Windows 98 Power Management States; Recognizing The Power Management States - NEC VERSA FX Manual

Windows 98 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 Windows 98 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
!
your 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 your hard disk, then powering
off your system. Conserves the most battery power.
