Panasonic Toughbook CF-51 laptop blue FN key locked on


The blue Fn key which is used to make the other keys with blue functions work is locked on. To type I have to hold down the fn key and only get lowercase letters. I can not get capital letters using this method. If I don't hold down the blue Fn key I just get the limited blue functions from my keyboard.

Where is the scroll lock key on my keyboard

Hi Mark,

for scroll Lock on your laptop try the key combination hold the Fn key and press the F12 to activate scroll lock, the same can be used to undo the Scroll Lock too.

as you will see that you can also activate most other functions with the Fn Key combination when used with the keys which have the functions printed on them in the same color as the Fn Key
for example Fn+F3 keys will toggle WiFi on or off, Fn+F4 will put the computer to Sleep, Fn+Up Arrow to increase Volume and Fn+Down Arrow to Decrease Volume etc.

hope this helps
warm regard

Unlock number lock

On a laptop, the "Num Lock" key has a function slightly different than the one it performs on full-d desktop keyboards. Activating "Num Lock" on a laptop usually transforms a set of central keys, including many letters, into number keys, allowing typists used to entering numbers on a keypad to type efficiently. While on desktop keyboards "Num Lock" usually has a dedicated key, on laptops it often shares a key with another function on MacBooks, for example, it shares the "F6" key and you must hold down the "Shift" or "Fn" key to activate it.

Look for the "Num Lock" key on your laptop's keyboard. This is usually near the top of the keyboard. If the key says nothing on it except "Num Lock" if that's the only function the key performs you can just press it to activate the lock; a light will probably go on somewhere to indicate that "Num Lock" is on. If the key has multiple functions, you'll have to hold down a different key while pressing it. Hold down "Shift" and press "Num Lock" if the writing saying "Num Lock" appears above some other writing on the key, the way various symbols appear above the numbers on the keyboard's number row. Hold down "Fn" and press "Num Lock" if the writing saying "Num Lock" appears in a different color often light blue that's shared by the "Fn" key.

Jumbled keyboard numbers

Are you typing on your laptop and notice the text has become illegible? What should be letters, have become numbers or symbols. This odd behavior can probably be explained be peering a little closer at your keyboard. Those little numbers on the keys. These numbers and symbols normally become active when you hold down the function key, usually labeled as the "FN" key. The "FN" key is similar to the Shift key, activating a second function assigned to a key. It can become active seemingly on it's own because a key is locked in the on position.

Before performing numerous key combinations, try the simple thing of lightly tapping the "FN" or "Num Lock" 5 to 6 times. There may be a small particle of something logged under the key that you can loosen, move, or crush down. Do not bang the keys, just press normally. Next focus on the "Numlock" key which usually located with the "Print Screen" and "Pause" key on the top right of your keyboard. Press the "Numlock" key, then press a scrambled key to see if it's normal. Older model laptops may require you hold down at the same time, the "Ctrl-Shift-Numlock" keys. Newer models may require holding down the "Shift" key and pressing the "Numlock" key. Turn off the Function key with the following combinations. Hold down the "FN" key and hit the "Numlock", Hold down the "FN" key and hit the "Scroll" key and Hold down at the same time "Fn+F12+Num Lock"

How i can enble function key

HP laptops have the ability to lock the blue special function keys on, making numerical data entry easier on laptop models that do not have the room for dedicated numerical keypads. Because the key combination to lock the function keys is so simple, however, it is easy for those who wouldn't normally use this ability to do so accidentally. When the function keys are locked, pressing certain keys will result in numbers being typed rather than letters. Unlock the function keys to alleviate this issue.

Press the "Fn" and "Num Lk" keys on the keyboard simultaneously. The "Number Lock" indicator light should turn off, indicating that the letter keys will once again type letters when pressed. This combination should work on the majority of recent HP laptops. If it does not, try one of the alternate key combinations in this article's remaining steps. Press the "Fn" and "F11" keys simultaneously, then attempt to type a letter. If the combination does not work, continue to the next step. Press the "Fn" and "Scroll Lock" keys simultaneously, then attempt to type a letter. Continue to the next step if this does not work. Press the "Fn," "Scroll Lock" and "F11" keys simultaneously.

My dell laptop types numbers instead of letters on some keys without pressing fn key

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.

Keyboard stuck on fn

I found this on another site, and it worked on my Vostro 1510:

Try pressing shift + numlock (Scrolllock in blue) to toggle the Fn feature.

Normal numlock comes on, so press it again by itself to turn that off.
