Abstract: A power control apparatus includes a driver for controlling an operation of a storage device, a filter driver for monitoring a state of the storage device, and a management program part for controlling a power supply to the storage device. The management program part is configured to output a control signal based upon the monitored state to a control part operatively connected to the storage device.

Abstract: The present invention relates to an apparatus and a method for managing power in a computer system. A filter driver can be equipped with a packet monitoring function or the like detects whether devices mounted in the computer system are in the idle state. If a device is in the idle state, the power mode of the corresponding device is varied to the power down mode, independent of the system power mode state that has been set up by the operation system in the computer system. In this manner, power supplied to devices in the idle state is reduced, and it becomes possible to have a more efficient control over the load of the computer system. Overall, preferred embodiments according to the present invention can be very advantageously used for developing and expanding the computer system more simply by adding the filter driver into the system, without changing a device driver in the computer system.

Abstract: An apparatus for controlling a power management mode of a multi-core processor in a computer system includes a monitoring unit configured for monitoring conditions relating to the power management mode of the multi-core processor. The apparatus also includes an automatic mode change unit operatively connected to the monitoring unit for receiving the monitored conditions. The automatic mode change unit is configured to set the power management mode of the multi-core processor to a single-core mode or a multi-core mode based on the monitored conditions.

Abstract: Embodiments of an apparatus and method for controlling a power management can reduce power consumption, generate less heat or increase the lifetime of the battery. When the operation mode of the CPU is changed into the deeper sleep mode (C4), an audible noise can be generated by the capacitors of the DC/DC converter, such that the C4 mode has not been used. However, according to embodiments of the invention the C4 mode can be enabled when a prescribed device or prescribed program is detected or when the preset conditions are satisfied.
