Motion Sensor
The terminal hardware can detect movement near the terminal and
enables software to prompt system operation from a low-power state.
Application software may also be able to make use of motion detection
when in the ON state if it is enabled by lower-level software.

Camera
Motion is detected as a change in ambient light level that is greater
than a software-controlled threshold.
A photodiode mounted behind the front bezel of the unit senses
ambient light levels. The photodiode resides on a small circuit board
(the Motion Sensor Board). A harness connects the Motion Sensor
Board to the amplifier and motion sensing logic on the Processor
Board. The user Power/Status LED indicator shares this board.
Power/Status LED
The LED power indicator indicates that power is present. The LED is
green when the processor and BIOS are operating properly. The LED is
mounted behind the front bezel on the same board as the motion
sensor.
