Turning Off Your Computer
Before Working Inside Your Computer

Getting Started

This section provides procedures for removing and installing the components in your computer. Unless otherwise noted, each
procedure assumes that the following conditions exist:

You have performed the steps in "Turning Off Your Computer" and "Before Working Inside Your Computer."
You have read the safety information in your Dell™ Product Information Guide.
A component can be replaced by performing the removal procedure in reverse order.

Recommended Tools

The procedures in this document may require the following tools:

Small flat-blade screwdriver
Long Phillips screwdriver
Flash BIOS update program floppy disk or CD

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.

1. Shut down the operating system:
a. Save and close any open files, exit any open programs, click the Start button, and then click Turn Off

Computer.

b. In the Turn off computer window, click Turn off.

The computer turns off after the operating system shutdown process finishes.

2. Ensure that the computer and any attached devices are turned off. If your computer and attached devices did not

automatically turn off when you shut down your operating system, press and hold the power button for 4 seconds.

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 port or device.

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.

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

opening the cover.

4. Remove the computer cover

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.

You can increase your computer memory by installing memory modules on the system board.
Your computer supports DDR2 memory. For additional information on the type of memory supported by your computer, see

your Owner's Manual.

DDR2 Memory Overview

DDR2 memory modules should be installed in pairs of matched memory size, speed, and technology. If the DDR2 memory
modules are not installed in matched pairs, the computer will continue to operate, but with a slight reduction in performance.
See the label on the module to determine the module's capacity.

NOTE: Always install DDR2 memory modules in the order indicated on the system board.

The recommended memory configurations are:

A pair of matched memory modules installed in DIMM connectors 1 and 2

or

A pair of matched memory modules installed in DIMM connectors 1 and 2 and another matched pair installed in

NOTICE: Do not install ECC or buffered memory modules. Only unbuffered, non-ECC memory is supported.

NOTE: If you install DDR2 667-MHz memory, the speed is reduced to 533 MHz.

If you install mixed pairs of DDR2 400-MHz (PC2-3200) and DDR2 533-MHz (PC2-4300) memory, the modules function
at the slowest speed installed.

Be sure to install a single memory module in DIMM connector 1, the connector closest to the processor, before you
install modules in the other connectors.

DIMM connectors 3 and 4

NOTE: Memory purchased from Dell is covered under your computer warranty.

NOTICE: If you remove your original memory modules from the computer during a memory upgrade, keep them

separate from any new modules that you may have, even if you purchased the new modules from Dell. If possible, do
not pair an original memory module with a new memory module. Otherwise, your computer may not start properly.

You should install your original memory modules in pairs either in DIMM connectors 1 and 2 or DIMM connectors 3 and

4.

Addressing Memory With 4-GB Configurations

Your computer supports a maximum of 4 GB of memory when you use four 1-GB DIMMs. Current operating systems, such as
Microsoft® Windows® XP, can use a maximum of 4 GB of address space; however, the amount of memory available to the
operating system is less than 4 GB. Certain components within the computer require address space in the 4-GB range. Any
address space reserved for these components cannot be used by computer memory.

Removing Memory

CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the

Product Information Guide.

NOTICE: To prevent static damage to components inside your computer, discharge static electricity from your body

before you touch any of your computer's electronic components. You can do so by touching an unpainted metal surface
on the computer chassis.

1. Follow the procedures in "Before You Begin."

2. Remove the computer cover.

3. Press out the securing clip at each end of the memory module connector.

4. Grasp the module and pull up.

If the module is difficult to remove, gently ease the module back and forth to remove it from the connector.
