Problems With the Mouse: Windows XP Won't Detect the Mouse on Startup
- Some mice connect to your computer using a cabled connection into a round PS/2 port or rectangular USB port.
Many use wireless mice. These have no cable but connect wirelessly to a receiver that plugs into a port on your computer. - Wired USB mice can be "hot-swapped" while your computer is on. If the mouse is not detected, wait until Windows XP is fully loaded and try to unplug and re-plug the USB mouse.
If you are using a wired PS/2 mouse, this should be plugged in while the computer is off. Shut down your PC, ensure the round PS/2 plug is firmly plugged in, and restart your computer.
You can use the same procedures to connect the receiver for a wireless mouse. In addition, the receivers usually have a "Connect" button that corresponds with a "Connect" button on the mouse. The usual procedure is to press the button on the receiver, followed by the button on the mouse. Check you documentation for the exact procedure. - Often, mice require specific drivers to support additional buttons or features. Make sure you install the software in line with the manufacturer's instructions so your mouse works as intended with Windows XP.
