Maintenance and Troubleshooting

You can prevent many problems with your computer by daily
preventive maintenance steps. Much of preventive maintenance is
simple daily housekeeping:
1. Keep the unit free of dust.
2. Turn OFF your computer before connecting or disconnecting the
AC power or any peripheral devices to your computer.
3. Keep food and drinks away from the computer.
4. Don't smoke in the computer area.
5. Cover the computer and any peripherals when not in use.
6. Put your diskettes away when not in use. Place them in protective
envelopes and store in a closed container.
7. Check to see if any magnetized hardware is in the computer
environment. Remember that magnetized objects might damage
the diskettes and can affect the computer's memory. Even
jewelry can have magnetic properties, so be careful.
8. Keep your computer environment as static free as possible.
9. Keep the air circulation vents uncovered (refer to Figure 2-13).
10. Remove dust that may get into the computer and affect its
performance by cleaning the unit periodically. Clean the display
and the cabinets (refer to Figure 2-14).
