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
