Power Down & Resume Events
Power Down and Resume events are I/O events whose occurrence can prevent the
system from entering a power saving mode or can awaken the system from such a mode.
In effect, the system remains alert for anything which occurs to a device which is
configured as
On
, even when the system is in a power down mode.
The following is a list of IRQ,
I
nterrupt

Q
uests, which can be exempted much as the
COM ports and LPT ports above can. 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.
As above, the choices are
On
and
Off. Off
is the default.
When set
On
, activity will neither prevent the system from going into a power
management mode nor awaken it.
IRQ3 (COM 2 )
IRQ4 (COM 1)
IRQ5 (LPT 2)
IRQ6 (Floppy Disk)
IRQ7 (LPT 1)
IRQ8 (RTC Alarm)
IRQ9 (IRQ2 Redir)
IRQ10 (Reserved)
IRQ11 (Reserved)
IRQ12 (Reserved)
IRQ13 (Coprocessor)
IRQ14 (Hard Disk)
IRQ15 (Reserved)
