Working on Your Computer
Before Working Inside Your Computer
Use the following safety guidelines to help protect your computer from potential
damage and to help to ensure your personal safety. Unless otherwise noted,
each procedure included in this document assumes that the following
conditions exist:
• 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.
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: Many repairs may only be done by a certified service technician. You
should only perform troubleshooting and simple repairs as authorized in your
product documentation, or as directed by the online or telephone service and
support team. Damage due to servicing that is not authorized by Dell is not covered
by your warranty. Read and follow the safety instructions that came with the
product.
CAUTION: To avoid electrostatic discharge, ground yourself by using a wrist
grounding strap or by periodically touching an unpainted metal surface, such as a
connector on the back of the computer.
CAUTION: Handle components and cards with care. Do not touch the components
or contacts on a card. Hold a card by its edges or by its metal mounting bracket.
Hold a component such as a processor by its edges, not by its pins.

Page 8
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.
NOTE: The color of your computer and certain components may appear differently
than shown in this document.
To avoid damaging your computer, perform the following steps before you begin
working inside the computer.
1. Ensure that your work surface is flat and clean to prevent the computer
cover from being scratched.
2. Turn off your computer (see Turning Off Your Computer).
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 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 computer is unplugged to
ground the system board.
6. Remove the cover.
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.
Recommended Tools
The procedures in this document may require the following tools:
• Small flat-blade screwdriver
• Phillips screwdriver
• Small plastic scribe
• Flash BIOS update program media

• In Windows XP:
Click Start → Turn Off Computer → Turn Off . The computer turns off
after the operating system shutdown process is complete.
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 6 seconds to turn them off.
After Working Inside Your Computer
After you complete any replacement procedure, ensure you connect any
external devices, cards, and cables before turning on your computer.
1. Replace the cover.
CAUTION: To connect a network cable, first plug the cable into the network device
and then plug it into the computer.
2. Connect any telephone or network cables to your computer.
3. Connect your computer and all attached devices to their electrical outlets.
4. Turn on your computer.

The boot menu enhancements are as follows:
• Easier access — Although the <Ctrl><Alt><F8> keystroke still exists and can
be used to call up the menu, simply press <F12> during system boot to
access the menu.
• User prompting — Not only is the menu easy to access, when you are
prompted to use the keystroke on the BIOS splash screen (see image
below). The keystroke is not "hidden".
• Diagnostics options — The boot menu includes two diagnostic options, IDE
Drive Diagnostics (90/90 Hard Drive Diagnostics) and Boot to the Utility
55
Page 56
Partition. The benefit here is that you do not have to remember the
<Ctrl><Alt><D> and <Ctrl><Alt><F10> keystrokes (although they still work).
NOTE: The BIOS features an option to disable either or both of the keystroke
prompts under the System Security / Post Hotkeys submenu.
When you enter the <F12> or <Ctrl><Alt><F8> keystroke correctly, the computer
beeps. The key sequence invokes the Boot Device Menu.
Since the one-time boot menu only affects the current boot, it has the added
benefit of not requiring the technician to restore the customer's boot order after
completing troubleshooting.
Timing Key Sequences
The keyboard is not the first device initialized by Setup. As a result, if you press
a keystroke too early, you lock out the keyboard. When this happens, a
keyboard error message appears on the monitor, and you cannot restart the
system with the <Ctrl><Alt><Del> keys.
To avoid this scenario, wait until the keyboard is initialized before pressing the
keystroke. There are two ways to know that this has happened:
• The keyboard lights flash.
• The "F2=Setup" prompt appears in the top right-hand corner of the screen
during boot.
The second method is good if the monitor is already warmed up. If it is not, the
system often passes the window of opportunity before the video signal is
visible. If this is the case, rely on the first method—the keyboard lights—to
know the keyboard is initialized.

Beep Codes and Text Error Messages
The OptiPlex BIOS is capable of displaying error messages in plain English,
along with beep codes. If the BIOS determine the previous boot was
unsuccessful, it displays an error message similar to the following:

Diagnostic LEDs
NOTE: The diagnostic LEDs only serve as an indicator of the progress through the
Power-on Self-Test (POST) process. These LEDs do not indicate the problem that
caused the POST routine to stop.
The diagnostic LEDs are located on the front of the chassis next to the power
button. These diagnostic LEDs are only active and visible during the POST
process. Once the operating system starts to load, they turn off and are no
longer visible.
The system now includes pre-POST and POST LEDs in an attempt to help
identifying a possible problem with the system easier and more accurate.
NOTE: The diagnostic lights will blink when the power button is amber or off, and
will not blink when it is blue. This has no other significance.

Beep Codes
The computer can emit a series of beeps during start-up if the display cannot
show errors or problems. These series of beeps, called beep codes, identify
various problems. The delay between each beep is 300 ms, the delay between
each set of beeps is 3 sec, and the beep sound lasts 300 ms. After each beep
and each set of beeps, the BIOS should detect if the user presses the power
button. If so, BIOS will jump out from looping and execute the normal shutdown
process and power system.
