用户在使用笔记本的过程中，会遇到按了开机键，笔记本电脑没有任何反应，也就是按开关键后指示灯不亮，听听风扇没有转动的声音，笔记本电脑没有一点反应。这，这，这，该怎么去解决呢？下面，小编就来跟大家分享解决笔记本开机没反应的经验。
笔记本电脑开机没有反应是一种比较常见的故障现象，导致这种故障发生的原因也是多方面的，需要进行仔细排查才能找到问题所在。有些时候我们在开启笔记本时会发现，笔记本开机没反应，怎么解决？下面，小编就给大家带来了解决笔记本开机没反应的操作了。
解决笔记本开机没反应
缘故一：电源适配器损坏
一般这个情况导致的笔记本开机没反应比较简单，可以直接替换，不过只限于同型号相同规格的电源。有一种情况需要特别注意，就是当你把电源适配器插入笔记本电源口的时候，电源适配器的指示灯灭掉，千万不要以为是电源本身的故障而反复去试，这是典型的主板严重短路。

如果用可调电源给笔记本加电的话，可调电源会自动保护，因为电流瞬间已达到5A以上，而笔记本电源不会自动保护，势必会造成更大范围的电子元器件损坏。
缘故二：笔记本主板故障
笔记本主板故障是笔记本开机没反应最常见的原因了，主要是由电源口坏、进水腐蚀、静电击穿、主板电路损坏等造成。电源口坏是主板故障里最简单的了，其他情况就要分别研究了。

1、进水腐蚀
它引起的笔记本开机没反应是最难修复的，如果处理方法及时正确可以将损失降到最低。如果只是自已简单的擦擦外表上的水再用吹风吹几下的话，即使当时能用，时间长了也会有各种各样的奇怪故障出现，维修起来也复杂的多。

2、静电击穿
这种多是自已在拆机做维护的时候，比如清洁风扇、添加内存时没有防静电措施，北方地区气候干燥，物品或多或少都会带有静电。笔记本中的集成电路对静电释放现象异常敏感，静电在瞬间释放的强效高压很有能够将集成电路内部的氧化膜击穿。

处理方法：
1、开机按F8不动到高级选项出现在松手，选“最近一次的正确配置”回车修复。

2、请开机按F8进入到安全模式中用系统自带的系统还原口还原到你没有出现这次故障的时候修复。

3、如果故障依旧，使用系统盘修复，打开命令提示符输入SFC /SCANNOW 回车，SFC和/之间有一个空格，插入原装系统盘修复系统，系统会自动对比修复的。

4、如果故障依旧，在BIOS中设置光驱为第一启动设备插入系统安装盘按R键选择“修复安装”
