Safety Instructions

Use the following safety guidelines to help protect yourself and your
computer. For comfort and efficiency, observe the ergonomic guidelines in
“Sitting Comfortably at Your Computer” in the Tell Me How help file.

When Using Your Computer

CAUTION: Do not operate your portable computer for an extended

period of time w ith the b ase rest ing direct ly on your body. With
extended operation, heat can potentially build up in the base.
Allowing sustained contact with the skin cou ld cause d iscomfort
or, eventually, a burn.

• Do not attempt to service the computer yourself. Always follow

installation instructions closely.

• Do not carry a battery in your pocket, purse, or other container where

metal objects (such as car keys) could short-circuit the battery
terminals. The resulting excessive current flow can cause extremely
high temperatures and may result in damage from burns.

• Be sure that nothing rests on your AC adapter’s power cable and that

the cable is not located where it can be tripped over or stepped on.

• Place the AC adapter in a ventilated area, such as a desk top or on the

floor, when you use it to run the computer or to charge the battery. Do
not cover the AC adapter with papers or other items that will reduce
cooling; also, do not use the AC adapter while it is inside a carrying
case.

• Do not use your computer in a wet environment, for example, near a

bath tub, sink, or swimming pool or in a wet basement.

• Do not push objects into air vents or openings of your computer.

Doing so can cause fire or electric shock by shorting out interior
components.

• Use only the AC adapter and batteries that are approved for use with

this computer as indicated in this document. Use of another type of
battery or AC adapter may risk fire or explosion.

Safety Instructions 7

• Before you connect the computer to a power source, ensure that the

voltage rating of the AC adapter matches that of the available power
source:

– 115 V/60 Hz in most of North and South America and some Far

Eastern countries such as South Korea and Taiwan
– 100 V/50 Hz in eastern Japan and 100 V/60 Hz in western Japan
– 230 V/50 Hz in most of Europe, the Middle East, and the Far East

• To help prevent electric shock, plug the AC adapter and external

device power cables into properly grounded power sources. These
cables are equipped with 3-prong plugs to help ensure proper

www.dell.com | support.dell.com

grounding. Do not use adapter plugs or remove the grounding prong
from a cable. If you must use an extension cable, use a 3-wire cable
with properly grounded plugs.

• If you use an extension cable with your AC adapter, ensure that the

total ampere rating of the products plugged in to the extension cable
does not exceed the ampere rating of the extension cable.

• To remove power from the computer, turn it off, remove the battery,

and disconnect the AC adapter from the el ectrical outlet.

• If your computer includes an integrated or optional (PC Card)

modem, the cable used with the modem should be manufactured with
a minimum wire size of 26 American wire gauge (AWG) and an FCC­compliant RJ-11 modular plug.

8 Safety Instructions

• If your computer includes an integrated or optional (PC Card)

modem, disconnect the modem cable during an electrical storm to
avoid the remote risk of electric shock from lightning via the telephone
line.

• To help avoid the potential hazard of electric shock, do not connect or

disconnect any cables or perform maintenance or reconfiguration of
this product during an electrical storm.

• PC Cards may become very warm during normal operation. Use care

when removing PC Cards after their continuous operation.

• Do not dispose of batteries in a fire. They may explode. Check with

local authorities for disposal instruc tions.

• When setting up the computer for work, place it on a level surface.

• When traveling, do not check the computer as baggage. You can put

your computer through an X-ray security machine, but never put your
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 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 drive through an X-ray security
machine, but never put the drive through a metal detector.

• When traveling, do not place the computer in overhead storage

compartments where it could slide around. Do not drop your
computer or subject it to other mechanical shocks.

• Protect your computer, battery, and hard drive from environmental

hazards such as dirt, dust, food, liquids, temperature extremes, and
overexposure to sunlight.

• When you move 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.

NOTICE: When taking the computer from low-temperature conditions into a

warmer environment or fro m high-temperature conditions into a cooler
environment, allow the computer to acclimate to room temperature before
turning on power.

• When you disconnect a cable, pull on its connector or on its strain-

relief loop, not on the cable itself. As you pull out the connector, keep
it evenly aligned to avoid bending any connector pins. Also, before you
connect a cable make sure both connectors are correctly oriented and
aligned.

• Handle components with care. Hold a component such as a memory

module by its edges, not its pins.

• When removing a memory module from the system board or

disconnecting an external device from the computer, wait 5 seconds
after turning off the computer before removing the memory module or
disconnecting the device to help avoid possible damage to the system
board.

Safety Instructions 9

• Before you clean your computer, turn it off, unplug it from its power

source, and remove the batter y.

• 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 commercial 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 display contains
grease or some other contaminant, use isopropyl alcohol instead of
commercial window cleaner.

damage the computer, see page 35. If, after following these procedures,
you confirm that your computer is not operating properly, contact Dell
(see page 57).

Protecting Against Electrostatic Discharge

To pre vent static damage, discharge static electricity from your body be fore
you touch anything inside your computer and periodically while you work
inside the computer. You can do so by touching an unpainted metal surface
on the back of the computer.

You can also take the following steps to prevent static damage:

• Do not remove items from their antistatic pac king material until you

are ready to install them in your computer . Just befor e unwrapping the
antistatic packaging, be sure to discharge static electricity from your
body.

• When transporting a sensitive component, first place it in an antistatic

container or packaging.

• If your computer gets wet, see page34 for instructions. If you drop or
