Wake Up Events
The HDD, FDD, COM, LPT Ports, and PCI PIRQ 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.
