PM Wake Up Events
Press to enter the sub-menu and the following screen appears:
IRQ [3-7,9-15], NMI & IRQ 8 Break Suspend
This setting enables/disables the monitoring of the specified IRQ line. If
set to Enabled, the activity of the specified IRQ line will prevent the
system from entering power saving modes or awaken it from power sav-
ing modes. Setting options: Disabled, Enabled.
Note: IRQ (Interrupt Request) lines are system resources allocated
to I/O devices. When an I/O device needs to gain attention of the
operating system, it signals this by causing an IRQ to occur. After
receiving the signal, when the operating system is ready, the system
will interrupt itself and perform the service required by the I/O device.
