This chapter introduces preventive maintenance and the troubleshooting process. Preventive maintenance is
a regular and systematic inspection, cleaning, and
replacement of worn parts, materials, and systems. Preventive maintenance helps to prevent failure of parts, materials, and systems by ensuring that they are in good working condition. Troubleshooting is a systematic approach to locating the cause of a fault in a computer system. With fewer faults, there is less troubleshooting to do, thus saving an organization time and money.
Troubleshooting is a learned skill. Not all troubleshooting processes are the same, and technicians tend to refine their own troubleshooting skills based on knowledge and personal experience. Use the guidelines in this chapter as a starting point to help develop your troubleshooting skills. Although each situation is different, the process described in this chapter will help you to determine your course of action when you are trying to solve a technical problem for a customer.
