Fig. 2 shows hardware circuit diagram when lock core does not insert lockhole.
Detailed description of the invention
With reference to the accompanying drawings the specific embodiment of the present invention is described further:
Embodiment 1
As shown in Figure 1, the device according to embodiments of the present invention comprises lock core 10, lockhole 20, spring structure 30, EC40 (EC, embeded controller, embedded controller), wherein spring structure 30 comprises spring leaf 301, spring 302, contactor 303.
Lock core 10 can promote spring leaf 301 by inserting lockhole 20, and spring leaf 301 can control circuit switch 303 closed by extrusion spring 302, and the closure state of contactor 303 can the action of control EC40.
As shown in Figure 2, when lock core 10 does not insert lockhole 20, spring structure 30 is failure to actuate, and contactor 303 disconnects, and the off-state of contactor 303 can the action of control EC40.
Lock core 10 for inserting lockhole 20, extrusion spring structure 30;
Lockhole 20 is for providing insertion passage for lock core 10;
Spring structure 30 comprises spring leaf 301, spring 302 and contactor 303, when inserting lockhole 20 for lock core 10, lock core 10 promotes spring leaf 301 extrusion spring 302, spring 302 pull switch makes contactor 303 close, mainboard special circuit is connected, and when not inserting lockhole 20 for lock core 10, spring structure 30 is failure to actuate, contactor 303 is disconnected, and mainboard special circuit is not switched on;
EC40 is used for when contactor 303 closes, at computer just in a situation of use where, computer for controlling enables BIOS harddisk password and OS login password, if BIOS harddisk password and OS login password do not exist, then control OS sends information, prompting user arranges BIOS harddisk password and OS login password, when start-up simulation machine, if there is no BIOS harddisk password, then control OS sends information, prompting user arranges BIOS harddisk password, if there is BIOS harddisk password, control to start BIOS harddisk password, and control OS sends information, after prompting user inputs BIOS harddisk password, computer just can continue to be used, when contactor disconnects, at computer just in a situation of use where, control OS sends information, whether prompting user's BIOS harddisk password and OS login password are removed, when start-up simulation machine, if there is BIOS harddisk password, control to start BIOS harddisk password, and control OS sends information, after prompting user inputs password, computer just can continue to be used, after Password Input, control OS sends information, whether prompting user BIOS harddisk password is removed, if there is no BIOS harddisk password, EC40 is failure to actuate.
In computer run process, lock core 10 inserts lockhole 20, promote spring leaf 301 extrusion spring 302, promote contactor 303 after spring 302 is squeezed to close, after EC40 is subject to the triggering of contactor 303, computer for controlling starts BIOS harddisk password and OS login password, if BIOS harddisk password and OS login password do not exist, then control OS sends information, and prompting user arranges BIOS harddisk password and OS login password.
In the process of start-up simulation machine, during BIOS self-inspection, detect that contactor 303 closes, mainboard special circuit is connected, and after EC40 is subject to the triggering of contactor 303, computer for controlling starts BIOS harddisk password, and control OS sends information, after prompting user inputs BIOS harddisk password, computer just can continue to be used, if do not have BIOS harddisk password, then control OS sends information, and prompting user arranges BIOS harddisk password.
In computer run process, lock core 10 is extracted from lockhole 20, spring structure 30 is made to return to state when lock core 10 does not insert lockhole 20, contactor 303 disconnects, mainboard special circuit is not switched on, after EC40 is subject to the triggering of contactor 303, control OS sends information, and whether prompting user's BIOS harddisk password and OS login password are removed.
In the process of start-up simulation machine, during BIOS self-inspection, detect that contactor 303 disconnects, mainboard special circuit access failure, EC40 controls after being subject to the triggering of contactor 303 to start BIOS harddisk password, and control OS sends information, and after prompting user inputs password, computer just can continue to be used, after Password Input, control OS sends information, and whether prompting user BIOS harddisk password is removed, if do not have BIOS harddisk password, EC40 is failure to actuate, and user directly can use computer.
