Windows NT Power Management States
APM uses different levels or states of power management. These power management
states occur automatically, based on your 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 your 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 your hard disk, then powering
off your system. Conserves the most battery power.
