This chapter 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 Safety Instructions.
You have read the safety information that shipped with your computer.
A component can be replaced or—if purchased separately—installed by performing the removal procedure in reverse

order.

Technical Specifications

For information on technical specifications of your computer, see the Quick Reference Guide that shipped with your computer
or see the Dell Support website at support.dell.com.

Recommended Tools

The procedures in this document may require the use of a small Phillips screwdriver size #2.

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. Shut down the operating system.

2. Ensure that the computer and all 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 about 4
seconds to turn them off.

Safety Instructions

Use the following safety guidelines to help protect your computer from potential damage and to help to ensure your own
personal safety.

CAUTION: 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.

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.

2. Turn off your computer (see Turning Off Your Computer

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

network device.

3. Disconnect all telephone or network cables from the computer.

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

5. Press and hold the power button while the system is unplugged to ground the system board.

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.

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 DIMM
connectors 3 and 4.

NOTE: If you install mixed pairs of PC3-8500 (DDR3 1066-MHz) and PC3-10600 (DDR3 1333-MHz) memory, the

modules function at the speed of the slowest module installed.

6. Align the notch on the bottom of the module with the tab in the connector.

1 cutouts (2) 2 memory module
3 notch 4 tab

NOTICE: To avoid damage to the memory module, press the module straight down into the connector while you apply

equal force to each end of the module.
