我正在寻求有关运行 Windows 10 的 LenovoY700 的帮助。有些日子它工作正常，但其他日子我的键盘停止工作（甚至无法让笔记本电脑进入睡眠状态），它实际上是关闭的。我唯一能做的就是按住电源按钮几秒钟将其完全关闭。在此期间，系统和鼠标工作完全正常，我可以做所有事情，包括使用键盘，大约 5-15 分钟，然后我得到了 BSOD。我尝试分析 minidump 并更新 wifi 驱动器和英特尔集成显卡驱动程序，但那不是问题 :(

查看 dmp 可知设备“ VEN_8086&DEV_1901”（英特尔 (R) Xeon (R) E3 - 1200/1500 v5/第六代英特尔 (R) Core (TM) PCIe 控制器）导致崩溃：

因此笔记本电脑内部的设备导致了此问题。更新所有驱动程序（nVIDIA GPU、Intel HD、无线、LAN、声音）在 Power 中禁用 PCIe 总线的省电选项设置并观察会发生什么。
