Why is my computer’s brightness automatically adjusted?

For computers with a Windows 8 or 10 operating system there is the option to automatically adjust the brightness of the screen depending on the amount of light that exists in the room and that the ambient light sensor of the system detects, this function is called Adaptive brightness.

How does automatic brightness affect my computer’s battery?

Automatic brightness is a function that detects the available light in the environment in which the computer is located and adjusts the intensity of the brightness of the screen, so the battery life would be more or less affected depending on whether the system uses or not the optimal screen brightness .

That is why the most convenient for the battery life of your laptop is the manual brightness adjustment and many times the automatic brightness change is annoying for many users, so if what you want is balance, the best is that you keep a stable brightness on your laptop.

Ways to turn off Automatic brightness in Windows 10

As we know, adaptive brightness is a relatively new tool in computers. Besides that not all versions of Windows 10 are compatible with it. And although it can be an advantage for many, there are users who decide to eliminate this option.

With Intel Graphics settings

There is a way to adjust the brightness of your computer screen through the Intel Graphics settings, this graphics driver allows us to make adjustments with greater precision , adjust the brightness, contrast and control the gamma rays using sliders.

They just have to open the Intel Graphics control panel and click on Graphics Options in the desktop menu that is on the screen, then in the settings you can adjust the brightness of the screen as best suits you.

From Windows services

To make this configuration, you have to go to the start menu and click on the box for the system settings. You will find it on the right side of the menu, or you can also type it in the search bar. When entering the menu you must go to the system section, this is usually one of the first.

Clicking here will show you a list with all the options that you can configure the system. But in this case what matters to us are the screen settings. If we look closely, from here we can change the brightness of the monitor manually. And just below we will notice that there is an option enabled that describes how to change the brightness depending on the luminosity. 

This is the option that interests us, we just have to uncheck it to deactivate the automatic or intelligent brightness. It should be noted that by doing this, you will have to adjust the brightness manually and it will no longer be changed depending on the lighting that the environment has.

In power options in the equipment

A slightly more professional way to eliminate the smart brightness option is through the device’s power section. To access it, all you have to do is notice that on the taskbar there is an icon in the shape of a battery.

If we right-click on this icon, we will see that we get several options, but the one that we must press is the one that directs us to the configuration. Another way is to left click on the icon and click on change power plan settings. In any case, a window will open in which we can make the adjustment.

Once in this window we must look at which plan we have active, be it the balanced one or the low consumption one. This configuration is used for any power plan, we just have to click on the letters that appear to the right of the plan. After this a window will open and we must look at the bottom, to go to the advanced configuration.

This will load a small window in which there will be many options, but the one that interests us is the one on the screen. On one side of the name there will be a plus symbol ‘+’ on which we must press. Then we must deactivate the smart brightness option by clicking it and checking deactivate.

How to reactivate the automatic brightness?

The brightness in a computer is vital, since with this we can correctly visualize what is intended to be shown on the screen. For this reason, having a good configuration can help us a lot when we want to do a task. 

From the menu where we deactivate the automatic lighting we have the option to adjust the brightness manually. In general, it is not recommended to set it at more than 80% at night, since this can negatively affect our eyesight. In the afternoons if we want to reduce the brightness we can do it through the keyboard.

In addition, it should be noted that we can at any time re-activate the automatic brightness, through either of the two methods mentioned above . This in case we do not want to be changing the brightness manually.
