NEC VX manual Recognizing the Windows 98 Power Management States

Windows 98 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 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.

Recognizing the Windows 98 Power Management States

It is important to recognize your system’s behavior when in each of these power management states. The following table describes the system behavior for each power management state.
