Standby Mode
This Green PC power saving function is user configurable only when
the Power Management category is set to User Defined. It is used to
define the idle time that elapses before the system enters the Standby
mode. When enabled and after the set time of system inactivity, the
fixed disk drive and the video will be shut off while all other devices still
operate at full speed.
Suspend Mode
This Green PC power saving function is user configurable only when
the Power Management category is set to User Defined. It is used to
define the idle time that elapses before the system enters the Suspend
mode. When enabled and after the set time of system inactivity, all de-
vices except the CPU will be shut off.
HDD Power Down
This Green PC power saving function is user configurable only when
the Power Management category is set to User Defined. It is used to
define the continuous HDD idle time that elapses before the HDD en-
ters the power saving mode (motor off). When enabled and after the set
time of system inactivity, the hard disk drive will be powered down while
all other devices remain active.
IRQ3-IRQ15 (Wake Up Events In Doze & Standby, and Power
Down & Resume Events)
These 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 enabled, even when the system is in a
power saving 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.
