4.1 BIOS Front-panel Power LED Codes
The front-panel power LED blinks off and on to display messages. For example, the
power LED is on when the system is powered on, and blinks off for 0.5 second when
processor initialization is complete. In addition, whenever a recoverable error occurs
during POST, the BIOS causes the front-panel power LED to blink an error message
describing the problem (see Table 31).
