Power management lets you set up your computer to save
electricity when it is not actively in use by putting the system into
progressively greater power saving modes. In the power manage-
ment scheme there are four system states which proceed in the
following sequence:
Disabled
There are two selections for Power Management (Mode):
Disabled
SMI
With the exception of Disabled, SMI selections have "fixed-
mode" settings. Therefore, when PM is set to Disabled, some
items which are predefined will become unmodifiable.
When enabled and after the selected time of system inactivity, the
hard disk drive will be powered down while all other devices will
remain active.
This sets the period of system inactivity after which the system
goes into Doze mode, the most limited power saving state. The
settings range from 10 seconds to 2 hours and can be set manual-
ly when power management is in SMI. The default setting is
Disabled. When the system goes into power saving mode, power
management will skip to the next mode in the sequence if this is
disabled.
