I turn on the laptop black screen what to do

Symptoms of a Bad Battery:

  • the charge level is incorrectly determined;
  • the indicator does not detect the battery;
  • When the power plug is pulled out, the laptop turns off, does not work on battery.

Decision. Contact a service center for battery diagnostics. Replace it with a new one.


Placing a laptop on our lap, laying it on a blanket, fluffy blanket or thick tablecloth, we provoke it to overheat, because the air inlets inside the case are blocked.

Decision. Use your laptop on a hard surface. We also recommend using a laptop cooling pad. Inside it there are fans that take cold air from the environment and supply it from below to the laptop. The flow of air from the laptop cooler cools the internal components of the device. The temperature drops by 5-15 degrees.

The stand has a slight inclination, it is more convenient and comfortable to work on the keyboard.

6 reasons why a laptop suddenly turns off

The laptop is clogged with dust All laptops are equipped with a cooling system, which is represented by a fan and a heatsink. In advanced cases, dust can reach a layer of 5-10 mm, which causes the processor and other components to overheat, and at the peak of the laptop overheating, it turns off itself.

The laptop spontaneously turns off during operation. unpleasant situation. This article describes several common causes and how to fix them.

The laptop is clogged with dust

The laptop is equipped with a cooling system consisting of a fan and a radiator. The fan blows around the radiator grill, which has many iron plates closely spaced for cooling. Dust gets stuck between them, forming a felt, the thickness of which reaches 5. 10 mm in advanced cases. Therefore, the processor, video card and other components overheat.

Decision. The best option. this is to contact the service center to avoid damage to parts. At your own risk, you can clean the laptop from dust yourself:

  • unscrew the screws on the back panel;
  • remove the cover;
  • Use cotton swabs to remove large pieces of dust from the cooling system. Remove its remains with a can of compressed air or a vacuum cleaner with a “blow-off” function;
  • clean the fan using the same can of compressed air;
  • put the laptop back cover back in place and screw it down.


Users often acquire viruses by clicking on spam links and going to questionable sites

Decision. Install a version of one of the antiviruses. For example, antivirus from Kaspersky, ESET Nod 32 or Dr.Web. Update its bases. Do a deep virus scan on your laptop.

Disconnects from the battery

Does it work normally from the network? The average battery life for a laptop is 2-3 years. Uninterrupted operation depends on the type of battery, capacity, operating conditions. At the same time, the average laptop lifespan is 6-7 years.

Damage to the motherboard

The main breakdowns requiring repair of the laptop motherboard are as follows:

  • malfunction of the input-output ports (USB, headphone jack, FireWire ports, etc.);
  • malfunction of the video adapter (built-in or external discrete);
  • damage to integrated devices (sound and network controllers, modems, etc.) due to electrostatic discharge or other causes;
  • problems associated with the cooling system (overheating and failure of bridges, video cards or processor);
  • the consequences of poor-quality power supply (failure of power controllers, reflow or burnout of power connectors);
  • mechanical breakdown or liquid damage (flooding);
  • incorrect user actions (self-assembly and disassembly of the device).

Decision. Repair or replacement of the motherboard is carried out by the specialists of the service center.

Recommendation: keep an eye on the general condition of your laptop, it will last you longer.

What to do if a black screen occurs when you turn on your laptop

If the laptop is not communicating with you, there can be many reasons for this. When you turn on the laptop. a black screen, first of all, pay attention to its hardware. For example, the power button does not close the electrical circuit, one or more microcontrollers on the motherboard are out of order, capacitors are swollen, a unit or portable power source is faulty. a battery.

It should be noted that these problems do not always require specialist intervention. When the laptop boots up, a black screen may indicate a breakdown of both hardware and software. Be that as it may, you should clearly know what could go wrong.

How to recognize a problem and fix it in a timely manner

When you see a black screen when you start the laptop and there are no character lines, the battery may not be powering its components. In this case, you need to put the battery on charge for an hour and a half.

In more serious situations, the battery may fail and not function at all. If this happens, you need to carefully disconnect it by removing the plastic latches, then connect the power directly. When removing the battery, disconnect the power to the laptop first to avoid possible electric shock.

READ  How to split laptop screen into 2 parts

The opposite situation may also arise: the battery is working stably, and the power supply is out of order. To determine this, charge the battery. If the mains voltage is functioning normally, but the charge indicator is “silent”, you need to perform a light test.

To do this, remove the power supply from the laptop, and, without disconnecting the plug from the outlet, close the block connector and the base of a small 3-5 watt bulb. Perform this action with rubber gloves on your hands. If there is no light on, check the cord. Perhaps, somewhere along its length, the insulation is damaged, and the inner core of the wire is broken. This cord must be replaced immediately. Modern power adapters allow you to replace the cable by simply removing the previous one from the corresponding connector.

However, if no obvious damage to the wire is found (there is a suspicion of a malfunction of the unit itself), you should contact a service workshop. Diagnostics and possibly repair of the internal parts of the adapter should be carried out by qualified specialists in this field.

When the laptop is turned on, the screen is black. The power button may not be energizing

To check the serviceability of the button itself, you should dismantle the upper panel part. This usually does not require a complete disassembly of the laptop.

Next, you need to check that the button normally energizes and closes the working contacts. Such work should be carried out either with knowledge of electrical engineering and skills in working with a soldering iron, or under the supervision of a repairman for electronic systems.

If, when the laptop is turned on, the screen is black and the button does not connect the necessary contacts, it must be evaporated and a similar battery inserted. At the end of the work, do not forget to screw the disassembled panel into place.

Motherboard problems

Another common reason that when you turn on the laptop a black screen and nothing is displayed is a malfunction of the screen itself or the motherboard. And if checking the monitor requires the knowledge of a specialist, then some removable elements of the motherboard can be sequentially disconnected. Then check the performance of the laptop without this or that element.

The restrictions apply only to the central processor, which is the main hardware link. The maximum that can be determined is the absence of the necessary thermal lubricant or the cleavage of the central core (crystal). The heat dissipating cooler may also be faulty, unless the cooling is water.

When you turn on the laptop, the screen is black. 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 you should do 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 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 widespread and often requires professional intervention. 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 roll back all the changes. For this, it is better to use an external monitor if it has an image on it:

  • 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”.
READ  The phone quickly goes blank the screen how to set up
  • Confirm the decision by clicking “Ok”.
  • Press F10 and then “y” to exit BIOS with saving configuration.
  • In principle, these actions can be performed blindly, because all commands in the BIOS are entered from the keyboard, without the participation of the mouse. After BIOS reset, disconnect the external monitor and check if the screen works.

    Fixing the problem yourself

    Attention! We are not responsible for your actions. This article is for informational purposes only and does not call for action.

    The first step is to make sure the laptop is charged and the battery is working properly. We 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 special tools and knowledge. Better with a similar, contact the professionals.
    • Press the power key and hold it for about 20 seconds to remove the residual charge and reset the hardware settings.
    • Reinstall the battery and try to turn on the laptop.

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

    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:

    • Video card 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.

    Screen check

    If the screen remains black when you press the power button, 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 he has a damaged matrix or cable, but you can hardly diagnose this yourself. But before asking for qualified help, try two more ways to fix the problem described below.

    Reinstalling the RAM module

    Another reason for the black screen is a faulty 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 do not have the appropriate experience.

    • Unplug the laptop and remove the battery.
    • Remove the screws that secure the RAM cover. If there is no 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.
  • Replace the board by sliding it into place at a 45 degree angle. Don’t forget about the clips.
  • Close the lid and try to turn 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 specialists who can correctly diagnose the cause of the problem and quickly fix it.
