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.
Warning: Do not install or remove
the DIMM module or others
devices when the STBY LED lights
on.
