3.3 Power Management
Our Rugged Tablet PC series support 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 XP, power supply to
different tablet PC components is controlled on an as-needed basis. This
allows maximum power conservation and performance at the same time.
In general, Windows’ power management works in following state:
