Mouse and keyboard issues
Action
- Be sure no loose connections exist by verifying the following:
- If a KVM switching device is in use, be sure the server is properly connected to the switch.
- For rack-mounted servers, check the cables to the switch box and be sure the switch is correctly set for the server.
- For tower model servers, check the cable connection from the input device to the server.
- If a KVM switching device is in use, be sure all cables and connectors are of proper length and are supported by the switch. See the switch documentation.
- Be sure the current drivers for the operating system are installed.
- Be sure the device driver is not corrupted by replacing the driver.
- Restart the system and check whether the input device functions correctly after the server restarts.
- Replace the device with a known working equivalent device (another similar mouse or keyboard):
- If the issue still occurs with the new mouse or keyboard, the connector port on the system I/O board is defective. Replace the board.
- If the issue no longer occurs, the original input device is defective. Replace the device.
- Be sure the keyboard or mouse is connected to the correct port. Determine whether the keyboard lights flash at POST or the NumLock LED illuminates. If not, change port connections.
- Be sure the keyboard or mouse is clean.
