Abstract

A computer including a main body in which a system is built, a peripheral device coupled to the main body, a power supplying part to supply power to the system and/or the peripheral device, an interface part to communicate with an external device, and a controller to control the power supplying part to apply power to the system but not to the peripheral device if a power-saving power applying signal is received through the interface part.

Claims

1. A computer comprising:

a main body in which a system is built;

a peripheral device coupled to the main body;

a power supplying part to supply power to the system or to the system and the peripheral device;

an interface part to communicate with an external device; and

a controller to control the power supplying part to apply power to the system but not to the peripheral device if a power-saving power applying signal is received through the interface part.

2. The computer according to claim 1, wherein the power supplying part comprises a switching part to define a path along which power is applied to the peripheral device.

3. The computer according to claim 2, wherein the controller controls the switching part to prevent power from being applied to the peripheral device if the power-saving applying signal is received through the interface part.

4. The computer according to claim 3, wherein the switching part comprises a switch that corresponds to the peripheral device.

5. The computer according to claim 4, wherein the controller controls the switch to prevent the power from being applied to the peripheral device if the power-saving applying signal is received through the interface part.

6. The computer according to claim 1, wherein the peripheral device is plural in number and wherein the power-saving applying signal includes selection information to select that only certain peripheral devices are not to have power applied thereto.

7. The computer according to claim 6, wherein the certain peripheral devices corresponding to the selection information are prevented from receiving power.

8. A remote control system, comprising:

a client computer to apply power only to a system therein without applying power to a peripheral device coupled thereto if a power-saving applying signal is received by the client computer; and

a host computer, connected with the client computer through a network, to transmit the power-saving applying signal to the client computer.

9. The remote control system according to claim 8, wherein the peripheral device of the client computer is plural in number and the host computer further transmits selection information to select that certain peripheral devices are not to have power applied thereto.

10. The remote control system according to claim 9, wherein the client computer prevents power from being applied to the certain peripheral devices corresponding to the selection information.

11. A method of controlling a computer including a main body and a peripheral device, comprising:

determining whether a power applying signal for applying power to the main body and the peripheral device is a power-saving applying signal; and

blocking power from being applied to the peripheral device when the power applying signal is determined to be the power-saving applying signal.

12. The computer control method according to claim 11, wherein the determining comprises determining whether selection information to select a blocking of power to the peripheral device is present within the power-saving applying signal;

and

blocking the power applied to the peripheral device.

13. A method of remotely controlling a client computer via a host computer, comprising:

transmitting either a power applying signal or a power-saving applying signal to the client computer from the host computer; and

blocking power from being applied to a peripheral device of the client computer when the power-saving applying signal is transmitted to the client computer.

14. The remote control method according to claim 13, further comprising:

generating selection information to select the peripheral device to be blocked from the power supply when the host computer applies the power to the client computer; and

blocking the power applied to the peripheral device selected according to the selection information.

15. A computer network including a host computer and a client computer, the client computer comprising:

a system to conduct operations according to an operating system (OS);

a peripheral device coupled to the system;

a power supplying part to supply power to the system or to the system and the peripheral device according to a type of a power supplying signal transmitted from the host computer;

a controller to determine the type of the power supplying signal; and

a switching part to prevent power from being applied to the peripheral device if the type of the power supplying signal indicates that the peripheral device is to be prevented from receiving power.

16. The computer network according to claim 15, wherein the switching part prevents power from being applied to the peripheral device when the power supplying signal is determined to be a power-saving supplying signal.

17. The computer network according to claim 15, further comprising an interface part to receive the power supplying signal from the host computer.

18. The computer network according to claim 15, wherein the peripheral device is plural in number.

19. The computer network according to claim 18, wherein the switching part prevents power from being applied to the peripheral devices when the power supplying signal is determined to be a power-saving supplying signal.

20. The computer network according to claim 18, wherein the switching part prevents power from being applied to certain ones of the peripheral devices when the power supplying signal is determined to be a power-saving supplying signal including selection information that indicates that only the certain peripheral devices are to be prevented from having power applied thereto.

21. The computer network according to claim 15, wherein the client computer is plural in number.

22. The computer network according to claim 21, wherein the peripheral device of each client computer is plural in number.

23. The computer network according to claim 22, wherein the switching parts of each client computer prevent power from being applied to the peripheral devices of each client computer when the power supplying signal is determined to be a power-saving supplying signal.

24. The computer network according to claim 22, wherein the switching parts of each client computer prevent power from being applied to certain peripheral devices of each client computer when the power supplying signal is determined to be a power-saving supplying signal including selection information that indicates that only the certain peripheral devices are to be prevented from having power applied thereto.

25. The computer network according to claim 24, wherein the certain peripheral devices comprise all of the peripheral devices of each of the client computers, corresponding peripheral devices of the client computers, differing peripheral devices of the client computers, and/or combinations thereof.
