I just received my CoreS3. The documentation and the device's box mentioned a 500 mAh internal battery. However, I am unable to 1) find the battery in the device and 2) launch the device without it being plugged in.

Going into the power tab of the demo software, I see 0.0V for the battery... Which to me would indicate the absence of a battery.

Since the documentation mentions the internal battery, I assume I have a defective unit that was shipped without it or am I mistaken?
