Wake-up and physical button function adjusting method and electronic device using the same

A control method, adapted to an electronic device comprising a physical button having a first function, wherein the physical button is preset with a first key value corresponding to a first function of the electronic device, wherein the first function of the electronic device is executed when the physical button being pressed, the control method comprising:

• detecting a wake-up signal continuously when the electronic device enters a hibernation mode or is in a shutdown state;
• receiving, through an antenna of the electronic device, externally an instruction signal which includes a second key value corresponding to a second function of the electronic device after receiving the wake-up signal through the antenna, and generating an instruction information according to the instruction signal, wherein the instruction information defines the second function, and the second function comprises entering a boot menu or a multi-boot menu of a boot process of the electronic device;
• and
• changing function of the physical button from the first function to the second function by changing key value of the physical button from the first key value to the second key value,
• wherein when the physical button having the second function is pressed, executing the second function to enter the boot menu or the multi-boot menu.

An electronic device, comprising:

• an antenna;
