3.4 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:
