The adjustment of the brightness of the Windows 10 screen has disappeared. Why not adjust the brightness on the laptop

The laptop display consumes more energy than other components, therefore, a decrease in brightness will help extend the battery life, just when working on a PC can deliver discomfort to the eyes dim or bright display. To make you comfortably work, consider how to configure the brightness of the screen on the laptop in Windows 7, 8, 10.

Laptop models are different, so the brightness setting may differ from the recommendations set out in the article. The material describes the total steps applicable to such manufacturers as Acer, Asus, HP, Samsung, Lenovoi others. There are enough ways to change the brightness of the screen, both standard and using third-party software. Let's consider all methods in more detail.

Tuning brightness using keyboard shortcut

Modern laptop models support changing the brightness of the screen with a combination of keys, which greatly facilitates this process. It is necessary to hold the FN function button (is at the bottom of the keyboard near the left Ctrl,), then press the up arrow keys up or right to increase the brightness, down or left to reduce. In combination with Fn, the keys from F1 to F12 can also be used.

All combinations depend on the model, the most common are shown above. Usually on the buttons used with Fn, a symbol resembling a sun is depicted. In the picture below, the Acer laptop keyboard is shown, where the FN + arrow combination will make the screen brighter, Fn + arrow left dim. If you can not find the Solny Symbol on the keyboard, check out the laptop manual to find out the hot keys to change the brightness.

Brightness shift through power settings

If your PC is assigned a combination of buttons, or you need to configure the screen brightness on a laptop in Windows 7, 8, 10 Use the power supply options. Press the tray to the battery status icon, then click the "Screen Brightness Setup" link.

If the battery status icon is not, then, indicate the presentation of "small badges". Among the elements, find "Power Supply" Press it.

At the bottom of the window, move the slider to a comfortable position. Changes will immediately apply and persist.

To make a detailed setup of the screen brightness in Windows 7, 8, 10 click "Setting the Power Plan" opposite the Planted Plan (see Screenshot above). Moving the slider, set the brightness of the plan for the battery mode and network. I advise you to save energy. Be sure to click the "Save Changes" button.

You can change the brightness of the screen on the laptop in the same way by clicking on the link of additional power parameters (see the picture above). Expand the "Screen" item, then the "screen brightness". Next, select "From the network", "from the battery" and set the percentage ratio. I recommend yet. After the changes, click OK.

Additional ways to change brightness

Go to the Control Panel Select the "Large Icons" view, find the "Windows Mobility Center" item. You can quickly run it in the seven by pressing the Win + X key combination. Next, you will learn to move the slider in the desired side.

Configure the brightness of the laptop screen in Windows 8 through the settings panel. To call it to click Win + I. Next click the brightness icon and adjust the slider. To call similar settings in Windows 10, click on the notification center on and adjust the parameters.

Programs to increase, reduce screen brightness

There is a huge amount of software that allows you to configure the brightness of the screen on the laptop. Many programs other than adjustment of brightness allow, contrast, color scheme and other parameters. These applications include:

1. ibrightnesstray.
2. Display-Tuner
3. Display Resolution Manager.
4. A lot others

For example, consider a simple Ibrightnesstray program that does not require installation. Download the archive with the application, unpack in a comfortable place. Next, run it, after which the iBright objectsstray icon will appear in the tray. Often the icon falls into the area of \u200b\u200bhidden icons, so you need to make the iBright objectstray icon on the visible place of the taskbar (see picture below).

Click the right button on the menu to call the menu, check Auto Start so that the program is automatically started when the laptop is turned on. The Change Screen Saver feature calls the screen saver window, EXIT turns off iBrightnesstRay, the remaining functions are described above.

Problems and solutions

After changing the brightness of the laptop, these settings are automatically saved. If the settings are not saved after restarting the laptop, it is likely that they are redefined in the power supply parameters. Go to the setting of the selected power plan and carefully determine the values \u200b\u200byou define.

They have noticed that the brightness level changes itself, then the automatic brightness adjustment option is probably enabled. To disable it, go to the additional power parameters of your plan, then disconnect the adaptive brightness adjustment and click OK.

Often, problems with brightness call video drivers. Typically, problems occur after updating video drivers. To solve the problem, do such actions:

1. Open Device Manager.
2. Find the monitor device open it.
3. Delete all monitors shown.
4. Next, update the hardware configuration to detect the monitor, and install the driver.

Some users face that it is impossible to adjust the screen brightness in any way in Windows 10. In this case, all the settings are trimmed, and the adjustment keys on the laptop also do not work. This article will describe the main causes of such a malfunction, as well as ways to eliminate it.

Universal PNP monitor disabled

If the settings that must be responsible for adjusting the brightness of the screen are absent at all, this is a sign disablepNP..

1. Then you need restart your computer And check if the desired settings did not appear.

Problems with video card drivers

One of the most common causes of such failures is the lack of the desired software for the video card. Several reasons for working failures:

CHIPSET drivers not installed

If I have recently been installed or reinstalling the operating system, then the problem may be in unidentified Drivers For chipset, it is especially true for laptops. They should be downloaded from the manufacturer's manufacturer's site.

It is possible on the manufacturer's page utilities only for earlier versions of the OS, in this case, you should download the latest available version The same bit that is installed now. These programs may be more efficient than those that are automatically installed.

TeamViewer blocks brightness settings

This utility, like some others, are used to remote PC access can set their software for the monitor. If the user has this or such a program, you should try the following actions:

Do not work brightness adjustment keys

If only special keys do not work, and in other cases the brightness is adjustable, then the problem lies in absence of special programs. It will be best to go to the site of the laptop manufacturer, download and install all utilities from there, even if there are no programs for a new system.

UPD from comment cartrelries:

If not helped

After upgrading to Windows 10., on laptops there may be a problem with automatic shift of brightness.
Laptop screen brightness windows 10 changes automatically to low And it can cause you irritation.
If you encountered this problem, you probably have already tried fix power outline and change adaptive brightness. (If so, immediately go to the end of the page to the item # 2 Replace videoer) if not, then start from the point # 1 .

1. Disable adaptive adjustment

Press right mouse button on "Start / Start" "Control Panel".

IN "Control Panel" Find "Power supply" Or if you have grouped mapping

On the screen "Power Supplies" Find "Setting the power scheme", go there.

In the power scheme parameters click "Change additional power options".

Make sure that we set the mode parameters active scheme to the right of the name of the mode will be a signature [Active]. Omit the slider and find "Screen".
In the drop-down list, check the parameters you need. Enable adaptive brightness adjustment [OFF]. (Both from the network and from the network)

If after this brightness continues to change, you need to replace the video card driver.

2. Replace videoer

Go to "Device Manager". Press right mouse button on "Start / Start" (Windows logo on the right at the bottom of the screen) and select from the drop-down menu item.

Find in dispatcher devices Video adapter You can have another, but most likely Intel (R) HD Graphic Family.

Click on it right mouse button And choose the item.


In the dialog box that comes out after clicking, you must select item Run the search for drivers on this computer


In the next screen, choose the screen Select a driver from the list of already installed drivers

To disable the annoying shift of brightness, select the list of proposed drivers Basic video adapter (Microsoft) (Microsoft) and click Further For its installation. The screen can blink, as when changing the screen resolution.


Upon completion in the device manager tooling in the section Video adapter You must have a basic video adapter, as in the figure.


After that, the system must stop changing the brightness.

Nervish, trying to increase the brightness of the laptop screen, but it does not increase, although recently the screen brightness was completely adjustable? How does the brightness do not work? And in the rustling of emotions, you have enough laptop in your hands and immediately notice that the screen has become noticeably brighter.

They involuntarily appear thoughts about some mysterious, but unkind third-party strengths that have chosen your laptop as an object of their maliciousness.

Or maybe something broke in it, and should I urgently drag it to the service? Having rushing you, everything is much more prose.

And now we will tell you where this unpleasant mysticism came from with brightness, and what to do with it, if she, as we, did not really like it.

So, adaptive adjustment of the brightness of the laptop screen in Windows 10.

Microsoft presented this feature with the new "Winda", because before you did not meet with her, and therefore the first acquaintance was faced with such an unexpected (and emotional) effect. However, many for the first time it seems that the brightness does not work ...

The automatic brightness adjustment function uses the built-in laptop (as a rule, it is a model from the new) the lighting level sensor nearest the surrounding space to it. Based on the data from this sensor (or sensors) in Windows 10, adaptive adjustment of the brightness of the laptop screen is performed. Simply put the system itself selects the level of brightness, depending on the brightness of the external lighting.

This is done, of course, with a good goal - to save the battery charge of the laptop, since the screen, especially on the maximum brightness, is known, it is element very voracious in terms of energy consumption.

However, as you already, probably, understood, such caring amateuries of the operating system is not always appropriate. For example, it is quite often that the laptop screen brightness is required, when you need to see and / or read something important and urgent on it. In addition, the built-in illumination sensors themselves are not technically perfect devices and sometimes work is not entirely correct (it takes place mainly when the laptop is moved), and then the brightness does not work.

In general, if, or rather, it will say when, adaptive adjustment of the brightness of the laptop screen you get tired (or because of the sensor as it is necessary "the brightness does not work"), then it can be turned off.

This is done as follows:

1: Click " Start ", Write in the search string" power Supply "(Only" electronic "), In the search results we find and click" Changing the power plan ", After that, the power plan settings window will open, which is currently acting on your laptop;

2: regardless of the title of the Plan, we find and click at the bottom of the settings window reference " Change additional power options «;

3: In the list of additional options we find and open the tab " Screen "(Click on the cross), and there - the tab" Enable adaptive brightness adjustment ", Choose" Incl " or " OFF "At your discretion and confirm the solution with the" OK «.

It is believed that adaptive adjustment of the brightness of the laptop screen makes sense when the machine works offline (the battery charge is still saved), and when the laptop is noted, it can be disabled. But your decision, of course, will be optimal for you.

Configuring the brightness of the display on laptops running on the Windows 10 platform is another Microsoft flaw. It happens that the setting of this parameter does not work at all when necessary. The problem when using new laptops lies in the implementation of the adaptive adjustment technology of the screen brightness, which many owners of new devices do not even guess.

Adaptive adjustment

When using advanced technology for the screen brightness, the illumination sensor integrated into the laptop is used. Based on incoming data and their processing on special, far from perfect algorithms, the "dozen" independently changes the value of the screen brightness depending on the amount of light falling on the sensitive sensor element. Such technology has been introduced, probably with the supply of "green" in order to save battery saving.

The named technology is far from perfect and not even brought by its developers to mind, but taking into account the many third-party factors that it is impossible to work out everything, this possibility is sometimes becoming a burden for the user. For example, Windows 10 does not allow you to change brightness manually, relying on the algorithm written by the developer. But this feature is easily disconnected in the "Power supply" applet.

• We enter "Power" in the search bar.
• Run the label "Changing the Power Plan" or go to "Changing the Power Scheme" through the "Power Supply" applet and click on the link displayed in the screenshot near the active scheme.

• In the list of options we find the "screen" and deploy it.
• The "Enable Adaptive Adjustment ..." parameter is transferred to the "Off" position.

• Confirm the solution using the "OK" button.

Bugs "Dozens"

Users who own laptops, more than once faced the problem of the impossibility of changing the brightness of the screen on their device. This feature relates to the final assembly of Windows 10 operating on some devices.

Although, rather, it is not WINDOVS itself, but the written drivers or the flaws of the system in the mechanism of interaction with the monitor or the graphical subsystem as a whole. But it is only guesses.

In fact, the exit from the situation is extremely simple - several clicks and a pair of phrases introduced into the search string. Correct this small misunderstanding through the Windows 10 registry.

• We enter the "regedit" into the search string or the text shape of the window that appears as a result of using the Win + R key combination.

• Click "Ctrl + F" or call the Main menu item "Edit", then choose "Find ...".
• In the search bar write "EnableBrightnes" and launch the registry scan with the "OK" key.

• We find the parameter "kmd_enablebrightnessInterface2" and call the editing window.
• We replace the value of the key to 0 and click "OK".

• We continue the search by using the "F3" key, and replace the values \u200b\u200bof the other keys with the same name.

• Restart the computer, and the option becomes available.

On the laptop to do it easily through the function key or the combination of the "Fn" key and any other (mainly from the F1-F12 series), the multimedia keyboard should also not cause questions. For a PC with a conventional keyboard, the brightness setup is performed using the monitor hardware keys, through third-party software or Windows 10.

Consider how the screen brightness level is configured by means of the "dozens" itself.

• Click "Win + I" to call the parameters of the system.
• Go to the System section.
• In the first subsection "Screen" we find the "brightness level" and change the value using the slider.
• How the setup is over, press "Apply".

Everything is extremely simple: it takes some time and knowledge.
