Abstract

The invention discloses a computer power-off protection system, which relates to the technical field of computers, and comprises: a log generation module I which communicates with a data protection control module and is used for recording all data information to be read and written by a hard disk module when power off occurs; a log generation module II which communicates with the data protection control module and is used for recording read-write records of all data information to be read and written under the power supply of the energy storage capacitor; a data protection control module whihch is used for controlling the read-write work of the hard disk module until the hard disk magnetic head is reset and executing a power-off program. The beneficial effects of the invention are that:during power failure of computer, power supply is continuously kept through the energy storage capacitor, and after the computer is normally started, results of the log generation module I and the log generation module II are sent to the computer processor, so that a user knows which data is read and written completely after power failure and which data is not read and written or stopped, and the user knows the data conveniently.

Description

technical field

[0001] The invention relates to the technical field of computers, in particular to a computer power-off protection system and method. Background technique

[0002] The emergence and development of computers is one of the most important scientific and technological achievements in the 20th century. Computers have penetrated into various fields of the national economy and society, greatly changing people's lifestyles and working methods, and becoming a huge productive force to promote social development. At the same time, with the development of modern technology, new types of computers such as notebook computers and all-in-one computers have also appeared. But now most desktop computers use household power as the main power supply method, and there is a problem: when there is a sudden power failure, the desktop computer will stop working, and some important data in our hard disk will often be lost because of this; Electricity will make the read-write head of ...
