24 User Guide
If you set a power-on password, the keyboard is locked when you turn on the
computer. You must type the correct password before the keyboard will unlock.
Use the Configuration/Setup Utility program to set a power-on password. For
more information, see “Using passwords” on page 29.
You can also use the password and screen-saver features built into the Windows
operating system to assign a password that locks the keyboard and mouse after a
predefined period of inactivity. To use these features, refer to the operating system
publication that comes with your computer.
Taking care of your computer
This section provides guidelines for the proper handling and care of your
computer.
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,
sturdy surface.
• Do not place items on top of the monitor or cover any of the vents in the
monitor or computer. These vents provide air flow 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 unusable.
• Do not get the power buttons or other controls wet. Moisture can damage
these parts and cause an electrical hazard.
• Always disconnect a power cord by grasping the plug, not the cord.
Cleaning your computer and keyboard
It is a good practice to clean your computer periodically to protect the surfaces
and ensure trouble-free operation.
Attention:
Be sure to turn off the computer before cleaning.
Use only mild cleaning solutions and a damp cloth to clean the painted surfaces of
the computer.
Monitor and screen
Do not use abrasive cleaners when cleaning the surface of the monitor screen. The
screen surface is easily scratched, so avoid touching it with pens, pencil points,
and erasers.
