2-24 System Configuration and Setup
Microsoft Windows 2000/98/Me Power Management States
ACPI uses different levels or states of power management. These 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 Microsoft Windows 2000/98/Me ACPI power management states include:
n
LCD timeout — manages power at the lowest level by shutting down the LCD.
n
Standby — also known as Save-to-RAM (STR), Standby manages power by saving your
current working environment to memory and shutting down most system devices.
Conserves more power than an LCD timeout.
n
Hibernate — also known as save-to-disk, or save-to-file (STF) manages power by saving
the current working environment to an area on your hard disk, then powering off your
system. Conserves the most battery power.
