1.1.2 Intelligence / Intelligence / Intelligente Ausstattungsteile
Automatic Fan On/Off Control
The CPU fan will automatically turn off when the system enters the
Suspend mode.This prevents system overheat and prolongs fan life.
Dual Function Power Button
Depending on the setting in the BIOS setup, this switch will allow
your system to enter the Soft-Off or Suspend mode.
External Modem Ring-on
The Modem Ring-on feature allows the system that is in the
Suspend mode or Soft Power Off mode to wake-up/power-on to
respond to incoming calls. This feature supports external modem
only.
RTC Timer to Power-On the System
The RTC installed on the system board allows your system to
automatically power-on on the set date and time.
Wake-On-LAN Ready
The Wake-On-LAN function allows the network to remotely wake
up a Soft Power Down (Soft-Off) PC. Your LAN card must support
the remote wakeup function.
Important:
The 5VSB power source of your power supply must support
720mA (minimum).
Wake-On-Keyboard
This function allows the keyboard to power-on the system. Refer to
sections 2.3 (chapter 2) and 3.9 (chapter 3) for more information.
Important:
The power button will not function once a keyboard password
has been set in the KB Power On Password field of the
Integrated Peripherals setup. You must type the password to
power-on the system.
Virus Protection
Most viruses today destroy data stored in hard drives. The system
board is designed to protect the boot sector and partition table of
your hard disk drive.
