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.
