Keyboard Not Working

If the keyboard is not functioning at all, make sure that it is connected correctly to the computer. Check all the keyboard's plugs to make sure that there are no loose connections. Connect the keyboard to your computer by using a different USB port.

Note Bypass any port replicator, USB hub, KVM switch, or similar component, and connect the keyboard directly to the USB port on the computer. If this resolves the problem, confirm that it is this additional connection device that is the source of the problem. Contact the manufacturer to see if they can provide a solution to allow you to use their device.

If an adapter (PS/2 to USB or PS/2 to AT) is being used, verify that it is the adapter that was included with the keyboard or that the keyboard supports adapting to a different port. For example, the Internet Keyboard does not adapt to a USB port, and a PS/2 to USB adapter will not work. It does not include an adapter.

To connect or to disconnect the keyboard to a PS/2 port, follow these steps:

1. Shut down the computer.
2. Plug your device into the correct port. Make sure that the plug is pushed securely into the connector on the computer.
3. Restart the computer. Microsoft Windows detects the change, and then installs the drivers on the new port automatically.

If the issue continues to occur, try connecting the keyboard to a different computer. If the keyboard functions correctly on a different computer, the port to which the keyboard was connected on the original computer may be damaged. If this is the case, contact your computer manufacturer to inquire about how to repair or replace the damaged port.

If the keyboard does not function correctly on another computer, the keyboard may be defective. If this is the case, and the warranty on the keyboard is still valid, you can exchange the defective keyboard for a new keyboard. For information about how to contact Microsoft Supplemental Parts, see the "References" section.

If the keyboard works on another computer, go to Step 2.

4. Double-click Keyboard, right-click the keyboard that you use, and then click Uninstall.
   
   Note If your device is not listed, this means that the device was removed automatically when you disconnected the device. Go to the next step.
5. Restart the computer.
   1. First, turn on the device, if you have to, and then plug the device into the computer. Your computer detects the device and then reinstalls the drivers for the device.
