However, the resulting puter motherboard failure of many puter enthusiasts are tired of the brain. At the same time, board maintenance technology as a gradual warming of the technology on the basis of which started as a puter motherboard repair as the beginning of a new round of the popular technology, first of all main board maintenance can be divided into: maintenance boot circuit, CPU without the main power supply Circuit maintenance, repair circuit clock, reset circuit maintenance, repair, and other interface types of failure in five parts. In this paper, the board is among the most basic maintenance is essential for the maintenance of the circuit that is maintenanceboot circuit. This article first of what is the motherboard? On the classification board to form the specific analysis, our board will help to better understand the following analysis on the main board and maintenance. Then, on the main board on the role of mon ponents, good or bad judgments and the replacement of the principle of further analysis will help us in the process of fault repair and replacement of the judge. Next on the circuit board boot, and maintenance of the principle of specific examples of graphic analysis, so we understand what is the boot circuit board? It is how, as well as maintenance work which we should pay attention to what? Its maintenance work flow is what? These steps can be defined in their daily lives so that we can resolve some of the main board appeared in the mon fault in our study, work full use of various puter functions for our services. The main thesis describes the background of this issue, boot the puter circuit analysis and specific maintenance process, focusing on analysis of the boot circuit classification, position, working principle, as well as examples of failure of maintenance. Key words: maintenance of the Main Board, the boot circuit, the circuit clock, reset circuit, faulttype interface 目 錄 摘 要 I Abstract П 緒 論 IV 第一章 主板的發(fā)展簡介 1 主板的發(fā)展歷程 1
