Power lock, it comprise lock collar, lock core and with the suitable key of described lock core, termination first power end of described power lock, described power lock is for controlling the power supply of described the first power end;
Electric pressure converter, the other end of power lock described in its input termination, analog power contact pin described in the output termination of described electric pressure converter, described electric pressure converter is for changing the voltage of described the first power end;
Key, one end ground connection, power supply start contact pin described in another termination of described key, between described key and described power supply start contact pin, be connected a second source end, the voltage of described second source end is converted by described the first power end, and described key is for controlling the power supply of described second source end.
Preferably, described controller is KBC chip.
Preferably, between described power lock and described the first power end, be in series with fuse.
Preferably, described second source end is connected between described key and described power supply start contact pin by a resistance.
Preferably, the input end of described electric pressure converter and output terminal are respectively and between ground, be parallel with some filter capacitors.
Preferably, the model of described electric pressure converter is AMS3107.
Preferably, the voltage of described the first power end is 19V.
Preferably, the voltage of described second source end is 3V.
Compared to prior art, the notebook computer that the utlity model has power lock can be in the time that notebook computer be idle, described the first power end can be disconnected by power lock, thereby disconnect the power supply to described controller, reach the object of power saving simultaneously, because described controller does not have Power supply, now press again key also without any reaction, system also cannot be opened.Of the present utility model simple in structure, can solve the defect of pressing key and can start computer system, effectively protect individual privacy or prevented stealing of classified papers.

Fig. 1 illustrates the external structure schematic diagram of the notebook computer for the utlity model has power lock.
Fig. 2 illustrates the internal circuit configuration schematic diagram of the notebook computer for the utlity model has power lock.
[embodiment]
In order to achieve the above object, refer to Fig. 1 and Fig. 2 illustrates, the notebook computer 10 of what the utility model provided have power lock, it comprises:
Controller 100, it has power supply start contact pin (PWRSW) 110 and analog power contact pin (AVCC) 120, described power supply start contact pin (PWRSW) 110 is for transmitting the starting-up signal of described notebook computer 10, and described analog power contact pin (AVCC) 120 is for transmitting the power supply signal of described notebook computer 10;
Electric pressure converter 400, its input end (INPUT) connects the other end of described power lock 200, the output terminal (OUTPUT) of described electric pressure converter 400 connects described analog power contact pin (AVCC) 120, and described electric pressure converter 400 is for changing the voltage of described the first power end (+PWR_VDDIN) 300;
Key 500, one end ground connection, power supply start contact pin (PWRSW) 110 described in another termination of described key 500, between described key 500 and described power supply start contact pin (PWRSW) 110, be connected a second source end (+VDD3_EC) 600, the voltage of described second source end (+VDD3_EC) 600 is converted by described the first power end (+PWR_VDDIN) 300, described key 500 is for controlling the power supply (the contiguous described power lock 200 of described key 500 is also located at the appearance of described notebook computer 10) of described second source end (+VDD3_EC) 600.
Wherein, described controller 100 is KBC chip.
Wherein, between described power lock 200 and described the first power end (+PWR_VDDIN) 300, be in series with fuse 310.
