Power management modes

Sleep mode

Power management functions are handled by the ACPI-aware operating system. In this set-up, you do not need to set timeout values for devices before they enter a power saving mode.

Sleep mode may be one of three computer power saving modes: standby, hibernation or power off. Windows determines which of these modes to enter in.

To enter Sleep mode:

•Press the Sleep hot key Fn-F4.

•Idle times for devices and the computer determined by Windows 98 elapses

Exiting sleep mode depends on which power saving mode the computer is currently in.

Standby mode

The computer consumes very low power in Standby mode. Data remains intact in the system memory until the battery is drained.

There are a number of ways to enter Standby mode:

•If the waiting time specified by the System Standby value or the operating system elapses without any system activity

•Closing the display cover

•When the computer is about to enter Hibernation mode (e.g., during a battery- low condition), but the Hibernation file is invalid or not present

•When customized functions for power management are set to Standby and the corresponding action is taken. See “Setting advanced features in power management” on page 86 for more information.

•Invoked by the operating system power-saving modes

Note: If your computer is running Windows NT 4.0 or Windows 95, Fn-F4acts as the standby hot key.

The following signals indicate that the computer is in Standby mode:

•The buzzer beeps

•The Sleep indicator lights
