8. The method of claim 1, further comprising:

controlling the electronic apparatus to entering an S3 power-saving state when a battery charging state display period exceeds a preset duration.

9. The method of claim 8, further comprising:

entering a power-off mode when an external power supply is disconnected from the electronic apparatus in the battery charging state display mode or an S3 power-saving state.

10. The method of claim 8, further comprising:

when a second input unit for a power-on mode is selected according to the user input in the battery charging state display mode or the S3 power-saving state,

supplying the power to portions of the components of the electronic apparatus required to operate in the power-on mode; and

performing a second booting operation corresponding to the power-on mode.

11. The method of claim 1, wherein the displaying the battery charging state of the battery includes additionally displaying time information to the battery charging state of the battery.

21. A non-transitory computer-readable medium to contain computer-readable codes as a program to execute the method of claim 1.
