The Laptop Screen Goes Out But Works Itself

Power settings in Windows 7

So, you have the operating system Windows 7 and the monitor screen quickly goes blank, whether it is a laptop or a stationary computer?!

We go to the Power supply section. To do this, simply right-click on the power supply icon on the Taskbar (as shown in the screenshot below) and select Power supply in the context menu that appears:

If you DO NOT see the power icon on the taskbar, then click on the small triangle icon (in the picture to the left of the power icon) with the left mouse button and find the power icon.

You can enter the Power supply in the second way.

Start menu. Control Panel:

Next, select System and Security:

And Power Supply:

So, whether we entered the Power supply section through the Taskbar or through the Start menu, now in the selected power plan we click on the link with its settings:

And already here we can configure the way we need:

1. How long does it take to dim the display (monitor) or turn it off so that it goes out completely, as well as when it puts the computer into sleep mode and adjust the screen brightness.

over, for a laptop, this can also be configured separately: Here are the batteries or From the network.

And, of course, after changing the settings, you need to save them for them to take effect:

So, if your monitor (laptop) screen goes blank quickly enough, try here to increase the time in the appropriate parameters (when the display is dimmed and turned off).

2. Since we have “climbed” into these settings, then perhaps it will be interesting for someone to delve into the additional settings:

But, this does not concern the Raised Topic, so I will leave it for independent development, especially since everything is intuitive enough there.

The monitor screen goes off quickly. what to do

I received a letter asking that the monitor screen goes off quickly. verbatim:

Of course, there are serious problems with monitors, and finding solutions to such problems can be quite serious business. So in some cases, even calling a specialist is indispensable.

But, also in many cases, the monitor screen quickly goes out simply due to the installed power settings.

Therefore, first of all, novice users just need to pay attention to these settings, which we will do in this article.

Let’s talk about Windows 7 first, and then about Windows XP, so choose where you need to deal with the monitor screen.

Power settings in Windows XP

You have Windows XP operating system on your computer or laptop and you notice that the monitor screen quickly goes out?!

We go to the Start menu. Control Panel:

Further, at the very end of the large list, we find Power Supply. We go there:

First, we choose a suitable power management scheme (as shown in the picture below), since perhaps some of the proposed schemes may suit us in terms of parameters (or at least approximately it may fit).

And we configure the parameters as we need. In particular, if, for example, we believe that the screen goes off quickly in our laptop, then in the Disconnect the display column, increasing the time (after how long to turn off the display):

Do not forget to click on the Apply button and then on OK for the changes to take effect.

So, if we think that the monitor screen on our computer (laptop) goes out quickly enough, then first of all we go to the Power supply to adjust it there. And here it was shown how to do it in Windows 7 and Windows XP.

If you are faced with a situation where not only the monitor screen goes out, but the laptop screen turns off completely, you can go to the article: the laptop screen turns off. what to do.

The screen in the laptop goes blank when running on battery power

Probably any owner has noticed this feature: the laptop screen goes blank when running on battery power. While when connected to a network, the monitor is bright and contrasty. And everyone wondered why?

This is due to the power settings. The point of all this is to ensure that the laptop can work on battery power as long as possible. It is logical that the task can be achieved if the screen is not as bright as when working from the network. Therefore, the laptop display always becomes a little dim when the charging is turned off, and after some time of inactivity it turns off completely.

You can increase the brightness using the function keys, which are in any modern laptop. If you have them, but do not work, it is possible that you forgot to install the Corresponding Drivers if you reinstall Windows.

You can adjust the power supply itself so that when operating on battery power, the brightness of the laptop monitor always remains at the same level as when operating on AC power. It’s easy enough to make it that we will show you now.

Setting up the power supply

To begin with, open the “Control Panel” (we think that problems with this should not arise). In the window that appears, look for “Power supply” and click on it.

Before us will appear Possible power schemes, each of which can be configured separately and run as needed. One of THESE schemes will be active and used at the moment. To change its settings, click on “Power Scheme Settings”.

In the window that opens, we will see the main parameters due to which the laptop screen may go blank during battery operation. Because we are now interested in working “on battery”, then it is these settings that we will consider (for the mode “from the network” they are similar).

  • Disable display. here you can set the time period, through which the laptop display will completely turn off, but it itself will continue to work. To turn the monitor back on, just move the mouse, or press any key.
  • Puts the computer into sleep mode. time after which the device goes to sleep.
  • Adjust brightness. using the slider, you can select a constant brightness when on battery power. It is this setting that is responsible for the fact that the laptop screen becomes dim when we turn off the charging. If necessary, you can set the full power here. But do not forget that it will discharge faster in this case.

After you have made the desired changes, do not forget to click the “Save Changes” button.

Advanced Power Settings lets you adjust deeper settings. But without special need, we recommend not going there. In this article, we will NOT consider them.

We hope we helped you figure out why the laptop screen goes blank on battery power. If you still have any questions or something does not work out, you can ask them in the comments to this article and ask for advice.

Because of what the screen may go out?

If the settings and sleep mode have nothing to do with it, the following may be a prerequisite for a dying screen:

Operating system error, Windows crash. To solve this problem, you will need to reset the BIOS settings, and then reinstall the OS. If the dying screen became to them after a new version of the operating system was installed, you need to roll it back to the previous version.

The problem is in the power settings. For this reason, the screen goes out very often, as the laptop goes into power saving mode in order to extend the charging time and, accordingly, increase the period of use until it is completely discharged and turned off.

The solution is to select new settings in the “Power supply” section, which is located in the “Taskbar” or in the “Control Panel” / “System and Security”.

In the “Settings” section, you need to select a period of time after which the system will automatically dim the screen in order to save energy. Here you can individually adjust the brightness of the screen in operating mode.

The Power Options tab allows you to make an appropriate power plan active. It is rational to use the one recommended by the system itself. New settings will take effect after they are saved.

Dirty, dusty laptop. The laptop should be cleaned regardless of the state of the technology. Excessive dust accumulated in the laptop can cause the monitor to flicker and even darken.

Gathering of drivers. Often the laptop screen goes blank due to unstable operation of the card driver.

Reinstalling the driver may resolve the screen dimming or blanking issue. But there are cases when the card itself burns out, one of its nodes fails, or the power cable communicating the card and the power supply is damaged, which requires hardware repair, it is impossible to do it yourself without Special tools and certain knowledge and experience.

Infection of laptop with malware. Often, it is viruses in a laptop that can provoke a darkening of the screen during the operation of computer equipment. In order to cure a laptop and eliminate this problem, it is enough to install a high-quality licensed antivirus program on it.
Sometimes you just need to analyze in what situation, at what time, which causes the laptop screen to darken.

Perhaps this problem occurs due to the download / activation of a third-party application or program of doubtful origin. In this situation, it is advisable to clear the laptop of such programs.

What needs to be done to make sure of breakdowns?

First, you need to make sure the laptop does not automatically go into sleep mode. To do this, it is enough to feats with the mouse or leads the finger on the touchpad (touch panel). Secondly, if the screen is dim (but not black), the prerequisite may be a failure of the screen settings.

In this situation, you need to check the settings and restore the optimal ones for work.

The laptop screen goes out but works itself

Many budget (and often expensive) laptops have a problem when the screen goes blank while playing or typing.

Naturally, each user in this case has a question: why the laptop goes blank during operation and how can this trouble be eliminated, does not spend money on maintenance?

As an inexperienced laptop user, sometimes you can solve the problem of a dying screen without the help of a computer wizard.

When you may need specialist help?

There are a number of problems with a laptop, accompanied by a dying screen, which can only be eliminated by a master. These problems include:

Failure of a spare part that serves to illuminate the screen.

As a spare part, both the backlight itself and an inverter or a loop that transfers power supply to components can act. In the latter case, when the lid is closed, the screen blinks.

After diagnostics, the work to restore the screen consists in repairing or replacing a part.

Failure of the matrix, motherboard. This breakdown can be eliminated only at the service center by replacing the screen with a new one.

If you cannot find the cause of the breakdown on your own, you need to contact a specialist as soon as possible, since such problems can cause other breakdowns, the repair of which will be much more expensive.

Be sure to contact the service center master if the reason for the dying laptop screen is a technical or electronic component.

Regardless of whether the cause belongs to the hardware or software category, after an in-depth diagnosis, it will be identified and eliminated as soon as possible.

dirty laptop

The second most popular prerequisite is the accumulation of dust in the laptop. Most often, Asus owners meet with this situation. It was noted that immediately after cleaning, the device stopped extinguishing.

You can take the laptop to professionals for cleaning, but it is quite possible to handle it yourself:

    First you need to completely turn off the device, it does not have to be in sleep mode. It must also be disconnected from the network. Then the user will need to gently turn it over so that the cover is at the bottom and disconnect the battery.

Turning the laptop over and removing the battery

The next step is to remove the cover of the device. In some cases, it can be removed NOT completely, but only partially. You will also need a part where the cooler is located, which is needed so that the laptop does not overheat. The bolts in each model are different, it all depends on the manufacturer. They must be carefully unscrewed. Most often, manufacturers hide the fastening behind special stickers or rubber inserts. Usually the cooling system is immediately visible as it collects the greatest amount of dust.

Removing the cover on the fan

The disassembled device will look like this:

Laptop with covers removed

Since the user only needs a cooler for cleaning, it must be carefully removed. It is important to remember that you first need to disconnect the power loop.

Disconnect the power loop

Now you need to arm yourself with a brush and a vacuum cleaner. They need to thoroughly purge the entire case, paying particular attention to the corners and the radiator. It is a yellow or orange plate with many different slots. You also need to thoroughly purge the cooler itself. At the end of cleaning, simply brush off the remaining dust with a brush.

Dust-free laptop

This completes the cleaning process. It is necessary to attach everything back, namely the cooler (after reconnecting it to the power cable again) and the cover. All bolts must be reinserted and pasted over the existing stickers, attach rubber inserts.

The laptop screen goes out, but it works itself

The situation when the laptop screen goes blank is quite common. It is most often encountered by novice users who recently bought a device.

The laptop screen goes out, but it works

It is worth considering the most basic reasons for this problem. over, having familiarized yourself with them, you can easily fix them.

Incorrect driver work

It also often happens that some of the drivers does not work quite correctly. For example, if the card driver does not work correctly, then the screen may often go blank or work with some failures. It’s enough just to reinstall them to solve the problem with dim color and unreasonable fading.

You need to download them only from official sources, otherwise you can only harm your computer.

DriverPack Solution Program

If the user does NOT know which drivers he has on the laptop and which ones are available, then you can use the DriverPack Solution program. It will help you not only find the available drivers, but also update them to the most current version. It also needs to be downloaded from the official website.

    As soon as the user downloads it on the Internet, the application will start in the same way and will also independently scan the available devices. In the “Programs” tab there is a list of installed programs, but the “Drivers” tab will indicate the number of drivers that require updating.

The Drivers tab indicates the number of drivers to be updated

It is necessary to be named “Update all”, after which a window will open with a list of drivers, which, with the user’s consent, will be updated to the most current version.

Click on “Update All”

Experts recommend NOT to work on your laptop at this time, close all other files and applications, and let the program update the selected devices. On average, this procedure Takes NOT more than 20 minutes, depending on how long ago the drivers on the PC were updated.

Power supply problem

The most common prerequisite is the lack of a power supply setting. Dealing with this is very simple, just follow a simple aLGorithm:

    Go to the “Control Panel” and select the “Hardware and Sound” section from 8 thematic blocks. It includes viewing devices and printers, changing their settings and other functions.

We go to the “Control Panel” and select the section “Hardware and Sound”

A window with Multiple Tabs will open. In this situation, you will need the “Power supply” section, thanks to which you can make power settings.

A window should now appear “Selecting or Configuring a Power Management System “. These parameters control how the computer uses electricity. You need to pay attention to the scheme that is now active (there will be a black dot to the left of it). Next to it there is “Setting the power supply scheme”, which you need to name with the left mouse button.

We select “Setting up the power supply scheme”

In this section, you need to find out the time after which the laptop goes out. This is the time when the user is NOT behind his device and is NOT moving the computer mouse. It is necessary to set the time of activity that the user needs. Also in these settings, you can make the computer completely NOT kerosene.

Section with temporary actions

If the user has a laptop from the manufacturer Acer, then he just needs to simultaneously press the “Fn” and “F6” keys. With this simple step, the problem can be resolved. On second-hand laptops, you need to press other keys, which are indicated in the technical instructions for the device.

The reason is in the BIOS

If the above methods did not help, then it is likely that the reason lies in the outdated version of the BIOS. You need to go to the official website and see the list of updates. If so, the BIOS will need to be updated.

  • In this situation, the Q-Flash utilities have proven themselves well. It can be used by both novice and experienced users as it is very easy to use. I downloaded it from an official source, you need to restart your computer, since this application will open in the very BIOS settings. To enter these settings, you need to press the “F2” key at the very beginning of the boot (sometimes “Del” is required).
  • Go to the settings, the user will see the BIOS menu, in the left corner of which new information will appear, namely the name of the previously installed application. There is also a hint: to enable users, press “F8”. Press this key, the system will issue a confirmation request. You will need to press the “Y” key, then on “Enter”.

Press the “Y” key, then on “Enter”

A new window will open, the item “Save BIOS” must be pressed “Enter”. Experts strongly recommend NOT to skip this step, as in case of an undesirable result, you can return the previous version. Then you need to click on “Update BIOS”, and then proceeds to the next step.

Click on “Update BIOS”

If an old version of the program was installed, then the update process will begin at this stage. The new version will bring up a window asking where the user wants to install the BIOS from. The screenshot shows a USB flash drive, but you can use any media if you want. On this device you need to download the official latest version of BIOS in advance.

Choose from which device the BIOS will be updated

Now the system will ask again about the user’s confidence and update the BIOS. After his consent, the process itself will begin, which can be monitored in the settings. As soon as it finishes, the laptop will restart itself.

BIOS update process

viruses

Malicious applications often lead to various computer problems. However, statistics show that in this case, the reason lies in them rather rarely.

If the above methods did not help, you will need to resort to this method and make sure that there are or are not viruses. To do this, you need to run a scan with any antivirus

If it is not there, you will need to download it. Consider cleaning from viruses using the popular Avast antivirus as an example. There are both paid and free versions. In this case, and will be considered, for which it is not necessary to pay, but the user can install a paid option.

    You need to download the program from the official source, after which the “Welcome to Avast” window will appear. It is recommended to click “Typical installation”.

Downloading the program “Avast”

Once the installation is complete, you will be prompted to register. This can be done both at that moment and later while working with the antivirus. If this is not done, then the user will be able to use the program for only a month.

Choosing a method of using the program

Now the application will open, in the left column you will need to find “Scan computer”, after which it will launch either express scan (It takes a little time, but does not check the files very carefully), or full / intelligent scan (viewing all available files and applications, take longer). After choosing one of the options, the program will start Scanning and, if there are viruses, will offer to remove them.

Choosing one of the options for scanning

After getting rid of malicious apps, the laptop screen should stop blanking out.

If all else fails, then you will have to carry your device to the service center, where specialists will find and fix the problem.

Reason 2. failure of backlight LEDs or inverter

If your laptop displays a black screen when turned on, then you can often see the desired image on it in bright light. Most likely, the reason is the failure of lamps or LEDs of the backlight or inverter. The backlight inverter is a board that generates the high voltage required to ignite CCFL lamps or power a line of LEDs.

If you have an old laptop, the backlights will fail over time. They need to be replaced with new ones or with modern LED backlighting. Fortunately, now such kits for finalizing the backlight of a laptop or monitor are sold in abundance.

To repair the screen backlight, you will have to disassemble the display and change the lamps and inverter. LED backlighting most often fails in pieces or single LEDs. Miniature LEDs for these lines are freely available.

If only the backlight inverter is out of order, then they can be found on ebay and aliexpress. Faults in lamps, LEDs and inverter are usually found by visual inspection and less often by dialing.

Also, don’t forget to check the loop. going to the screen. In older laptops, it often frayed when opening and closing the lid. In modern electronics, this issue is not so acute, but you should always check.

The laptop screen went out but it works

Welcome to the blog! Today I will tell you what to do if the laptop does not turn on, you see a black screen, the coolers are working and the indicators are on. It turns out that the laptop itself boots up, but only the screen works. Here are my top 5 reasons for a black laptop screen, based on personal experience. This top is suitable for notebooks from Asus, Acer, HP, Lenovo, Toshiba, Dell, MSI, Samsung and others.

READ  How To Record Screen On Laptop

Reason 1. switching display mode

The first prerequisite for a NOT working screen when the laptop is turned on and the most annoying one upon detection, I consider switching the display mode. Many laptops have the ability to connect a second screen. be it a TV or monitor. So, by default, when you simultaneously press the Fn key and the button for switching the image receiver from the F1. F12 row on the keyboard, a signal is sent from the laptop display to the external screen.

Most often, the F4, F5 or F8 buttons are responsible for this. all manufacturers have different ways. Depending on the driver settings, the image will be stretched over two screens, duplicated or transferred only to the second screen. So, if you press these buttons by accident, then you can remain calm. You will have to run headlong to the service or start disassembling your laptop. To prevent this from happening, first of all, check this option for the appearance of a black laptop screen.

Reason 4. black screen and BIOS problems

When the laptop does not turn on and it is clearly visible that the black screen is on, and the cards are working properly, there may be problems with loading BIOS commands. This is often due to a dead battery or BIOS glitches. To get started, reset the BIOS to close the pins Clear BIOS or Remove the battery (often CR2032) and disable the contacts to which it was connected. Sometimes a rechargeable battery is installed in laptops. but they also lose capacity over time. After clearing the BIOS, you may need to configure it again. Most often the default settings work.

It so happens that the EEPROM chip. in which the BIOS fails. Here you need a programmer. to confirm this by reading the byte and new ROM chip for repair. Before repairing, you need to find the firmware file on the official website of the laptop manufacturer. How to unsolder the BIOS chip, see the.

dirty laptop

The second most popular prerequisite is the accumulation of dust in the laptop. Most often, Asus owners meet with this situation. It was noted that immediately after cleaning, the device stopped extinguishing.

You can take the laptop to professionals for cleaning, but it is quite possible to handle it yourself:

    First you need to completely turn off the device, it does not have to be in sleep mode. It must also be disconnected from the network. Then the user will need to gently turn it over so that the cover is at the bottom and disconnect the battery.

This completes the cleaning process. It is necessary to attach everything back, namely the cooler (after reconnecting it to the power cable again) and the cover. All bolts must be reinserted and pasted over the existing stickers, attach rubber inserts.

Reason 3. card overheating

When the laptop boots up, but the black screen does not turn on, we can also sin on overheating and card malfunctions. In laptops, the cards are implemented in two ways. built into the processor or into the south bridge, or as a discrete card that plugs into a separate Mini PCI-e slot. Most often, discrete cards fail due to a decrease in the efficiency of the cooling system clogged with dust. Also, a prerequisite may be the deterioration of the properties of the thermal interface. a heat-conducting pad or thermal paste.

Diagnostics of such a malfunction in the service is usually carried out using a laptop POST card or a known good processor or card. At home, you can only focus on signals from the BIOS, if they are.

When you have an integrated card in the south bridge or in the processor, the fault can be determined by excessive heating. Reballing of the south bridge or the chip of a card built into the motherboard used to be a frequent occurrence and just a disaster for Acer, MSI and even ASUS laptops. Currently, manufacturers have almost eliminated this problem with the exception of defective batches of electronics.

Incorrect driver work

It also often happens that some of the drivers does not work quite correctly. For example, if the card driver does not work correctly, then the screen may often go blank or work with some failures. It’s enough just to reinstall them to solve the problem with dim color and unreasonable fading.

You need to download them only from official sources, otherwise you can only harm your computer.

If the user does NOT know which drivers he has on the laptop and which ones are available, then you can use the DriverPack Solution program. It will help you not only find the available drivers, but also update them to the most current version. It also needs to be downloaded from the official website.

    As soon as the user downloads it on the Internet, the application will start in the same way and will also independently scan the available devices. In the “Programs” tab there is a list of installed programs, but the “Drivers” tab will indicate the number of drivers that require updating.

Why does the laptop screen go blank

Breakdown is widespread, describing which the SC clients inform the master that the laptop screen goes out. That is, the user operates the device in normal mode (reads an e-book or, for example, gets acquainted with the content of an Internet resource), and the computer display at this moment gradually goes out or completely turns off. Only after moving the mouse or pressing one of the keyboard keys, it is possible to restore the previous characteristics of displaying the picture on the screen. Why does this happen and why does the screen turn off on a laptop? The sources of the problem can be different: from an inoperative cooling system to a motherboard failure or a failed matrix.

Software and hardware causes of failure

The reasons that the screen on the laptop began to turn off. a bunch of. They come in software and hardware. In particular, the software factors include various failures in the operating system settings or errors that occurred during the installation and use of the corresponding utilities. Very often the laptop screen goes blank if the power saving mode is set to extend the autonomous use of the gadget. In order to increase the time-out, you should change the parameters in the settings. Sometimes the computer idle period is set in the operating system settings, the correction of which can help in fixing the problem. If none of the above has led to a positive result, then the malfunction, most likely, has a hardware background. the problem is in the hardware. Perhaps the CCFL lamp has exhausted its life or the card needs repair. Often, the reason that the screen turns off on a laptop lies in mechanical damage to the cable connecting the screen with the card.

What the user can do on their own?

It is important to DO NOT forget about saving the selected settings so that they work.

Seek professional help

If the actions described above did not help, then the computer may need to clean the cooling system. To do this, it is worth using the services of workshop workers, who will check the device for contamination, having previously carried out professional diagnostics. If the whole thing is in the dust accumulated on the surface of the working elements of the cooling system, and it is because of it that the laptop screen flickers unpleasantly, then service engineers will start cleaning the PC. However, if cleaning does not help, then something else may be the cause of the defect. For example, it is often necessary to update the appropriate drivers, scan the computer for viruses, or reinstall the OS. When diagnostics identify problems with a die or adapter, then only replacing the failed component will help. By the way, it is in the service center that you can purchase a truly original and pre-tested matrix of the desired modification.

Possible symptoms of malfunction and methods of their elimination

The laptop screen may go blank when the charger is connected to the computer. However, the system continues to operate and when the charger is removed from the socket, the display lights up again. The problem is solved by adjusting the BIOS settings. It also happens that the transistor on the motherboard burns out, which happens during a short circuit and also causes the effect of a fading screen. Often, non-original software becomes the culprit of what is happening, and after installing the software from the official site, the problem goes away. There are also known cases when the display turns off at intervals of several minutes and can only be turned on after entering the password. The issue is resolved by running the Power Troubleshooter utility. In this case, uninstalling the power management application can also help. However, the best solution in this situation is usually to roll back the system to the version that precedes the car problem.
