Abstract
An electronic apparatus according to the invention can be powered by a fuel cell unit and secondary battery unit. Power supply management utility executed by a CPU displays the states of use of the fuel cell unit and secondary battery unit. If a predetermined operation is performed in response to the displayed states, using a pointing device, the power supply management utility permits various types of setting related to the use of the fuel cell unit and secondary battery unit to be performed.
