简介
本课程为远程主板维修培训实录，迅维笔记本、主板高级讲师--月饼老师讲解，台式机主板接口电路维修思路，值得一看，更多详细内容请见本课程。
接口电路检修：P/S2接口维修，老式键盘、鼠标接口，KBRST# ---IO发出给桥的，软复位，ctrl+del+alt送给---io--KBRST#---pch--初始化CPU。KB=键盘 MS=鼠标。
4x时钟分部，时钟芯片-100MSATA控制器的时钟-100MPCIE和DMI模块的时钟-14.318M基准时钟-48MUSB控制器的时钟-33MPCI模块时钟。
USB不能用的检修：检查接口5V供电，接地-数据线打值500左右-检查南桥48M时钟-检查南桥V5REF-SUS、VccUSBPLL供电-检查南桥周边精密电阻是否掉件-更换南桥。
无法识别网卡的维修：外观检查是否掉件-网卡供电（查芯片资料）-网卡时钟（有两个本身的25M晶振和总线33M、100M）-网卡复位（查芯片资料）-网卡的总线（网卡与南桥连接的线路）-换网卡芯片，MAC芯片，南桥；提示未插网线的维修：外观检查是否掉件-检测接口弹片，接口旁电阻是否烧坏-更换数据泵-换接口，网卡芯片。
