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

NOTE:

The

Enhanced Pre-boot System Assessment

window displays, listing all devices detected in the computer. The

diagnostics starts running the tests on all the detected devices.

Running ePSA diagnostics

Invoke diagnostics by either of the methods that are suggested below:

●

Tap F12

key on keyboard, as the Dell splash screen appears, until you get the message

Diagnostic Boot Selected.

○

On the one-time boot menu screen, use the Up/Down arrow key to select the

Diagnostics

option and then press

Enter

.

●

Press and Hold

Function (Fn)

key on the keyboard and press the

Power button

to power on the system.

ePSA User Interface

This section contains information on ePSA 3.0’s Basic and Advanced Screen.

ePSA opens the basic screen on start. You can switch to the advanced screen using the arrow icon at the bottom of the
screen. The advanced screen shows detected devices on the left column. Specific test can be included or excluded only in the
interactive mode.

ePSA Basic Screen

The Basic Screen has minimal controls which allows easy navigation for the user to start or stop the diagnostics.
