Diagnostic LED
DRAM Power LED
This LED will light when the system’s power is on.
Standby Power LED
This LED will light when the system is in the standby mode.
Diagnostic LED
The Diagnostic LED displays POST codes. POST (Power-On Self Tests) which is
controlled by the BIOS is performed whenever you power-on the system. POST
will detect the status of the system and its components. Each code displayed on
the LED corresponds to a certain system status.
Important:
When the DRAM Power LED and/or Standby Power LED lit red, it indi-
cates that power is present on the DIMM sockets and/or PCI slots. Pow-
er-off the PC then unplug the power cord prior to installing any memory
modules or add-in cards. Failure to do so will cause severe damage to
the motherboard and components.
