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