A BIOS Error Messages 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 9). Table 9.
