Power Management
Your computer supports ACPI (Advanced Configuration and Power
Interface) for power management. The power management feature allows
you to reduce the power consumption for energy saving.
With an ACPI-compliant operating system such as Windows, power
supply to different computer components is controlled on an as-needed
basis. This allows maximum power conservation and performance at the
same time.
