However, since the computer is not always used at home or at work, it is a reality that the computer turns on even when not in use, which consumes a lot of power unnecessarily.
As the use of computers has become commonplace, power consumption by the power of computers has already become a social problem. Accordingly, activities to save the use of computers have been made. In addition, efforts have been made to technically reduce power consumption by such computers.
However, until now, technology has been introduced to save power by using only the presence or absence of computer, and the computer is more efficient in consideration of the user's computer usage situation such as the frequency and frequency of the computer user as well as the time when the user is away. No techniques have been introduced to conserve power.
For example, even when the computer user is away for a while, the user enters the standby mode immediately after leaving the computer and waits for four seconds to exit the power saving mode when the computer user returns to the seat. If the user resumes using the computer after entering the hibernation mode, the user may have to wait a longer time, which may cause inconvenience to the user who is away for a short time.
The present invention is to solve the above-described problems, an object of the present invention is to analyze the user's computer usage habits to save power step by step according to the possibility of using the computer, in particular, in consideration of the number of times and time away When the user is away from the computer, each power saving mode entry time is set in advance according to the user's computer usage habits so that the user can enter the power saving mode step by step so that the user's convenience and efficient power saving effect can be obtained.

In this case, when the same user ID as the user authentication information is received or when there is at least one input signal among a keyboard, a mouse, and a power switch, the power saving mode may be released.
On the other hand, the control unit may operate the timer when a user ID equal to the previously stored user authentication information is not received or when no information is received as a result of the analysis of the user authentication analyzer.
In addition, the step-by-step mode conversion unit may perform a step-by-step conversion to the power saving mode corresponding to the power saving mode entry time, the power saving mode may include at least one or more of the monitor off mode, the standby mode and the maximum power saving mode. .
According to an aspect of the present invention, there is provided a power saving method according to a mode conversion in accordance with one aspect of the present invention, comprising: a first step of analyzing a received user ID and pre-stored user authentication information; Operating a timer when there is no user ID information corresponding to the previously stored user authentication information or no information is received as a result of the analysis; And performing a conversion to a corresponding power saving mode when the timer count value reaches a preset power saving mode entry time.
In this case, when the same user ID as the user authentication information is received or when there is at least one input signal among a keyboard, a mouse, and a power switch, the power saving mode may be released.
The power saving mode may include at least one of a monitor off mode, a standby state entry mode, and a maximum power saving mode.

As shown, the power saving method by the step-by-step mode conversion, first, receives the user ID information from the
After receiving the user ID information, it is determined whether the user ID is normally received (S20). If it is determined that the user ID is not received, the timer operation is performed.
On the other hand, after receiving the user ID information, the predetermined user authentication information and the user ID information is compared (S30), and it is analyzed whether the same user ID information exists (S40).
If the user ID information corresponding to the previously stored user authentication information exists in the received user ID information, the energy saving mode is canceled and the process returns to the first step of receiving the user ID information (S50).
As a result of the determination, when the user ID information corresponding to the user authentication information stored in advance does not exist in the received user ID information, the timer operation is performed (S60).
On the other hand, after the timer operates, if there is no user ID corresponding to the user authentication information, the count value continues to increase, and it is determined whether the count value reaches the preset power saving mode entry time (S70).
As a result of the determination, when the counted value does not reach the preset power saving mode entry time, it is determined that the computer user is using the computer, thereby maintaining the normal operation state of the computer and returning to the user ID information receiving step (S10). .
As a result, when the user ID is not confirmed within the preset power saving mode entry time and the counted value reaches the preset power saving mode entry time, the power saving mode is switched to the power saving mode step by step according to the power saving mode entry time set for each power saving mode. (S80)
For example, it is checked whether a user ID corresponding to the user authentication information is received at a predetermined time interval or at a predetermined power saving mode entry time for each power saving mode after the timer operates. First, when the user ID corresponding to the user authentication information DB is not received until the preset first power saving mode entry time is reached, the mode is switched to the first power saving mode, that is, the monitor is turned off. After entering the first power saving mode, if the user ID corresponding to the user authentication information DB is not received continuously until the preset second power saving mode entry time, it is converted into the second power saving mode, that is, the standby mode. Finally, if the user ID corresponding to the user authentication information DB does not exist until the third power saving mode entry time after the standby mode conversion, the mode is converted into the third power saving mode, that is, the hibernation mode.
However, when changing the power saving mode in the above steps, if there is an external input such as a mouse, keyboard, power switch or the received user ID corresponds to the user authentication information DB, the power saving mode is canceled and normal power supply, that is, normal computer operation. This is done.
On the other hand, the power saving method by the step-by-step mode conversion described above can be implemented by a computer-readable recording medium recording a program.
The invention is not to be limited by the foregoing embodiments and the accompanying drawings, but should be construed by the appended claims. In addition, it will be apparent to those skilled in the art that various forms of substitution, modification, and alteration are possible within the scope of the present invention without departing from the technical spirit of the present invention.
