LID is a magnetic switch on main board for notebook computer, and be responsible for the folding condition detecting notebook computer upper cover, be connected with EC, when folding lid, EC can both detect the state of notebook computer upper cover in real time.
In existing notebook computer, during closing lid, system enters standby or dormancy, arousal function of uncapping all has realization, but also do not realize closing lid automatic shutdown, the function of Auto Power On of uncapping.If there is a kind of method, can complete automatic shut-off function by the upper cover of shut of upper side in notebook computer when open state, then power on when opening upper cover start (cold start-up) function automatically, and notebook computer can be made like this to save electric energy, prolongs standby time, and facilitate use.
Summary of the invention
The technical matters that the present invention mainly solves is to provide a kind of notebook computer auto powering on/off apparatus, notebook computer can be made to save electric energy, prolongs standby time, also facilitate use simultaneously.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of notebook computer auto powering on/off apparatus, comprise south bridge, embedded controller, magnetic detector and permanent magnet, described permanent magnet is arranged on notebook upper cover and magnetic detector opposite position, and described south bridge is connected with embedded controller respectively with magnetic detector.
In a preferred embodiment of the present invention, described embedded controller is provided with the LPC interface and the GPIO interface being connected magnetic detector that connect south bridge.
For solving the problems of the technologies described above, another technical solution used in the present invention is: the control method providing a kind of notebook computer auto powering on/off apparatus, the folding lid state of described magnetic detector detection notebook computer upper cover informed embed formula controller, embedded controller controls start or shutdown action according to folding condition.
In a preferred embodiment of the present invention, when notebook computer upper cover closes:
By magnetic detector, A1, embedded controller detect that notebook computer is closing lid action;
B1, embedded controller arrange magnetic detector Status Flag, and produce SCI interrupt notification host computer system;
When C1, open state, host system response SCI event, by the ACPI command index in host computer system to inquiry magnetic detector Status Flag, if LID Status Flag equals 1, is closing lid state, calls shutdown command and perform shutdown process;
D1, embedded controller receive the shutdown command of host computer system, perform power down shutdown sequential;
F1, complete shutdown process.
In a preferred embodiment of the present invention, when notebook computer upper cover is opened:
By magnetic detector, A2, embedded controller detect that notebook computer is for action of uncapping;
B2, embedded controller remove magnetic detector Status Flag, and produce SCI interrupt notification host computer system;
When C2, off-mode, embedded controller performs start electrification reset sequential;
D2, complete boot action.
The invention has the beneficial effects as follows: notebook computer auto powering on/off apparatus of the present invention and control method thereof, under open state, when close imperial notebook computer upper cover time, system can normally be closed, and mainboard can all power down, except giving the power supply of embedded controller; In the power-offstate, when opening notebook computer upper cover, normally can start shooting by electrification reset, notebook computer can be made to save electric energy, prolongs standby time, also facilitate use simultaneously.
