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:
●
AC adapter
●
System board power
●
Processor failure
●
BIOS corruption
●
Memory failure
●
Graphics failure
●
System board failure
●
BIOS authentication failure
If an error is detected, specific 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 specific error within the category
NOTE:
Single beep/blink codes are not used.
Number of long beeps/blinks
