The invention discloses an automatic switching device for a laptop, which comprises a south bridge, an embedded controller, a magnetic detector and a permanent magnet, wherein the permanent magnet is arranged on a position of an upper cover of the laptop, corresponding to the magnetic detector, and the south bridge and the magnetic detector are respectively connected with the embedded controller. According to the mode and the automatic switching device of the laptop and the control method of the automatic switching device, which are disclosed by the invention, when the upper cover of the laptop is closed, the system can be normally shut down, and the mainboard except the embedded controller is entirely powered off; and in the power-off state, the laptop can be normally charged and reset when the upper cover of the laptop is started, so that the electric energy of the laptop can be saved, so that the stand-by time is prolonged, and meanwhile, the use of the laptop becomes convenient.
Description
technical field [0001] The invention relates to the field of computers, in particular to an automatic switching device and a control method for a notebook computer. Background technique [0002] Embedded controller (Embedded Controller, referred to as EC) is one of the important devices on the notebook computer, and its status is by no means inferior to the north and south bridges, and it is widely used in notebook computers. The embedded controller is responsible for the built-in keyboard of the laptop, touchpad (TOUCHPAD) processing, power-on reset sequence, power-off sequence, battery intelligent charge and discharge management, temperature monitoring, fan control and other tasks. The embedded controller plays an important role in the portable, intelligent and personalized design of the notebook computer. In a notebook computer, the embedded controller is always on, whether you are on or off, unless you completely remove the battery and power adapter. In the shutdown st...
