Automatic Chassis/Second Fan Off
The chassis fan and second fan will automatically turn off once the
system enters the Suspend mode.
Dual Function Power Button
Depending on the setting in the Soft-Off By PWR-BTTN field of
the Power Management Setup, this switch will allow the system to
enter the Soft-Off or Suspend mode.
Wake-On-Ring
This feature allows the system that is in the Suspend mode or Soft
Power Off mode to wake-up/power-on to respond to calls coming
from an external modem or respond to calls from a modem PCI
card that uses the PCI PME (Power Management Event) signal to
remotely wake up the PC.
Important:
If you are using a modem add-in card, the 5VSB power source
of your power supply must support a minimum of
≥
720mA.
