In this embodiment, the remote user 50 can access the data in the electronic device 10 through the network interface module via the Internet 20.

FIG. 2 is a flow chart illustrating a method of controlling an electronic device 10 according to an embodiment of the invention. Referring to FIG. 2, the control method of the present embodiment is applied to the electronic device 10 of FIG. Hereinafter, the control methods described in the embodiments of the present invention will be described with respect to various components and modules in the electronic device 10. The various processes of the method can be adjusted accordingly according to the implementation situation, and are not limited thereto.

In step S210, when the electronic device 10 enters a sleep state (for example, the S3 sleep state of the advanced configuration and the power interface standard), the processing unit 125 enables the silent wake-up function of the electronic module through the silent wake-up command.

For example, when the processing unit 125 receives a user's sleep operation (eg, an application loaded via the electronic device 10, a power button or button on the electronic device 10) or any other triggering action (eg, the screen closure of the electronic device 10, A sleep trigger condition such as a standby time exceeding a certain time (for example, 10 minutes, 30 minutes, etc.) causes the electronic device 10 to enter a sleep state. Next, the following embodiments will respectively describe the silent wake-up function corresponding to each electronic module.

In one embodiment, the processing unit 125 causes the optical disk reading device 135 to be in a power-unturned state in accordance with a peripheral optical disk device control command. Specifically, the processing unit 125 transmits a corresponding function (for example, a command function, an input/output control I/O control function) through a driver that supports a transmission interface connected to the optical disk reading device 135. And so on, the optical disc reading device 135 is controlled by transmitting a peripheral optical disc device control command (for example, a disc device sleep command). When the optical disc reading device 135 receives the optical disc device sleep command transmitted by the processing unit 125, the optical disc reading device 135 switches to the power-unturned state (for example, the unreadable state or the initialized state). For example, the content of the optical disc in the optical disc reading device 135, the state in which the optical disc is ejected, and the state in which no optical disc is present cannot be read. Then, the electronic device 10 is in a sleep state.

In this embodiment, the processing unit 125 transmits a disc device sleep command to the optical disc reading device 135 through a driver of the peripheral device interface, wherein the peripheral device The driver includes an Advanced SCSI Programming Interface (ASPI) driver. Specifically, the Small Computer System Interface (SCSI) is suitable for use between electronic devices (personal computers, notebook computers, etc.) and their peripheral devices (hard disk, flexible disc drive, optical disc). Standard specifications for the interface between the reading device, printer, scanner, etc.). The SCSI standard specification defines a common command set for peripheral devices that support SCSI. These commands directly control peripheral devices that support SCSI. In general, it is quite complicated to transfer correct and direct operational commands to control SCSI-enabled peripherals, but programmers can use the ASPI higher-order functions to transmit the correct SCSI commands through the ASPI driver. In this embodiment, the processing unit 125 transmits the disc device sleep command to the optical disc reading device 135 through an ASPI driver.

For example, under Win32, the ASPI Manager (for example, wnaspi32.dll, aspi32.sys, winaspi.dll, etc.) provides functions to transfer instructions to peripheral devices, such as DWORD SendASPI32Command. (LPSRB). Further, the function includes a disc device sleep instruction suitable for the disc reading device 135 (for example, [F3 0D 3D 00 00 00 00 00 00 00 00 00]). When the optical disk reading device 135 receives the optical disk device sleep command, the optical disk reading device 135 can be switched to the unreadable state.

In addition, before the driver transmits the sleep command, in an embodiment, the processing unit 125 confirms whether the driver of the peripheral device interface is installed and whether the electronic device 10 is connected to the optical disk reading device 135 through the peripheral device interface. For example The function provided by wnaspi32.dll is, for example, DWORD GetASPI32SupportInfo(void), wherein if the function cannot be executed or a specific message is obtained (for example, the optical disk reading device 135 is not connected to the electronic device 10 through SCSI), the processing unit 125 The above command function (i.e., DWORD SendASPI32Command (LPSRB)) cannot be used to transmit a sleep command to the optical disk reading device 135. On the contrary, the processing unit 125 can transmit the disc device sleep command to the optical disc reading device 135 through the ASPI driver.

It should be noted that, in the embodiment of the present invention, the function of the function of the function of the optical disc or the optical disc device can be changed according to the design requirement, and the present invention is not limited. In addition, in other embodiments, other peripheral devices (for example, DOS, FreeDOS, Linux) can also be used to support other peripheral device transmission interfaces (eg, USB, SATA, etc.) (for example, WinUSB.dll, ahci. c, etc.) to transmit a sleep command to the optical disk reading device 135, depending on the design requirements of the present invention. Further, the optical disk reading device 135 needs to set a corresponding optical disk device sleep command in advance so that the optical disk reading device 135 can enter the unreadable state after receiving the optical disk device sleep command.

In another embodiment, when the processing unit 125 receives the user's sleep operation or any other triggering action, the processing unit 125 transmits a display setting command to the display module 110 to cause the processing unit 125 to display according to the display setting instruction. The module 110 does not display a picture. For example, the electronic device 10 does not illuminate the backlight unit of the display module 110 or does not drive the pixels. Alternatively, the display module 110 may be set to a specific brightness (for example, 10 lumens, lm, 20 lumens, etc.) according to a display setting command.

In still another embodiment, when the processing unit 125 receives the user's sleep operation or any other triggering action, the processing unit 125 transmits a corresponding hard disk control command to the hard disk module 115. This hard disk control command is, for example, a power-up in standby (PUIS) command. After the hard disk module 115 receives the power-on command, the hard disk module 115 is in the power supply standby state, so that the processing unit 125 can access the hard disk through a function provided by the operating system (for example, DeviceIoControl). The module 115 issues instructions such as a Serial Advanced Technology Attachment (ATA), IDE, SATA, SCSI, and the like.

In another embodiment, when the processing unit 125 receives the user's sleep operation or any other triggering action, the processing unit 125 acquires and stores the volume state of the audio module 120 (eg, volume level, equalizer mode, bass processing). Mode, etc.). In addition, the processing unit 125 transmits a volume control command to set the audio module 120 to the silent mode. For example, the GetMute function provided by the interface of the IAudioEndpointVolume is used to obtain the current mute state, and the SetMute function is set to mute. Alternatively, processing unit 125 may set audio module 120 to a particular volume value (eg, 0 decibels, 5 decibels, 15 decibels, etc.). For example, set the volume value through the SetMasterVolumeLevel function provided by the IAudioEndpointVolume interface.

In still another embodiment, the processing unit 125 stores the processor state of the processing unit 125 when the processing unit 125 receives a sleep operation of the user or any other triggering action. For example, through the PowerReadACValueIndex and PowerReadDCValueIndex functions provided by the operating system. Power options for processor state (eg, minimum and maximum processor state). In addition, processing unit 125 uses processor setting instructions to set itself to a low performance state (eg, to reduce operating frequency, turn off one or more processing units in processing unit 125, etc.). For example, the power options of the processor state are set by the PowerWriteACValueIndex and PowerWriteDCValueIndex functions provided by the operating system. The fan module 130 adjusts, for example, the rotational speed of the blade assembly, the voltage or current of the fan module 130, and the like according to the processor setting command of the processing unit 125. For example, slow down the speed of the blade assembly.

Next, in step S230, when the electronic device 10 receives the wakeup event, the embedded controller 150 determines whether the wakeup event belongs to the remote wakeup event. In this embodiment, the network wake-up pin in the GPIO of the embedded controller 150 is connected to the network interface module 160, and when the electronic device 10 receives the wake-up packet from the Internet 20, for example, the remote end is triggered. During the wake-up event, the network interface module 160 notifies the embedded controller 150 by controlling (eg, pulling down, pulling up, etc.) the network wake-up pin connected to the embedded controller 150, so that the embedded controller 150 knows A remote wakeup event from the network.

In other embodiments, the embedded controller 150 can monitor the normal wake-up event corresponding to the user's wake-up operation via a normal wake-up pin other than the network wake-up pin. In this embodiment, the normal wake-up event may be that the embedded controller receives power-on, touch operation, mouse operation, and keyboard operation. For example, when the electronic device 10 is in the S3 sleep mode, a button (for example, a space button) in the keyboard provided by the electronic device 10 is embedded when receiving a button signal generated by the user pressing. The controller 150 can monitor this normal wake event via, for example, the processing unit 125, a keyboard, or the like. In another example, when the electronic device 10 is in the S3 sleep mode, for example, the touch panel receives the touch operation, the power button receives the power start, or the real-time clock (RTC) alarm is triggered. Behavior, etc., the embedded controller 150 can also monitor a normal wake-up event through a peripheral device-related operation such as a mouse operation or a normal wake-up pin of the processing unit 125.

It should be noted that the inventor of the present invention can design a wake-up event that can be monitored by the embedded controller 150 according to the requirements thereof, that is, when the electronic device 10 is in the sleep state, the embedded controller 150 can monitor some or all of the wake-ups. Events, and not limited to this.

In step S250, if the embedded controller 150 determines that the wakeup event is a remote wakeup event, the silent wakeup function is used to maintain the electronic module in a silent wakeup state. Specifically, in the computer system of the existing electronic device 10, when the computer system enters a sleep state, the basic input/output system 140 turns off the power of the display module 110, the audio module 120, and the optical disk reading device 135, or Some or all of the electronic modules are set to, for example, standby, power saving, low power operation, and the like. When the electronic device 10 wakes up from the sleep state, the BIOS turns on or sets the power of some or all of the electronic modules to a normal operating state and the like. For example, after the power of the optical disk reading device 135 is turned on, if an optical disk (for example, a CD, a DVD, or the like) exists in the optical disk reading device 135, the optical disk reading device 135 starts to read the content of the optical disk. The motor in the disc reading device 135 emits a read sound. Alternatively, the display module 110 displays a screen, and the audio module 120 continues to play the playback of the electronic device 10 before it sleeps. The music, the fan assembly of the fan module 130 rotates at a high speed to generate noise, or the hard disk module 115 accesses the operation to generate noise.

In an embodiment of the invention, the electronic module maintains the silent wake state set in step S210. For example, the display module 110 still does not display a picture. For example, the backlight of the display module 110 is not lit. The hard disk module 115 is in a power supply standby state. The audio module 120 is set to be muted. Alternatively, the processing unit 125 and the fan module 130 are in a low performance state. For example, the operating frequency of the processing unit 125 is lowered, one or several processing units 125 of the processing unit 125 are turned off, the rotational speed of the blade assembly of the fan module 130 is slowed down, and the like. Thereby, when the remote user 50 evokes the electronic device 10 from the far end, the electronic device 10 can operate in a power-saving, silent, and non-light state without affecting the surrounding personnel.

In addition, in an embodiment, before the optical disk reading device 135 has not released the unreadable state, when the reading operation of the processing unit 125 for the optical disk reading device 135 occurs, the optical reading device 135 receives the relevant information. A reply to the status is read and the read action is disabled. Specifically, when the electronic device 10 wakes up from the sleep state or is in a normal state (for example, the S0 normal working state in the ACPI standard), if the processing unit 125 automatically reads or receives the user's read operation, the optical disc The reading device 135 does not perform a read operation, but transmits a reply related to an unreadable state (for example, a message, an instruction, a change pin state, etc.). Upon receiving the reply, the processing unit 125 can know the existence of the optical disk reading device 135, but will not continue to read the contents of the optical disk in the optical disk reading device 135.

For example, in the windows operating system, when the electronic device 10 receives When the user clicks on an icon corresponding to the optical disc reading device 135 in the computer page, for example, regardless of whether or not the optical disc is present in the optical disc reading device 135, the corresponding page of the computer page corresponds to the optical disc. The icon of the reading device 135 is displayed as a matte disc, or a prompt message is generated (for example, it cannot be read, no disc in the disc player, etc.).

In other embodiments, if the processing unit 125 reads the content of the optical disc in the optical disc reading device 135, the optical disc reading device 135 may not transmit a reply, so that the processing unit 125 considers the optical disc reading device 135 to be inactive, dormant or paused. status.

Thereby, when the optical disk reading device 135 maintains the unreadable state, the processing unit 125 will be unable to read the contents of the optical disk in the optical disk reading device 135. Moreover, before the unreadable state has not been released, the processing unit 125 cannot read the contents of the optical disc in the optical disc reading device 135 regardless of whether the electronic device 10 is in a sleep state or a normal state. In the following, an embodiment will be described to explain how to cancel the silent wake-up state of the electronic module.

In an embodiment, when the electronic module is maintained in the silent wake state, if the embedded controller 150 further receives the normal wakeup event, the processing unit 125 returns the electronic module from the silent wake state to the normal operating state. Specifically, when the embedded controller 150 receives a normal wake-up event through a normal wake-up pin connected to a peripheral device such as a keyboard, a touch pad, a power button, a mouse, or the like, or the processing unit 125, the embedded controller 150 can It is determined that the normal wake-up event does not come from the Internet 20, and the processing unit 125 also restores the electronic module to the normal operating state. For example, the processing unit 125 turns on and drives the pixels of the backlight element of the display module 110. The processing unit 125 can access the files in the hard disk module 115. Processing unit 125 can read steps The volume state stored in step S210 is restored to the volume state according to the stored volume state. The processing unit 125 can read the processor state stored in step S210, and restore the processing unit 125 and/or the fan module 130 back to the processor state according to the stored processor state (for example, through the PowerWriteACValueIndex and PowerWriteDCValueIndex described above). Function to set the power option).

In an embodiment, when the embedded controller 150 receives the normal wake-up event, the peripheral optical disk device control command (for example, the optical disk device wake-up command) is transmitted to the optical disk reading device 135 according to the wake-up operation, so that the optical device wake-up command cannot be cancelled. Read status. Specifically, when the embedded controller 150 receives an application loaded by the user, for example, through the electronic device 10, a button on the electronic device 10, a button on the optical disk reading device 135, or any other triggering action (for example, the electronic device 10 When a wake-up operation of a specific time (for example, 10 minutes, 20 minutes, etc.) elapses after the sleep state wakes up, the processing unit 125 transmits a function of the driver through the transmission interface that supports the connection with the optical disk reading device 135 (for example, The DWORD SendASPI32Command (LPSRB) described above transmits a disc drive wake-up command (for example, [F3 0D 3E 00 00 00 00 00 00 00 00 00]) to the optical disc reading device 135 for the optical disc reading device 135. When the optical disk reading device 135 receives the optical disk device wake-up command, the optical disk reading device 135 can cancel the unreadable state. That is, the processing unit 125 can read the contents of the optical disc in the optical disc reading device 135.

For example, after receiving the wake-up command of the optical disc device, the optical disc reading device 135 starts the initialization program and processes it during or after the initialization process. The unit 125 can read the contents of the disc in the optical disc reading device 135. It should be noted that, in the embodiment of the present invention, the function or the optical device wake-up command can be changed according to the design requirement, and the present invention is not limited.

Referring to FIG. 3A, if the electronic device 10 receives a normal wake-up event (for example, the power button configured on the electronic device 10 is pressed) (step S310), the processing unit 125 turns on the power of the display module 110 through the BIOS (step S330). ).

In step S370, the electronic device 10 receives the remote wake-up event, but the display module 110 is still powered off. In step S390, for example, the mouse connected to the electronic device 10 receives the user's moving operation, and the processing unit 125 turns on the power of the display module 110 through the BIOS.

FIG. 4A is an example of a timing diagram of a general hard disk module 115. Referring to FIG. 4A, if the electronic device 10 receives a normal wake-up event (for example, the keyboard connected to the electronic device 10 is pressed) (step S410), the processing unit 125 can also access the data of the hard disk module 115 (step S430). ). On the other hand, 4B is an example of a timing diagram of the hard disk module 115 according to an embodiment of the present invention. Referring to FIG. 4B, when the system state of the electronic device 10 enters the S3 sleep state of the ACPI, the processing unit 125 transmits a PUIS command to switch the state of the hard disk module to the standby standby state (step S450). In step S470, the electronic device 10 receives the remote wake-up event, but the hard disk module state remains in the standby state. In step S490, for example, the electronic device 10 is connected.
