This chapter provides procedures for removing and installing the components in your computer. Unless otherwise noted, each procedure assumes that the
following conditions exist:
lYou have performed the steps in Turning Off Your Computer and Safety Instructions.
lYou have read the safety information that ships with your computer.
l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 Setup 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 following tools:
lSmall Phillips screwdriver
lSmall flat-blade screwdriver
Turning 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.

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).

3. Disconnect all telephone or network cables from the computer.

CAUTION: To avoid losing data, save and close all open files and exit all open programs before you turn off your computer.
WARNING: 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.
CAUTION: 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.
CAUTION: 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.
CAUTION: To avoid damaging the computer, perform the following steps before you begin working inside the computer.
CAUTION: To disconnect a network cable, first unplug the cable from your computer and then unplug the cable from the network device.

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.


CAUTION: 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.
