vide some system controls.

Use: This button is configured by the CMOS Setup Utility by the “Soft-
Off Mode by PWR-BTTN” line in the Power Management section.
Depending on the setting, the power button will function in one of two
modes, instant on/off or instant on/4 second delay off. In the delay ode,
when you push the power button for less than 4 seconds when the system

this mode, you have to push the button for more than 4 seconds to turn the
system power off.
