Safety Instructions
When Using Your Computer
As you use your computer, observe the following safety
guidelines:
• When traveling with your computer, do not check
the computer as baggage. You can put your computer
through an X-ray security machine, but never put the
computer through a metal detector. If you have the
computer checked by hand, be sure to have a charged
battery available in case you are asked to turn on the
computer.
• When traveling with the hard-disk drive removed
from the computer, wrap the drive in a nonconducting
material, such as cloth or paper. If you have the drive
checked by hand, be ready to install the drive in the
computer. You can put the hard-disk drive through an
X-ray security machine, but never put the drive
through a metal detector.
• Do not place the computer in overhead storage com-
partments where it could slide around. Do not drop
your computer or subject it to other mechanical
shocks.
• When setting up the computer for work, place it on a
level surface.
• Protect your computer, battery, and hard-disk drive
from environmental hazards such as temperature
extremes, dirt, dust, food, liquids, and overexposure
to sunlight.
• When moving your computer between environments
with very different temperature and/or humidity
ranges, condensation may form on or within the
computer. To avoid damaging the computer, allow
sufficient time for the moisture to evaporate before
using the computer. When taking the computer from
low-temperature conditions into a warmer environ-
ment or from high-temperature conditions into a
cooler environment, allow the computer to acclimate
to room temperature before using it.
• If using alternating current (AC) power, be sure
nothing rests on your adapter’s power cable and that
the cable is not located where it can be tripped over
or stepped on.
• When unplugging a power cable, grasp its plug, not
the cable itself.
• Before you clean your computer, turn it off, unplug it
from its power source, and remove the battery. Clean
your computer with a soft cloth dampened with
water rather than with liquid or aerosol cleaners.
• Clean the display with a soft, clean cloth and com-
mercial window cleaner that does not contain wax or
abrasives. Apply the cleaner to the cloth; then stroke
the cloth across the display in one direction, moving
from the top of the display to the bottom. If the dis-
play contains grease or some other contaminant, use
isopropyl alcohol instead of commercial window
cleaner.
• If your computer gets wet or is damaged, follow the
procedures described in Chapter 3, “Troubleshooting
Your Computer.” If, after following these procedures,
you confirm that your computer is not operating prop-
erly, contact Dell Computer Corporation. (See
Chapter 5, “Getting Help,” for the appropriate tele-
phone number.)
CAUTION: If your computer gets very cold,
allow it to warm gradually to room tempera-
ture before turning on the power.
