当笔记本电脑出现开机黑屏的情况时，有可能是电量不足的问题，也有可能是系统故障的问题。总之，不同的原因有不同的解决方案，下面小编就跟大家分享七种解决笔记本开机黑屏的解决办法。
工具/原料：
系统版本：win10
品牌型号：联想小新air12
方法/步骤：
1、排查电量问题。
旧笔记本因为电池老化等原因，在开机时容易电量不足。我们连上电源进行充电，十分钟后重装开机就好了。
2、看是否进入睡眠模式。
电脑进入睡眠模式以后，长按笔记本电源键开机30s，通常情况下都能唤醒电脑。为了避免笔记本长时间待机系统睡死过去，我们可以打开“windows设置”-“系统”-“电源与睡眠”，设置“从不”进入睡眠。
3、排查电脑系统问题。
电脑若中了病毒，需要按开机键重启电脑，且在开机时不断按F8键，进入安全模式。在安全模式下，断网打开杀毒软件查杀病毒，然后对缺少的系统文件进行修复，再重新开机。
如果笔记本进入不了安全模式，那就试试用u盘重装系统吧!
4、检查显卡、内存、显示器、主板。
以上的方法试过以后，笔记本仍然是黑屏的状态，那么开始检查是不是内存或者显卡接触不良。(懂技术的朋友可以简单拆机看看，不懂的用户建议拿去专业维修店检修或者送去保修，以免弄坏笔记本)
将笔记本断电后取下内存条和显卡，清理插槽的尘埃，用橡皮小心擦拭显卡和内存的金手指，然后重新安插回去，再开机测试一下，一般都能解决!如果多次测试均无反应，那么可能是主板烧坏了，这种情况应该送到维修处进行维修。
5、检查显示器。
笔记本如果支持外接显示器的话，找一个没有损坏的显示器，连接到你的笔记本上。发觉电脑开机黑屏不再出现，那么造成黑屏的原因是显示器损坏。
总结：
1、排查电量问题。
2、看是否进入睡眠模式。
3、排查电脑系统问题。
4、检查显卡、内存、显示器、主板。
