Power control device, method, and terminal device

A terminal device, comprising a power control device, wherein the power control device comprises a modem, a first power management module connected to the modem, an application processor (AP), and a second power management module connected to the AP, and the terminal device further comprises:

• a processor, a memory, and a computer program stored in the memory and executable on the processor;
• the computer program, when executed by the processor, causes the power control device to perform:
• generating a first control signal in a case that the AP receives a shutdown instruction or an abnormal power-down is detected;
• converting, under control of the first control signal, a second control signal into a third control signal, wherein the second control signal is a signal output by the second power management module to the first power management module before the AP receives a shutdown instruction or an abnormal power-down is detected;
• stopping power supply to the modem under control of the third control signal.

A non-transitory computer-readable storage medium, applied to a terminal device, wherein the terminal device comprises a power control device, and the power control device comprises a modem, a first power management module connected to the modem, an application processor (AP), and a second power management module connected to the AP;

• the non-transitory computer-readable storage medium stores a computer program, and the computer program, when executed by a processor of the terminal device, causes the power control device to perform:
• generating a first control signal in a case that the AP receives a shutdown instruction or an abnormal power-down is detected;
• converting, under control of the first control signal, a second control signal into a third control signal, wherein the second control signal is a signal output by the second power management module to the first power management module before the AP receives a shutdown instruction or an abnormal power-down is detected;
• stopping power supply to the modem under control of the third control signal.
