I have a Rev A Macbook, bought in September 2006. I bought the extended Applecare warranty so I'm covered until September 2009. It's been through a bunch of repairs... gotten a new logic board, new battery, 3 new top cases, and it's been in a few times for the inverter to fix the screen flickering issue. On December 18 I dropped off my Macbook at the Apple Store, because the top case chipped again, and the screen flickering issue had been getting worse. It happens mainly when I am on battery power, and since I am using it in college, I see the screen flicker all the time. I just got my Macbook back from the Genius Bar last night, to get a 3rd top case and to fix the flickering issue. I got it back with a new top case, but the flickering was still there. I called Applecare and I was told that the inverter was not even replaced by the genius, despite the Genius telling me that "this was a known issue with the Macbook". I wonder why it took 3 business days to replace the top case? The person from Applecare said the only thing I could do was bring it to an Apple Store to have it replaced again. Should I just humor them and bring it back to the Apple Store again? Or is there some other course of action I can take to request a replacement? This is really frustrating, because I don't want to have to start the semester without a computer, and I'm getting annoyed with not having my computer for days at a time, and not having the issue fixed.
