilar situation in order to try to bring the laptop back to life on your own at home.

    Cleaning contacts of RAM

    This is usually done easily. Unplug the laptop, disconnect the battery and turn it upside down.

    Removing the cover for installing memory in a laptop

    A cover should be present here, usually attached with a pair of bolts. It needs to be unscrewed and opened.

    You should see something like this.

    RAM strips in a laptop

    Small rectangular boards are RAM. They all need to be removed, metal holders should be tasted to the sides.

    Removing RAM in a laptop

    After removing the contacts, wipe the contacts with a regular eraser or alcohol, and if there are several memory sticks, try to insert them one at a time, each time turning on the laptop.

    The key is on the RAM bar. Wipe the contacts to the right and left to the end

    Reset laptop settings and turn on without battery

    The first step in such a situation is to disconnect the laptop from the network and then remove the battery.

    Removing the battery from the laptop

    Now without connecting it to the network and do not insert the battery, press the power button and hold it for about 30 seconds.

    Laptop power button to hold

    After that, connect the laptop to the mains without battery and try to turn on.

    Connecting an external monitor / TV

    If, after the result described above, there is, then you need to try to display the image on an external monitor or TV in order to check the performance of the matrix and its loop.

    VGA output in laptop for connecting an external monitor or TV

    To do this, you will need any monitor or TV, as well as a cable that connects the desktop computer to the monitor. It is called VGA or HDMI.

    HDMI output in a laptop for connecting an external monitor or TV

    After connecting a monitor or TV to your laptop, try turning it on. If the image appears on the monitor, then you have a problem with the matrix or matrix cable.

    Connect your laptop via an external monitor

    What makes this happen?

    There may be several reasons for this laptop behavior. Starting from the lost BIOS settings (UEFI) and exit from the standing matrix (matrix cable), and ending with serious problems with the motherboard (north, south bridges, card).

    Now you will learn what you need to do in stages to diagnose and fix this problem.
