导致电脑黑屏的原因有很多,显示的黑屏代码或界面也不同.最近有联想电脑的用户反映自己的笔记本电脑黑屏却开着机怎么办,不知道这种黑屏是什么原因造成.下面小编就给大家分享下可能的原因和修复电脑黑屏的方法.
一、笔记本主板的开机电路出现故障，比如时钟，复位，供电，MOS管等出现故障，都有可能引起无法开机，黑屏，I/O出现问题，也无法启动电脑，黑屏，等等吧，处理方法：送售后或者修理店修理主板。
二、就是笔记本的屏线折断或者接触不良，造成没有图像信号传送到屏幕上显示，也就是黑屏，处理方法：让维修笔记本的人重新插好屏线，或者更换屏线。
三、笔记本的电源适配器损坏，无法通电，或者笔记本的电池没有电了，从面导致无法开机，黑屏。处理方法：更换电源适配器，或者给电池充满电即可。
四、就是笔记本的内存和显卡被氧化，造成和内存槽或者显卡插槽接触不良，导致的开不了机，黑屏，处理方法：就是拨掉电源，打开笔记本的后盖，取出内存的卡槽，如果不是焊接在主板的独立显卡也取出卡槽，对准内存和显卡金手指的部位(也就是有铜片的地方)用橡皮擦来回擦上几下，把灰吹了，然后插回，盖好后盖，开机一般就OK了。
五、就是笔记本显卡的显存出现虚焊,主芯片性能下降,显卡BIOS出现错乱,控制电源IC出现问题,都会造成显卡无法正常工作,也就是显卡坏了,由于显卡坏了，自然就无法开机，黑屏了，处理方法：建义修理显卡,或者更换显卡。
以上就是联想笔记本电脑黑屏却开着机怎么恢复，希望能帮助到大家。
