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.

CAUTION:

Before you begin any of the procedures in this section, follow the

safety instructions in the

Product Information Guide.

NOTICE:

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.

NOTICE:

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.

NOTICE:

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.

NOTICE:

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.
