Connecting the Keyboard
Now that you have found the correct port for the keyboard, you can think about plugging it into the computer. I suggest separate steps for connecting the keyboard depending on whether you have USB or PS/2 ports to use.
Connecting a USB port can be done when your computer is already on. However, if you are detaching an old PS/2 keyboard, turn off the PC before doing so.
You cannot plug a USB connector incorrectly, because they only plug into a port in a specific orientation. Never jam the connector into the port. Should the connector not slide easily into the port, turn the connector until it fits into place easily. A USB connector will fit into the USB port in a straight direction.
It might be necessary for Windows to install a generic keyboard driver. This is just an application that allows Windows to talk to the new device, so don’t panic if it takes a few minutes before the keyboard will work. Should the keyboard you are connecting have any special keyboard capabilities, such as multimedia buttons for manipulating the sound or flipping through music, the associated software for these applications will have to be installed if you want to use them.
The actual process of installing differs from one manufacturer to another, so make sure to read the instruction booklet that comes with your keyboard. Usually you can just put the CD in the CD-ROM drive and follow the Install prompts that appear to do the job. You will need to follow the steps included on the CD and supply any data they ask for.
When connecting a PS/2 keyboard, always turn off the PC before detaching any connectors or attempting to attach a new keyboard. Once again, PS/2 connectors will only fit in the hole one way, so if it doesn’t fit easily in the slot just rotate the connector until it does.
After attaching your keyboard, flip the switch and the PS/2 keyboard should respond, just remember that PS/2 keyboards also require you to reload the software provided with any advanced features to get them to work.
