It is not connect with hard disk, warning device and plate level power supply；The plate level power supply is also connected with lithium battery.
It is two software programs that notebook base control and hard disk, which destroy control, realizes different functions respectively；The pen
Remember that this base control includes the switching on and shutting down of mainboard, the electrifying timing sequence of power supply, the control of ACPI power supply, Keyboard Control and touch tablet control
System；
Preferred according to the present invention, the EC control chip is the IT8528E chip of ITE company；The warning device is
Buzzer.The present invention hardly needs other IC hardware, by soft using EC chip as hardware essential in notebook
Whether the screw of part and mechanical switch detection notebook is by illegal disassembly realization notebook tamper.
A kind of working method of above-mentioned notebook detatching-proof system, including steps are as follows：
1) when the screw tightens, screw resists mechanical switch, and mechanical switch is in closed state；Corresponding GPIO is low
Level state；
2) when any one screw is disassembled, mechanical switch is in an off state, and corresponding GPIO is become by low level state
For high level state；
3) high level triggering warning device alarm；
4) after dismantling 1 screw triggering alarm, if continuing to dismantle any other screw, and disassembly sequence and setting sequence
It is inconsistent, then it triggers the hard disk and destroys control realization hard disk destruction, ensure data safety.
Preferred according to the present invention, the level state of the GPIO controls chip by EC and detects to obtain.
Beneficial effects of the present invention are：
1. the notebook detatching-proof system of the present invention based on EC, only real by the necessary EC of notebook and mechanical switch
Existing notebook tamper and guarantor and data destroying ensure that the hard disc data of user is not stolen by illegal disassembly；The simple cost of system
It is cheap.
