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.
Warning:
When the DRAM Power LED and/or Standby Power LED lit red,
it indicates that power is present on the DIMM sockets and/or
PCI slots. Power-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.
