1. A method for booting a computer device under a low temperature state, comprising:

  • detecting a trigger signal to determine whether a power button of the computer device is pressed;

    obtaining a hard disk temperature via a second temperature sensor of a hard disk of the computer device, if the power button is pressed;

    determining whether the hard disk temperature is less than a first predetermined temperature;

    if the hard disk temperature is less than the first predetermined temperature, activating a heater of the hard disk to heat the hard disk;

    determining whether the hard disk temperature is greater than a first predetermined temperature via the second temperature sensor;

    if the hard disk temperature is greater than the first predetermined temperature, turning the heater off and determining whether a voltage of a battery cell of the computer device reached a predetermined voltage;

    if voltage of a battery cell of the computer device has reached a predetermined voltage, activating a system component of the computer device;

    if the hard disk temperature is less than the first predetermined temperature, obtaining a battery temperature of the battery cell via a first temperature sensor of the computer device; and

    determining whether the battery temperature is less than a second predetermined temperature.
