What F keys to be primary instand of secondary with use of fn key

It would be helpful to include more information such as the device and model number.
I will assume this is a laptop. Usually there is a key 'Fn' which stands for Function. Press this key and at the same time (immediately after) press the key that turns on the keyboard lights. Laptops often have keys with dual functions. The secondary function will be printed in a different color ink than normal. This us usually blue or red but can be any color. Holding the 'Fn' key while pressing one of these will access its secondary function such as volume control, sleep mode, keyboard lights, numbers, screen brightness, and so on.

Function keys on many laptops are used as the secondary set and the individual functions of the keys have been shifted to the primary functions. Thus, if you press F1 and things are normal, you would get some kind of "help" But if, as in many laptops, the functions of those "F" keys has been reversed you might get an Internet key, a brightness key, some kind of CD opening key, or whatever the manufacture decided. F2, as another instance, is used to trigger "edit" of the current item....but in many laptops pressing F2 just turns off your wireless signal or dims the screen slightly. In those cases the way to access the expected Fkey functions is to hole the Fn key down (at the bottom left of the keyboard) then press the desired F key. Personally I find it nuts to have reversed an PC age old way but I'm not in charge of keeping people happy so it's not happening.

Hope that helps.

Hold function key and the look at the f keys. Find the f key which has a sun and and arrow pointing upwards. Press it while holding fn key.

Try to switch on the Scroll lock key and see if that will work as an alternative for the Fn key

You can switch to anexternal monitor or data projector by two methods.1. Connect the externalmonitor to the laptop's video port, power up the external monitor first and thelaptop. The video information will automatically switch to the externalmonitor.2. If you power up thelaptop first then you can switch the video output to the external monitor bypressing the Fn key and one of the Function keys, depending upon your make andmodel laptop. You can also toggle between the external monitor or both LCDscreen plus the external monitor or back to LCD screen only by pressing the Fnkey plus one of the function key. Here is a list of keycombinations for some of the laptops :-IBM ThinkPad = Fn + F7HP and Compaq = Fn + F4Toshiba = Fn + F5Dell = Fn + F8

I am unable to find a photo of your laptop's keyboard, so I cannot be certain which function key will enable your wireless adapter.

However, most laptops are very similar, so this solution should work for your problem.

1) Locate the secondary function key (probably labeled "FN") on your keyboard.
2) Locate the key which controls your wireless adapter as a secondary function. It will have the following image on the key: http://cdnsupport.gateway.com/s/Mobile/2007/Phantom/WirelessIcon.gif
3) While holding the FN key, press the wireless key
4) Your wireless adapter is now enabled. If you are still having wireless issues, the problem was not that the hardware wireless adapter was disabled.

The fn key is the function key. I am sure that helps a ton. The fn key works like a shift key, changing the buttons marked fn, like volume, screen brightness, etc. The use is that you press and hold the function key, and press teh function button and then release both.
Common uses are to turn off the mousepad, while typing, and to set screen brightness while under battery....

When your laptop boots up, Windows treats the second monitor (your TV) as a mirror of the primary monitor (your laptop screen). When Windows loads up and finishes initializing the more advanced features, it goes back to it's default setting of a single primary screen, and the secondary screen is in standby, waiting for you to do something with it. The fastest way to get the TV working would be to find the Function key on your keyboard (normally a purple-ish blue key labeled Fn) and the monitor switch key. The video switch key is normally in the Function key row (F1, F2, F3, etc...) and has the picture of a rectangle or TV-looking shape. Hold the Fn key down and then press the video-switch key once and see what happens. Lenovo laptops normally bring up a little on-screen program that allows you to pick which configuration you want. Good luck!

The Fn button is like a 'shift' key. Just as you would press <Shift> and a letter to get a capitalized letter, you press <Fn> and a function key at the same time ( <Fn><F1> or <Fn><F2> and so on) to use the secondary function for that key. For example, on one of my laptops, the <F2> key has an icon for 'wireless' (looks like an antenna). If I simply press <F2>, I will activate the function for <F2>, but if I press <Fn> and <F2> at the same time, I will turn on my wiress adapter.

<Fn> all by itself does nothing.

Hope this helps.

You have primary keys and secondary one. The secondary can be used by holding at the same time shift and the key you want to execute or the by holding fn key and pressing the one you want to press.

Also fn key sometimes is disabled in bios.
