System power management

The power-management features supported by your system are described in the following sections.

About soft-off

When you turn off your computer by following the Windows shutdown procedure or pressing the power button, a small amount of power (less than 5 watts) still runs to the wakeup circuitry on the system board. In this soft-offstate, your computer can still respond to an incoming signal from the modem or to certain LAN commands.

To remove all power from your computer, turn off the computer and unplug the power cord. When you plug the power cord back in, the network connection LEDs may flash and the fan may start before you press the power button. This is normal.

Using Standby in Windows 98

Windows 98 supports two standards of power management, Advanced Power Management (APM) and Advanced Configuration and Power Interface (ACPI).

The Standby mode, available through both APM and ACPI, saves power by spinning down the hard drive, and by reducing or turning off power to the monitor. ACPI lets your system save additional power in Standby by controlling the power usage of individual devices, add-in boards, and hard drives.

When the system is in Standby, it appears to be off. The computer’s power LED turns amber and the monitor darkens, indicating that the system has entered Standby. However, some wakeup events can bring the system out of Standby.

Important If your system is part of a Novell network, putting your system in Standby disconnects you from your network connection. Reestablish your network connection when you take your system out of Standby.
