following conditions exist:
• You have performed the steps in "Turning Off Your Computer" on page 11
and "Safety Instructions" on page 12.
• You have read the safety information that ships 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 Setup
Guide that shipped with your computer or see the Dell Support website at
support.dell.com/manuals.
Recommended Tools
The procedures in this document may require the following tools:
• Small Phillips screwdriver
• Small flat-blade screwdriver
.
Turning Off Your Computer
CAUTION: 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.
Before You Begin 11
Page 12
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.
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.
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" on page 11).
CAUTION: 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.
12 Before You Begin
Page 13
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.
