When the dormant startup module 150 receives == b tiger SSL, the dormant startup module 15 causes the electronic health (8) to enter a dormant state. Alternatively, the dormant activation module 15 can cause the electronic device to perform a power saving mode or a standby state, which can be changed according to the circuit design or the general knowledge in the field, and the embodiment of the present invention is not limited thereto. Moreover, the sleep activation module 150 can determine the portion of the electronic device 110 to sleep (or enter the standby mode or the power saving mode) according to the current state. Here, the electronic device 100 is taken as an example of a personal computer or a smart phone. The electronic device 100 can determine the 201250458 sorrow based on the application or interface of the user's operation, and determine the length of the sleep time according to the current state. Assume that when a user watches a movie by playing a software, the length of a typical movie will not exceed three hours, and the user may not enter any control commands when watching a movie (four) (ie, the user within three hours of starting the video playback) Will not operate the electronic device). At this time, when the current state is a movie (corresponding to the current state si in Table 1), the electronic device 100 can be set to sleep after three hours (or enter the standby mode or the power saving mode), and the entire electronic device 100 can enter the sleep state. . Suppose that when a user edits a file through the editing software, the user inputs a command most of the time, so the gap of the command input is short. At this time, when the current state is editing (corresponding to the current state S2 in Table 1), the electronic device 100 can be set to sleep after three minutes (or enter the standby mode or the power saving mode), and the entire electronic device can be Go to sleep. Assume that when a user browses a webpage through webpage browsing software, since the user needs some time to browse the content of the webpage, the gap of the instruction input is longer. At this time, when the current state is browsing (corresponding to the current state S3 in Table 1), the electronic device 1 can be set to sleep after ten minutes (or enter the standby mode or the power saving mode) and the entire electronic device 100 can be Go to sleep. Assuming that the user listens to music through the music playing software, since the listening music does not need to be displayed, the electronic device 10 can be quickly put to sleep to turn off the display portion of the electronic device. At this time, when the current state is music (corresponding to the current state S4 in Table 1), the electronic device 1 can be set to 3 after 201250458 minutes to sleep (or enter the standby mode or the power saving mode), and the display portion can be made to enter Sleep. Here, the electronic device 100 is taken as an example of a television. The electronic device 1 QQ can be poor. The input source determines the current state and determines the length of the sleep time according to the current state. Assuming that the input signal source is a high-resolution multimedia interface (HDMI), since most of the HDMI is the k-number that receives the video playback ^, it means that the user wants to watch the movie. At this time, when the current appearance is a movie (corresponding to the current state S1 in Table 1), the electronic device can be set to sleep after two hours (or enter the standby mode or the power saving mode). Assuming that the input signal source is a cable, the general cable is a transmission TV signal, and most of the TV programs will not exceed two hours. At this time, when the current state is television (corresponding to the current state S6 in Table 1), the electronic device 100 can be set to sleep after two hours (or enter the standby mode or the power saving mode). However, depending on the occasion of use, the sleep time can also be adjusted accordingly. If the electronic device 100 is used in an exhibition or a store, the store can be set to operate for eight hours or ten hours or never enter a sleep state (or standby). Mode, power saving mode), which can be determined according to the needs of users. Here, the electronic device 1 is used as a driving recorder or satellite navigation as an example. The electronic device 100 can determine the current state according to the input signal source, and determine the length of the sleep time according to the current state, and determine whether the electronic device 100 is operated according to whether the input signal is the same or not. During the vehicle's travel, the position of the navigation will change continuously (that is, the input signal will continue to be received, or the input signal will be different), and the captured image will be different (also the input signal will be different in 201250458). At this time, the electronic device will just be It is judged that it is used so that the time counting result is continuously reset, so that the electronic device just does not enter the sleep state (or the standby mode, the power saving mode). Assume that the time when the vehicle is parked is generally 5 minutes, then when the current state is navigation (corresponding to the current middle state S5), the electronic device 1 can be set to sleep after five minutes (or it is standby; J: Assign or save power mode), to avoid the electronic device 1GG entering the sleep state (or standby mode, power saving mode) at the time of the stop. Thereby, the electronic device 1 can be prevented from going to sleep (or in the standby mode and the power saving mode) while the vehicle is running. Moreover, if the user feeds the electronic device 1GG, since the vehicle is no longer traveling, the navigation position will not change (that is, there is no input signal or the input signal is the same), and the captured image is the same (ie, lost) The second signal is the same). At this time, the electronic device 100 judges that it is not used, and automatically enters a sleep state (or standby mode, power saving mode) after five minutes: FIG. 2 is a flowchart of a sleep method of the electronic device according to an embodiment of the present invention. . Please refer to the item 2 'In this embodiment', the time will be counted first (step S210. Then, it is detected whether the state of the electronic device is changed (S22〇). When the state of the electronic device changes, that is, the judgment result of step S220 is "Yes", the corresponding sleep time is searched according to the current state, and the time setting signal is generated according to the sleep time, and the reset time count result is obtained (S23〇). Next, returning to the dream S210 to continue the time counting. When the step S220 is performed If the determination result is "No", the user is detected whether the electronic device is operated (step S240). When the user operates the electronic device, that is, the step S24 is determined to be 201250458 疋 '', a time reset signal is generated. The result is counted by the reset time ♦ 2 'S250). Then, the process returns to step S21 〇 to continue the time counting. If the result of the determination in step S240 is "NO,", the time count result is judged to be f at the sleep time (step S26G). ). When the time count result is not equal to the rest, the judgment result of step S26 is "NO", then return to step = 10 to continue the time count; when (4) the count result is equal to the tilt time, the judgment of 2 step S2 6G The result is "Yes, then, the electronic device is put into hibernation 7' [, the order of the above steps is for explanation, the embodiment of the present invention = limited thereto" and the details of the above steps can be referred to the electronic device 1 The description of the electronic device and the sleep method thereof according to the embodiment of the present invention are based on the current state to find the corresponding sleep _, and when the time count result is equal to the sleep time, the electronic device Into the sleep state S. Thereby, the device can adjust the sleep time according to the current state, can avoid the electronic device from being used without being used to enter the sleep state. Although the invention has been disclosed by the above embodiment, it is not used In order to limit the invention, it is to be understood by those skilled in the art that the present invention may be modified and modified without departing from the spirit and scope of the invention. The scope of the invention is defined by the scope of the appended claims.
