Back Panel Lights

When you turn on your computer, it performs a power-on self-test (POST), which is a series of self-diagnostic checks. A successful POST ends with a single beep that signifies the start of normal operation. If the computer fails to emit the single beep or appears to stop responding during POST, a series of lights located at the rear of the computer can help you understand which POST test failed or why the computer stopped responding. These lights indicate problems encountered during POST only, not during normal operation.

CAUTION: Before servicing any components inside your computer, see “Safety First—For You and Your Computer.”

The light patterns described in the following table can help you determine what to do to resolve the problem. If a problem resolution requires you to open the computer chassis, see “Finding Solutions” for procedures you need to complete prior to performing the suggested resolution. If the problem persists after you perform the suggested problem resolution(s), contact Dell for further help.

The following table lists the codes for the back panel diagnostic lights, gives their probable causes, and offers suggested corrective actions. The light patterns are shown as they appear on the back of the desktop chassis (vertical position).
