  • Integrated driver electronic (IDE) device power control
    Patent number: 6857079
    Abstract: Methods and apparatus for power managing IDE devices. A driver is coupled to a switch, the driver receiving a control signal from a computer system, the control signal indicating whether the computer system is in a power-save mode. The driver drives the switch which generates an output control signal to an IDE device. When the operating system detects that the computer system has been idle for a certain period of time, the operating system toggles the control signal that feeds into the driver which shuts off the switch so that power feeding to the IDE device is shut off.
