And now you can easily navigate and customize your laptop's hardware functions like display settings, volume, battery and power status, wireless connectivity and more.

Windows will then automatically adjust the screen brightness according to your settings. To do so, open Control Panel and navigate to Power Options, select Change plan settings.
7. Use keyboard shortcutsMost laptops are equipped with keyboards with function buttons F1-F12. Those are shortcuts to help quickly perform some operations, including increasing and decreasing screen brightness. All you need to do is find and press the right combination of keys. Look for an icon that corresponds to the brightness – usually a sun-shaped icon with a plus "+" and a minus sign "-", or something similar.
