PREVENTIVE MAINTENANCE

Preventive maintenance refers to carrying out measures to prevent problems

from occurring, in contrast to corrective maintenance, which seeks to solve an

already-existing problem. In the long run, preventive maintenance saves time

and money, protects your data, improves computer performance, and

prolongs computer life. These are accomplished by considering and planning

for the risks involved in working with computers (e.g. data loss, hardware

failure). Preventive maintenance can be classified into: 1) Mechanical

Maintenance, 2) Electrical Maintenance, and 3) Software or Hard Disk

Maintenance.

Mechanical Maintenance

General Cleaning

The benefits of cleaning your computer periodically are not limited to merely

improving its performance. Regular cleaning is also important for prolonging

your computer’s life and enhancing its performance. By removing dirt, dust

and other particles that can interfere with connections in computer circuits, the

efficiency of your computer is increased, and the chances of overheating

lowered.

Generally, your computer should be cleaned every 4-6 months. However, if

your computer is used often and operates in a dusty environment, it should be

cleaned more frequently, i.e. every 3-4 months. Other factors, including the

number of users and whether or not they own pets, also influence the

frequency of cleaning.

To clean your computer, you will need the following: 1) screwdriver, 2) can of

compressed air, 3) cleaning liquid, 4) cotton swabs, and 5) paper towel or

cotton cloth. The general cleaning procedure as outlined in the Computer

Cleaning Guide involves cleaning the keyboard, mouse, monitor, case,

interior, DVD / CD drives, hard drive, printer. Steps for cleaning a laptop are

also included. ComputerHope? also provides extensive information on

cleaning these parts of the computer, along with additional components such

as the scanner and headphones.

Choosing a Good Location for Your Computer

Ensure that the computer is placed in an area with good ventilation such that

the heat generated by the microprocessor, motherboard, and other devices is

dissipated. In addition, books and other objects should not be placed on top of

the monitor case, as this would block excess heat from escaping from the

ventilation slots. This could cause color shifting, screen flicker, and failure.

Electrical Maintenance

Surge Protection

dotParagon () provides a brief description of the electrical aspect of

maintenance, specifically surge protection, which involves safeguarding

computer components such as the monitor, hard drive, and processor from

voltage variations, i.e. spikes and surges. Spikes occur when lightning strikes

a transformer, whereas surges occur when high-powered electrical motors

are shut off, subsequently releasing extra voltage into the line. During power

outages, any unsaved ongoing work is lost. Rural areas, which are more

prone to surges, are recommended to make use of an interruptible power

supply (UPS) to avert this problem.
