information, such as CPU and system voltages, temperatures, and fan status
through the onboard hardware ASUS ASIC and the bundled ASUS PC Probe.
Dual Function Power Button: Pushing the power button for less than 4 seconds
when the system is in the working state places the system into one of two states:
sleep mode or soft-off mode, depending on the BIOS or OS setting (See PWR
Button < 4 Secs in 4.5 Power Menu). When the power button is pressed for
more than 4 seconds, the system enters the soft-off mode regardless of the BIOS
setting.
