So you won't need to buy a supercomputer to get this tool. This tool can be very useful if you play games and have a dedicated video card. As this is what sends the information to the monitor.

Why is the brightness of my computer automatically adjusted?

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

How does auto brightness affect my computer's battery?

Auto Brightness is a feature that detects available light in the computer's environment and adjusts the brightness intensity of the screen, so battery life would be more or less affected at depending on whether the system is using that optimal screen brightness or not

That's why the most affordable for your laptop's battery life is the manual brightness adjustment and many times the automatic brightness change is annoying for many users, so if what you want is balance, your best bet is to 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. Also not all versions of Windows 10 are compatible with it. And while it may be a boon to many, there are users who decide to delete this option.

With Intel graphics settings

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

They just need to open the Intel Graphics Control Panel and click Graphics Options in the desktop menu which is located on the screen, so in the settings you can adjust the brightness of the screen to your liking.

From Windows services

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

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

This is the option that interests us, we just have to deselect it to disable automatic or intelligent brightness. Note that in doing so, you will have to manually adjust the brightness and it will not come more modified according to the lighting that the environment has.

In the power supply options in the equipment

A slightly more professional way to get rid of the smart brightness option is through the power section of the device. To access it not you have to do is notice that on the taskbar there is a battery icon.

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

Once in this window we have to look at which plan we have active, whether it is 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 that a window will open and we will have to look down, for go to advanced configuration.

This will load a small window in which there will be many options, but the one we are interested in is the one on the screen. On one side of the name there will be a plus symbol '+' on which we will have to press. So we need to turn off the smart brightness option by clicking on it and selecting turn off.

How to reactivate the automatic brightness?

Brightness in a computer is vital, since with it we can correctly display what we intend to show 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 possibility to manually adjust the brightness. In general, it is not recommended to set it to more than 80% at night, as this can adversely affect our vision. In the afternoon if we want to reduce the brightness we can do it via the keyboard.

Furthermore, it should be noted that we can reactivate the automatic brightness at any time, via either of the two methods mentioned above. This is in case we don't want to manually change the brightness.
