Referring to FIG. 2, a flow chart of a method for safely replacing a battery of an electronic device in accordance with an embodiment of the present invention is shown. The method of safely replacing the battery of the present example is applied, for example, to the electronic device 100 described above in accordance with an embodiment of the present invention. First, as shown in step S1, the electronic device 100 is provided. In the electronic device 100, the first battery 120 is housed in the battery well 110a, and the battery cover 130 is coupled to the housing 110 and covers the battery compartment 110a. Next, in step S2, when the battery cover 130 moves away from the housing 110, the electronic device 100 is switched from the higher power usage mode to the lower power sleep mode. The user can selectively perform a freezing step before step S2. In practical applications, when the user presses the button 113 on the casing 110 to press the function key 145, the freezing unit 143 stops the reading, calculation, and writing of the data, and suspends the program being executed. In one embodiment, step S2 includes the step of storing the operational state of the freeze to enter the sleep mode. Next, as shown in step S3, when the first battery 120 moves away from the battery bay 110a, the electronic device 100 is switched from the first battery powered mode to the second battery powered mode. As shown in step S4, when the first battery 120 is placed in the battery slot 110a, the electronic device 1 is switched to the first battery power supply mode to complete the action of replacing the first battery 120. In this step, the user can place another 201118541 fully charged and identical first battery. Next, as shown in step S5, when the battery cover 130 is attached to the casing 110 and covers the battery compartment 110a, the electronic device 100 is switched to the usage mode. In addition, in an embodiment, the user can press the function key 145 by pressing the button 113 on the housing 110. By stopping the operation state of the electronic device 100, the electronic device 100 resumes the data reading, calculation, and writing operations at the time of freezing, and resumes the execution of the program. In this manner, the electronic device 100 can allow the user to continue using the electronic device 100 in a short period of time without waiting for a lengthy boot time. In the above electronic device according to the example of the present invention and the method of safely replacing the battery, when the user opens the first battery cover and removes the battery, the electronic device is in a low power sleep state and is in the second battery power supply mode. As a result, the work and storage information being processed in the electronic device will not be lost due to power failure. In addition, when the first battery is repositioned in the battery compartment and the battery cover is returned, the electronic device can quickly return to the use state. This saves the lengthy boot time, greatly shortens the time the user waits, and improves the efficiency of use. The present invention has been disclosed in the above embodiments, and is not intended to limit the present invention, and the present invention can be variously modified and retouched without departing from the spirit and scope of the present invention.
