2-28 System Configuration and Setup
Windows 2000 Hibernate
Use the Hibernate window to enable hibernate support, see the amount of free disk space, and
the amount of disk space required to hibernate. When the system hibernates, it performs a save-
to-disk or save-to-file (STF). The current working environment is saved to the hard disk. Use the
Power button to resume from hibernation and the system returns to its previous state.
Windows 98/2000 Power Management States
ACPI uses different levels or states of power management. The power management states occur
automatically, based on the system’s default settings, or manually, when invoked. Settings are
configurable to occur while on battery power or AC power.
The Windows 98/2000 ACPI power management states include:
!
LCD timeout — manages power at the lowest level by shutting down the LCD.
!
Standby — also known as Save-to-RAM (STR), Standby manages power by saving the
current working environment to memory and shutting down most system devices.
Conserves more power than an LCD timeout.
!
Hibernate — also known as save-to-disk, or save-to-file (STF) manages power by saving
the current working environment to an area on the hard disk, then powering off the system.
Conserves the most battery power.
Recognizing the Windows 98/2000 Power Management States
It is important to recognize the system’s behavior when in each of these power management
states. The following table describes the system behavior for each power management state.
