1. A method for saving data of an electronic system in a low temperature environment, wherein the electronic system comprises a first controller and a second controller, the method comprising:

  • the electronic system entering a suspend mode, and moving operation data to a first storage device;

    detecting whether a temperature of the electronic system is lower than a first threshold value, if yes, the first controller storing a flag value as a first constant value;

    the second controller generating an event to notify an application program when the second controller detects that the flag value is the first constant value; and

    the application program triggering the electronic system to enter a hibernation mode according to the event, and moving the operation data to a second storage device.
