Perform the following procedures in the order presented. Initial User Contact Ask the user to describe the problem and the conditions under which it occurs. Then perform the following steps: 1. Have the user back up the data on the hard drive, if possible. Refer the user to the documentation provided with the operating system or application software for information about backing up data. 2. Have the user duplicate the problem. If the user cannot duplicate the problem, proceed to "External Visual Inspection." 3. Observe the user's actions for errors such as typing an incorrect key combination or entering a command incorrectly. If the problem is a result of user error, instruct the user in the proper procedure. If it is not, proceed to "External Visual Inspection." External Visual Inspection 1. Inspect the status indicators for indications of component malfunction. 2. Turn off the system and all attached peripherals. 3. Verify that all power cables are properly connected to the system, peripherals, and their power sources. 4. Ensure that cables are properly connected to devices. 5. If a monitor is used, inspect the monitor controls for obvious damage or improper settings. For proper settings of the monitor controls, see the monitor documentation. 6. If a keyboard is used, inspect the keyboard to ensure that keys are not sticking. If keys are sticking, replace the keyboard. 7. Inspect the system and peripherals for signs of physical damage. If a peripheral is damaged, see the peripheral documentation. If the system is damaged, see "Internal Visual Inspection." Observing the Boot Routine 1.
