简介
一般当电脑主板等出现故障问题的时候,我们可以考虑用主板诊断卡检测并进行维修。有网友想了解笔记本主板诊断卡怎么用,下面小编就教下大家笔记本主板诊断卡使用的方法。
工具/原料
系统版本:windows7系统
品牌型号:联想y570
方法
1、将电脑关机,把主板诊断卡,插在主板的PCI插槽;
2、然后开机,查看主板诊断卡显示的代码,通过代码可定位电脑故障;
3、当机器在加电启动的自检过程中出现无显故障时,先将电源供电断开,利用观察法,检查整机各部件的外观情况,是否有明显的外观不良和烧毁的痕迹;
4、如果没发现异常,再利用硬件最小系统法,将主板诊断卡插在ISA或PCI槽上(如主板带ISA槽,建议先选择ISA槽;如没有ISA槽,再选择PCI槽。选择PCI槽时最好是靠近中间的槽,因为该卡与少量主板有兼容性问题,使用第一个或最后一个PCI槽时可能引起“00”无显),连接好喇叭与主板SPEAKER插座的连线;
5、接通电源,启动最小系统。观察主板诊断卡左上角的两个发光管显示的代码,对照故障代码表,确认故障。此时也可通过指示灯状态、喇叭声音来判断故障;
6、如果在最小系统下没发现问题,再利用逐步添加法,逐一添加其他设备,观察诊断卡显示代码的情况,找出故障件。
总结
1、电脑关机,插入主板诊断卡;
2、开机观察主板诊断卡显示的代码定位电脑故障,并解决问题。
