联想 G500 蓝牙停止工作

联想 G500 蓝牙停止工作

我有一台联想 G500 笔记本电脑。它的操作系统是 Windows 8。我买这台笔记本电脑时,一切都运行良好。但一个星期以来,蓝牙一直无法使用。我在“设备管理器”中查找,但找不到蓝牙。

为什么我找不到蓝牙?如何才能让蓝牙再次工作?


更新 :

我无法通过 Charms 菜单 -> 设置 -> 更改 PC 设置 -> 无线来打开蓝牙。但我可以从那里打开 WiFi。

另外,我在“services.msc”中搜索,发现其中有 3 个蓝牙相关服务,其中 2 个正在运行。

 Check your mouse about paring mode or connect button underneath, (Some mouse has a trigger to pair)
Make sure that the Bluetooth services are started

       Press Windows button +R
