New keyboard does not work
To connect or to disconnect the keyboard to a PS/2 port, follow these steps:
Shut down the computer.
Plug your device into the correct port. Make sure that the plug is pushed securely into the connector on the computer.
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.
If the keyboard works on another computer, go to Step 2.
Step 2: Download and install the latest keyboard software
Step 3: Manually reinstall the drivers
To remove and then reinstall the drivers, follow these steps:
Disconnect the device from the computer.
Turn off the power for the device, if the device has a separate power supply.
Open Device Manager. To do this, use one of the following methods:
In Windows Vista or Windows 7, click Start, type device in the Start Search box, and then click Device Manager in the Programs list. If you are prompted for an administrator password or for a confirmation, type the password, or click Allow.
In Windows XP, click Start, click Run, type devmgmt.msc, and then click OK.
Double-click Keyboard, right-click the keyboard that you use, and then click Uninstall.
If your device is not listed, this means that the device was removed automatically when you disconnected the device. Go to the next step.
Restart the computer.
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.
