Abstract
A method of operating a portable computing device in a first mode uses a rechargeable energy source while transferring data between the portable computing device and a computer network in response to user actions. The portable computing device is operated in a second mode using a non-rechargeable energy source while transferring data between the portable computing device and the computer network free from user actions. The portable computing device automatically changes from the first mode to the second mode in response to engaging the portable computing device with a stand supporting the portable computing device and providing the non-rechargeable source.
