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.
NOTE: Before proceeding download and install the latest BIOS version from support.dell.com

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.
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 is displayed, 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.
