Compared with the prior art, the method for destroying hard disk in toll breakdown of notebook computer enclosure disclosed by the invention can be used for differently processing the hard disk of the notebook computer under different conditions: destroying data in the hard disk in the case of toll breakdown of the notebook computer enclosure, and not destroying the hard disk when opening the notebook computer enclosure to maintain the notebook computer, so that the security of the data in the hard disk of the notebook computer is effectively ensured to prevent the data in the notebook computer from being obtained by others.
Description
Technical field
The present invention relates to laptop hard security technology area, specifically a kind of notebook that realizes tolls breakdown the method that casing destroys hard disk.
Background technology
Along with the universal of notebook application and the raising to notebook data security, there is the notebook computer of some specific demands to require to realize the timely destruction of laptop hard data, prevent data in notebook from being obtained by other people.In recent years, the event that hard disk information is divulged a secret also emerged in an endless stream, and therefore, hardware destroy technology becomes the especially military active demand of individual and enterprise.
Disclosed patent application document: number of patent application is " CN201010595945.4 ".Name is called " destroy device of hard disk, CD and semiconductor storage body "; this document disclose that " destroy device of a kind of hard disk, CD and semiconductor storage body, it is destroyed mechanism, discharging mechanism, power source feeding mechanism by feed mechanism, pressure, automatically to be controlled and safety guard etc. forms.Adopt the destroy device of the hard disk of said structure, CD and semiconductor storage body, can destroy thoroughly overall device such as hard disk, CD and the semiconductor storage bodies put between pressure destruction mechanism's dynamic pressure head and static pressure head, reach the requirement that classified document is destroyed.This equipment can make concerning security matters personnel can in person destroy above-mentioned confidential document and carrier thereof whenever and wherever possible, and that avoids the contact of unrelated person to cause divulges a secret.This equipment have easy to use, safe and reliable, be easy to the features such as maintenance.The operation of equipment to environment also without any harm ".
Number of patent application is " CN201410819023.5 ".Name is called " method of the irreversible self-destruction of a kind of solid state hard disc Long-distance Control power down preventing ", this document disclose " method of the irreversible self-destruction of a kind of solid state hard disc Long-distance Control power down preventing; the method step is as follows: under normal operating conditions; solid state hard disc normally works, carries out storage by the SSD controller NANDFLASH controlled in external data and solid state hard disc and transmits; When needs perform solid state hard disc self-destruction, send self damaging order to the telecommunication control module on solid state hard disc by the mode of remote radio communication; Telecommunication control module sends destruction instruction to the self-destruction control module in solid state hard disc, and self-destruction control module performs self damaging order, realizes self-destruction to solid state hard disc; Afterwards, the self-destruction control module in solid state hard disc can feed back self-destruction status information, and remote control communication module feeds back self-destruction execution state information by telecommunication mode to control people again.The present invention controls solid state hard disc by telecommunication and performs self-destruction, avoids data maliciously to be altered, steal or leak under special, the harsh conditions such as without permission ".
Above-mentioned open file, although can destroy hard disk, the process for the hardware destroy of notebook computer can not carry out different disposal, when causing conventional maintenance according to different situations, also can cause the destruction of notebook computer hard disk, cause very large trouble to user.
summary of the invention
Technical assignment of the present invention is to provide a kind of notebook that realizes and tolls breakdown the method that casing destroys hard disk.
Technical assignment of the present invention realizes in the following manner, the method is: the EC chip be arranged on main board for notebook computer judges when whether the behavior of front opening Laptop case is for safeguarding notebook computer, if so, then EC chip does not go to destroy notebook computer hard disk; If not then EC chip can control motherboard power supply and powers to hard disk, and is dragged down by hardware destroy signal, realizes the destruction of hard disk.
The behavior of described maintenance notebook computer is the system software that user passes through to arrange in an operating system, send a signal to the EC chip on main board for notebook computer, now, take Laptop case apart, EC chip can judge it is carrying out notebook maintenance, and EC does not go to destroy hard disk.
It is realized by the Hall element installed on main board for notebook computer that described EC chip judges whether Laptop case is opened.
Described EC chip is embedded controller.
Described casing of opening safeguards that the step of notebook computer is as follows:
Before step 1) opens Laptop case, be introduced into operating system;
Step 2) operational system tool software;
Step 3) sends signal by System Uilities to EC chip, and notice EC chip needs to take Laptop case apart and safeguards notebook computer;
Now, EC chip does not detect Laptop case open mode to step 4);
Step 5) maintainer takes apart after Laptop case has been safeguarded and again enters operating system;
Step 6) operational system tool software sends signal to EC chip, and notice EC chip has been safeguarded, follow-up behavior of opening Laptop case belongs to the behavior of tolling breakdown.
The step that described EC chip destroys notebook computer hard disk is as follows:
Step 1) EC chip detection is arranged on the signal that the Hall element on main board for notebook computer transmits, and judges whether Laptop case is opened;
Step 2) EC chip judges that Laptop case is opened and is not maintenance behavior;
Step 3) EC chip controls motherboard power supply is powered to hard disk;
Hardware destroy signal drags down by step 4) EC chip, realizes the destruction of hard disk.
Compared to the prior art a kind of notebook that realizes of the present invention tolls breakdown the method for casing destruction hard disk, can carry out different disposal in varied situations, when Laptop case is forced open, realizes hard disc data and destroy laptop hard; In notebook maintenance process, open notebook casing then can not destroy hard disk, effectively ensure that the safety of notebook computer hard disc data, prevent data in notebook from being obtained by other people.
Accompanying drawing explanation
Accompanying drawing 1 be a kind of realize notebook toll breakdown casing destroy hard disk method open the FB(flow block) that casing safeguards notebook computer.
Accompanying drawing 2 is that a kind of notebook that realizes tolls breakdown the FB(flow block) that casing destroys the EC chip destruction notebook computer hard disk of the method for hard disk.
