回答“MBP A1226 Logic Board last resort fix for nVidia video chip”The quilt saved my Macbook's life, and also mine... Just wrapped it powered on into a quilt, upside down for an hour. When I took the quilt out, the MB was extremely hot, I couldn't touch it's back. I let it cool down for almost another hour, and voilà!!! It is working again!!! Thanks Matthew! Thanks a lot!!!
