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
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
≥
720mA.
