Abstract
A peripheral device for a computer is powered by an internal rechargeable battery. A data line electrically connects the peripheral device to the computer. The data line has conductors that provide for data transmission between the computer and the peripheral device. The data line also has conductors that provide for power transmission from the computer to the peripheral device. The peripheral device uses the power transmission conductors to recharge the battery, thereby eliminating the need for a separate power line to be associated with the peripheral device.
