Basics
Here are some basic points about keeping your computer functioning properly:
• Keep your computer in a clean, dry environment. Make sure it rests on a flat, steady surface.
• Do not place items on top of the monitor or cover any of the vents in the monitor or computer. 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 switches or other controls wet. Moisture can damage these parts and cause an
electrical hazard.
• Always disconnect a power cord by grasping the plug, but not 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 power switches 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.
Keyboard
To clean your computer keyboard, do the following:
1. Apply some isopropyl rubbing alcohol to a soft, dust-free cloth.
2. Wipe each keytop surface with the cloth. Wipe the keys one by one; if you wipe several keys at a time,
the cloth may hook onto an adjacent key and possibly damage it. Make sure that no liquid drips onto
or between the keys.
