Description

Electronic device and wake-up method thereof

technical field

The present invention relates to an electronic device and its wake-up method, and in particular to an electronic device awakened by a network card and its wake-up method.

Background technique

In recent years, with the rapid development of computer technology, remote control technology has become more and more common. Users can operate remote computers via the network anytime and anywhere. For example, general users can use remote control to control the computer system in the office at home to obtain required data or perform remote operations. System administrators can also use remote control to obtain information such as the hardware status of the remote computer, system event log records, etc., so as to grasp the status of the computer system at any time.

Today's computer systems usually have a network card that supports the Wake on LAN (WOL) function, and can perform a wake-up behavior after receiving a wake-up request from another remote computer through the network card. Since this wake-up behavior enters into a partial wake-up mode through the network card wake-up, in this mode, only the user needs to provide remote data access, so there will be another part of the equipment (such as the screen, speakers, and CD-ROM drives, etc.) device) is still in a sleeping or off state to save power and avoid noise.

For example, please refer to Table (1). In the current computer state, there are partial wake-up state, display screen off (Displayoff) state, sleep (Sleep) state, hibernate (Hibernate) state and shutdown ( Shutdown) state, etc. Each state and its corresponding input unit have different wake-up results. For example, in the above-mentioned partial wake-up state, because some devices are still in the sleep or off state, the user may misjudge that the computer is still in the sleep state and perform wake-up actions, for example, press the power button, enter the keyboard Or the wake-up behavior of clicking the mouse, etc. That is to say, when the computer is already in the awakened partial wake-up mode, if the user presses the power button, the computer will execute the corresponding behavior of the power button (for example, dormancy, sleep or shutdown, etc.). Accordingly, unexpected results will be caused by users.

Table 1)

To sum up, how to solve the problem that the electronic device in the partial wake-up mode cannot be woken up to the normal operation state by pressing the power button, inputting the keyboard, or clicking the mouse is the goal that those skilled in the art are working on.

FIG. 2 is a flowchart of a method for waking up an electronic device according to an embodiment of the invention. Please refer to FIG. 1 and FIG. 2 at the same time. The method of this embodiment is applicable to the above-mentioned electronic device 100 . The detailed process of the method of this embodiment will be described below with various components of the electronic device 100 in FIG. 1 .

First, the input event filtering module 110 receives an input event triggered by the input unit 104 (step S201 ). In this embodiment, when the input unit 104 is a power button, the input event filtering module 110 triggers an interrupt event to the wakeup module 120 after receiving the input event triggered by the input unit 104 .

Next, the wake-up module 120 receives the interrupt event from the input event filter module 110, and determines whether the electronic device 100 is in a partial wake-up mode entered through wake-up via the network card 102 (step S203). The wake-up module 120 obtains wake-up information from the driver program of the network card 102 after receiving the interrupt event, and judges whether the electronic device 100 is in the partial wake-up mode based on it. Specifically, in the partial wake-up mode entered by being woken up by the network card 102, the electronic device 100 only wakes up the necessary components that allow the remote device to access data in the electronic device 100 through the network card, and the necessary components include the electronic device 100 One or a combination of processors, network cards, memory and hard disks. In other words, in this mode, only a remote device needs to be provided for data access to the electronic device 100. Therefore, there will be another part of the equipment in the electronic device 100 (for example, devices such as screens, speakers, and optical disk drives) are still in sleep or off state to save power.

In particular, in this embodiment, the interrupt event is a window management instrumentation (Windows Management Instrumentation, WMI for short) event. The window management specification is a core window (Windows) management technology developed by Microsoft Corporation. Users can use the window management specification to manage local electronic devices and remote devices, so as to obtain the internal status of local electronic devices and remote devices. Information. For example, a window management specification provides for starting a job on a remote device, getting a list of installed programs on a local or remote computer, setting a job to execute at a specific date and time, and querying the Windows Event logs and other services. For example, in this embodiment, when the wake-up module 120 receives a window management specification event, it will obtain wake-up information corresponding to the wake-up state of the electronic device 100 from the network card 102 of the electronic device 100 . Accordingly, the wake-up module 120 can know whether the electronic device 100 is in the partial wake-up mode according to the wake-up information.

Afterwards, if the wake-up module 120 knows that the electronic device 100 is in the partial wake-up mode according to the wake-up information, the wake-up module 120 wakes up the electronic device 100 to the normal operation mode (step S205 ). Here, the normal operation mode is, for example, the S0 state in the Advanced Configuration and Power Interface (ACPI) standard. In this normal operation mode, the devices and components of the electronic device 100 are enabled, and its operating system and applications The programs are also executed by the processor 108 . In other words, except for one or a combination of the above-mentioned processor, network card, memory, and hard disk of the electronic device 100, other devices and components of the electronic device 100 (for example, the screen, the speaker, and the optical disk drive) will all be in this normal operation mode. next to be awakened.

It is worth mentioning that since in this embodiment, the input unit 104 is a power button, if the wake-up module 120 knows that the electronic device 100 is not in the partial wake-up mode according to the wake-up information obtained, the wake-up module 120 will request The input event filtering module 110 transmits the control code (IOcontrolcode) of the power button to the power management interface of the electronic device 100, so that the electronic device 100 executes the corresponding action of the power button. Here, the power management interface is an advanced architecture and power interface (ACPI). That is to say, at this time, the electronic device 100 will perform the behavior corresponding to the power button according to the advanced architecture and power interface and the user's settings. The device 100 may enter sleep mode, shutdown mode, normal operation mode or perform no action.

Furthermore, in another embodiment, the input unit 104 may be a keyboard or a mouse. In this case, the wake-up module 120 will intercept (hook) the input event triggered by the keyboard or the mouse, in other words, the input event triggered by the keyboard or the mouse will be received by the wake-up module 120 . After the wake-up module 120 receives the input event triggered by the keyboard or the mouse, the wake-up module 120 will execute the above-mentioned step of judging whether the electronic device 100 is in the partial wake-up mode entered by waking up via the network card 102 (step S203). Recap. If the wake-up module 120 determines that the electronic device 100 is in the partial wake-up mode, the wake-up module 120 will directly wake up the electronic device 100 to the normal operation mode. On the contrary, if the wake-up module 120 judges that the electronic device 100 is not in the partial wake-up mode, the wake-up module 120 will perform the corresponding behavior of the mouse or the keyboard or not perform any action. Therefore, the electronic device 100 will enter the corresponding mode according to the following table (2). status or continue in its current status.

Please refer to Table (2), as mentioned above, in the current computer state, there are partial wake-up state, display screen off (Displayoff) state, sleep (Sleep) state, hibernate (Hibernate) state and shutdown ( Shutdown) state, etc. Each state and its corresponding input unit have different wake-up results. Especially, in the partial wake-up state, through the wake-up method of the electronic device of the present invention, when the user performs a wake-up action, for example, pressing the power button, typing a keyboard or clicking the mouse, the wake-up module 120 of the electronic device 100 will The operation of waking up the electronic device 100 to a normal operation mode is performed. Accordingly, when the user performs the behavior of waking up in the partially aroused state, the expected result can be obtained.
