Difficulty: Moderately Easy
Step1
Determine the type of port your laptop has. Most old laptops have a round port, called a PS/2. If your laptop doesn’t have a PS/2 port, it will have a USB port; this is the type found in most new models.
Step2
Buy a mouse that is compatible with your laptop's port.
Step3
Connect your PS/2 mouse to the PS/2 port. Alternatively, connect your USB mouse to the USB port. Configure the device using the setup wizard.
Step4
Another option would be a wireless mouse. Be sure your laptop and the wireless mouse are compatible. For instance, if your laptop is Bluetooth enabled, you can easily connect a Bluetooth wireless mouse. Insert batteries into the mouse, connect the wireless receiver to your computer and install the software.
