Notes:
  • One of the most common tasks requested when troubleshooting a system is to update the system Basic Input/Output System (BIOS) also called the system setup.
    It is strongly suggested that the BIOS be updated to the most current version available before running diagnostics. For more information, refer to our guide to update the Dell BIOS/UEFI.
  • Make note of the ePSA error and validation code.
  • The last three digits in the code are called the beep code. These beeps occur when the system is unable to display a message. For example, error code 2000-4224 has a beep code of 224 which may be manifest by 2 beeps – pause - 2 beeps – pause - 4 beeps. In this case, the beeps are trying to inform the operator that the hard drive test was unsuccessful.
