Chapter 3 Lesson 3 Summary

     PC CARE AND SAFETY PROCEDURES FOR USERS

    

     How to Take Care of your PC

     1. Computers need a good working temperature to work properly. They need to be placed in a cool and dry place. You can maintain good temperature with an electric fan or air conditioning.

     2. All the cables and connectors must be tied together to keep away from walk-ways to avoid accidents.

     3. Refrain from eating in front of a computer. Food bits attract insects like ants and cockroaches that can penetrate the hardware and cause computer malfunction. Spilled drink, on the other hands, might cause short circuits.

     4. Always use an AVR ( Automatic Voltage Regulator) to regulate the electricity. Too much electric voltage might cause the unit to short. Also, turn off computers during lightning as these can cause electrical surges to the computer.

     5. Do not bump or drop the computer peripherals or components as any damage may cause them to malfunction.

     6. Avoid clutter around your computer. Use soft cloth in cleaning your computer to avoid scratches.

     7. Always scan for computer viruses. Internet connection and external storage often carry viruses that could damage files and cause computer malfunctions.
