PM Events
The VGA, LPT & COM, HDD & FDD, DMA /master, Modem Ring
Resume, RTC Alarm Resume and Primary INTR section are I/O events
which 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. The default value is
Off
. When
set On, activity will neither prevent the system from going into a power
management mode nor awaken it. The IRQ section sets the wake-up call
of the system. If activity is detected from any enabled IRQ channels in the
left-hand group, the system wakes up from suspended mode.
