1. An electronic apparatus having a plurality of operation modes, the electronic apparatus comprising:
- an input circuit configured to receive an input of DC power from an external adaptor;
a battery configured to store the received DC power, the battery removable from the electronic apparatus;
a first controller configured to use selectively provided power to operate the electronic apparatus in a first operation mode using power of only the battery or power of only the input circuit, and to use the selectively provided power to operate the electronic apparatus in a second operation mode using both the power of the battery and the power input from the input circuit simultaneously;
a power controller configured to selectively provide the power input through the input circuit and the battery to the first controller and to prevent an operating mode of the electronic apparatus from being changed from the first operation mode to the second operation mode according to a detected charge state of the mounted battery being less than or equal to a predetermined capacity and according to a supply of the DC power received by the input circuit, and upon detecting the battery is not mounted in the electronic apparatus; and
a display to display an alert message when a mode of the electronic apparatus is changed to the second operation mode and the second operation mode is maintained longer than a predetermined time,wherein the first controller using the selectively provided power comprises at least one of a central processing unit (CPU), a graphic processor, and a CPU having a graphic processor embedded therein.

10. A driving control method of an electronic apparatus which has a plurality of operation modes, the method comprising:
-
selectively providing power to a controller to operate the electronic apparatus in a first operation mode according to a predetermined first thermal design power; and changing an operation mode of the electronic apparatus to a second operation mode, in which the controller selectively provides power to the controller to operate the electronic apparatus according to a second thermal design power higher than the first thermal design power, using both a DC power provided from an external adaptor and a power of a battery simultaneously according to an operation load of the electronic apparatus, the battery removable from the electronic apparatus; and displaying an alert message when a mode of the electronic apparatus is changed to the second operation mode and the second operation mode is maintained longer than a predetermined time, wherein the changing comprises preventing the operation mode of the electronic apparatus from being changed from the first operation mode to the second operation mode according to a detected charge state of the mounted battery being less than or equal to a predetermined capacity and according to a supply of the DC power provided from the external adaptor, and upon detecting the battery is not mounted in the electronic apparatus, and wherein the controller using the selectively provided power comprises at least one of a central processing unit (CPU), a graphic processor, and a CPU having a graphic processor embedded therein. - View Dependent Claims (11, 12, 13)

14. A non-transitory computer-readable medium including computer-readable codes as program to execute a driving control method in an electronic apparatus which has a plurality of operation modes, the driving control method of an electronic apparatus which has a plurality of operation modes comprising:
-
selectively providing power to a controller to operate the electronic apparatus in a first operation mode according to a predetermined first thermal design power; changing an operation mode of the electronic apparatus to a second operation mode, in which the controller selectively provides power to the controller to operate the electronic apparatus according to a second thermal design power higher than the first thermal design power, using both a DC power provided from an external adaptor and a power of a battery simultaneously according to an operation load of the electronic apparatus, the battery removable from the electronic apparatus; displaying an alert message when a mode of the electronic apparatus is changed to the second operation mode and the second operation mode is maintained longer than a predetermined time, wherein the changing comprises preventing the operation mode of the electronic apparatus from being changed from the first operation mode to the second operation mode according to a detected charge state of the mounted battery being less than or equal to a predetermined capacity and according to a supply of the DC power provided from the external adaptor, and upon detecting the battery is not mounted in the electronic apparatus and according to a supply of the DC power provided from the external adaptor, and wherein the controller using the selectively provided power comprises at least one of a central processing unit (CPU), a graphic processor, and a CPU having a graphic processor embedded therein.
