[0003] When using these portable electronic devices, it is necessary to use a battery to supply the power required for operation. The currently widely used battery relies on a general commercial AC power source. When the rechargeable battery is exhausted, it cannot be charged without the mains AC power. In order to make the use of the portable electronic device longer, it has appeared that the rechargeable battery of the portable electronic device is charged by the solar power as an auxiliary power source. [0004] However, in the power management system using solar power as the auxiliary power source, even if the solar power and the rechargeable battery are exhausted, even if the solar power is generated again, the system cannot be automatically turned on and switched to the solar power because the system is in the off state. To supply power to electronic devices, the user must use the commercial AC power to charge the rechargeable battery, and the solar auxiliary power can be used normally after the electronic device is turned on. Therefore, the existing application of a power management system using solar energy as an auxiliary power source has certain limitations.
