Hello I have a macbook a1181 1.1, I do not have the installation disc and hd broke. I downloaded the snow leopard, installed and was very good, but I need win7. In bootcamp assistant it does not download the files for installing windows, I have downloaded several versions of bootcamp on the site, but all say it is not suitable for my version of the operating system. same so I installed all drivers, but when I suspend or hibernate, it returns without the brightness of the screen, to see the image of the dark background only. commands display brightness and other not worked, but are less important to me. thank immensely help.
