Battery powered electrical equipment such as a portable personal computer operates in one of plural power saving modes to control operating speed and display brightness. The remaining capacity of the battery powering the electrical equipment is derived and one of the power saving modes is selected. The selected power saving mode is automatically displayed in close relationship with the remaining battery capacity so that an operator can readily determine the remaining operating time of the equipment.
