Power Management Features

The system comes with Advanced Power Management (APM) and Advanced Configuration and Power Interface (ACPI). Included as a subset to ACPI is Instantly Available Technology.

APM features Soft Power Off, which automatically powers down the system when exiting Windows 98 or Windows 2000 (not available for Windows NT). This feature is enabled or disabled through the system’s BIOS (see Section 2, “System Configuration,” for Power Management BIOS settings).

Instantly Available Technology features the ACPI sleep mode which maximizes power savings. When in the sleep mode, the system appears to be off. The power supply and fans are off and the power lamp is amber. Pressing a key or moving the mouse instantly wakes up the system and returns it to where it was before going into the sleep mode. This feature is enabled or disabled by setting jumpers on the system board (see Section 2, “System Configuration” for information on setting system board jumpers).

If the system has an optional internal or external modem installed, the Wake On Ring (WOR) and Resume On Ring (ROR) features of the system can be used. With WOR, the system can be powered up through the modem from either the Soft Power Off or ACPI modes. The first call through the modem powers on the system and the second call allows access to your system.

The ROR feature allows a single call on the modem to resume system operation and to allow system access. The ROR feature can be used while the system is in the sleep mode or the ACPI power on state.

See Section 2, “System Configuration” for information on setting the WOR and ROR features through the system’s BIOS. In addition, for the WOR feature, a cable must be connected to a modem and to the WOR connector on the system board.
