When working on a laptop, the screen brightness adjustment function is sometimes required. Continuous operation at high brightness is tiring and has a negative effect on vision. If on a regular desktop the monitor brightness is changed by one hardware button, then on a laptop there is not always such an opportunity. You have to look for the coveted keyboard shortcut or go through the menu.
The brightness of a laptop running on a Windows operating system is changed primarily through the "computer power management" menu. Depending on the version of the Windows operating system, the coveted slider may be located in different points of the menu. It can be found through the computer control panel. The item "power management" is always dedicated to a separate tab, on which there is a choice of power management schemes.
Let's take an example of how to change the brightness of a laptop screen in Windows 10. Your path to the slider will be something like this. We open the start menu, look for the "All applications" tab in it. We go there, select the item "Service Windows". In the service item there is a button "Control Panel". From the control panel we go to the “System and Security” menu and there we find the coveted “Power Supply” tab. Now, depending on the version of Windows, you will see a window with a slider responsible for brightness.
The window might look like this:
Or like this:
In both cases, one slider with the name "Brightness" is responsible for the brightness of the screen. Now you can adjust the current brightness or change its parameters in the power scheme. This is where the mystery of automatically changing the screen brightness when running on battery lies.
Also, on some laptops, the arrows have a function for changing the brightness. If your laptop has this type of control, then the sun disk icons will be drawn on the up and down arrows. You need to press these buttons in conjunction with the Fn button.
To preserve eye health, we advise you to choose a third of the brightness of the possible screen brightness. The bright glow is not very good for the health of the eyes during prolonged use.
