1. a kind of terminal device, comprising:

  • Adapter input terminal configures to receive the input power from power supply adaptor;

    Cell input terminal configures to receive the input power from battery;

    System power supply output end, configuration to provide internal electric source to the system hardware module of the terminal device;

    First switch unit is arranged between the adapter input terminal and the system power supply output end;

    Second switch unit is arranged between the cell input terminal and the system power supply output end;

    Event trigger circuit configures to be based on preset incoming event signal, controls the first switch unit and described theThe conduction and cut-off of two switch units, wherein the event trigger circuit can be generated based on the preset incoming event signalCorresponding flag information, and the event trigger circuit is triggering latch cicuit;

    AndMicrocontroller configures to control the event trigger circuit, wherein the microcontroller is controlled based on the flag informationThe event trigger circuit, whereinThe incoming event signal is that battery accesses signal, and the battery access signal is to be inserted into the terminal in battery to setThe voltage transitions that the cell input terminal generates when standby upper, and event trigger circuit generation is corresponding with battery access signalIdentification information;

    The event trigger circuit opens the first switch unit and described second when detecting the battery access signalUnit conducting is closed, to power to the microcontroller;

    The microcontroller obtains identification information corresponding with battery access signal from the event trigger circuit, is based on the markKnow information and judges whether the adapter of terminal device accesses.
