What does the FN key on a lap top do and is there one on a desktop and if so which one???

Answer 1

The FN key on a laptop is a function key. It is used to make some of the keys on the laptop do double duty. That is necessary because to keep the keyboard small a laptop may have fewer keys. On a desktop computer that is not necessary because there is always room for a bigger keyboard with more keys on your desk.

An example of a laptop key that is activated with a FN key is one that chooses the laptop's built-in screen or chooses an external monitor.

Answer 2

To make up for the lack of keys that comes with a small laptop size (as compared to the big desktop keyboards), early laptops came with a special function key, the Fn key. You used this key in combination with other keys, like the Shift key, giving those keys multiple purposes.

Most modern laptops retain the Fn key, but you use it primarily to activate special laptop functions. These functions share other keys on the keyboard, typically the Function keys. They're marked by special icons, and these icons are color coded to match the Fn key.

Sadly, you can't find a standard for these Fn keys and their functions in the laptop world. But among the many laptops out there, you can find Fn key combinations that do the following:

* Turn the laptop's internal speaker volume up.

* Turn the laptop's internal speaker volume down.

* Mute the laptop's internal speaker.

* Increase or decrease the monitor's brightness or contrast.

* Activate an external monitor for giving a presentation.

* Activate Stand By mode.

* Hibernate the laptop.

* Lock the keyboard.
