Laptop Fn Keys

On a laptop, there are a few keys that have a blue icon on them. These are function keys. They work when you hold down the blue “Fn” key, which is normally next to the Ctrl key.

There are tons of Fn keys. Not all will have the same icons on them. If you want to know what yours do exactly, there should be an easy to read table in your manual. If you don’t have the manual or can’t find it, check the manufacturer’s website.

Standard Fn Keys

There are volume and mute keys . Look for a speaker. One will be crossed through or X’ed out, that’s mute. Volume up will have a lot of sound waves coming out. Volume down will have small sound waves.

Also, there are two brightness keys. These look like a small computer screen with an icon in the middle. To brighten the screen, hold down Fn and press the one with the larger icon. Use the smaller icon to make it darker.

Another key will control the monitor. It should have two screens on it with a slash between. This will flip back and forth between the laptop screen and the monitor.

There’s usually a Number Lock. Sometimes, you’ll get a Scroll Lock or System Request, even though neither of those keys is really used today.

Bonus Fn Keys

There are a few keys that aren’t on all laptops. One is the wifi key. This will look like an antenna with waves coming off either side. It turns the wifi on and off.

You may have a bluetooth key. It will have that trademark bluetooth icon. You can guess what that one does.

Another key is the sleep key. The icon varies greatly. It may be some Z’s on it, but it will definitely remind you of sleep.
