54Power Management Setup Option
This option displays items that let you control the system power
management. Operating systems take care of much of the
power management. This mainboard supports ACPI (advanced
configuration and power interface). The system has various
power saving modes including powering down the hard disk,
turning off the video, suspending to RAM, and a software power
down that allows the system to be automatically resumed by
certain events.
Power Management Timeouts
The power-saving modes can be controlled by timeouts. If the
system is inactive for a time, the timeouts begin counting. If the
inactivity continues so that the timeout period elapses, the
system enters a power-saving mode. If any item in the list of
Reload Global Timer Events is Enabled, then any activity on
that item will reset the timeout counters to zero.
Wake Up Calls
If the system is suspended, or has been powered down by
software, it can be resumed by a wake up call that is generated
by incoming traffic to a modem, a LAN card, a PCI card, or a
fixed alarm on the system realtime clock.
ACPI Suspend Type Default: S1 (POS)
Use this item to define how your system suspends. In the
default, S1(POS), the suspend mode is equivalent to a software
power down. If you select S3 (STR), the suspend mode is a
suspend to RAM – the system shuts down with the exception of
a refresh current to the system memory.
Power Management Default: Define
This item acts like a master switch for the power-saving modes
and hard disk timeouts. If this item is set to Max Saving, power-
saving modes occur after a short timeout. If this item is set to
Min Saving, power-saving modes occur after a longer timeout. If
the item is set to User Define, you can insert your own timeouts
for the power-saving modes.
Video Off Method Default: DPMS
This item defines how the video is powered down to save
power. As a default, this is set to DPMS (display power
management software).
Video Off In Suspend Default: Yes
This option defines if the video is powered down when the
system is put into suspend mode.
