Method and system for limiting the lifespan of a computer

Abstract

The invention provides a computer expiration date limiting method, comprising the following steps: (S11) acquiring real-time clock information and saving the current real-time clock information into current system date variables; (S12) acquiring a current reference date and determining whether the current system date is consistent with the current reference date or not; if the current system date is consistent with the current reference date, information in the current system date variables is saved into reference date variables; if the current system date is not consistent with the current reference date, step S14 is performed; (S13) determining whether the current reference date reaches an expiration date or not; if the current reference date reaches the expiration date, a locked shutdown state is enabled; (S14) calculating user modifications according to the current system date and the current reference date and updating the expiration date; and (S15) saving information in the current system date into the reference date variables and returning to step S13 to continue the operation. The invention also provides a computer expiration date limiting system. The invention has the advantages that the expiration date is limited more effectively and safely, and effects of user experience are not affected.

Description

technical field [0001] The invention belongs to the field of computers, and in particular relates to a method and a system for limiting the lifespan of a computer. Background technique [0002] BIOS (Basic Input and Output System, referred to as Basic Input and Output System) refers to a ROM chip integrated on the motherboard, which stores the most important basic input and output programs of the microcomputer system, system information settings, power-on self-test programs and system startup bootstrap Programs, etc.; it is responsible for initializing and testing the various hardware of the system when the computer is turned on, so as to ensure that the system can work normally. BIOS is also a set of programs used to link computer hardware and software programs, which provide the lowest and most direct hardware control for the computer. [0003] When the computer is turned on, the BIOS will first perform a self-test (PowerOnSelfTest, POST) on the computer, that is, to dete...

However, this method may be cracked by the user, and then modify the system time to make the timing invalid; at the same time, restricting the time modification will limit the user's freedom of use, affect the user's experience, and even be reported as a defect in product design.

[0008] In addition, the setting of the service life can also use the third-party background running software timing method, but once the operating system is replaced, the timing will also be invalid; and once the background software is discovered and uninstalled by the user, it will cause the timing to fail
