Keyboard could need replacing. Try connecting a USB external keyboard and see if it works. If it works okay, you need to have the laptop keyboard connections checked. Replace the keyboard if connections appear to be okay.

If the keyboard has a round purple connector, power down the computer then unplug and then plug in the keyboard. Power on the computer. If it works your done if it doesn't replace the keyboard. If this is a USB keyboard, with the computer on, unplug and plug in the keyboard if it works great, if it still isn't working replace the keyboard. NOTE if this is a multi functional keyboard (special keys at the top) make sure you install the driver and any software associated with the keyboard.

Hi,

Keyboard Is Dirty:

Keyboards should be cleaned with "spray-n-wipe" cleaner and a cloth or tissue on a monthly basis. Ensure that computer is not powered up while cleaning the keyboard. Compressed air can also be used to clean between the keyboard keys. Another tip: clean the keys with a cotton swab dipped in alcohol.

"Keyboard Not Found" Message:

Your keyboard is not plugged into the computer securely. Unplug it and plug it back in and the problem should go away. If this doesn't work, follow procedure: "Computer isn't taking inputs from keyboard" (below).

Key Is Stuck:

1. If a key does not work or is stuck in the down position, you may try to remove it with a CPU "chip puller" tool. These simple "L" shaped tools are great at pulling out keys. Once you've pulled out the stuck key, you can try to stretch the spring to "reanimate" its action.

Computer Isn't Taking Inputs From Keyboard

1. Is keyboard connected to computer? Ensure that the keyboard is plugged into the keyboard jack and not into the mouse jack. If the keyboard was unplugged, plug it back in and reboot the computer.

2. If the keyboard still doesn't work on boot-up, power down the computer and try to borrow a friend's known-good keyboard for troubleshooting. Plug the new keyboard up and boot up the computer. If the new keyboard works, the old keyboard is bad and needs to be replaced.

3. If the known-good keyboard doesn't work, check your BIOS to make sure it sees the keyboard. It should say, "installed." If the BIOS recognizes the keyboard, then you probably have a bad keyboard port.

I Plugged Keyboard Into Mouse Port

1. Many mice and keyboards today use a PS/2 connector
. If you plugged your keyboard into the mouse port (or viceversa), follow steps 2 and 3.

2. Shut down the computer and plug the keyboard into the keyboard port. The keyboard port is usually marked with a "keyboard" symbol. Plug the mouse into the mouse port (usually marked with a mouse symbol).

3. Reboot the computer; the keyboard should work now. If keyboard doesn't work, check your BIOS to make sure the BIOS recognizes the keyboard. You should see the words, "installed" or "enabled" under the keyboard.

4. If the BIOS recognizes the keyboard but it still doesn't work, you may have a bad keyboard port.

I Spilled a drink on my keyboard!

1. If you spill any liquid in the keyboard, turn it upside down ASAP. Drain all the water out of the keyboard, shaking it if necessary. If you've spilled water into the keyboard, just let it dry. You may use a hair dryer to dry out area under the keys (remember, too much heat and you could damage the electrical components).

2. If you've spilled a soda into the keyboard, completely rinse it in warm water. No soap please! You may use a hair dryer at this point or just let it dry for 2 days. Ensure the keyboard is perfectly DRY before you attempt to use it again. Don't plug a wet keyboard into electrical equipment. Think safety.

5. If the keyboard still doesn't work, replace the keyboard.

Try with a known good keyboard

If you get 'Keyboard Failure' message it can have two reasons.
1) The keyboard is not working properly. You will have to replace it.
2) If your keyboard has a PS/2 jack, the PS/2 keyboard port of your computer is not working. Buy an USB keyboard.
You can take your computer to the store and check which type of new keyboard (PS/2 or USB) works with your computer, before paying for it.

there is a problem on your keyboard hub ,, or the CPU hub,, check the hub, try it to another keyboard, if it wil work therefore your keyboard has defect

Did you install the CD software program for the Keyboard?
The Keyboard should have been plugged in before you started your computer. Then you should have installed the CD program.

Also after installation if it doesn't work try the following:
Normal 0 Press the Receiver button (and the lights will start flashing.
Then if the Keyboard isn't working, press the small RESET/CONNECT button on the back of the board to connect the keyboard to the receiver.

yeah.. maybe you have a defective keyboard.. better look at your warranty now..
