  • Disconnect and reconnect your keyboard if it is external. Make sure that the connector is completely inserted into the port. (USB plugs fit into ports one way only, and won't allow you to make a connection if you try to connect them in upside-down.) Test the keyboard again.
  • Connect your keyboard to a different USB port.
  • Try a different keyboard on your computer if possible
If same problem occur even though the keyboard is connected in a different computer, then you need to contact a local repair tech and have it repaired.

Thank you!

Hi,
Try clicking the NumLock (or NumLck) button located above those numbers. Click it once and a light will come on. Then you can use the number keys.

No numlock key on MX5500 logitech


The ten-key keypad is used for the calculator too. The button to swith between these modes is just aboc=ve the key and has a picture of a calculator. To use directional arrow keys, this keyboard comes with it's own separate arrow keys located under the delete button. They felt no need for directional function, number input function, and calculator function.

What are the names of kyboard and its keys ?


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.
