Before You Begin

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

Recommended Tools

The procedures in this document may require the following tools:

Turning Off Your Computer

NOTICE: To avoid losing data, save and close all open files and exit all open programs before you turn off your computer.
  1. Save and close any open files and exit any open programs.

     
  2. Shut down the operating system:

     

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

  1. 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 at least 8-10 seconds until the computer turns off.

     

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.
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 disconnect a network cable, first unplug the cable from your computer and then unplug the cable from the network device.
  1. Disconnect all telephone or network cables from the computer.

     
  2. Disconnect your computer and all attached devices from their electrical outlets.

     
  3. 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.
  1. Open 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 static electricity, which could harm internal components.

Removing the Computer Cover

CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the Product Information Guide.
CAUTION: To guard against electrical shock, always unplug your computer from the electrical outlet before removing the cover.
  1. Follow the procedures in Before You Begin.

     
NOTICE: Ensure that sufficient space exists to support the removed cover.
NOTICE: Ensure that you are working on a level, protected surface to avoid scratching either the computer or the surface on which it is resting.
  1. Lay your computer on its side with the computer cover facing up.

     
  2. Remove the two screws securing the cover.

Memory

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 Memory.

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

 

 

Memory Installation Guidelines

If a single DIMM is installed, you must install it in connector DIMM_1.

 

 

 

1 Pair A: matched pair of memory modules in connectors DIMM_1 and DIMM_2 2 Pair B: matched pair of memory modules in connectors DIMM_3 and DIMM_4
 

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