5 Power-On Self-Test and Error Messages

Lights on the Hardware Control Panel

Lights on the Hardware Control Panel

When the computer is first powered on, the power-onlight on the status panel illuminates yellow for about a second before changing to green. This change of color is caused by the execution of an instruction early in the System BIOS code.

If the light remains at yellow, therefore, it indicates a failure of the processor or the System ROM in the instruction-fetch process. Check that the processor is correctly seated in its socket, and that the memory DIMMS and accessory cards are properly installed.
