So i have a MacBook with a broken displau, which has been broken for a couple of years and i kinda figured out i wanted to use it again, so can i get some help on how to use it? i hooked it up to a mac cinema HD Display and tried to press F7 as many other forums has suggested, but it did not work. So i ask for your help to bring back my macbook to life. Picture related, not mine but it is pretty much how it looks like.
