Mouse and keyboard problems

Action:

  1. Be sure no loose connections exist. If a KVM switching device is in use, be sure the server is properly connected to the switch.
  2. If a KVM switching device is in use, be sure all cables and connectors are the proper length and are supported by the switch. Refer to the switch documentation.
  3. Be sure the current drivers for the operating system are installed.
  4. Be sure the device driver is not corrupted by replacing the driver.
  5. Restart the system and check whether the input device functions correctly after the server restarts.
  6. Replace the device with a known working equivalent device (another similar mouse or keyboard).
  7. 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.
  8. Be sure the keyboard or mouse is clean.
