The laptop screen does not turn on but the laptop is working

Reasons why the laptop does not run on battery

The battery is a consumable item that has a limited number of charge / discharge cycles. Over time, the battery capacity decreases, so the average battery life is 2-3 years.

In addition to the shelf life, there are other reasons for the failure of the battery:

  • Oxidized contacts.
  • Mechanical damage to the battery due to dropping or shock.
  • Power controller problem.

Before replacing the battery, you need to make sure that your battery is really damaged or exhausted. First, remove the battery and wipe the contacts with an alcohol solution. Let the battery dry, put it back in the laptop and turn on the device. If the problem persists, try resetting your BIOS settings:

  • Unplug the laptop from the electrical outlet.
  • Remove the battery from it.
  • Press the laptop power button and hold it for 20-30 seconds to reset the residual voltage.
  • Without installing the battery in the compartment, connect the plug of the power supply to the laptop.
  • Turn on the laptop and enter the BIOS by pressing the key indicated on the start window (usually the Delete key, or F2).
  • On the “SaveExit” tab, select “Load Setup Defaults”.
  • Confirm the decision to reset the settings to the factory settings by clicking “Ok”.

  • Turn off the laptop by holding the power button for 5-7 seconds.
  • Disconnect the power adapter plug and replace the battery.
  • Turn on your laptop in the usual way.

If resetting the BIOS settings helped correct the situation, then in the notification bar you will see a charging icon and a message stating that the battery is filling with energy. By the way, using this method, you will at the same time check the performance of the power supply. If the laptop does not turn on without a battery, then the cause of the problem must be looked for in the adapter, which may be damaged.

If you are using any battery monitoring utilities, it is best to uninstall them as they may prevent the battery from fully charging. All the necessary tools are built into the operating system, so no additional software is required to charge the laptop.

All laptop manufacturers have dedicated utilities for battery recovery. Go to your laptop manufacturer’s website and look for a similar one. The essence of their work boils down to the following: you connect your laptop to an outlet and turn on this utility. Within a few hours (or within a day) it will restore the battery by fully charging and discharging. It is not recommended to use a laptop at this time.

If all else fails. then the problem is serious and you will need to replace the battery or repair the damaged power controller. It costs money anyway.

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 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.

Why the laptop won’t turn on?

Let’s determine the stages of loading the laptop until it is fully turned on. We consider that the operating system has been successfully loaded as full power on. There is a desktop image, the mouse and trackpad are working. To get to this point, the laptop goes through several stages:

  • power on;
  • initialization and appearance of the image on the display;
  • loading the operating system;
  • working operating system.

Laptop does not initialize

The laptop turned on, the cooler started up, the lights blinked, but then nothing happens. The cooler is noisy, but there is no image. Most likely the problem is in the display. First of all, read the article on how to connect your laptop to your TV. If there is an image on the external screen, then the problem is with the laptop display. Either the display itself is broken, or the cable that connects it to the motherboard.

If the display is working properly, then the following is likely:

  • problems with the processor, memory or video chip;
  • BIOS problem.

Laptop diagnostics and BIOS reinstallation are best solved in the service center.

What to do if the laptop turns on for a long time and a black screen appears

Black screen and laptop take a long time to turn on? This may not necessarily be due to part breakage. First, you should remember all the last shenanigans done with the device.

If the device worked intensively for a long time, then it is most likely overheating. In this case, the laptop needs to be repaired by a qualified technician. Perhaps new programs or games were installed before that. After that, a reboot was performed, and the laptop did not turn on, then these may be Windows errors.

However, first you should pay attention to whether the device is connected to power.

If the laptop does not turn on when using only one battery. Perhaps he is simply discharged and there is no point in panic. If the charge is in full order, then it is worth connecting the computer to the network.

After the device was connected to the network, it turned on without any problems, then the problem lies in the battery.

Perhaps it needs to be replaced with a new one. But if the computer still does not work, you need to check whether all the plugs are in place and whether they come off. A wire may have been pinched or broken somewhere.

It is recommended that you check if the outlet is energized. Each laptop has a special light that signals the battery charge and connection to the network. If all the lights are on and the device still won’t turn on, the problem might be something else.

It could also be a problem with the hardware settings of the device. In this case, it is not necessary to contact a specialist. The basic steps to troubleshoot this problem can be done with your own hands without anyone’s help. To do this, you must reset the hardware settings. The following guidelines will help you cope with this task.

Causes of malfunction

The reasons why the user cannot turn on the laptop can be divided into several categories. Among them:

  • the device could overheat, the result of this could be damage to the south or north bridges;
  • problems with the video card or processor;
  • also, the cause may be a malfunction of the loop, matrix or backlight;
  • the battery could fail, but this happens quite rarely;
  • the problem is in the hardware settings of the computer;
  • RAM crashed.
  • In the last two cases, you can deal with the disorder yourself at home.

    One or another part may fail and stop performing its functions due to:

    Broken battery

    The battery is not a vital part. Try to pull it out and insert it over again. If the laptop turned on, then the problem was precisely in the power module. You can work without it, but then, before replacement, the laptop will turn into a stationary one.

    Software problems

    A black screen is more often due to mechanical damage, but the following factors should not be excluded.

    If the laptop is not completely disconnected, but simply behaves strangely, then you can:

    • a) Roll back the system to the previous restore point. To do this, select the “Recovery” item in the control panel and follow the instructions of the Wizard.
    • b) Start the system in safe mode and reinstall the drivers.

    Broken processor

    The processor is the brain of the laptop. It is protected very reliably, so the situations in which it breaks down make up no more than three percent of the total breakdowns. Alternatively, replace the thermal grease, this will allow better heat dissipation from the processor.

    A sure sign that the time to update thermal paste has come is when the laptop turns on and then turns off after a few seconds. Overheating protection triggered.

    Laptop black screen does not turn on. why, long, what to do

    Almost every second Windows user is faced with a problem when the laptop does not turn on and at the same time only have to contemplate a black screen. We can say that this is almost the most common breakdown.

    However, everything may not be so serious and perhaps there is no need to run to the service center for help. First of all, you need to figure out the causes of the malfunction yourself. Perhaps you can fix the problem with your own hands, without contacting specialists.

    • mechanical damage;
    • careless handling of equipment;
    • overheating of the apparatus;

    Causes of malfunction and their solutions

    There can be a huge number of reasons why the laptop does not actually turn on. Many of them are quite simple and it will not be difficult to fix them on your own, but with some problems you will have to contact the service center.

    Let’s take a look at the main reasons a mobile computer might stop starting:

    • Power problems Hard drive problems
    • malfunction of the video card or chipset microcircuits;
    • incorrect BIOS settings;
    • malfunctions of RAM;
    • overheat;
    • errors related to the operation of the operating system.

    Comment. Very often, people who say that the PC does not turn on at all mean that Windows does not boot. This is not entirely correct reasoning, but it is popular among ordinary users.

    After update

    Problems may occur during the update. Failure to install updates correctly may cause the computer to stop turning on.

    In this case, the user can install a new version of the BIOS, drivers or patches for the operating system.

    The most difficult case is the inability to start the computer after updating the BIOS. This happens when the user tried to intervene in the process, for example, by restarting or shutting down the computer during it, or when using unofficial firmware.

    Of course, it will not be superfluous to reset the settings to the standard ones. This can be done by removing the battery for a few minutes or by closing the corresponding jumper on the motherboard. But as practice shows, this probably will not help to fix the problem. The only way out is to contact the service center for repair.

    In a situation where errors started after installing driver updates or Windows, you can simply roll back to a previous restore point from Safe Mode, reinstall the operating system, or return to the state it was at when you bought it, if this function is available in the model.

    After overheating

    Modern computers generate a lot of heat during operation. In case of severe dustiness or a malfunction of the cooling system, overheating may occur, after which some parts may fail. As a rule, it is impossible to solve the problem on your own, you will have to contact the service center for this.

    The main parts that can fail as a result of overheating:

    • CPU;
    • video card;
    • HDD;
    • north and south bridges.

    It turns on, but

    In some cases, the PC may turn on, but the download will stop at a certain point. At the same time, error messages may appear on the screen. In some cases, Windows does not start, in others it even fails to initialize.

    What to do if your laptop won’t turn on

    Laptops have become part of the life of a modern person. Like any other technique, they sometimes break. When it stopped turning on, then you should not panic, but you should find the cause and eliminate it. In most cases, you will be able to restore your computer to work.

    After cleaning

    There are situations when, after cleaning, the laptop stops turning on. The fan may start or a squeak may be heard. On some models, the indicators also start blinking.

    Cleaning a laptop involves disassembling it. The first thing to do is to disassemble it again and check the connection of all components, as well as the installation of the cooling system. It will be useful to pay attention to the thermal paste and the serviceability of the tubes that serve for heat removal.

    If the RAM modules were removed during the cleaning process, then you should try to remove them again, clean the contacts and reinstall them. You also need to check if the laptop starts with the hard disk and optical drive disconnected.

    It is worth paying attention to the sensor for opening the lid (display) when disassembling again. If not very neatly assembled, it may be out of place.

    If the following simple tips did not lead to results and the device still does not work, then you should contact the service center. It is possible that the elements were damaged by static electricity or some other problem occurred during disassembly.
