Occasionally, you may find your laptop's monitor is too dim for your liking. A normal desktop computer's monitor has an on-board menu system that lets you adjust the brightness and picture control settings as you please. A laptop monitor has no such controls. You can adjust the brightness of your laptop monitor using your laptop's keyboard.
Press and hold the ""FN"" key on your laptop's keyboard. This is the ""Function"" key, which operates much the same way that the ""Shift"" key does: It allows keyboard buttons to be used for multiple purposes. It's located in the lower left corner of most laptop keyboards, next to the ""Windows,"" ""CTRL"" and ""ALT"" keys.
Look at the top row of keys on your keyboard for a key with a tiny triangle pointing upwards and the symbol of a sun on it. This is the ""Increase Brightness"" key. With the ""FN"" key held down, press the ""Increase Brightness"" key. On most laptop keyboards this is the ""F7"" key, but it varies depending on the model.
Continue to hold down the ""FN"" and ""Increase Brightness"" key until your dim laptop monitor has reached the level of brightness you require. A laptop monitor can only get so bright. It will stop at its highest setting.
Release the ""FN"" and ""Increase Brightness"" keys. You have now fixed your dim laptop monitor.
