I have a Dell 15-7537 laptop install fedora 20 with kernel 3.14.8. But I can't power off my laptop using systemctl poweroff, I have tried openrc in gentoo, it couldn't either. Once I let systemctl power off my laptop, it will, but it actually do the reboot, I have to press power button on laptop or type halt in grub2, but it will cause the other reboot, after the second reboot, I could power off my laptop this time. But in the Windows 8.1, I don't need to do that, just click power off it would power off my laptop properly.
