Video OFF Method
This field defines the video off features. There are three options
available:
V/H SYNC + Blank
DPMS
Blank Screen
Doze Mode
When enabled and after the set time of system inactivity, the CPU
clock will run at slower speed while all other devices still operate at full
speed.
Standby Mode
When enabled and after the set time of system inactivity expires, the
fixed disk drive and the video would be shut off while all other devices
still operate at full speed.
Suspend Mode
When enabled and after the set time of system inactivity, all devices
except the CPU will be shut off.
HDD Power Down
When enabled and after the set time of system inactivity expires, the
hard disk drive will be powered down while all other devices remain
active.
Wake Up Events In Doze & Standby
This section sets the wake-up call of the system. If activity is detected
from any enabled IRQ channels in the left-hand group, the system
wakes up from suspend mode.
Power Down & Resume Events
This section are I/O events which can prevent the system from entering
a power saving mode or can awaken the system from such a 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. The default value is Off. When set to On, activity
will neither prevent the system from going into a power management
mode nor awaken it.
