According to the present invention, a computer is provided, which comprises a host system, an embedded subsystem, a power source, an input device control module, a first transmission interface and a second transmission interface, the input device control module being connected to the embedded subsystem through the first transmission interface, wherein the input device control module is configured to establish, in response to receipt of a first switching instruction, communication with the embedded subsystem such that the embedded subsystem is enabled to process input data from an input device and to transmit the input data obtained from the input device to the first transmission interface; and the embedded subsystem is configured to receive the input data from the first transmission interface, process the input data and perform an operation corresponding to the input data. According to the present invention, one set of input devices can be shared between a computer and an embedded system through design and modification in software without any change in the existing hardware design for the computer.

Computer and method for sharing input device thereof

A data output method and apparatus according to the present invention, which are applicable in a data processing device comprising an output unit, a computer system and an embedded system, generate a control command for enabling an establishment of a channel for outputting data when it is determined that the computer system stays in a non-operating state, establish a data transmission channel between the embedded system and the output unit based on the control command, determine data to be outputted, and transfer the data to be outputted from the embedded system to the output unit through the data transmission channel. In this way, the method and apparatus according to the present invention can ensure that a user need not wait a long time for the computer's start-up, and can carry out an operation on local data for the computer in time, which improves the user satisfaction.

Data output method and apparatus

The present invention provides a computer system, a notebook computer and a method for controlling a computer system. The method comprises steps of: determining current state of the main computer subsystem; turning off the power of the embedded subsystem or enabling the embedded subsystem into a low-power state of the embedded subsystem when the main computer subsystem stays in a power-on state of the main computer subsystem; and enabling the embedded subsystem into an operating state of the embedded subsystem when the main computer subsystem stays in a low-power state or a shut-down state of the main computer subsystem. The computer system comprises: a power supply, a main computer subsystem and an embedded subsystem, wherein the main computer subsystem comprises a state determination module and a state control module for the embedded subsystem. The notebook computer comprises a main board, an embedded subsystem and a power supply, wherein the main board comprises an embedded controller and a power switch controller as well. With the above technical solutions, the power consumption caused by the embedded subsystem is reduced while implementing a preset function in real time.

Computer system and notebook computer, and method for controlling computer system

Disclosed is a hybrid-system computer comprising a first system, a second system and a power supply unit, wherein the power supply unit is connected to the first system and the second system, respectively, and wherein power consumption in an operating state of the second system is lower than that in an operating state of the first system; the hybrid-system computer further comprises: a triggering unit configured for obtaining a switching command when the first system is in an operating state and the second system is in a non-operating state; and a switching unit connected to the triggering unit, the first system and the second system, respectively, and configured for receiving the switching command and controlling the first system to enter a non-operating state and the second system to enter an operating state based on the switching command. With the hybrid-system computer, in the case that only low power consumption applications are required, the first system is caused to enter a non-operating state, and the second system is put into an operating state. Therefore, the overall power consumption can be effectively reduced.

The present invention provides a data processing device and a method for switching states thereof. The data processing device comprises an operating system and a communication interface for communicating with another data processing device, wherein the communication interface is enabled when the operating system stays in the operating state of the operating system, and the communication interface is disabled when the operating system stays in a low-power-consumption state. The method for switching states comprises the following steps of: detecting whether the communication interface stays in the operating state of the communication interface and generating detection information; determining whether the operating system stays in the operating state of the operating system when the detection information indicates that the communication interface stays in the operating state of the communication interface, and generating determination information; generating a system state holding command when the determination information indicates that the operating system stays in the operating state of the operating system; and controlling the operating system to stay in the operating state of the operating system based on the system state holding command. The present invention can not only secure communication via the data communication interface, but also allow the operating system to handle normally and stably an interrupt, so as to reduce the system power consumption.
