Fig. 1 is a flowchart illustrating a power management method of a terminal device according to an exemplary embodiment, the power management method of the terminal device being applied to a micro control unit in the terminal device. As shown in FIG. 1, the method includes the following steps S11-S14:
in step S11, when the access of the power adapter is detected, a first instruction is sent to the battery charging circuit of the terminal device to manage the charging parameters of the terminal device.
In step S12, when the shutdown command is received, a second command is sent to the power management circuit of the terminal device to cause the power management circuit to stop supplying power to the power consumption system of the terminal device.
