Why do users need to know how to turn up the brightness on a laptop? There are several reasons at once, including both personal comfort when working with a laptop, and the need to increase battery life by reducing the energy consumption of the display.
Ways to change brightness:
Let's consider each method in detail so that you can evaluate which method will be more convenient to use.
All laptops have keys that, in combination with the Fn button, allow you to control some system functions. Usually these are buttons from the F1-F12 series, however, arrows can also be responsible for changing the brightness level.
Take a close look at the keyboard: look for buttons that depict the sun. There should be two such buttons - decrease and increase brightness. Press one of the found keys in combination with Fn (for example, Fn + F5) to check that the brightness level change function works.
If the hotkeys do not work or you cannot find them on the keyboard, then you can go the other way:
Mobility Center is designed to manage laptop components that affect battery life. Here you can adjust the brightness, volume, disable modules - in general, do everything to make the laptop work as long as possible without a charger.
If you do not like that the laptop changes the brightness level on its own depending on whether the adapter is connected or the laptop is running on battery power, then you can fix this situation through the Control Panel.
The changes you make will be applied to the current power plan. If you then specify a different power scheme, then you will have to adjust the brightness again.
If these methods do not work, and you do not have brightness control, then the cause of such a problem most likely lies in the unstable operation of the video card drivers. But there are other reasons as well:
Users, wondering why the brightness does not change, do not realize that the reason for this is sometimes the work of the TeamViewer program (a utility for remote computer control). The exact cause of the problem cannot be found, but judging by the forums (including Microsoft technical support), uninstalling TeamViewer often helps to fix the problem.
The most unpleasant situation is physical problems. If you dropped your laptop (or just use it for a long time), then there may well be hardware problems. It is unlikely that you will be able to diagnose them and eliminate them yourself, so you will have to think about going to a service center.
As for the hot keys and the video card, the solution here is simple - try to go to the laptop manufacturer's website and download the latest software for your model. For example, for the function keys of an ASUS laptop to work, you need to install the ATKACPI driver and hotkey-related utilities utility; laptops from other manufacturers should also have similar system utilities.
How to adjust the screen brightness on a laptop?
Master's response:
If you are an active PC user, and therefore spend a lot of time in front of the monitor, you probably often think about how you can adjust the screen brightness. Eyes can be very tired and ill, fatigue appears faster and irritability increases. All this can be easily solved by properly setting the brightness intensity of the screen. For example, you work a lot during the day, natural (and, if necessary, artificial lighting) is good enough. In this case, it is recommended to make the screen as bright as possible. These simple tips will help you significantly increase your productivity and minimize health problems. It is quite easy to adjust the screen brightness on your own.
All operating systems use special keys designed specifically to adjust the brightness of the screen. Use them and find the best option for your eyes. The Fn button is designed for just that. Press it and hold it for a while, while adjusting the “brightness” of the screen with another button with the symbol for increasing brightness. This combination of functions allows you to optimally organize the placement of buttons on the keyboard and guarantees quick access to frequently requested functions. This is the easiest and most affordable way for absolutely everyone to adjust the brightness.
Want to make it harder for yourself and learn more about the capabilities of your laptop? Go another, more difficult (compared to the previous one) path.
Select "Control Panel" if your laptop is running the Windows operating system. A service with the same name exists in other systems. Find the label (tab) "Screen". Click on it with the mouse. In the expanded window there is a slider for adjusting the brightness. Let's say you want the screen to become lighter. Move the slider to the right until you reach the desired limit in lighting.
Feeling confident and ready to "move mountains" in the settings of your laptop? You can safely use specially designed programs that come with laptops. These programs will definitely be equipped with powerful video cards. Their purpose is to change video card settings on the fly. The variety is determined by the model of the video card. Often they operate in the background, and the icon with their image is placed in the system tray. To enter the settings, click on the icon with any mouse button. A context menu or window will instantly open in front of you. Select the item with the settings and adjust the "lightness" of the screen using the slider. This is a little more complicated, but more interesting in terms of exploring the capabilities of your laptop.
There is nothing surprising in the fact that many users want the computer screen to display the highest quality and most acceptable image for the eye of a particular user in certain lighting conditions. This can be achieved, among other things, by adjusting the brightness of the monitor. Let's find out how to deal with this task on a PC running Windows 7.
One of the easiest ways to change the brightness of the screen is to make adjustments using the monitor's buttons. You can also solve the problem through the BIOS settings. But in this article we will focus on the possibilities of solving the problem with the tools of Windows 7 or with the help of software that is installed on a computer with this OS.
All options can be divided into 3 groups:
Now we will look at each group in more detail.
First, we will learn how to solve the voiced problem using a third-party program designed to control the Monitor Plus monitor.
Another program that can work with the settings of the monitor parameter we are studying is F.lux. Unlike the previous application, it is able to automatically adjust for specific lighting, according to the daily rhythm in your area.
Now we will learn how to solve the problem with the help of a program for controlling a video card. As a rule, this application is available on the installation disk that came with the video adapter and is installed along with the drivers for the video card. We will look at the actions with an example.
The settings of interest to us can be corrected using only OS tools, in particular, the tool "Window Color" In chapter "Personalization". But for this, one of the Aero themes must be active on the PC. In addition, it should be noted that the settings will not change everything displayed on the screen, but only the borders of the windows, "Dashboards" and menu "Start".
You can also change the specified monitor setting by using color calibration. But at the same time, you will have to use the buttons located on the monitor.
The advantage of working on a laptop is the portability of this device. This means that you can sit at the computer not only at home, but also on the street. Daytime street lighting complicates the work of the eyes somewhat. To correct the situation, adding the brightness of the laptop screen will help.
There are several ways to increase the brightness of your laptop monitor.
Keep in mind that increasing screen brightness will also increase your laptop's battery life.
In this context, it will also be useful to know how to change the time interval after which your laptop will automatically dim the screen in order to save battery power.
Setting this parameter repeats the path you have already taken: "Start" - "Control Panel" - "System and Security" - "Power Options". But now you are not looking down the window, but in the center, where several meal plans are presented. Each plan comes with a Power Plan Setup feature. By selecting this function, you can adjust the time after which the screen will automatically dim if the laptop is running on battery power or mains power. When the parameters are changed to your liking, do not forget to confirm them with the "Save Changes" button.
The ability to manipulate the color saturation on a laptop screen pays off. You not only save your eyesight and take care of your health, but at the same time ensure the maximum convenience and productivity of the workflow. Reducing the brightness of contrasts contributes to the minimum consumption of power and resources of your device.
The Windows operating system is equipped with all possible features for the convenience of work, but we do not always know how to use them. One of the easiest and quickest ways to increase or decrease screen brightness is to use the functionality on the taskbar. To launch the required function, hover over the battery display icon on the taskbar and right-click, select "Windows Mobility Center" from the context menu. A window will pop up, where the first item from left to right will be the “Screen Brightness” setting. By moving the slider, you will adjust the most pleasing contrasts for your vision.
Quickly, rather instantly, you can increase the brightness without using a mouse directly on the laptop keyboard. In each model, these keys may vary slightly, but the principle is the same. Find the Fn key and the up-down or left-right arrows. On the versatile arrows, the sun with a guiding pointer should be depicted. If you press the combination "Fn" + arrow to change the brightness of the screen, then you will get the desired result.
You can independently create and configure a power plan that will work according to the parameters you specify. The laptop itself will dim or resume screen brightness after a specified period of time. To create a laptop backlight brightness graph separately for mains and battery operation, proceed as follows.
If you cannot find the option you need, and the image is dull and inconspicuous, you may need to update the operating system, install drivers.
When setting the brightness level from the battery and from the network, you need to understand that the saved settings are valid only for the current power plan. In order for your settings to remain valid and no longer create discomfort, you must configure all three standard plans that are provided by default in every laptop.
Not so long ago, I ran into one most unpleasant problem - on all my laptops, the ability to adjust the brightness of the screen disappeared at once. Whether it's your favorite Fn keys, or the standard brightness slider in your computer settings. The very concept of “brightness” in the screen settings has disappeared and the main working machine has stalled in dark mode.
The way out of this situation, as it turned out, is quite simple - the problem lies in the drivers. After scouring the forums, I was able to find a few ideas that resulted in a simple solution. For normal operation of the brightness controller, you need to reinstall the driver ... no, not the video card, but the monitor!
How to do it in the easiest way?
That's it, kickbacks save our lives again!
Important! When using the DRP program, be sure to work in manual mode and expert mode! Otherwise, in addition to updating drivers, you will also get a ton of useless programs! To do this, when starting the program, check the box next to "Settings", select "Expert Mode", check the monitor driver and click "Install" at the bottom of the screen. More details in the screenshot below.
Detailed instructions for working with the driver package are available at the link:.
P.S.: when trying to find the cause of such glitches on one of the computers, I noticed that the monitor driver was digitally signed by TeamViewer. It is quite possible that the problem lies precisely in this program - it was installed on each of the computers being repaired. Might be worth contacting their tech. support.
Quite often on the forums they ask the question: Why doesn't the brightness control on my laptop work!? The problem is quite common, at first glance trifling, but in fact very unpleasant. Indeed, in this case, you will have to look either at an overly bright screen (which will instantly hurt your eyes and cause a headache), or at an almost dark one, where you can’t see anything. Today we will talk about the most common causes of the problem and what can be done to fix the problem of screen brightness not working on a laptop.
We list the possible reasons why the brightness on the laptop is not adjusted.
If you have an HP (Hewlett Packard) laptop, the Active Keys feature is often activated by default, thanks to which the top row of laptop keys works without Fn, and to use the standard F1-F12 keys, on the contrary, you need to hold down Fn. Hence the advice: try pressing the F key, which is responsible for adjusting the brightness WITHOUT pressing Fn. If the adjustment worked without FN, you can disable the Active Keys Mode function in the BIOS:
Lenovo laptops have a similar setting. By the way, by default, there is also often a quick access mode for adjusting brightness, volume, and other functions (without pressing Fn).
By the way, in Windows 10 you can adjust the brightness if you click on the battery icon in the taskbar and click on the corresponding button:
Adjust screen brightness on a Windows 10 laptop
At the same time, an undefined device may not be in the Device Manager! The driver required for the operation of brightness, volume, and screen mode switching may be called power manager, keyboard driver, hot keys driver, or quick launch buttons. Go to the laptop manufacturer's website, find your model, exact modification, select the current operating system and look for such a button driver.
There are two nuances here:
First, about how to correctly search for a driver for the current laptop configuration using HP as an example. For the same model can have up to a dozen modifications by different hardware.
Secondly, if you found your product on the manufacturer's website and did not find the current installed Windows in the list of supported operating systems, this is a problem. There may not be a driver for this OS at all. All you can advise here is to look for similar models from this year that support your version of Windows, and try installing the button driver (or Power Manager, Key driver) from it. Sometimes it is possible to pick up in this way.
Try to install Windows newer than the current one. For example, Windows 10 comes with a standard driver that can adjust the brightness on many laptops.
Therefore, here you just need to install the top ten, let it install all available updates and drivers and try how it will work with your hardware. For older models, you can try installing Windows 7.
Hello.
On laptops, a fairly common problem is the problem of screen brightness: it either does not adjust, then it changes on its own, then everything is too bright, then the colors are too weak. In general, directly "sore subject".
In this article, I will focus on one problem: the inability to adjust the brightness. Yes, it happens, I myself periodically encounter similar issues in my work. By the way, some neglect the monitor settings, but in vain: if the brightness is too low (or strong), the eyes begin to strain and get tired quickly (I already gave advice about this in this article:).
So where do you start solving the problem?
1. Brightness control: several ways.
Many users, having tried one way to adjust the brightness, make an unambiguous conclusion - it cannot be adjusted, something has “flew”, it needs to be repaired. Meanwhile, there are several ways to do this, besides once you set up the monitor - you can not touch it for quite a long time, and you will not even remember that one of the methods does not work for you ...
I propose to try several options, I will consider them below.
1) Function keys
The keyboard of almost every modern laptop has a . Usually they are located on the F1, F2, etc. keys. To activate them, just press the button. FN+F3 For example (depending on which button you have the brightness icon on. On DELL laptops, these are usually the F11, F12 buttons) .
function buttons: brightness adjustment.
If the screen brightness has not changed and nothing has appeared on the screen (no control) - move on ...
2) Taskbar (for Windows 8, 10)
In Windows 10, adjust the brightness very quickly if you click on the power icon in the taskbar, and then left-click on the rectangle with brightness: adjust its optimal value (see screenshot below).
3) Through the control panel
First you need to open the control panel at: Control Panel\All Control Panel Items\Power Options
4) Through the video card driver
The easiest way to open the video card driver settings is to right-click on the desktop and select graphics characteristics from the context menu (in general, it all depends on the specific driver, sometimes you can go to its settings only through control Panel windows) .
In the color settings, there are usually always items for setting parameters: saturation, contrast, gamma, brightness, etc. Actually, we find the desired parameter and change it to fit our requirements.
2. Are function buttons included?
A very common reason why a laptop does not work function buttons (Fn + F3, Fn + F11, etc.)- are BIOS settings. It is possible that they are simply disabled in the BIOS.
The choice of the section where to enter the BIOS depends on your manufacturer. Here (within the framework of this article) to give a universal recipe is unrealistic. For example, in HP laptops - check the System Configuration section: see if the Action Keys Mode item is enabled there (if not, set it to Enabled mode).
action keys mode. HP laptop BIOS.
In DELL laptops, the function buttons are configured in the section Advanced (extended): the item is called Function Key Behavior (two operating modes can be set: Function Key and Multimedia Key).
3. Lack of key drivers
It is possible that the function buttons (including those responsible for screen brightness) do not work due to lack of drivers.
Give generic driver name in this question (which you can download and everything will work) - it is forbidden (by the way, there are such on the network, I highly recommend not using it) ! Depending on the brand (manufacturer) of your laptop, the driver will be called differently, for example: in Samsung it is “Control Center”, in HP it is “HP Quick Launch Buttons”, in Toshiba it is Hotkey utility, in ASUS it is “ATK Hotkey” .
If you can’t find a driver on the official website (or there isn’t one for your Windows OS), you can use special utilities to search for drivers:
4. Incorrect video card drivers. Installing "old" working drivers
If everything worked as it should for you before, and after updating Windows (By the way, when updating, it is always, usually, a different video driver is installed) - everything started to work wrong (for example, the brightness adjustment slider runs across the screen, but the brightness does not change) - it makes sense to try to roll back the driver.
By the way, an important point: you must have old drivers with which everything worked well for you.
How to do it?
1) Go to control Panel Windows and find there device Manager. You open it.
Next, find the "Display adapters" tab in the list of devices and expand it. Then right-click on your graphics card and select " Update Drivers...«.
Update driver in device manager
Then select " Search for drivers on this computer«.
By the way, it is possible that the old driver (especially if you just upgraded an older version of Windows instead of reinstalling it) already on your PC. To find out - click the button at the bottom of the page: " Select a driver from the list of already installed drivers» (see screenshot below).
Where to look for drivers. Catalog selection
Then just point to the old (different) driver and try using it. Very often, this solution helped me, because old drivers sometimes turn out to be better than new ones!
List of drivers
5. Windows OS update: 7 ->10.
By installing, say, Windwows 10 instead of Windows 7, you can get rid of problems with drivers for function buttons (especially if you can't find them) . The fact is that the new Windows OS has built-in standard drivers for the operation of function keys.
For example, the screenshot below shows how you can adjust the brightness.
However, I should note that these "built-in" drivers may be less functional than your "native" ones ( for example, some unique features may not be available, for example, auto-adjustment of contrast depending on ambient lighting).
By the way, you can read more about the choice of Windows OS in this note: (despite the fact that the article is already a bit old, it has good ideas :)).
