1 is a flow chart of a method for switching a fashion peripheral device in a power management mode according to an embodiment of the invention. Referring to FIG. 1, the embodiment is suitable for loading and unloading peripheral devices by an electronic device, such as a desktop device, a notebook computer, a workstation, etc., and the peripheral device is, for example, a universal serial bus ( Universal Serial Bus (USB) interface or Thunderbolt interface to connect electronic devices such as hard drives, pen drives, optical discs, graphic processing units (GPUs), displays or CD players. The detailed steps of the peripheral device attaching and detaching method of the present embodiment will be described below. First, the peripheral device is mounted on the electronic device (step S102). its In the normal operation mode (ie, S0), for example, the device detects whether a peripheral device is connected to the electronic device, and when the user connects the peripheral device to the electronic device (for example, inserting the USB plug of the peripheral device into the electronic device) When the USB socket is used, the electronic device detects the insertion of a new peripheral device and recognizes the type and specifications of the peripheral device, thereby automatically executing the driver of the peripheral device to drive the peripheral device.

After the peripheral device is driven, the electronic device can use the functions provided by the peripheral device. The user can execute the related application of the peripheral device and control the peripheral device or the function of the peripheral device through the application. Wherein, when the upper cover of the electronic device is closed, the operating system of the electronic device is ready to enter a power saving mode such as a sleep mode (sleep mode, ie, S3 mode) or a hibernate mode (hibernate mode). At this time, the electronic device first forcibly closes at least one program associated with the peripheral device to remove the peripheral device (step S104). The electronic device, for example, first turns off an application that is being executed by the electronic device and uses the function of the peripheral device, and after the application is closed, removes the driver of the peripheral device, thereby completing the peripheral device completely and safely. The ground is removed, and it can be ensured that the removal of the peripheral device does not cause the data of the electronic device to be lost or the system to collapse.

Finally, after the above-described program associated with the peripheral device is turned off, the electronic device enters the power saving mode (step S106). Wherein, by the step of automatically removing the peripheral device, it is ensured that in the power saving mode, when the peripheral device is removed, the data transmitted between the electronic device and the peripheral device is not lost, and the peripheral device is not lost. Being removed caused the system to crash.

For example, if the peripheral device mounted on the electronic device is an external device A graphic processing unit (GPU) is connected, and the electronic device uses a graphics processing unit to assist it in performing graphics operations in an active mode. Wherein, when the upper cover of the electronic device is closed, generally the user has finished the operation of the electronic device, and if the user wants to leave the site, the external graphic processing unit may need to be removed. At this time, the connection between the electronic device and the graphics processing unit still exists, and the work performed therebetween is only temporarily interrupted. If the user forcibly removes the graphics processing unit, it is highly likely that the data of the electronic device is lost or the system is collapsed. Therefore, in the embodiment, when the upper cover of the electronic device is closed, all programs related to the peripheral device on the electronic device are forcibly closed to remove the peripheral device, thereby avoiding the above situation.

It should be noted that the above embodiment only describes the removal mode of the peripheral device only when the cover of the electronic device is closed. However, in the case where the cover of the electronic device is not closed, the present invention also provides a corresponding removal mode to appropriately dismount the peripheral device corresponding to different operations of the user, thereby avoiding data loss or system collapse.

Wherein, after the electronic device completes the relevant steps of entering the power saving mode, the state 214 of the power saving mode (S3 or S4) is entered (step S308). At this time, if the electronic device receives the wake-up signal triggered by the user opening the upper cover, it will wake up from the power-saving mode, enter the state 202 of the normal operation mode (S0) again, and re-detect the peripheral device and execute the peripheral device. The driver to drive the peripheral device (step S310).

On the other hand, in the state 204, if the user does not close the upper cover, the user enters the upper cover open state 208, and when receiving the trigger signal for receiving the user control electronic device to enter the power saving mode, enters a prompt to close the peripheral device related program. State 210, thereby prompting the user to close the program associated with the peripheral device on the electronic device (step S312).

If the user has closed the relevant program, the state 212 in which the peripheral device has been removed is entered. Wherein, after the electronic device completes the relevant steps of entering the power saving mode, it enters the state 214 of the power saving mode (S3 or S4) (step S316). At this time, if the electronic device receives When the user presses the wake-up signal triggered by the button (hardware button or software button), it will wake up from the power-saving mode, enter the state 202 of the normal operation mode (S0) again, and re-detect the peripheral device and execute the peripheral device. The driver to drive the peripheral device (step S318).

On the other hand, in the state 210, if the user does not close the related program, the electronic device stores the context information of the program (step S320), and enters the state 214 of the power saving mode (S3 or S4) ( Step S322). At this time, if the electronic device receives the wake-up signal triggered by the user pressing the button (hardware button or software button), it will wake up from the power-saving mode, enter the state 202 of the normal operation mode (S0) again, and read The background information of the previously stored program is returned to the execution state of the program (step S324).

It should be noted that, in the state 214 where the user has not turned off the related program and the electronic device has entered the power saving mode, the user can still control the electronic device to enter by pressing the undock button on the electronic device. The removal procedure of the peripheral device. The removal button may be a hardware button or a software button disposed on the electronic device or the peripheral device, or may be a hardware button disposed on the connector of the peripheral device, and is not limited herein. When the user presses the detach button, the electronic device receives the trigger signal of the detach button, thereby waking up the electronic device, and sequentially enters the upper cover open state 208 and prompts to close the state 210 of the peripheral device related program. The user is prompted to close the program associated with the peripheral device on the electronic device, and enter the power saving mode after the program is turned off.
