@tetzel , johann, Try hooking up an external monitor, if external monitor works probable laptop display issue, corrupt driver, bad connection on ribbon cable, bad display. If external monitor not working could be graphics card issue. Below link tells how to hook up external monitor to help trouble shoot your laptop, the 3rd link and other Acer forums on the net, addressing Blank/black screen talk about the Bios becomes corrupt and needing addressed. Good luck.
