2.6-I. Soft Power Connector

The soft power connector is part of jumper block J12 (pins 13 and 15). This board uses the chipset for power management, including turning on and off the system. If the power button function option in the BIOS Power Management menu is set to “On/Off” (which is the default), pressing the power button once after the BIOS has booted up will turn the system on and off. If the power button function is set to Sus- pend, pressing the power button once will wake up the system or send it to Suspend mode. In this case, you cannot turn the system off unless you shut down through the Windows operating system or you hold the power button down for four seconds (BIOS-dependent feature).

2.6-J. Hardware Reset Switch Connector Installation

The reset switch on your chassis case provides you with the Hardware Reset function, which is the same as power on/off, except that the system will immediately execute a cold start after the reset button is pushed. The reset switch needs to be connected to jumper block J12 (pins 7 and 9).
