A method of setting specific scan codes for a manual input device includes the steps of establishing a transmission channel between the manual input device and a scan code register of a computing device, receiving at least one scan code, which corresponds to at least one input key of the manual input device and is for setting a customized specific code for enabling the computing device to perform a specific function, from the manual input device, saving the customized specific code to the scan code register of the computing device, and closing the transmission channel.

A computer system for processing data in a non-operational state and processing method thereof are provided. The computer system includes a data output unit, a data source, a data processing module and a state monitor unit. The data processing module accesses and processes data from the data source, and transmits the processed data to the data output unit. The state monitor unit monitors a power supply state of the computer system to generate a state switch signal, which indicates whether the computer system is in an operational state or a non-operational state. When the state switch signal indicates that the computer system is in a non-operational state, the data source and the data processing module receives operating voltages to access and process data.

A bus cycle trapping system includes at least one register, a north bridge, a south bridge and a central processing unit (CPU). The register is configured to store at least one trapping parameter. The north bridge traps a bus cycle matching the at least one trapping parameter while issuing an activating signal. The south bridge sends a system management interrupt message according to the activating signal. The CPU enters a system management mode according to the system management interrupt and executes a system management interrupt routine for doing a debugging test of the bus cycle matching the trapping parameter.

A power saving method and system thereof is disclosed. When the central processing unit is under a non-snooping sleep state and a peripheral device sends a bus master request, a chip will drive the central processing unit waking from the non-snooping sleep state and entering a system management mode for executing an interrupt service routine that makes the central processing unit in halt status. The central processing unit is then driven to enter a snooping sleep state for snooping the bus master request. After the execution of the bus master request, the chip will drive the central processing unit to leave the snooping sleep state and return to the non-snooping sleep state for power consumption conservation.

A method and apparatus for driving a non-native SATA hard disk applied in a computer is provided. The computer includes a basic input/output system (BIOS) and an operating system (OS), both of which support an advanced configuration and power interface (ACPI). The non-native SATA hard disk includes a conversion interface and a parallel ATA (PATA) internal disk. First, issue an interrupt. Then, process an interrupt handle routine for detecting and saving the timing mode of the PATA internal disk. Next, load a default IDE driver. Then, report the saved timing mode. Finally, set the SATA hard disk according to the timing mode.
