笔记本电脑清灰打硅脂后,开机一直黑屏,如何破?
2022-06-12 18:28:00 【叶庭云】
毕业准备收拾东西回家了,想着把我的笔记本电脑送去清灰打硅脂,保养一下,期望我的电脑研究生也能再挺两年emmm。结果学校里手机电脑维修店里那大哥给我拆开清灰打硅脂后,我去取的时候检查发现,开机一直黑屏,让他看看,背光键盘、鼠标外接键盘、电源口都有光,有反应,风扇也在转。
网上看别人的经验分享,可能是如下原因:
- 插口出现弯针。
- 内存可能没有插好,这个比较常见。
- 螺丝可能拧错,常见的是长螺丝弄到短螺丝的位置弄穿主板。
- 可能拆机导致风扇和屏幕线接触不良所导致的。笔记本排线可能没有正确连接,重新检查连接排线。
- 如果电源指示灯亮,散热风扇口有风,但显示器依然黑屏,这种情况多数是笔记本内部有线路故障或硬件故障,比如笔记本内部内存条松动,显卡故障,以及显示面板故障等。此时建议大家用电脑外置的显示器,就是一般台式机的显示器,连接到笔记本外接显示接口,如果显示一切正常,基本上排除了主板和显卡损坏的可能。如不正常说明主板或者显卡有问题。另外,内存松动也有可能造成开机黑屏。
这种情况一般就是你安装硬件不到位导致的,重新拆机,然后将排线和硬件都拔插一下,再次开机看看吧,这个如果没有带电拆机的话,一般不会损坏硬件的
- 主板没有安装好,也就是里边有些线路没有连接好,因为你外接键盘没有任何反应,所以可以断定 USB 接口不通电。
- 主板受损,或者显示器排线没有安装好。主板受损和排线安装不好都会造成上述现象。
那大哥又拆开检查了半天,也不知道是哪儿问题,说是显示屏出问题了,换个显示屏要 600,让人送了个显示屏过来,换上开机也还是不行,啊这。。。然后他也不会了,说送去给另一个师傅看,第二天说是主板问题,修主板是 350。。。回去跟我室友讲起都说我被坑了,就这样,我笔记本电脑清灰打硅脂而已,主板就出问题了,可能就是学生的钱好赚吧,罢了罢了,溜了溜了。
