1-6 Power Conﬁ guration Settings

This section describes the features of your motherboard that deal with power and

power settings.

Microsoft OnNow

The OnNow design initiative is a comprehensive, system-wide approach to system

and device power control. OnNow is a term for a PC that is always on but appears

to be off and responds immediately to user or other requests.

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 a USB keyboard is the only keyboard in the system, it will function like a normal

keyboard during system boot-up.

Main Switch Override Mechanism

The power button can function as a system suspend button. When the user

depresses the power button, the system will enter a SoftOff state. The monitor

will be suspended and the hard drive will spin down. Depressing the power button

again will cause the whole system to wake-up. During the SoftOff state, the 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 depress and hold the

power button for 4 seconds. The power will turn off and no power will be provided

to the motherboard.

Wake-On-LAN (WOL)

Wake-On-LAN is deﬁ ned as the ability of a management application to remotely

power up a computer that is powered off. Remote PC setup, up-dates and access

tracking can occur after hours and on weekends so that daily LAN trafﬁ c is kept

to a minimum and users are not interrupted. The motherboard has a 3-pin header

(WOL) to connect to the 3-pin header on a Network Interface Card (NIC) that has

WOL capability. Wake-On-LAN must be enabled in BIOS.
