How to adjust brightness on an acer laptop. Changing brightness through power settings

Hello.

A fairly common problem on laptops is the problem of screen brightness: it either does not adjust, then changes on its own, then everything is too bright, or the colors are too weak. In general, it’s just a “sore topic.”

In this article I will focus on one problem: the inability to adjust brightness. Yes, this happens, I myself periodically encounter similar questions in my work. By the way, some people neglect to adjust the monitor settings, but in vain: if the brightness is too low (or too high), the eyes begin to strain and get tired quickly.

So where to start solving the problem?

1. Brightness adjustment: several ways.

Many users, having tried one method of adjusting the brightness, come to an unambiguous conclusion - it cannot be adjusted, something has “frozen” and 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 won’t even remember that one of the methods is not working for you...

I suggest trying several options; I’ll discuss them below.

1) Function keys

On almost everyone's keyboard modern laptop There are functional buttons. They are usually located on the F1, F2, etc. keys. To use 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 appears on the screen (no control) - move on...

2) Taskbar (for Windows 8, 10)

In Windows 10, you can very quickly adjust the brightness by clicking on the power icon in the taskbar, and then left-clicking on the rectangle with brightness: adjust it optimal value(see screenshot below).

3) Via control panel

First you need to open the Control Panel at: Control Panel\All Control Panel Items\Power Options

4) Via video card driver

The easiest way to open the video card driver settings is to click right click mouse on the desktop and from context menu select graphic characteristics (in general, it all depends on the specific driver; sometimes you can go to its settings only through the Windows control panel).

In the color settings, there are usually parameters for setting: saturation, contrast, gamma, brightness, etc. Actually, we find the desired parameter and change it to suit our requirements.

2. Are the function buttons enabled?

Very common cause, due to which the functional buttons on the laptop do not work (Fn+F3, Fn+F11, etc.) - are BIOS settings. It is possible that they are simply disabled in the BIOS.

The choice of section where to enter the BIOS depends on your manufacturer. Here (within the framework of this article) it is unrealistic to give a universal recipe. For example, in HP laptops - check System section Configuration: see if the Action Keys Mode item is enabled there (if not, switch it to Enabled mode).

Action keys mode. Laptop BIOS HP.

On DELL laptops, function buttons are configured in the Advanced section: the item is called Function Key Behavior (you can set two operating modes: Function Key and Multimedia Key).

3. Lack of key drivers

It is possible that the functional buttons (including those responsible for screen brightness) do not work due to a lack of drivers.

Give a universal name for the driver in this question (which you can download and everything will work)- it is forbidden (by the way, there are some of these on the Internet, I highly recommend not using them)! Depending on the brand (manufacturer) of your laptop, the driver will be called differently, for example: in Samsung it is “ Control Center", in HP - "HP Quick Launch Buttons", in Toshiba - Hotkey utility, in ASUS - "ATK Hotkey".

4. Incorrect drivers to the video card. Installing "old" working drivers

If everything worked as it should for you before, and after Windows updates (by the way, when updating, you usually always install a different video driver)- everything started to work wrong (for example, the brightness slider moves across the screen, but the brightness does not change)- it makes sense to try to roll back the driver.

By the way, important point: You must have old drivers with which everything worked well for you.

How to do it?

1) Go to the panel Windows management and find the device manager there. You open it.

Updating the driver in Device Manager

Then select "Browse this computer for driver software."

By the way, it's possible that old driver (especially if you just updated old version Windows, rather than reinstalling it again) already on your PC. To find out, click the button at the bottom of the page: "Select a driver from the list already installed drivers" (see screenshot below).

Where to look for drivers. Directory 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 work function keys.

For example, the screenshot below shows how you can adjust the brightness.

I should note, however, that these "built-in" drivers may be less functional than your "native" ones ( for example, some unique functions may not be available, for example, auto-adjustment of contrast depending on external lighting).

What to do if the brightness does not decrease or increase

There are several reasons why this problem may occur. The most common of them:

Reason 1: Light sensor

Some expensive laptop models have a light sensor that changes brightness depending on the light level. Often this sensor makes it difficult to set the screen brightness to a comfortable level for the user. And sometimes this sensor fails.

To solve this problem, you need to disable the sensor in your laptop's settings and use one of the methods described above to set the optimal monitor brightness level.

Reason 2: Backlight system malfunction

This is true for older laptop models, where glass tubes are used as backlighting rather than LEDs. The fact is that the resource of these elements is limited and if they fail, the backlight turns off completely, but the user can see the image on the screen and think that the brightness level is set to the minimum value.

It is necessary to contact a specialized service, where professionals will replace the damaged parts, however this procedure not cheap, due to the difficult availability of spare parts.

Reason 3: viruses

It is extremely rare, but worth mentioning. Some viruses are able to control the brightness of the screen, which interferes with normal operation.

You need to scan your computer with an antivirus, or preferably several. To prevent reinfection It's best to have an antivirus with real-time protection.

It is worth recalling that some of the described methods may differ or may not work at all on your computer due to different versions installed Operating System and individual characteristics of the laptop. So if one method doesn't work on your computer, don't despair, try another. I hope you liked the article.

If, due to certain circumstances, you have to work at a laptop computer in conditions of insufficient or even poor lighting, this, firstly, introduces discomfort and inconvenience into the work process, secondly, it significantly complicates the work, and, thirdly, has an impact on negative impact on your vision.

Adjusting brightness on an Acer laptop

Method one - function keys

To adjust the screen brightness to laptop computers Acer (increase and decrease) you can use the Fn function key, which must be pressed simultaneously with the “right” and “left” arrows. Do not confuse them with the “up” and “down” arrows, which are often used to adjust the volume, although on some older models of Acer laptops, these arrows function as screen brightness controls.

Method two - adjusting power settings

The fact is that when the laptop is running on battery power, that is, offline mode, there is a process of some kind of resource saving, so at such times the brightness of the monitor has a low power. If the laptop is powered by the network, then the screen brightness is maximum. Adjust this process can be done through the Control Panel. In the "Power supply" section this menu We adjust the brightness in both modes using the slider.

Method three - through Windows Mobility Center

Method four - using third-party programs

You can also adjust the brightness using various utilities that can be downloaded on the Internet. One such program is iBrightnessTray. It does not require installation and has an automatic start function.

If none of the methods helped you, you should also try updating your video card drivers. If problems with brightness arose, on the contrary, after updating them, then it is worth returning to the earlier versions.
