Windows NT Power Management States

APM 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 configured to occur while on battery power or on AC power.
The Windows NT APM power management states include:
Standby — manages power at the lowest level by shutting down the LCD, hard disk drive,
!
and CPU.
Suspend — also known as Save-to-RAM (STR), Suspend mode manages power by saving
!
the current working environment to memory and shutting down most system devices.
Conserves more power than Standby mode.
Save-to-file (STF) — also known as save-to-disk, STF mode 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.
