ABSTRACT:
A method for controlling operation of an optical disk drive in a computer having the optical disk drive, a hard disk drive and a power management controller. The power management controller generates a power saving control signal when the computer system is suspended in use for a predetermined time period. If the power saving control signal is generated, a central processing unit (CPU) determines whether the optical disk drive is in operation in order to block the power supplied to either all components of the computer system or the components of the computer system except for the optical disk drive. That is, if the optical disk drive is not in operation, power is blocked to all components of the computer system. If the optical disk drive is in operation, however, power is blocked to components of the computer system except the optical disk drive and its associated components.
