Abstract: An auto turn-on module at least includes a timer, a logic unit and a memory unit. The timer provides real time data. The logic unit is electronically connected with the timer and has a register, wherein the register stores a state indicator data therein. The memory unit is electronically connected with the logic unit and stores therein a turn-on schedule data. If the real time data and the turn-on schedule data are the same after being compared, a turn-on signal is generated from the logic unit, and the state indicator data stored in the register is changed according to the turn-on schedule data.
