Method for controlling operation of optical disk drive in power saving mode

A computer system, comprising:

• a central processing unit controlling overall operation of said computer system;
• a control unit generating a power saving control signal when said computer system is inactive for a predetermined time period;
• a hard disk drive storing first data;
• an audio chip processing audio data in accordance with said central processing unit;
• an optical disk drive selectively receiving a disk storing second data;
• said central processing unit performing a power-on self-test operation when said computer system is first powered on, to set interrupt request values and input/output addresses of said hard disk drive and said audio chip to correspond to system activities and to not set an interrupt request value and input/output addresses of said optical disk drive to correspond to system activities:
• said central processing unit performing an operating system routine on said computer system to finish a boot-up process after said setting of said interrupt request values is performed, when said computer system is first powered on;
• and
• said central processing unit responding to said power saving control signal to determine when said optical disk drive is in operation, setting first predetermined components of said computer system including said optical disk drive to a power saving mode when said optical disk drive is not in operation, and setting second predetermined components of said computer system not including said optical disk drive to said power saving mode when said optical disk drive is in operation.

A method for controlling operation of an optical disk drive in a computer system including a hard disk drive, an audio chip, and a control unit, comprising:

• performing a power-on self-test operation when said computer system is first powered on, to set interrupt request values and input/output addresses of said hard disk drive and said audio chip to correspond to system activities, and to not set an interrupt request value and input/output addresses of said optical disk drive to correspond to system activities;
• performing an operating system routine on said computer system to finish a boot-up process after said setting of said interrupt request values is performed, when said computer system is first powered on;
• generating a power saving control signal, at said control unit, when said computer system is inactive for a predetermined time period;
• determining whether said optical disk drive is in operation, when said power saving control signal is generated;
• and
• setting predetermined components of said computer system not including said optical disk drive and not including related optical disk drive components to said power saving mode, when said optical disk drive is in operation.
