人们常常说现在是互联网的时代,但小编个人觉得却是电脑的时代,现在缺少电脑就无法正常的工作以及生活,如果充电的时候发现电源适配器坏了,大家肯定一脸懵逼,下面是小编整理的电脑电源适配器坏了维修方法,仅供大家参考。
工具/原料:
系统版本:win7系统
品牌型号:联想扬天M51-80A-ISE
方法/步骤:
电脑电源适配器坏了维修方法:
1、如果原装适配器有问题的话,无法维修或来不及维修,可以先使用其他适配器替代,只要输出电压以及功率大致相当就可以啦。笔记本电脑内部还有稳压电路撑着,不要大家也不用太过于担心输出电压不匹配的问题。而在维修的时候,第一步需要我们做的就是工具准备。我们需要万用表、螺丝刀、焊接工具等等。
2、电源适配器中有四个塑料帽,大家尽可能不要破坏适配器外壳,外壳破坏后,会出现电磁辐射加强等等故障问题,影响机器稳定。如果外壳破坏的话,尽量修补。拆卸过程如果外置电源不供电,这时可以插上电池试试,如果机器可以正常启动的话,就有可能是电源线或适配器有问题。打开外观,打开屏蔽层之后,最好是首先检查焊脚,肉眼观察,电路时断时续,通常是接触不良。再用万用表检测,查明电源线是否有问题,以简化维修难度。
3、检查电容电阻电感是否有故障问题,如果电容出现鼓包,最好及时更换,避免留下隐患。
总结:
以上就是电脑电源适配器坏了维修方法啦,希望对大家有所帮助。
