Wake Up Event
Wake Up 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.
VGA
When
On,
you can set the VGA awakens the system.
LPT & COM
When
On of
LPT & COM, any activity from one of the listed system peripheral
devices or IRQs wakes up the system.
HDD & FDD
When
On of HDD
& FDD, any activity from one of the listed system peripheral
devices wakes up the system
.
PCI Master
When
On of PCI Master
, any activity from one of the listed system peripheral
devices wakes up the system.
Wake Up On LAN/Ring
An input signal on the serial Ring Indicator (RI) line (in other words, an incoming
call on the modem) and LAN WOL awakens the system from a soft off state.
RTC Alarm Resume
When
Enabled,
your can set the date and time at which the RTC (real-time clock)
alarm awakens the system from Suspend mode.
The following is a list of IRQ’s,
I
nterrupt
R
e
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.
48
When the operating system is ready to respond to the request, it interrupts itself
and performs the service.
When set
On
, activity will neither prevent the system from going into a power
management mode nor awaken it.
