CHAPTER 5: Maintaining Your Computer
58
Cleaning the exterior
• Always turn off your computer and other peripheral
devices before cleaning any components.
• Use a damp, lint-free cloth to clean your computer and
other parts of your system. Do not use household
abrasive or solvent cleaners because they can damage
the finish on components.
• Your computer is cooled by air circulated through the
vents on the case, so keep the vents free of dust. With
your computer turned off and unplugged, brush the
dust away from the vents with a damp cloth. Be careful
not to drip any water into the vents.
Cleaning the keyboard
You should occasionally clean the keyboard to remove dust
and lint trapped under the keys.
To clean the keyboard:
1 Use an aerosol can of air with a narrow, straw-like
extension to remove dust and lint trapped under the
keys.
2 If you spill liquid on the keyboard, turn off your
computer and turn the keyboard upside down. Let the
liquid drain, then let the keyboard dry before trying to
use it again. If the keyboard does not work after it dries,
you may need to replace it.
Cleaning the monitor
To clean the screen:
• To clean the screen, use a soft cloth and water to clean
the screen. Dampen the cloth (never apply liquid
directly to the screen), then wipe the screen with the
cloth.
Warning
When you shut down your computer, the power turns off, but some
electrical current still flows through it. To avoid possible injury from electrical
shock, unplug the power cord, modem cable, and network cable from the wall
outlets.
Caution
A flat-panel display is made of specially coated glass and can be
scratched or damaged by abrasive or ammonia-based glass cleaners.
