查看wifi与蓝牙硬件开关，发现ideapad的硬件模块都是关闭的
rfkill list all
打开终端
输入
sudo gedit /etc/rc.local
写入以下内容 进行保存
#!/bin/sh -e # # rc.local # # This script is executed at the end of each multiuser runlevel. # Make sure that the script will "exit 0" on success or any other # value on error. # # In order to enable or disable this script just change the execution # bits. # # By default this script does nothing. echo "123" |sudo modprobe -r ideapad_laptop exit 0
为了保证重启生效，需要给予权限 终端输入
sudo chmod 777 /etc/rc.local
然后输入
reboot
