BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for preventing power consumption of a computer and a method of controlling the same. In particular, when a computer's operating mode is switched to a power saving mode, the computer shuts down the power applied after terminating the current operating state in a normal manner. A consumption preventing device and a control method thereof.

Portable computers that are generally used use a battery as a main power source, so they can input and process desired information regardless of time and place.

Therefore, the demand is rapidly increasing because it is very small and easy to carry, and the data processing capacity is also changed to a large capacity to realize rapid information processing and information communication required in a rapidly changing information society.

However, as the main power of the portable computer is generally supplied with the power required for operation using the limited power of the portable power supply, when the portable power is used up for a long time of use, there is a need to replace the new portable power immediately. do.

Therefore, many power management modes have been developed and used to efficiently use the limited main power capacity. When the computer is temporarily suspended, the power is gradually minimized through the steps of doze mode, standby mode, and rest mode to minimize power consumption.

Among the many power management modes described above, the sleep mode automatically saves the main power after storing the corresponding data according to the current working state when the portable computer is not operated in the operation state for a set time or more. In the suspend mode to reduce the unnecessary power consumption by turning off, and the main power is changed to the on state by the operation of the computer user in the suspend mode, the data stored in the memory device may be restored and the data may be processed. It is divided into resume mode to switch to the state.

When the corresponding data is stored in the memory device as described above, an auxiliary power source is installed to protect data stored in the volatile memory device regardless of the state in which the main power is off. It is supposed to be.

Therefore, a technique for preventing the problem of data stored in a memory device due to an abnormal state of an auxiliary power supply is disclosed in Korean Utility Model Registration Application No. 93-10581 (filed date: June 16, 1993). It is posted on the state sensing device of auxiliary power. In the above conventional technology, a memory device operating irrespective of the state of the main power source can prevent a problem that data stored due to insufficient capacity of the auxiliary power source is lost.

However, when switching to the resume mode by the user's operation in the suspend mode to prevent unnecessary consumption of the main power as described above, when the capacity of the main power is not charged to maintain the operation of the portable computer. The power may be turned off during the resume mode.

Therefore, a problem arises in that all data stored in the memory device is lost during the resume mode operation, resulting in the inconvenience of re-inputting the data again to execute the data processing and causing a lot of time loss.

Another power management mode is a hibernation mode. In the hibernation mode, when the state of the computer is switched to the rest mode, all information representing the current system state is stored in the hard disk, and then the power of the entire system to be supplied is changed to the off state to cut off the power supply.

When the power is applied again, power regardless of the operation of the computer system may be supplied regardless of whether the portable power is installed. However, when managing the power of the computer system as in the hibernation mode, all data representing the current system state is stored in the hard disk, and thus, if the hard disk is damaged or normal operation cannot be performed, all the stored data can be restored. No problem occurs.

As a result, all data is lost and work cannot continue, and all data required for operation must be re-entered, which wastes a lot of time and labor.

In addition, since the memory area for executing the data backup operation must be separately partitioned on the hard disk, the actual usable memory capacity is reduced.

In particular, when a large number of option cards are added to add various functions as well as the operation module installed in the computer system, the data stored in the hard disk through the operation of the power management mode as described above. Does not return normally.

In other words, the power management mode control operation inherent in the computer system does not support the additional option cards. Therefore, when the power is supplied again, the status of each option card is set to reset, but the data stored in the hard disk is normally restored. You may not be able to do this, or the computer system may crash during the setting operation.

Therefore, an object of the present invention is to solve the above-described problems, and when the computer system state is switched to the power management mode, to prevent power consumption of the computer to be able to switch to the power management mode after executing a normal shutdown command An apparatus and a control method thereof are provided. In accordance with an aspect of the present invention, a corresponding power management control signal is input according to an operation state of a computer system, and a keyboard for storing data for an end operation of an ongoing operation according to a user's selection operation. Controller; When data corresponding to a user's selection operation is input through the keyboard controller, control data for a job termination operation is output to the keyboard controller, and an operating state of the computer system in a power management mode according to the state of data input from the keyboard controller. In case of switching, the control unit is configured to switch to the power management mode after terminating the operation of the job being processed.

Another aspect of the present invention for achieving the above object comprises the steps of reading input data and determining whether end data of an operation to be executed is input; If the end data is input, storing the corresponding address in the memory and determining whether a power management control signal has been input; When the power management control signal is input, the corresponding end data stored therein is output, and then a control signal corresponding to the power management control signal is output.

Another aspect of the present invention for achieving the above object comprises the steps of: reading input data after outputting guide data for a user's selection operation; Setting the end data for terminating the task to be executed and outputting the input data to the keyboard controller when the read input data is data corresponding to the selection operation; The keyboard controller determines whether job termination data is input, and when the job termination data is input, ends the running task and executes an operation corresponding to a control signal input from the keyboard controller.

Hereinafter, with reference to the accompanying drawings will be described embodiments of the present invention; 1 is a block diagram of an apparatus for preventing power consumption of a computer according to an embodiment of the present invention, FIG. 2 is an operation flowchart of an operation control unit according to an embodiment of the present invention, and FIG. 3 is an operation of a keyboard controller according to an embodiment of the present invention. Flowchart.

Referring to the configuration of the present invention with reference to FIG. 1, the keyboard controller 10 capable of inputting data through an input device to which a corresponding power management control signal is input and connected according to an operating state of a computer system; And an operation controller 20 for inputting / outputting a data signal and a control signal with the keyboard controller 10 to control a power management mode operation of the computer system.

The operation of the present invention made as described above is as follows.

First, the operation state of the operation control unit 20 will be described with reference to FIG. 2.

In order to use the computer system, when power required for operation is supplied, the operation control unit 20 starts operation (S10).

Therefore, the operation control unit 20 first outputs data for selecting whether or not to use the operation of the present invention (S11).

In operation S12, data input from the keyboard controller 10 is read.

When the data read by the operation control unit 20 corresponds to the operation corresponding to the operation for which the operation of the present invention is selected (S13), the operation control unit 20 uses the data that is already stored in the memory device. Keyword data corresponding to the end operation is set (S14).

In operation S15, the corresponding keyword data set for ending the set operation is output to the keyboard controller 10.

However, when the state of the signal determined in the step (S13) does not perform a separate selection operation, the operation control unit 20 executes the operation of the normal operation control unit 20 (S18).

Therefore, in order to minimize power consumption, when the operating state of the computer system is switched to the power management mode, the user may execute the corresponding operation according to the selected operation.

When the corresponding operation according to the user's selection is executed as described above, the operation controller 20 reads data input from the keyboard controller 10 and determines whether data for ending the current operation is input ( S16).

If it is determined that the data for ending the job is input, the operation controller 20 executes an operation for executing an operation currently in progress (S17) and then executes a normal operation (S18).

However, when the data input for the end of the job is not made, the operation control unit 20 executes the corresponding operation normally (S18).

As described above, the operation control unit 20 may determine whether to execute the end operation of the job when the user enters the power management mode according to the user's selection operation.

Hereinafter, the operation of the keyboard controller 10 will be described with reference to FIG. 3.

If the power required for operation is also supplied, the keyboard controller 10 which starts the operation (S20) first reads the data input from the operation control unit 20 (S21), and determines whether keyword data for the end operation is input. (S22).

Therefore, when a corresponding keyword is input from the operation controller 20, the keyboard controller 10 stores the input data at a corresponding address of the memory device (S23).

In operation S24, it is determined whether a power management control signal for reducing power consumption is used.

When a control signal for separate power management is not input, the keyboard controller 10 performs a general normal operation (S29).

However, when a power management control signal corresponding to a case of not using the computer system for a long time in a power supply state is input, the keyboard controller 10 reads keyword data for a job termination operation stored at a corresponding address in the memory. After that (S25), it outputs to the operation control unit 20 (S26).

Accordingly, the operation controller 20 may stop the currently executing operation by outputting a signal corresponding to keyword data for ending the job output from the keyboard controller 10, that is, data for ending the job.

The type of the power management control signal is set using the state of the current input signal and the data already stored (S27) to recognize the type of the power management mode to be executed.

Therefore, when the type of the power management mode is set as the input of the power management control signal, the keyboard controller 10 outputs a corresponding control signal to the operation control unit 20 to execute the operation of the corresponding power management mode ( S28), it is possible to control the power state used to execute the operation of the power management mode. And the keyboard controller 10 goes to the first step (S12).

However, if the keyword control signal for the job termination is not input from the operation control unit 20 or if the power management control signal is not input in the step S24, the state of data input from the connected input device is determined and the corresponding signal is determined. The normal operation of executing the operation is performed (S29).

As described above, when the power management mode operation is executed according to the operation state of the computer system to manage the power consumption of the computer system, the power management mode is switched to the corresponding power management mode after executing the end operation of the current operation. You can safely manage your data.

In addition to the functions set by default in the computer system, even if the user enters the power management mode during the operation added to the user's needs, the computer system is added because the state of the computer system is changed after executing the normal operation termination operation. It is possible to prevent data loss or corruption when the module does not support power management mode operation normally.
