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.
Windows comes with pre-defined power plans (Balanced, Power Saver, and
High Performance) for you to select. By default, your computer is in
Balanced mode which works in this way:
