The present invention provides a computer diagnosis method and diagnosis system, wherein, the method includes: step 1, firstly, a bios opens an infrared port of the computer under the course of the power on self test, the infrared port can work normally, step 2, the check point code generated in the course of the power on self test, is transmitted outwards by the infrared port; step 3, the infrared receiver receives the check point code and processing display. By utilizing the characteristics of the power on self test and the infrared transmission function, the invention receives and displaysthe power on the self test code of the display computer transmitted by an infrared transmission protocol by a common infrared receiver (such as a mobile phone with infrared function), the invention is generally used for most computers, having characteristics of convenient use and effectively controlling the diagnosis cost.
Description
A computer diagnosis method and diagnosis system technical field The invention relates to computer detection and diagnosis technology, in particular to a computer diagnosis method and diagnosis system for diagnosis by infrared rays. Background technique Mainboard diagnostic card, also called POST card (PowerOnSelfTst), its working principle is to use the detection results of the BIOS (Basic Input Output System) internal program in the mainboard to display the codes of the mainboard diagnostic card one by one. Code meaning quick look-up table just can know the place of computer fault very quickly, especially when PC (personal computer) machine can't boot operating system, black screen, loudspeaker not beeping, use main board diagnosis card to reflect its convenience more, get twice the result with half the effort. The BIOS on the motherboard will strictly test the circuit, memory, keyboard, video part, hard disk, floppy drive and other components of the system every time i...
