Dual Function Power Button
Depending on the setting in the “Soft-Off By PWRBTN” 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 com-
ing from an external modem or respond to calls from a modem
PCI card that uses the PCI PME (Power Management Event) sig-
nal 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.
