You can reduce the computer’s overall power consumption by using Power Management to
reduce power consumption when the computer is idle.
ACPI Power Management Modes
(Windows 2000 and Windows XP)
The following table describes the power states and identifies the possible Wake Up Events for the
different power management modes. Activity on any one of these events will cause the system to
wake up from it’s current power state.
■
By default, when activating Standby mode in Windows XP or Windows 2000, the computer
will go into the S3, “Suspend to RAM,” power state.
■
The Hibernate menu in Windows XP and Windows 2000 is the same as S4, “Suspend
to Disk.”
✎
For the Standby command to activate the S3 power state and not S1, all drivers must be correctly
installed.
