Installing a PC computer keyboard

Connect cables

Note: When connecting the PS/2 keyboard, ensure the computer is off; if the keyboard is a USB keyboard the computer can be off or on during the installation.

PS/2 Keyboard

  1. Connect the keyboard to the PS/2 port on the back of the computer.
  2. When looking at the back of the computer you'll notice two PS/2 ports next to each other. Verify you're connecting the keyboard into the purple connection as shown in the picture below. If your PS/2 ports are not color coded the keyboard will be the connection closest to the left edge of the computer (when looking at it from the back). If the connections are vertical and not horizontal as shown below the keyboard connection may be either depending on the case and motherboard. Look for a small symbol next to the port to identify what one is the keyboard.

Tip: If you are confused what PS/2 cable is what when under your desk, the PS/2 cable is often thicker than the PS/2 mouse cable.

USB Keyboard

Connect the USB keyboard to the USB ports on the back or front of your computer. If you are using a USB hub connect the keyboard to that hub.

Install software and drivers

If your keyboard has any special features such as a built on touch pad or special buttons or is wireless, for these features to work properly, the software and drivers for the keyboard must be installed after the computer keyboard has been connected to the computer.
