About Your System
Diagnostic Lights
The four diagnostic indicator lights on the system front panel display error
codes during system startup. Table 1-5 lists the causes and possible corrective
actions associated with these codes. A highlighted circle indicates the light is
on; a non-highlighted circle indicates the light is off.
NOTE:
If the power LEDs blink amber, there is a problem with the power supply. If
the power LED shows a solid amber, a BIOS failure occurred before Power-On Self
Test (POST).
