I have an Acer Aspire Z3 600 and It comes with an internal battery. This makes things even more difficut for me because I have to take the battery out and power cycle and leave the battery out unless I do not plan on shutting my computer off. So upon restarting the screen means dark but the system is not off. So I have to manually unplug it to get it restarted. Email me please if you have any answers @ EDIT: email removed by Moderator
