Problem Description

Suggested Resolution

During normal operation, all of the diagnostic lights turn on and then turn off before the system starts.

If all four diagnostic lights stay on and the power button remains amber, a possible processor power or connection error has occurred.

NOTE: If all of the diagnostic lights turn on then off and the system does not start, there may be a problem with the power supply or with the processor. For other possible solutions, see "Power Problems" in your Owner's Manual.

If the system does not start, plug the computer into a working electrical outlet. Also see "Power Problems" in your Owner’s Manual.

Unplug the power supply and check the 4-pin processor power cable connection (see "System Board Components" on page 65).

If there are no power problems and the system does not start, contact Dell for technical assistance.
