Information processing apparatus and operation control method of an information processing apparatus

1. An information processing apparatus comprising:

an optical disc drive;

a data processing module configured to execute data processing using the optical disc drive; and

a power supply management module configured to manage supply of power to the optical disc drive, wherein:

the data processing module comprises:

an interrogation module configured to interrogate the power supply management module about the optical disc drive at the time of activation; and

a waiting module configured to wait until an operating system recognizes the optical disc drive when an instruction is received from the power supply management module in response to an interrogation by the interrogation module, the instruction instructing to wait until the operating system recognizes the optical disc drive, and

the power supply management module comprises a controller configured to shift the optical disc drive to a power supply on state and to return the instruction to the data processing module, if the optical disc drive is in a power supply off state when the power supply management module receives the interrogation from the data processing module.

2. The apparatus of claim 1 , wherein the waiting module of the data processing module is configured to cause the data processing module to perform normal operation comprising a processing procedure in condition under which the operating system does not recognize the optical disc drive, if a state where the optical disc drive is not recognized continues longer than a predetermined period after the waiting module receives the instruction to wait until the optical disc drive is recognized.

3. The apparatus of claim 2 , wherein the data processing module is configured to determine whether or not the optical disc drive is recognized by issuing a predetermined command to the operating system, the predetermined command being issued repeatedly at predetermined intervals until the optical disc drive is recognized.

4. The apparatus of claim 1 , wherein:

the controller of the power supply management module is configured to return an instruction to perform normal operation to the data processing module when the optical disc drive is in a power supply on state; and

the waiting module of the data processing module is configured to cause the data processing module to perform the normal operation immediately when the second instruction is received from the power supply management module.

5. The apparatus of claim 1 , wherein the controller of the power supply management module is configured to return the instruction to wait until the operating system recognizes the optical disc drive to the data processing module, if the optical disc drive is in a power supply off state when the power supply management module receives the interrogation from the data processing module, subject to satisfaction of a condition that the optical disc drive is physically connected, an item about the optical disc drive in a device manager of the operating system is set validly, and a function of turning on/off power supply to the optical disc drive is supported.

6. The apparatus of claim 5 , wherein the controller of the power supply management module is configured to return the instruction to perform the normal operation comprising the processing procedure in condition under which the operating system does not recognize the optical disc drive to the data processing module, subject to failure of satisfaction of the condition that the optical disc drive is physically connected, an item about the optical disc drive in a device manager of the operating system is set validly, and a function of turning on/off power supply to the optical disc drive is supported.

7. The apparatus of claim 1 , wherein the power supply management module is configured to recognize a state of power supply to the optical disc drive by issuing a predetermined command to a Basic Input/Output System (BIOS).

8. An operation control method of an information processing apparatus comprising an optical disc drive, the method comprising:

causing a data processing module, which executes data processing using the optical disc drive, to interrogate a power supply management module about the optical disc drive at the time of activation, the power supply management module managing supply of power to the optical disc drive;

waiting until an operating system recognizes the optical disc drive when an instruction is received from the power supply management module in response to an interrogation, the instruction instructing to wait until the operating system recognizes the optical disc drive; and

causing the power supply management module to shift the optical disc drive to a power supply on state and return the instruction to the data processing module, if the optical disc drive is in a power supply off state when the interrogation is received from the data processing module.

9. The method of claim 8 , further comprising causing the data processing module to perform normal operation comprising a processing procedure in condition under which the operating system does not recognize the optical disc drive, if a state where the optical disc drive is not recognized continues longer than a predetermined period after the instruction is receive.

10. The method of claim 8 , further comprising:

causing the power supply management module to return an instruction to perform normal operation to the data processing module when the optical disc drive is in a power supply on state; and

causing the data processing module to perform the normal operation immediately when the second instruction is received from the power supply management module.
