Troubleshooting and Maintenance Guide
Keeping the Computer Free of
Dust and Dirt
Keeping your computer system free of dust and dirt will
prolong its life. Dust, pet hair, and other particles can
build up, creating a blanket effect; as a result,
components can overheat, or, in the case of the
keyboard and mouse, not work as smoothly and
effectively. Check your system once a month for visible
signs of dust and debris, and clean it about once every
three months.
Cleaning the computer and monitor
1
Unplug the computer from its power source.
2
Unplug the monitor from its power source.
3
Use a clean, dry cloth to dust the computer case
and the monitor.
4
Use a clean cloth dampened with warm water to
wipe the computer case and the monitor case
clean.
Do not use water on the monitor screen.
5
Use a clean cloth to dry the computer and
monitor case.
6
Use a clean, dry cloth to clean the monitor screen,
or, for more thorough cleaning use an antistatic
screen cleaner and a clean cloth.
Cleaning vents
Air vents keep the computer and monitor cool. To
maintain efficient air flow, keep these vents clean by
using a small battery-operated vacuum cleaner.
(A battery-operated vacuum cleaner eliminates the risk
of electric shock.)
1
Run the vacuum over the vents in the computer
case and the monitor case.
2
Remove any debris that has accumulated in and
around the computer ports (for example, the
Ethernet and USB ports).
Cleaning the keyboard and mouse
When cleaning the keyboard keys, use a low setting
on the battery-powered vacuum cleaner, to avoid
removing key caps and springs.
1
Vacuum between the keys of the keyboard and
along the grooves.
2
Use a clean, dry cloth and isopropyl alcohol to
clean buildup on the keyboard keys and along its
edges.
3
Wipe the body of the mouse and the mouse cord
with cleaning wipes or a cloth and cleanser.
If you have a rollerball mouse, clean the ball and
rollers inside:
1
Turn the mouse upside down.
2
Rotate the ball-cover ring counterclockwise to
remove the ring and release the roller ball.
3
Rinse the roller ball with soap and warm water.
4
Clean the rollers inside the mouse with a cotton
swab dampened with isopropyl alcohol.
5
After the roller ball and rollers are completely dry,
replace the ball and ball-cover ring.
NOTE:
If there is sticker residue or a spill on the
computer or monitor case, use isopropyl or
rubbing alcohol and a lint-free cloth to remove it.
