POWER SAVING CONTROL METHOD AND DEVICE IN ELECTRONIC DEVICE, AND POWER SAVING ELECTRONIC DEVICE

摘要

A power saving control method includes providing a latch circuit that is supplied with current for operation from a power source even if a switch circuit is turned off, so that the switch circuit is controlled to be turned off when the latch circuit is in a latched state and turned on when the latch circuit is in an unlatched state, operating an automatic-reset operation switch so that a power off process in the main load circuit is performed and the latch circuit is turned into the latched state for turning off the switch circuit when the switch circuit is in the ON state, and operating the automatic-reset operation switch so that the latch circuit is turned into the unlatched state for turning on the switch circuit when the switch circuit is in the OFF state.
