Description of the Invention (1) [Preface] This case is a power supply method for a backup power supply system that automatically wakes up electrical appliances in response to a resumption of power. When a power outage occurs, the appliance automatically enters the power saving mode, and at the end of the power outage, the appliance automatically wakes up from the power saving mode and returns to a normal operation mode. [Conventional Technology] The rapid development of computer technology ’is constantly updated in hardware or software. In the waves of reforms, the computer functions have increased, which has also brought about improvements in peripheral equipment, such as the continuous power supply backup system. In order to improve the reliability of the computer (rel iabi 1 i ty) and stability (stabi 1 i ty), a redundant power system has appeared. Early backup power supply systems mostly referred to uninterruptible power supply systems (UPS). This type of system can enable the computer to maintain a long period of work, such as two hours, when the mains power is interrupted. This is only suitable for large-scale laboratories or server computer systems that need to keep the system uninterrupted. For ordinary PC users, this kind of UPS is not economical or practical. Users of personal computers do not continue to work when the power supply is interrupted, but when the power is cut off, the data of the personal computer may be lost or damaged. Therefore, the computer can save the data to the computer in time when the power is cut. The backup power supply system of hard disks is gradually at the beginning of the road in the city's Yanglu Arm mα ★ μ society. This kind of redundant power supply system is available for several minutes, allowing users of the computer to perform the actions of turning off the power & the money in time.
