Mouse Fails to Work
If your mouse fails to work, perform the following steps to identify and resolve the
problem:
1. Be sure the mouse is connected to the appropriate connector on the back of the
system unit.
2. Inspect the mouse connector for any broken, bent, or loose pins.
3. If the mouse cable is attached to the proper connector, turn off your computer.
Connect a mouse you know to work to your computer’s keyboard connector.
Then turn on your computer, start an application that requires you to use your
mouse and move and click the mouse.
• If the second mouse works, the problem may be with the previously con-
nected mouse.
• If the second mouse fails to work, the problem might be with the mouse or
the mouse driver installed in your computer. Contact @Xi Computer Cor-
poration technical support (see
“Technical Support” on page 81 ).
