我的Y450按了WIN7后蓝牙，无线网卡都打不开了怎么办

Question

我的Y450按了WIN7后蓝牙，无线网卡，本机自带的SD读卡器也打不开了，驱动也下了就是没用，怎么办求解

Answer 1

你看看应该是服务被关闭了吧，估计是自己在优化的时候把这些服务都给关闭了 把下面的文件放在一个记事本里，然后改扩展名.bat 运行就可以开启服务，至于蓝牙和读卡器的我就不知道的是和型号有关，自己去找吧，这个就是可用开启无线服务 @echo off powercfg -h off sc config ALG start= DEMAND sc config AppMgmt start= DEMAND sc config AudioEndpointBuilder start= AUTO sc config Audiosrv start= AUTO sc config BFE start= AUTO sc config BITS start= AUTO sc config Browser start= AUTO sc config CertPropSvc start= DEMAND sc config clr_optimization_v2.0.50727_32 start= DEMAND sc config COMSysApp start= DEMAND sc config CryptSvc start= AUTO sc config Dhcp start= AUTO sc config Dnscache start= AUTO sc config dot3svc start= DEMAND sc config EapHost start= DEMAND sc config EventSystem start= AUTO sc config fdPHost start= DEMAND sc config FDResPub start= DEMAND sc config hidserv start= DEMAND sc config hkmsvc start= DEMAND sc config idsvc start= DEMAND sc config IKEEXT start= AUTO sc config IPBusEnum start= DEMAND sc config KeyIso start= DEMAND sc config LanmanServer start= AUTO sc config LanmanWorkstation start= AUTO sc config lltdsvc start= DEMAND sc config lmhosts start= AUTO sc config MMCSS start= AUTO sc config MpsSvc start= AUTO sc config msiserver start= DEMAND sc config napagent start= DEMAND sc config Netlogon start= DEMAND sc config Netman start= DEMAND sc config netprofm start= AUTO sc config NetTcpPortSharing start= DISABLED sc config NlaSvc start= AUTO sc config nsi start= AUTO sc config PlugPlay start= AUTO sc config ProfSvc start= AUTO sc config RasAuto start= DEMAND sc config RasMan start= DEMAND sc config RemoteAccess start= DISABLED sc config RpcLocator start= DEMAND sc config SamSs start= AUTO sc config SCardSvr start= DEMAND sc config SCPolicySvc start= DEMAND sc config SENS start= AUTO sc config SharedAccess start= DISABLED sc config ShellHWDetection start= AUTO sc config SNMPTRAP start= DEMAND sc config SSDPSRV start= DEMAND sc config SstpSvc start= DEMAND sc config SysMain start= AUTO sc config TapiSrv start= DEMAND sc config TBS start= AUTO sc config Themes start= AUTO sc config THREADORDER start= DEMAND sc config TrustedInstaller start= DEMAND sc config upnphost start= DEMAND sc config UxSms start= AUTO sc config vds start= DEMAND sc config W32Time start= AUTO sc config wcncsvc start= DEMAND sc config WcsPlugInService start= DEMAND sc config WinHttpAutoProxySvc start= DEMAND sc config Winmgmt start= AUTO sc config wmiApSrv start= DEMAND sc config WMPNetworkSvc start= DEMAND sc config wscsvc start= AUTO sc config wuauserv start= AUTO sc config wudfsvc start= DEMAND cls :wlansvc title 无线网卡服务设置 echo. echo. echo. echo 《无线网卡服务设置 控制台》 echo. echo. echo ╭───────────────────────────────╮ echo │ │ echo │ 本方法由cqbb制作 │ echo │ │ echo │ │ echo │ A. 本机有无线网卡 开启无线服务 │ echo │ │ echo │ B. 本机无无线网卡 关闭无线服务 │ echo │ │ echo │ │ echo │ │ echo │ │ echo ╰────────────────────────────────╯ echo.
