Product Description

Table 5 lists the system states based on how long the power switch is pressed,

depending on how ACPI is configured with an ACPI-aware operating system.

Table 5. Effects of Pressing the Power Switch

If the system is in this

state…

…and the power switch is

pressed for

…the system enters this state

System States and Power States

Under ACPI, the operating system directs all system and device power state

transitions. The operating system puts devices in and out of low-power states based

on user preferences and knowledge of how devices are being used by applications.

Devices that are not being used can be turned off. The operating system uses

information from applications and user settings to put the system as a whole into a

low-power state.
