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.

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

• 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.

You can launch the ePSA diagnostics by two ways:

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 displays, 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.

1. Shutdown the computer.

2. Press and hold the <fn> key, while pressing the power button, and then release both.

The Enhanced Pre-boot System Assessment window displays, listing all devices detected in the

computer. The diagnostics starts running the tests on all the detected devices.

3. On the boot menu screen, select the Diagnostics option.

The Enhanced Pre-boot System Assessment window displays, 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.
