MacBook Pro will only boot with top cover opened
I have a MacBook Pro 1.83GHz that will power on but the screen remains black. I repair computers so I disassemble it up to the point where I could remove the top cover. What I found is that if I ground the cover to the back of the body holding it almost verticle, and press the power button, it will boot fine. When I close the cover after booting it continues to work. If I try to boot with the cover down I only get the black screen. Im kind of stuck at this point, it seems as if there is a short somewhere but I will have to continue further. Anyone else having this issue? All suggestions will be appreciated.
Is this a good question?
