On, Off When the system is in Doze or Standby mode, you may disable
activity monitoring of some common interrupt requests so they do
not wake up the system.
The default wake-up event is keyboard activity. In these wake-up
event fields, you can turn On or Off four commonly used interrupts.
For example, if you have a modem on IRQ3, you can turn on IRQ3
as a wake-up event, so an interrupt from the modem can wake up
the system. Or you may wish to turn Off IRQ12 (the PS/2) mouse as
a wake-up event, so accidentally brushing the mouse does not
awaken the system.
