Before Working on Your Computer
This document provides procedures for removing and installing the
components in your computer. Unless otherwise noted, each procedure
assumes that:
•
You have performed the steps in "Before Working on Your Computer" on
page 9.
•
You have read the safety information that shipped with your computer.
•
When replacing a component, you have already removed the original, if
installed.
NOTE: The color of your system and certain system components may appear
differently than shown in this document.
Recommended Tools
The procedures in this document may require the following tools:
•
Small flat-blade screwdriver
•
Phillips screwdriver
•
Small plastic scribe
•
Flash BIOS update (see the Dell Support website at support.dell.com)
Before Working on Your Computer
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.
Before Working on Your Computer

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 10).
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.
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.
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.
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.

Removing the Power Supply From the Desktop Computer
1 Follow the procedure in "Before Working on Your Computer" on page 9.
2 Remove the computer cover (see "Removing the Desktop Computer
Cover" on page 21).
3 Disconnect the power cables from the system board and the drives.
CAUTION: Note the routing of the power cables underneath the tabs in the

route these cables properly when you replace them to prevent them from being
pinched or crimped.
4 Remove the two screws that attach the power supply to the back of the
computer chassis.
5 Remove the optical drive and set it aside (see "Removing the Optical Drive
From the Desktop Computer" on page 59).

NOTE: If a BIOS-update program CD is provided with a new system board, flash the
BIOS from the CD. If you do not have a BIOS-update program CD, see "Flashing the
BIOS From the Hard Drive" on page 118.
Flashing the BIOS From a CD
1 Turn on your computer.

5 When the DELL™ logo appears, press <F12> immediately.
NOTE: Keyboard failure may result when a key on the keyboard is held down
for extended periods of time. To avoid possible keyboard failure, press and
release <F12> in even intervals until the Boot Device Menu appears.
If you wait too long and the operating system logo appears, continue to
wait until you see the Microsoft® Windows® desktop, and then shut down
your computer and try again.

appropriate number on the keyboard to highlight Onboard or USB CDROM, and then press <Enter>.
NOTE: The one time boot menu feature changes the boot sequence for the
current boot only. Upon restart, the computer boots according to the boot
sequence specified in the system setup program.
CAUTION: Do not interrupt this process once it begins. Doing so may damage the
system.

Power Lights
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.
WARNING: Always unplug your computer from the electrical outlet before
opening the cover.
The power button light located on the front of the computer illuminates and
blinks or remains solid to indicate different states:
•
If the power light is green and the computer is not responding, see "Beep
Codes" on page 124.
•
If the power light is blinking green, the computer is in standby mode. Press
a key on the keyboard, move the mouse, or press the power button to
resume normal operation.
•
If the power light is off, the computer is either turned off or is not
receiving power.
–
Reseat the power cable into both the power connector on the back of
the computer and the electrical outlet.
–
If the computer is plugged into a power strip, ensure the power strip is
plugged into an electrical outlet and the power strip is turned on.
–
Bypass power protection devices, power strips, and power extension
cables to verify if the computer turns on properly.
–
Ensure the electrical outlet is working by testing it with another
device, such as a lamp.
–
Ensure the main power cable and front panel cable are securely
connected to the system board (see "System Board Components" on
page 13).
Troubleshooting

•
If the power light is blinking amber, the computer is receiving electrical
power, but an internal power problem may exist.
–
Ensure the voltage selection switch is set to match the AC power at
your location, if applicable.
–
Ensure the processor power cable is securely connected to the system
board (see "System Board Components" on page 13).
If the power light is steady amber, a device may be malfunctioning or
incorrectly
