Auto-Switching Voltage Regulator for the CPU Core
The 3-phase-switching voltage regulator for the CPU core can support up to
60A current and auto-sense voltage IDs ranging from 1.1V to 1.85V. This
will allow the regulator to run cooler and thus make the system more stable.
1-4 Power Configuration Settings
This section describes features of your motherboard that deal with power
and power settings.
Slow Blinking LED for Suspend-State Indicator
When the CPU goes into a suspend state, the chassis power LED will start
blinking to indicate that the CPU is in suspend mode. When the user presses
any key, the CPU will wake-up and the LED will automatically stop blinking
and remain on.
BIOS Support for USB Keyboard
If the USB keyboard is the only keyboard in the system, it keyboard will
function like a normal keyboard during system boot-up.
Main Switch Override Mechanism
When an ATX power supply is used, the power button can function as a
system suspend button. When the user presses the power button, the
system will enter a SoftOff state. The monitor will be suspended and the
hard drive will spin down. Pressing the power button again will cause the
whole system to wake-up. During the SoftOff state, the ATX power supply
provides power to keep the required circuitry in the system alive. In case
the system malfunctions and you want to turn off the power, just press and
hold the power button for 4 seconds. The power will turn off and no
power will be provided to the motherboard.
Wake-On-Ring (WOR) Header
Wake-up events can be triggered by a device such as the external modem
ringing when the system is in the SoftOff state. Note that external modem
ring-on can only be used with an ATX 2.01 (or above) compliant power
supply.
