Troubleshooting the Mouse
Problem
System error message indicates a mouse problem
Action
1. Determine whether the system has monitors attached to both the front and rear video connectors.
The system supports only one monitor attached to either the front or rear video connector. When a monitor is
connected to the front panel, the back-panel video, and PS/2 keyboard and mouse connectors are disabled.
If two monitors are attached to the system, disconnect one monitor. If the problem is not resolved, continue to step 2.
2. Determine the type of mouse used and to which panel the mouse is connected.
If a USB mouse is connected to a USB connector on either the front or back panel, go to step 4.
If a PS/2 mouse is not connected to the front-panel PS/2 connector, go to step 4.
If a PS/2 mouse is connected to the front-panel PS/2 connector, continue to step 3.
3. Ensure that the PS/2 mouse is connected to the front panel using a keyboard/mouse cable adapter.
The front-panel PS/2 connector supports a mouse only with a keyboard/mouse cable adapter. If a PS/2 mouse is
connected to the front-panel PS/2 connector, use a keyboard/mouse cable adapter or replace the PS/2 mouse with a
USB mouse. If you do not have a keyboard/mouse cable adapter, see " Getting Help " for instructions on obtaining
technical assistance.
4. Look at the mouse and the mouse cable for any signs of damage.
5. Click each button on the mouse.
If the mouse and its cable appear to be free of physical damage, and the buttons work, go to step 7.
If the mouse or its cable are damaged, continue to step 6.
6. Swap the faulty mouse with a working mouse.
If the problem is resolved, the mouse must be replaced (see " Getting Help " for instructions on obtaining technical
assistance).
7. Run the pointing devices test in system diagnostics.
If the test completes successfully, the faulty mouse must be replaced. If the test does not complete successfully, the
controller is faulty (see " Getting Help " for instructions on obtaining technical assistance).
