Now me and a friend have been sat here for two hours trying to sort this out scouring the web as we do. Firstly started friends mbp up and the screen didn't do anything but i can access his mac from screen share and use it. When checking system profiler it is saying he has an intel GMA 64 mb shared graphics card when the sr mbp was shipped with a geforce 8600 he has the same mbp as mine an thats what mine has. Can anyone figure out what to do to get his screen working again. Like i say i can access his mac and use via mine with screen share. It also seems like i cant use his track pad but i can click things. his keyboard and soundcard work too.
