Power Management
The Mobile Board supports the latest version of the Advanced Configuration and Power
Interface (ACPI) specification.
ACPI gives the operating system direct control over the power management and Plug
and Play functions of a computer. The use of ACPI with the board requires an
operating system that provides full ACPI support such as Microsoft Windows Vista.
ACPI features include:
• Plug and Play (including bus and device enumeration)
• Power management control of individual devices, add-in cards (some add-in cards
may require an ACPI-aware driver), and hard disk drives
• A soft-off feature that enables the operating system to power-off the computer
• Support for multiple wake-up events (see Table 12 and Table 13)
• Support
for a sleep/hibernate mode switch
ACPI gives the operating system direct control over the power management and Plug
and Play functions of a computer. The use of ACPI with the Mobile Board requires an
operating system that provides full ACPI support.
