Vaio PCG-K86P What are the blue symbols on my keyboard for. When I have to type I must keep pushing the blue key marked "fn", or I get numbers appearing. How can I stop this from happening.

You use teh shift key and the [FN] key to access these extra sets of characters. If it is basically a circle around a symbol then press and Hold the [FN] key while pressing the key you want. If it is the ?,,{,},:," or any of the symbols on the upper part of the number keys at the top of the keyboard just press and hold the shift key while pressing the key.

hi
just Check the function key on your key board with symbol "Fn" is it correctly turn off or not

You need to press the "Fn" and "Num" keys. Holding the "Fn" key, press the "Num" key (also printed in blue, in most cases), the release both of them.

Shift and NUM lock(top row on keyboard)

In the lower left hand corner of your Dell Keyboard -- you will see a Blue Key labeled -- "Fn". This key allows you the use of ALL of the other blue labeled keys on your keyboard. You must press the FN key and the other "blue" key at the same time for them to work.

The keys on the right side of the keyboard with the blue numbers on them are controlled by the Numlock key and Fn key. The light at the top of the keyboard near the power button, with the number "9" inside a picture of a lock, will be lit if the Numlock is enabled.
You may need to press the Fn key to type numbers even if the Numlock is turned on. There is a setting in the BIOS called Enable Keypad and if you set it to By Numlock you will not have to hold down this key to type a number.

If you are still having trouble with these keys, please see the general keyboard troubleshooting guide

You have the number keypad so all the blue letters on the keyboard will type.

Its know as a hot key

How to turn it off.
bottem of the keyboard press "FN" hold it down
Then Press Scroll With (Lock Symbol)

It should solve the problem.. every keyboard is diffrent but im sure yours is the same as the one i am useing.

You need to press the NumLock key to get the keyboard to get back to alphanumeric - it has a symbol of a lock with a number 1 on it. A LED should also go out/icon in your tool tray should disappear as well.

With my IBM Thinkpad, I had to hold Shift+ScrLk to turn off Number Lock.

Try hooking up a different monitor. If that is not an option try looking for a key in the F-keys row that has a pic. of two monitors that might even say lcd on one of them. Hold down the Fn key and push the key with the pic once. If not then push the key twice before letting off the Fn key. And so on

hi, the problem seems with the RAM, remove and clean the contacts with an rubber/easer, this should fix ur problem,let me know
