Number keys above letters works but the number key pad on right is frozen

If you have a full size keyboard with a separate numeric keypad on the right. Then above that keypad is a key that says Num Lock, whilst the machine is on, press that key once and then check to see if it's working. Some Keyboards have a light that goes on when the NumLock key is pressed. Hope that explains ok ??

did you try another usb port?

When you type in you password use only the numbers that are above the key board of letters
.
Don't use the key pad of numbers
.
And make sure Caps are used if any
.
That is the one problem I run into every once and a while the web site likes me to use the numbers above the letters not the key pad of numbers
.
Why you may ask - I have no idea
.

If numbers are appearing instead of letters then -
You have press the NumLk key (number lock) and this changes the right hand keys to a number pad.
Press the NumLk key (also doubles as the ScrLk key to toggle the Number lock). it is near the F12 function key. When the NumLk has been enabled a LED light is turn on to indicate this function has been selected. Press the NumLk key again to turn off the Number Lock.

it is only for a computer keyboard hope it help from you.

A computer keyboard serves as a main operating tool for accessing and inputting data into a computer. The keyboard features many functions and keys that a user may never use, but is still essential to some users. Understanding the keyboard can improve computer knowledge and use.

QWERTY Pad

The "QWERTY" pad is main sections of letters on the keyboard. These letters are mainly used for typing and also as shortcuts in programs like Windows Movie Maker, Adobe After Effects and computer games.
Number Pads

The far right side of the keyboard features a number pad that resembles a calculator. This number pad is essential for programs like Excel, but can also be used to input numbers as a typing function. More numbers are just above the "QWERTY" keyboard that also feature symbols when the "Shift" button is used.
Arrow Keys

The right bottom of a keyboard features four directional arrow keys. These keys provide navigation through word processing documents and also serve as scrolling functions in web browsers.
F Bar

The top of a keyboard features the "F Keys," a selection of keys that extends to "F12" on most keyboards. These keys serve different functions. For example, "Alt and F4" exits out of a program. "F1" will start the typing helper in word processing programs.
Extra Keys

New keyboard feature shortcut keys at the top of the keyboard. These include shortcuts like "Power," "Sleep Mode," "Calculator," "My Computer" and "Web." Some also include media controls for movies and music.

Hi, hold down the ALT key and then type 0244 on the number pad on the right of the keyboard, then let go the ALT key. You should then get the letter: ô

If you want the upper case ô - do the same as above but use the number 0212

This should be a simple fix, look at your keyboard, you should have a function key and if you look at the number pads above the top row of letters there should be either a numerical symbol or a key pad, your keyb board is simply using several keys as an extended numerical keypad. If you look closely at the letters there are small numbers on them. To fix hold down function key and pressing the keypad button. You can also try pressing the number lock.

Al

Hold the "Fn" key down while pressing "F9" key, subtitled "Padlock" (!!) - is equivalent to NUM LOCK nomenclature used on most computers. Note - Repeating above resets number pad to ON.

If that doesn't work for you something is malfunctioning as far as I know.

If you are using windows xp,Try rebooting while holding down the f8 key.Select last known good configuration,and see if that helps.
If not,consider a re-format

There is a Fn key on the bottom left of the keyboard and a num lock key at the top right of the keyboard (depending on the model) Hold the Fn key and then press the num lock key, that should fix your problem.
