The present invention relates to an electronic apparatus which is arranged to drive a load by means of a microcomputer to which the boosted voltage obtained by boosting a battery output by boosting means is applied. The present invention also relates to a method of making the boosting means inoperative upon completion of a load-driving operation by the computer after the battery output is restored to a predetermined level, and switching the voltage to be applied to the microcomputer in the electronic apparatus from the boosted output to the battery output, thereby preventing the microcomputer from malfunctioning due to a lowering in the battery output.
