RTC Timer to Power On the System
The RTC installed on the system board allows your system to
automatically wake up on the set date and time. Set the date and
time you would like your system to power on in the “Resume By
Alarm” field of the Power Management Setup (Chapter 2).
Modem Wake-up/Ring-on
The Modem Wake-Up feature allows the sleeping (Suspend mode)
PC to wake-up to respond to incoming calls. The Modem Ring-on
feature allows the Soft Power Down (Soft-Off) PC to power on to
respond to incoming calls. Enable this function in the “Resume By
Ring” field of the Power Management Setup (Chapter 2). Make sure
to select an IRQ channel for the external modem in the “Modem
Use IRQ” field of the Power Management Setup and set JP11 to
the COM port where the modem is connected (Chapter 3).
Note:
This feature supports external modem only.
