and S210, controlling a camera of the notebook computer to shoot a first image when the light sensor of the notebook computer detects that the ambient light intensity is smaller than a first threshold value and/or when the infrared distance sensor of the notebook computer detects that the distance between a display screen and a keyboard surface of the notebook computer is smaller than a second threshold value.
S220, judging whether the first image is matched with the preset image or not.
S230, if the first image is matched with the preset image, the notebook computer is in a closed state.
In this embodiment, the light sensor may be replaced by an infrared distance sensor, and when the infrared distance sensor of the notebook computer detects that the distance between the display screen and the keyboard surface of the notebook computer is smaller than the second threshold, the camera of the notebook computer is controlled to capture the first image. In addition, an infrared distance sensor can be added on the basis of the light sensor, and when the light sensor of the notebook computer detects that the ambient light intensity is smaller than a first threshold value and the infrared distance sensor detects that the distance between a display screen and a keyboard surface of the notebook computer is smaller than a second threshold value, a camera of the notebook computer is controlled to shoot a first image so as to assist in detecting the closing state of the notebook computer and accurately control the time point of shooting by the camera.

If the time when the ambient light intensity detected by the light sensor is less than the first threshold is greater than the first preset time, step S260 is executed, and if the time when the ambient light intensity detected by the light sensor is less than the first threshold is not greater than the first preset time, step S270 is executed.
S260, controlling the notebook computer to enter a dormant state.

In this embodiment, if the time that the light sensor detects that the ambient light intensity is less than the first threshold is less than the first preset time, that is, within 5 seconds, the notebook computer is turned on again, which indicates that the user may want to continue to use the notebook computer or want to perform other operations, for example, the shutdown operations in steps S271-S273, then it is determined whether the light sensor detects that the ambient light intensity is less than the first threshold in the second preset time, that is, it is determined whether the user wants to perform the secondary closing operation to start executing the shutdown operation.
If the light sensor detects that the ambient light intensity is not less than the first threshold value within the second preset time, it is indicated that the user may want to continue to use the notebook computer, and if the light sensor detects that the ambient light intensity is less than the first threshold value within the second preset time, the steps S210-S230 are repeatedly executed. If the second image shot for the second time is not matched with the preset image, the user is possibly misoperation, no action is executed, if the second image shot for the second time is still matched with the preset image, the notebook computer is controlled to pop up a first window for the user to select whether to shutdown or not, the first operation instruction of the user is received to control the notebook computer to shutdown, or the second operation instruction of the user is received to control the notebook computer to not shutdown and to close the first window.
The first window may display text content of "whether to confirm shutdown", the first operation instruction includes not performing any operation within a third preset time, clicking a left mouse button of the notebook computer, clicking a first key of the notebook computer, and clicking a first option in the first window through the mouse, the third preset time may be 3 seconds, the first key may be a "SPACE" key or an "ENTER" key on the notebook computer, and the first option may be a "yes" option in the first window. The second operation instruction includes clicking a right mouse button of the notebook computer, clicking a second key of the notebook computer, and clicking a second option in the first window through the mouse, wherein the second key may be an "ESC" key on the notebook computer, and the second option may be a "NO" option in the first window.
It should be further noted that, the shooting angle of the camera can be adjusted, optionally, when the angle of closing the display screen and the keyboard surface of the notebook computer is smaller than 45 degrees, the camera can shoot the first image which can be matched with the preset image, and at the moment, the user can easily observe the content of the first window and perform corresponding operation on the notebook computer. Preferably, the first preset time, the second preset time and the first threshold value can all enable the user to modify the first preset time, the second preset time and the first threshold value in the notebook computer according to own preference.
For example, if the user wants to quickly shut down, the user only needs to close the notebook computer to 45 degrees, then re-open the notebook computer within a first preset time, and finally completely close the notebook computer within a second preset time, and the notebook computer will automatically shut down within a third preset time.
According to the embodiment of the invention, the time when the ambient light intensity detected by the light sensor is smaller than the first threshold value is acquired; judging whether the time when the ambient light intensity detected by the light sensor is smaller than the first threshold value is longer than a first preset time or not; if the time that the ambient light intensity detected by the light sensor is smaller than the first threshold value is longer than the first preset time, controlling the notebook computer to enter a dormant state; if the time that the ambient light intensity detected by the light sensor is smaller than the first threshold value is not longer than the first preset time, judging whether the ambient light intensity detected by the light sensor is smaller than the first threshold value in the second preset time; if the ambient light intensity detected by the light sensor is smaller than the first threshold value within the second preset time, controlling a camera of the notebook computer to shoot a second image, and judging whether the second image is consistent with the preset image; if the second image is matched with the preset image, the notebook computer is controlled to enter a shutdown process, the problem that the control is not intelligent enough after the notebook computer is closed is solved, and the effect of intelligently controlling the notebook computer after the notebook computer is closed is achieved.
