摘要： An apparatus and a method for outputting an audio signal of a laptop computer to a first speaker in the laptop computer and a to second speaker in a docking station are provided. The apparatus includes a first controller implemented in the laptop computer for filtering a high frequency band component and a low frequency band component from the audio signal, for mixing the filtered signals, and for outputting the mixed signal to the first speaker when the laptop computer is not coupled with the docking station, and otherwise, filtering only a high frequency band component from the audio signal and outputting the filtered signal to the first speaker. A second controller is implemented in the docking station for receiving the audio signal from the laptop computer, for filtering a low frequency band component from the received audio signal, and for outputting the filtered signal to the second speaker when the laptop computer is coupled with the docking station. When the laptop computer is coupled with the docking station, the audio signal generated in the laptop computer is divided into high and low frequency band signals, and each divided signal is output to different speakers according to the characteristics of the divided signals. Thus, efficiency in use of the speakers and sound quality are improved.

In this computer system, the first parallel port must be installed and the second parallel port must be extended from the portable computer to the expansion device. And between the first and second parallel port, the first and the second peripheral device interconnection recognizing mechanism must be equipped to recognize the type of peripheral device. Also the first and the second power supply must be equipped to cut off or on the power to the peripheral device through the parallel port when the first and the second peripheral device interconnection recognizing mechanism give the recognizing signal. Furthermore the first power supply and the second power supply mechanism doesn't supply power when it recognizes that no peripheral device is connected to the first and second parallel port, or a peripheral device with no need of the power supply is connected. The first and the second power supply mechanism supplies power to a peripheral device through the first and second parallel port when it recognizes that a peripheral device in need of power supply is connected to the first parallel port and the second parallel port.

摘要： A computer system having two fixed disk drives and with a different operating system stored in each disk drive, in which selective booting and suspend/resume operation of the power management can be preformed through the two fixed disk drives. The computer system comprises a first hard disk drive storing a first operating system and a second hard disk drive storing a second operating system, each of the first and second hard disk drive has a reserved data storage area for the suspend operation. A port exchanger intervenes in the master and slave integrated drive electronics (IDE) interface signal lines leading from an integrated drive electronics (IDE) controller to the first and second hard disk drives, in response to a bus exchange control signal fed from a system controller to pass or cross switch the integrated drive electronics (IDE) interface signal paths directed to the first and second hard disk drives. The computer system further includes a controller for producing the bus exchange control signal, under control of the system management part by referring to the first and second hard disk drive status information during booting or resuming process.

摘要： A power supply of a docking system as an extension device of a notebook computer and a power failure safe docking system are disclosed. The power supply of the docking system used as an extension device of the notebook computer includes an AC-to-DC converter receiving an external AC power supply to convert the received AC power supply to a DC power supply, a docking interrupt switch generating a docking interrupt control signal, when no more power is supplied by the AC-to-DC converter or the notebook computer, or it is detected that docking connection of the notebook computer and the docking system is broken, an analog switch receiving power from the AC-to-DC converter, and stopping connection of a peripheral device controller of the notebook computer to one or more extension peripheral devices of the docking system in accordance with the docking interrupt control signal, and a docking power supply control switch cutting off power of the AC-to-DC converter supplied to the one or more extension peripheral devices. Thus, in a docking system having an AC power supply different from a power supply supplied to the notebook computer, even when a power failure occurs or docking of the notebook computer and the docking system is released, the notebook computer or the docking system is not damaged.
