Vostro 3401 Service Manual

Enhanced Pre-Boot System Assessment (ePSA) diagnostics

About this task

The SupportAssist diagnostics (also known as system diagnostics) performs a complete check of your hardware. The SupportAssist diagnostics 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
NOTE: The SupportAssist window displays, listing all devices detected in the computer. The diagnostics starts running the tests on all the detected devices.
