Power Management Setup Option 31
Figure 3.12 Power Management Setup menu
ACPI Function
This mainboard supports ACPI (Advanced Configuration and Power management Interface). Use this item to enable
or disable the ACPI feature. The default setting is Enabled.
ACPI Suspend Type
Use this item to define how the 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 excep-
tion of a refresh current to the system memory. The default setting is S1(POS).
Power Management Option
This item acts like a master switch for the power-saving modes and hard disk timeouts. If this item is set to Max Sav-
ing, 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 define timeouts for the power-saving modes. The default
setting is Min Saving.
HDD Power Down
The IDE hard drive will spin down if it is not accessed within a specified length of time. Options are from 1 Min to 15
Min, and Disabled. The default setting is Disabled.
Suspend Mode
The CPU clock will be stopped and the video signal will be suspended if no Power Management events occur for a
specified length of time. Full power function will return when a Power Management event is detected. Options are
from 1 Min to 1 Hour and Disabled. The default setting is Disabled.
NOTE
ACPI is a power management specification that makes hardware status informa-
tion available to the operating system. ACPI enables a PC to turn its peripherals
on and off for improved power management. It also allows the PC to be turned
on and off by external devices, so that mouse or keyboard activity wakes up the
PT-5500.
