Abstract:
1. An information processing apparatus, comprising: a connector that conforms to a Universal Serial Bus standard, the connector including first and second signal terminals; a charger circuit operable to receive power supplied from a charger that is connected via the connector, and to charge one or more devices within the information processing apparatus; a detector that detects voltages at the first and second signal terminals of the connector a plurality of times and repeats such detection of the voltages at regular intervals while charging is performed by the charger circuit; and a judgment section that judges a type of an apparatus connected to the connector by analyzing the voltages at the first and second signal terminals obtained the plurality of times, and that controls the charger circuit to stop charging if it is judged that the apparatus connected via the connector has been changed from the charger to another apparatus, wherein the charger circuit stops sending power supply requests to the connected apparatus if it is judged that the apparatus connected via the connector has been changed from the charger to the another apparatus.
