1.11.1 ACPI
ACPI gives the operating system direct control over the power management and Plug and Play
functions of a computer. The use of ACPI with this Compute Stick requires an operating system
that provides full ACPI support. ACPI features include:
• Plug and Play (including bus and device enumeration)
• Power management control of individual devices
• A Soft-off feature that enables the operating system to power-off the computer
• Support for multiple wake-up events (see Table 5 on page 16)
Table 3 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.
