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

If the time that 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 that 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.
And S260, 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 longer than the first preset time, namely within 5 seconds, the notebook computer is not turned on again, it indicates that the user does not use the notebook computer temporarily, and then the notebook computer can be controlled to enter a sleep state to ensure the endurance. The method ends by this execution until the user reuses the notebook computer.

If the light sensor detects that the ambient light intensity is not less than the first threshold within the second preset time, it indicates that the user may want to continue using the notebook computer, and if the light sensor detects that the ambient light intensity is less than the first threshold within the second preset time, steps S210-S230 are repeatedly performed. If the second image shot for the second time is not matched with the preset image, the fact that the user is possible to operate by mistake is indicated, 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 the notebook computer is powered off, the notebook computer is controlled to be powered off by receiving a first operation instruction of the user, or the notebook computer is controlled not to be powered off and the first window is closed by receiving a second operation instruction of the user.
The first window can display the text of 'whether to confirm shutdown', the first operation instruction includes that no operation is performed within a third preset time, a left mouse button of the notebook computer is clicked, a first button of the notebook computer is clicked, and a first option in the first window is clicked through the mouse, the third preset time can be 3 seconds, the first button can be a 'SPACE' button or an 'ENTER' button on the notebook computer, and the first option can be a 'YES' option in the first window. The second operation instruction comprises clicking a right mouse button of the notebook computer, clicking a second button of the notebook computer and clicking a second option in the first window through the mouse, wherein the second button can be an 'ESC' button on the notebook computer, and the second option can be a 'NO' option in the first window.
It should be further noted that the shooting angle of the camera may be adjustable, optionally, when the angle of the display screen and the keyboard cover of the notebook computer is smaller than 45 degrees, the camera may shoot a first image that matches with the preset image, and at this time, the user may also easily observe the content of the first window and perform corresponding operations on the notebook computer. Preferably, the first preset time, the second preset time and the first threshold value can be modified in the notebook computer according to the preference of the user.
For example, if the user wants to quickly shut down the computer, the user only needs to close the notebook computer to 45 degrees, then reopen the notebook computer within a first preset time, and finally completely close the notebook computer within a second preset time, so that the notebook computer can be automatically shut down within a third preset time.
According to the embodiment of the invention, the time that the ambient light intensity detected by the light sensor is less than the first threshold value is obtained; judging whether the time that 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 sleep 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 within 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 matched 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 notebook computer is not intelligent enough after being closed is solved, and the effect of intelligently controlling the closed notebook computer is achieved.
