Power Management Setup
ACPI Function
If your system supports ACPI, then enable this ACPI function.
ACPI (Advanced Configuration and Power Interface) estab-
lishes industry-standard interfaces for OS-directed configura-
tion and power management on laptops, desktops, and
servers.
ACPI allows the Operating System (instead of the BIOS) to
control Power Management (OSPM). The ACPI Standard
defines hardware registers (which are implemented in chipset
silicon), BIOS interfaces, which include configuration tables,
control methods, and motherboard device enumeration and
configuration; system and device power states, and the APCI
thermal model.
All devices in the system can communicate with each other
about resource use. The operating system has the most
knowledge on a running system's state, and so is in the best
position to perform power management. The choices are:
Enabled / Disabled
