Memory: DIMM_LED
IDE: IDE_LED
SATA: SA_LED
PCIe x16/x8: PE_LED
PCIe x4/x1: PE1_LED
PCI: PCI_LED
ACPI LEDs
The 4 embedded ACPI LEDs indicate the system power status (S0, S1, S3, S4, S5) to prevent potential hard-
ware damage due to improper plug/unplug actions.

will be illuminated when an excessive overvoltage or overloading occurs.
CPU VTT:
GD1: Normal working conditions (green LED)
GD2: Excessive overvoltage or overloading (yellow LED)
Memory:
MD1: Normal working conditions (green LED)
