Using system diagnostics

If you experience a problem with your system, run the system diagnostics before contacting Dell for

technical assistance. The purpose of running system diagnostics is to test your system 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.

Dell Embedded System Diagnostics

NOTE: The Dell Embedded System Diagnostics is also known as Enhanced Pre-boot System

Assessment (ePSA) diagnostics.

The Embedded System Diagnostics provides a set of options for particular device groups or devices

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

When to use the Embedded System Diagnostics

Run the Embedded System Diagnostics (ePSA) if your system does not boot.

Running the Embedded System Diagnostics

Run the Embedded System Diagnostics (ePSA) if your system does not boot. The embedded system

diagnostics program is run from the Dell Lifecycle Controller.

Prerequisites

If a major component or device in the system does not operate properly, running the embedded system

diagnostics may indicate component failure.

CAUTION: Use the embedded system diagnostics to test only your system. Using this program

with other systems may cause invalid results or error messages.

Steps

1. As the system boots, press F11.

2. Use the up and down arrow keys to select System Utilities → Launch Dell Diagnostics.

The ePSA Pre-boot System Assessment window is displayed, listing all devices detected in the

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