A method for entering an operation mode in a low-temperature environment is applicable in a situation that plural electronic devices (900a, 900b) in an electronic apparatus (800) are not activated. Through performing the method, the electronic apparatus (800) obtains a temperature (Td1, Td2) of each electronic device (900a, 900b) after receiving a request of a user. Then the electronic apparatus (800) determines whether the temperatures (Td1, Td2) of all the electronic devices (900a, 900b) reach a threshold value. If the temperatures of at least two electronic devices (900a, 900b) do not reach the threshold value, the electronic apparatus (800) generates a plurality of corresponding enable signals for the electronic devices (900a, 900b) having the temperatures (Td1, Td2) lower than the threshold value. The waveforms of the enable signals (PWM1, PWM2) vary alternately. The electronic apparatus (800) transfers the enable signals to a plurality of corresponding heaters (120a, 120b). Being activated by the received enable signal (PWM1, PWM2), each of the heaters (120a, 120b) heats the corresponding electronic device (900a, 900b). |
