On most laptop keyboards, you will find shortcut keys that can quickly increase and decrease brightness. Usually, these keys are function keys (from F1 to F12) and are usually located at the top of the keyboard. If you want to adjust the screen brightness, look for the brightness symbol (usually a logo).

Since the F keys are function keys, you must hold down the Fn key on the keyboard (usually located near the lower-left corner of the keyboard) when you press them to work.
