无线已被硬件开关禁用 Lenovo Y40

我最近买了一台联想 Y40 笔记本电脑，在安装了 ubuntu 14.04（也在实时 USB 中）后，无线功能无法使用。它说它被硬件开关禁用了，但是硬件开关不起作用（它的意图是进入飞行模式，但在 ubuntu 中按下它时没有任何反应）无线功能在 Windows 中可以工作，并且 BIOS 已启用它。我尝试重置 BIOS，但仍然不起作用。以下是一些命令输出

因为卸载 ideapad-laptop 显然会使无线功能正常工作，所以我们将其列入黑名单：

sudo -i
echo "blacklist ideapad-laptop"  >>  /etc/modprobe.d/blacklist.conf
modprobe -r ideapad-laptop
exit

一切已准备就绪。
