Fn where can i find the Fn key in my dell laptop

You can switch to an external monitor or data projector by two methods.
1. Connect the external monitor to the laptop's video port, power up the external monitor first and the laptop. The video information will automatically switch to the external monitor.
2. If you power up the laptop first then you can switch the video output to the external monitor by pressing the Fn key and one of the Function keys, depending upon your make and model laptop. You can also toggle between the external monitor or both LCD screen plus the external monitor or back to LCD screen only by pressing the Fn key plus one of the function key a few times.
Here is a list of key combinations for some of the laptops :-
IBM ThinkPad = Fn + F7
HP and Compaq = Fn + F4
Toshiba = Fn + F5
ASUS and Dell = Fn + F8

The Fn key (also known as the Function key) is a feature found on most laptop computers. The Fn key allows keys on a laptop computer's keyboard to serve more than one function, a clever way of increasing the utility of the keyboard when space is limited. Dell laptops make good use of the Fn key, and if you own a Dell laptop, you should be aware of where the key is and how to use it.

Open your laptop and turn it on. Then locate the Fn key. It is located on the lower left side of the keyboard, next to the Ctrl key. Press and release the Fn key. Now examine the keyboard carefully. You'll notice that many of the keys have icons or letters and numbers printed in blue upon them. These keys and functions are operated when the Fn key is enabled, as you've just done. Test it out by looking at the lower right side of the keyboard. You'll see two keys with small blue "sun" icons. These control the brightness of the screen. Press the lower one several times and you'll see the screen darken. Press the upper one. The screen brightens. Press and release the Fn key again. Now try using the brightness keys. The screen brightness will not change. You've turned off the Fn key.

HI,
If you Are writing numbers instead of letters when you press the keyboard of your laptop and you must hold down the Function key (Fn) to write normally.

This is due to the fact that the digital lock is activated. To solve this, simply press the Fn+Numlk or depending of the model, press the button or Fn + Shift +Numlk

Hope This Helps
THANK YOU

Press the FN and F2 keys together 

Press shift + numlock key. This will return the FN key to it's normal functionality, only working when you press it.
