4.When the tests are completed, if you are running the Dell Diagnostics from the Drivers and Utilities disc, remove the disc.

5.Close the test screen to return to the Main Menu screen. To exit the Dell Diagnostics and restart the computer, close the Main Menu screen.

Power Button Light Codes

The power LED located in the power button on the front of the computer illuminates and blinks or remains solid to indicate five different states:

No light—System is in the off state (S5, or mechanical (AC power not applied) OFF).

Solid Amber—System fault, but Power Supply is good—normal operating state (S0 ).

Blinking Amber—System fault error condition including Power Supply (only +5VSB working), Vreg failure, missing or bad CPU.

Blinking Green—System is in power saving states S1, S3 or S4. (Blink rate is 1Hz). No fault/error condition.

Solid Green—System is fully functional and is in S0 (ON) state.

Diagnostic Light Codes

Four (4) single color lights are incorporated on the front control panel to serve as a diagnostic aid for troubleshooting systems exhibiting No Post/No Video symptoms. The lights do not report runtime errors.
