A power supply facility includes a primary power circuit coupled to energize a CPU, a control circuit coupled to the CPU, and an auxiliary power circuit coupled to the control circuit for supplying electric power to the CPU via the control circuit. A detecting device nay detect the power supply to the CPU, and may actuate the control circuit to couple the auxiliary power circuit to energize the CPU when the primary power circuit is unable to energize the CPU, or when the electric power supplied to the CPU is cut off, or when the power supply is less then the required value.
