PREVENTIVE MAINTENANCE

                                            Maintenance is divided into two types

Active Preventive Maintenance: This type of maintenance involves cleaning the system and its components, the frequency with which it must implement this type of maintenance depends on the computer environment and quality of components. If the PC is in an extremely dirty should be cleaned on average every three months

Preventive maintenance liabilities:

This type of maintenance is the care system in its external environment, basically includes the physical conditions of operation of the electrical system and prevention. It includes physical factors such as l room temperature, the thermal power stress, pollution, dust, cigarette smoke and issues for possible shock and vibration. Concerning the electrical load factors as electrostatic, the overhead line and in some environments by radio frequency interference.

  GETTING STARTED

When you open your computer to directly manipulate the circuits, electrostatic discharge upon them if they can damage it permanently. For such manipulations must download continuously on the computer chassis (on the shield of the power supply for example) or use an antistatic wrist strap.

Remove the top cabinet                                                                                                


• Identify the main components   

• Make a small diagram of the arrangement of cards in the slots, and wires jumpered drives and hard disk. Note that these have one side colored red This signal indicates that the terminal is number 1.   

                                                                                        

• Remove the video card slots and other cards.

• Disconnect the power cords and cables from the drives, and remove the cabinet

  Unscrewing as necessary.

• Remove the microprocessor, battery and memory modules.

                                                           

Remove the storage units.Cleaning the systemThe powder is stored on components may bring several problems. One is that dust acts as insulation preventing proper cooling system, overheating will shorten the life of components. Another is that the powder contains conductive elements that can cause short circuits the system. Dust can also corrode the electrical contacts causing inappropriate behavior. Here lies the dust of cigarette contains chemicals that can conduct electricity and cause corrosion to parts of the computer. Therefore it is recommended to avoid smoking near your computer.

Software techniques for maintainingAny hardware failure that occurs in the computer equipment is feasible solution, butIncidence of failure is higher in devices that contain electronic circuits as well as mechanical parts, such as hard disks. If the hard drive were to fail the work of days, weeks or months may be lost. The only way to prevent such disasters is the backup information.

How often should be given Preventive Maintenance Team?

It is recommended that you give each computer equipment on average four times a year, but must take into account the site where it is installed since it could require up to one or two more times.
