Troubleshooting

Before getting started

1. Difficulty of installing computer mouse should be a 1 out of 5.
2. When connecting the PS/2 or Serial mouse, ensure the computer is off; if the mouse is a USB mouse the computer can be off or on during the installation.

Connect cables

PS/2 Mouse

1. Connect the mouse to the PS/2 port on the back of the computer. Today, although many computers are still using PS/2 mice if you're using a USB mouse skip to the next section.
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 mouse into the teal or green connection as shown in the below pictures. If your PS/2 ports are not color coded the mouse will be the connection furthest away from 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 mouse connection may be either depending on the type of case and motherboard. Look for a small symbol next to the port to identify which one is the mouse.

Serial Mouse

Connect the mouse to the serial port on the back of the computer. If the computer has serial devices currently connected to the computer and the computer has two serial ports we recommend you use the first serial connection if you encounter problems connecting the mouse. Once connected depending on your computer setup you may need to configure the mouse in CMOS setup as found in the next section.

USB Mouse

Connect the USB mouse to the USB ports on the back or front of your computer or if you are using a USB port hub, connect the mouse to to the hub.

Install Software / Drivers

Additional information about computer mouse drivers and software can be found on document CH000548.

Setup in CMOS setup

If you've connected a serial or USB mouse it may be necessary to setup the ports in CMOS setup.

If the mouse you're using is a serial mouse and it's having issues being detected verify that the serial ports or COM ports are enabled and assigned properly in CMOS.

If the mouse was a USB mouse, ensure that USB is enabled and if available, also ensure that the USB Legacy support is also enabled; this allows the mouse to work in legacy mode, for example: DOS.

Additional information about getting into CMOS setup can be found on document CH000192.
