Chapter 6. Preventing problems
This chapter provides information that can help you avoid common problems and keep your computer
running smoothly.
Basics
Here are some basic points about keeping your computer functioning properly:
• Keep your computer in a clean, dry environment. Ensure that the computer rests on a flat, steady surface.
• Do not cover any of the vents in the computer or monitor. These vents provide airflow to keep your
computer from overheating.
• Keep food and drinks away from all parts of your computer. Food particles and spills might make the
keyboard and mouse stick and unusable.
• Do not get the power button or other controls wet. Moisture can damage these parts and cause an
electrical hazard.
• Always disconnect a power cord by grasping the plug instead of the cord.
Cleaning your computer
It is a good practice to clean your computer periodically to protect the surfaces and ensure trouble-free
operation.
CAUTION:
Be sure to turn off the computer and monitor before cleaning the computer and monitor screen.
Computer
Use only mild cleaning solutions and a damp cloth to clean the painted surfaces of the computer.
Display screen
Dust buildup compounds problems associated with glare. Remember to clean your monitor screen
periodically.
Cleaning a flat-panel monitor surface
To clean the flexible film surface of a flat-panel computer display, wipe it gently with a soft, dry cloth, or
blow on the screen to remove grit and other loose particles. Then moisten a cloth with LCD cleaner and
wipe the screen surface.
Many computer supply stores carry the special cleaning fluids for displays. Use cleaning fluids developed for
LCD displays only. First apply the fluid to a lint-free, soft cloth, then clean the LCD display. Some computer
supply stores carry pre-moistened towelettes for LCD maintenance.
Cleaning a glass-screen surface
To clean a glass-screen surface, wipe it gently with a soft, dry cloth, or blow on the screen to remove grit and
other loose particles. Then use a soft cloth moistened with a nonabrasive liquid glass cleaner.
