Gateway computer laptops are equipped with special function keys on the keyboard that enable the user to increase or decrease screen brightness on the built-in LCD panel in increments. In dim lighting conditions it can be useful to brighten the screen for easier viewing, while decreasing the brightness can help in reading text on the screen in direct lighting conditions, such as using the laptop outdoors on a sunny day. The adjustment takes only a few seconds.
