Product Information Guide.

• A component can be replaced by performing the removal procedure in reverse order.

Recommended Tools

• Flash BIOS update program floppy disk, CD, USB key

Turning Off Your Computer

NOTICE: To avoid losing data, save and close any open files and exit any open programs before you turn off

your computer.

a

Save and close any open files, and exit any open programs.

b

button, and then click

Shut Down

.

c

NOTICE: To turn off your computer without shutting down the operating system is not recommended,

holding the power button for 6 seconds.

20 Before You Begin

Before Working Inside Your Computer

Use the following safety guidelines to help protect your computer from potential damage and to help

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

.

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.

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 strain-relief loop, not on the cable itself.

Some cables have a connector 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

Turn off your computer.

NOTICE: To disconnect a network cable, first unplug the cable from your computer and then unplug it from the

network wall jack.

2

Disconnect any telephone or telecommunication lines from the computer.

3

Disconnect your computer and all attached devices from their electrical outlets, and then press the

power button to ground the system board.

4

If applicable, remove the computer stand (for instructions, see the documentation that came with the

stand).

CAUTION: To guard against electrical shock, always unplug your computer from the electrical outlet before

removing the cover.

5

Remove the computer cover:

• Remove the mini tower computer cover (see "Removing the Computer Cover" on page 39).

• Remove the desktop computer cover (see "Removing the Computer Cover" on page 177).

• Remove the small form factor computer cover (see "Removing the Computer Cover" on

page 203).

NOTICE: Before touching anything inside your computer, ground yourself by touching an unpainted metal surface,

such as the metal at the back of the computer. While you work, periodically touch an unpainted metal surface to

dissipate any static electricity that could harm internal components.
