Hi everybody, My Macbook Pro 15" Early 2011 has been hit by Radeongate (black screen), I immediately brough it to the Apple Store and they told me I could have it repaired for free, since Apple itself has recognized this defect on its notebooks even out of warranty. It seemed everything perfect, but now they called me saying that they cannot repair it anymore because I've replaced my original battery few months ago. This is true, but I replaced it when the Macbook was already out of warranty, and at that time I couldn't know about the defect on my notebook. What can I do? Are they right or should I insist? Thank you in advance for your answers.
