Today we've been asked, "how do I increase the screen brightness on my laptop?"
Your laptop should have "power management" options, by default these are configured to conserve your battery life, which can make your monitor quite dim and generally cause eye strain when trying to look at your monitor. What most people don't realize is that your laptop can usually increase the brightness to a level you're more comfortable with (like that you use when you're on power). Now, these settings can be used for both "on battery" and "while connected" power settings (as both settings are separate).
First, locate your Function key (generally labeled "Fn", usually it is located in the bottom left corner of your laptop, near the shift key). Now, locate the "light" key (there is also usually a "contrast" key). When you press the "Light Up" key while holding the "Function Key" you'll notice your monitor get brighter. Likewise, if you press the "Light Down" key you'll notice the display get dimmer.
Different keyboards have different function keys, your manufacturers keys will vary, but almost all will have a light key if not many, many more...
