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.
3. To remove any crumbs or dust from beneath the keys, you can use a camera blower with a brush
or cool air from a hair dryer.
Note: Avoid spraying cleaner directly onto the display or the keyboard.
Optical mouse
This section provides instructions on how to clean an optical mouse.
An optical mouse uses a light-emitting diode (LED) and an optical sensor to navigate the pointer. If the
pointer on the screen does not move smoothly with the optical mouse, you might need to clean the mouse.
