Run the Embedded System Diagnostics (ePSA)
if your system does not boot. The embedded system diagnostics program
is run from the Dell Lifecycle Controller.
Prerequisites
If a major
component or device in the system does not operate properly, running
the embedded system diagnostics may indicate component failure.
CAUTION: Use
the embedded system diagnostics to test only your system. Using this
program with other systems may cause invalid results or error messages.
Steps
As the system boots, press F11.
Use the up and down arrow keys to select System Utilities > Launch Dell Diagnostics.
The ePSA Pre-boot System Assessment window is displayed, listing all devices detected in the system.
The diagnostics starts running the tests on all the detected devices.
