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.
10 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.

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).
124 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 installed.
– Remove and reinstall the memory modules (see "Replacing or Adding
a Memory Module" on page 90).
– Remove and reinstall any cards (see "Cards" on page 29).
• Eliminate interference. Some possible causes of interference are:
– Power, keyboard, and mouse extension cables
– Too many devices on a power strip
– Multiple power strips connected to the same electrical outlet
Beep Codes
Your computer might emit a series of beeps during start-up if the monitor
cannot display errors or problems. This series of beeps, called a beep code,
identifies a problem. For example, beep code 1-3-1 (one possible beep code)
consists of one beep, a burst of three beeps, and then one beep. This beep
code tells you that the computer encountered a memory problem.
Reseating the memory modules may correct the following beep code errors. If
the problem persists, contact Dell™ (see "Contacting Dell" on page 159) for
obtaining technical assistance.
If your computer emits a series of beeps during start-up:
1
Write down the beep code.
