Both STBY LED and BOOT LED are AOpen’s considerate designs that aim at providing you friendly system information. The STBY
LED will light up when power is provided to the motherboard. This is a convenient indication for you to check the system power
status in many circumstances such as power on/off, stand-by mode and RAM power status during Suspend to RAM mode
.
BOOT LED will keep blinking when you power the system on and when your system is under POST (Power-On Self Test)
. After
POST diagnoses everything alright and finishes the booting, the LED will stay on otherwise it will remain flashing to warn you that
mistakes have occurred during POST.
BOOT LED
Warning: Do not install or remove the
DIMM module or others devices when
the STBY LED lights on.
