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: Disconnect all power sources before opening the computer cover or panels. After you
finish working inside the computer, replace all covers, panels, and screws before connecting to
the power source.
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.
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.

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.

Diagnostics
If you experience a problem with your computer, run the ePSA diagnostics before contacting Dell for
technical assistance. The purpose of running diagnostics is to test your computer's hardware without
requiring additional equipment or risking data loss. If you are unable to fix the problem yourself, service
and support personnel can use the diagnostics results to help you solve the problem.
Enhanced Pre-Boot System Assessment (ePSA) Diagnostics
The ePSA diagnostics (also known as system diagnostics) performs a complete check of your hardware.
The ePSA is embedded with the BIOS and is launched by the BIOS internally. The embedded system
diagnostics provides a set of options for particular devices or device groups allowing you to:
• Run tests automatically or in an interactive mode
• Repeat tests
38
• Display or save test results
• Run thorough tests to introduce additional test options to provide extra information about the failed
device(s)
• View status messages that inform you if tests are completed successfully
• View error messages that inform you of problems encountered during testing
CAUTION: Use the system diagnostics to test only your computer. Using this program with other
computers may cause invalid results or error messages.
NOTE: Some tests for specific devices require user interaction. Always ensure that you are present
at the computer terminal when the diagnostic tests are performed.
1. Power-on the computer.
2. As the computer boots, press the <F12> key as the Dell logo appears.
3. On the boot menu screen, select the Diagnostics option.
The Enhanced Pre-boot System Assessment window is displayed, listing all devices detected in the
computer. The diagnostics starts running the tests on all the detected devices.
4. If you wish to run a diagnostic test on a specific device, press <Esc> and click Yes to stop the
diagnostic test.
5. Select the device from the left pane and click Run Tests.
6. If there are any issues, error codes are displayed.
Note the error code and contact Dell.
Troubleshooting Your Computer
You can troubleshoot your computer using indicators like diagnostic lights, beep codes, and error
messages during the operation of the computer.
Power LED Diagnostics
The power button LED located on the front of the chassis also functions as a bicolored diagnostic LED.
The diagnostic LED is only active and visible during the POST process. Once the operating system starts
to load, it is no longer visible.
Amber LED blinking scheme – The pattern is 2 or 3 blinks followed by a short pause then x number of
blinks up to 7. The repeated pattern has a long pause inserted in the middle. For example 2,3 = 2 amber
blinks, short pause, 3 amber blinks followed by long pause then repeats.

3,5 memory modules are detected, but a memory configuration or compatibility error
3,6 possible system board resource and/or hardware failure
3,7 some other failure with messages on screen
Beep Code
The computer can emit a series of beeps during start-up if the display does not 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.
