Before Working Inside Your Computer

Use the following safety guidelines to help protect your computer from

potential damage and to help to ensure your own personal safety.

WARNING: Before working inside your computer, read the safety information

that shipped with your computer. For additional safety best practices

information, see the Regulatory Compliance Homepage at

www.dell.com/regulatory_compliance.

CAUTION: To avoid electrostatic discharge, ground yourself by using a wrist

grounding strap or by periodically touching an unpainted metal surface (such as

a connector on your computer).

CAUTION: Handle components and cards with care. Do not touch the components

or contacts on a card. Hold a card by its edges or by its metal mounting bracket.

Hold a component such as a processor by its edges, not by its pins.

CAUTION: Only a certified service technician should perform repairs on your

computer. Damage due to servicing that is not authorized by Dell is not covered by

your warranty.

CAUTION: When you disconnect a cable, pull on its connector or on its pull-tab,

not on the cable itself. Some cables have connectors with locking tabs; if you are

disconnecting this type of cable, press in on the locking tabs before you

disconnect the cable. As you pull connectors apart, keep them evenly aligned to

avoid bending any connector pins. Also, before you connect a cable, ensure that

both connectors are correctly oriented and aligned.

CAUTION: To avoid damaging the computer, perform the following steps before

you begin working inside the computer.

1

Ensure that the work surface is flat and clean to prevent the computer

cover from being scratched.

2

Turn off your computer (see "Turning Off Your Computer" on page 7) and

all attached devices.

CAUTION: To disconnect a network cable, first unplug the cable from your

computer and then unplug the cable from the network device.

Press and eject any installed cards from the Media Card Reader.
