An offline setup recording device used in an electronic apparatus is illustrated. When the electronic apparatus is power on, the total energy storage unit is charged by a power supply through the unidirectional conduction unit, such that a total voltage is stored therein. When the electronic apparatus is power off, a user operates the automatically recovering switch to be conducted, such that the state energy storage unit is charged by the total energy storage through the automatically recovering switch, and a storage voltage signal is stored therein. When the electronic apparatus is power on again, the reading unit receives the power, reads out the storage voltage signal, and outputs a read voltage signal accordingly.
