INFORMATION AND COMMUNICATION TECHNOLOGIES AIMING AT THE REDUCTION OF THEIR OWN ENERGY USE ## Abstract A computer system. The computer system includes a communication unit to receive power to perform communication with an external apparatus; and a controller to check whether at least one program to make the communication unit perform the communication is executing, and controls the communication unit to decrease consumption of power by the communication unit if the executing program is not a pre-set program. ## Claims ### Claim 1 A computer system comprising: a communication unit to receive power to perform communication with an external apparatus; and a controller to check whether at least one program to make the communication unit perform the communication is executing, and to control the communication unit to decrease consumption of power by the communication unit if the executing program is not a pre-set program. ### Claim 2 (depends on 1) The computer system according to claim 1, wherein the controller decreases the consumption of the power by shutting off a supply of power to the communication unit. ### Claim 3 (depends on 1) The computer system according to claim 1, wherein the controller decreases the consumption of the operating electric power by controlling the communication unit to stop the communication. ### Claim 4 (depends on 1) The computer system according to claim 1, further comprising: a user input unit to receives a user's command with regard to setting the pre-set program; and wherein the controller determines whether the executing program is the pre-set program according to the user's command. ### Claim 5 (depends on 4) The computer system according to claim 4 further comprising: a displaying unit to display a graphical user interface (GUI) with regard to the setting of the program; wherein the controller controls the displaying unit to display at least one item corresponding to at least one program and a select box to select one of the at least one programs according to the user's command on the GUI. ### Claim 6 (depends on 1) The computer system according to claim 1, further comprising: a battery unit to supply the power to the communication unit. ### Claim 7 (depends on 1) The computer system according to claim 1, wherein the controller controls the communication unit to decrease the consumption of the power by the communication unit if the at least one program is not executing. ### Claim 8 A control method of a computer system comprising a communication unit to receives power to perform communication with an external apparatus, the control method comprising: checking whether at least one program to make the communication unit perform the communication is executing based on a pre-set program; and controlling the communication unit to decrease consumption of the power by the communication unit if the executing program is not the pre-set program. ### Claim 9 (depends on 8) The control method of the computer system according to claim 8, wherein the controlling of the communication unit comprises decreasing the consumption of the power by shutting off a supply of power to the communication unit. ### Claim 10 (depends on 8) The control method of the computer system according to claim 8, wherein the controlling of the communication unit comprises decreasing the consumption of the power by controlling the communication unit to stop communication. ### Claim 11 (depends on 8) The control method of the computer system according to claim 8, further comprising determining whether the executing program is the pre-set program by receiving a user's command with regard to setting the pre-set program. ### Claim 12 (depends on 11) The control method of the computer system according to claim 11, wherein the determining of the pre-set program comprises: displaying a graphical user interface (GUI) having at least one item corresponding to at least one program and a select box to select one of the at least one program the program as the pre-set program according to the user's command. ### Claim 13 (depends on 8) The control method of the computer system according to claim 8, further comprising: supplying the power to the communication unit via a battery unit. ### Claim 14 (depends on 8) The control method of the computer system according to claim 8, wherein the controlling of the communication unit comprises controlling the communication unit to decrease the consumption of the power by the communication unit if the at least one program is not executing. ### Claim 15 A computer system comprising: a communication unit to receive an power to perform communication with an external apparatus; and a controller to check whether at least one web page is transmitted according to the communication performed by the communication unit, and to control the communication unit to decrease consumption of the power by the communication unit if the transmitted web page is not a pre-set web page. ### Claim 16 A control method of a computer system comprising a communication unit to receive power to perform communication with an external apparatus, the control method comprising: checking whether at least one web page is transmitted according to a communication performed by the communication unit based on a pre-set web page; and controlling the communication unit to decrease consumption of the power by the communication unit if the transmitted web page is not the pre-set web page. ### Claim 17 A computer comprising: a communication unit to communicate with an external apparatus via a network; and a control unit to determine whether operation of the communication unit is necessary and to control the communication unit to operate normally or to operate at decreased power consumption depending on the result of the determination. ### Claim 18 (depends on 17) The computer of claim 17, wherein the control unit determines whether operation of the communication unit is necessary based on whether a pre-set communication program is executing and/or a pre-set web page is being accessed. ### Claim 19 A method of controlling power consumption of a communication unit, the method comprising: determining if a pre-set communication program is executing and/or a pre-set web page is being accessed; and decreasing the supply of power to a communication unit if the pre-set communication program is not executing or the pre-set web page is not being accessed. ### Claim 20 (depends on 19) The method of claim 19, wherein the decreasing of the supply of power comprises shutting off the supply of power to the communication unit. ### Claim 21 (depends on 19) The method of claim 19, wherein the decreasing of the supply of power comprises: terminating any programs currently executing that are not the pre-set communication program; and terminating the access of any web page that is not the pre-set web page.
