LID is a magnetic switch on the main board for notebook computer, is responsible for detecting the folding condition of notebook computer upper cover, is connected with EC, and when folding was covered, EC can both detect the state of notebook computer upper cover in real time.
In existing notebook computer, the system of closing when covering gets into standby or dormancy, the arousal function of uncapping all has realization, but does not also realize closing lid shutdown automatically, the function of the Auto Power On of uncapping.If a kind of method is arranged; Can when open state, accomplish shutdown function automatically by the loam cake of shut of upper side in notebook computer, start (cold start-up) function that when opening loam cake, powers on automatically then can make notebook computer save electric energy like this; Prolongs standby time, and made things convenient for use.
Summary of the invention
The technical matters that the present invention mainly solves provides a kind of notebook computer auto powering on/off apparatus, can make notebook computer save electric energy, and prolongs standby time has also made things convenient for use simultaneously.
For solving the problems of the technologies described above; The technical scheme that the present invention adopts is: a kind of notebook computer auto powering on/off apparatus is provided; Comprise south bridge, embedded controller, magnetic detector and permanent magnet; Described permanent magnet is arranged on notebook loam cake and magnetic detector opposite position, and described south bridge is connected with embedded controller respectively with magnetic detector.
In preferred embodiment of the present invention, described embedded controller is provided with the LPC interface and the GPIO interface that is connected magnetic detector that connects south bridge.
For solving the problems of the technologies described above; Another technical scheme that the present invention adopts is: the control method that a kind of notebook computer auto powering on/off apparatus is provided; Described magnetic detector is surveyed the folding lid state of notebook computer upper cover and is notified embedded controller, and embedded controller is controlled start or shutdown action according to folding condition.
In preferred embodiment of the present invention, when notebook computer upper cover closes:
A1, embedded controller detect notebook computer for closing the lid action through magnetic detector;
B1, embedded controller are provided with the magnetic detector Status Flag, and produce SCI interrupt notification host computer system;
When C1, open state, host system response SCI incident to inquiry magnetic detector Status Flag, if the LID Status Flag equals 1, is the state of lid that closes through the ACPI command index in the host computer system, calls shutdown command and carries out shutdown process;
D1, embedded controller are received the shutdown command of host computer system, carry out power down shutdown sequential;
F1, completion shutdown process.
In preferred embodiment of the present invention, when notebook computer upper cover is opened:
A2, embedded controller detect notebook computer through magnetic detector and are the action of uncapping;
B2, embedded controller are removed the magnetic detector Status Flag, and produce SCI interrupt notification host computer system;
When C2, off-mode, embedded controller is carried out start electrification reset sequential;
D2, completion 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 closing imperial notebook computer upper cover, system can normally close; And all power down of mainboard are except giving the power supply of embedded controller; Under off-mode, when opening notebook computer upper cover, normally electrification reset start can make notebook computer save electric energy, and prolongs standby time has also made things convenient for use simultaneously.
