Soft-Off by PWRBTN
This field defines the power-off mode when using an ATX power
supply. The Instant Off mode allows powering off immediately upon
pressing the power button. In the Delay 4 Sec mode, the system powers
off when the power button is pressed for more than four seconds or
enters the suspend mode when pressed for less than 4 seconds.
PM Timers and IRQ Wakeup Events
The HDD, FDD, COM, LPT Ports, and PCI PIRQ are I/O events that can
prevent the system from entering a power saving mode or can awaken
the system from such a mode. When an I/O device wants to gain the
attention of the operating system, it signals this by causing an IRQ to
occur. When the operating system is ready to respond to the request, it
interrupts itself and performs the service.
