Intermittent problems Symptom FRU/action A problem occurs only occasionally and is difficult to detect. 1. Verify that: v All cables and cords are connected securely to the rear of the computer and attached options. v When the computer is turned on, air is flowing from the rear of the computer at the fan grill. If there is no airflow, the fan is not working. This causes the computer to overheat and shut down. v Ensure that the SCSI bus and devices are configured correctly and that the last external device in each SCSI chain is terminated correctly. 2. Check t he system error log. Note: See "System" on page 162 to determine which components should be replaced by a field service technician. Keyboard, mouse, or pointing-device problems Symptom FRU/action All or some keys on the keyboard do not work. 1. Verify that: v The keyboard cable is securely connected to the system, and the keyboard and mouse cables are not reversed. v Both the computer and the monitor are turned on. 2. Keyboard. 3. System board. The mouse or pointing device does not work. 1. Verify that: v The mouse or pointing-device cable is securely connected, and that the keyboard and mouse cables are not reversed. v The mouse device drivers are installed correctly. v Both the computer and the monitor are turned on. 2. Mouse or pointing device. 3. System board. Chapter 6. Symptom-to-FRU index 141
