I am an IT person, know computers well so I don't know why this would surprise me but this week my iPad fell off of my desk and the screen did just as in the original post. I couldn't even do my back up because I have a password on my iPad so I couldn't type that in. I had already made an appointment with the Genius Bar (2 hours one way away from me!!!) and do not have Apple care so was very upset and I read this post by alanfromnewtownards. I would have never in a million years dreamt this would work but I had absolutely nothing to lose so I did it. The first time, nothing but the I started patting all around the back while upside down then hit the menu button and OMG I almost peed my pants from laughing so hard that this is what it took to fix my sweet iPad. I love my Mac toys almost as much as my children and that's saying A LOT!!!! So, alanfromnewtownards, I cannot thank you enough! You are amazing and anyone who questions this unorthodoxed approach to iPad repair can either keep their broken iPad or pay large sums of money to get theirs fixed.
THANK YOU, THANK YOU, THANK YOU, THANK YOU!!!!!!!!!
