Interpreting system validation diagnostic front panel LEDs and
audible codes
During the system validation phase that occurs at system startup, the BIOS validates the functionality of
the following subsystems and conditions:
System board power
Processor failure
BIOS corruption
Memory failure
Graphics failure
System board failure
BIOS authentication failure
If an error is detected, specic patterns of long and short blinks, accompanied by long and short beeps (where
applicable) are used to identify the error. These patterns will make up a two part code:
Major – the category of the error
Minor – the specic error within the category
NOTE: Single beep/blink codes are not used.
Number of long beeps/blinks Error category
1 Not used
2 BIOS
3 Hardware
4 Thermal
5 System board
Patterns of blink/beep codes are determined by using the following parameters:
1 second pause occurs after the last major blink.
2 second pause occurs after the last minor blink.
Beep error code sequences occur for the rst 5 iterations of the pattern and then stop.
Blink error code sequences continue until the computer is unplugged or the power button is pressed.
NOTE: Not all diagnostic lights and audible codes are available on all models.
The red LED blinks to represent the major error category (long blinks). The white LED blinks to represent
the minor error category (short blinks). For example, ‘3.5’ indicates 3 long red blinks and 5 short white blinks
to communicate the processor is not detected.
