Got a MBP mid 2009 that needs a new battery and can't seem to find any genuine batteries on the market so I cannot fix it myself... So I'll have to go to the geniuses and get this replaced! BUT I'm worried about them refusing to replace the battery since I have done a few things on my own in there, I have replaced the track pad and upgraded the memory, resulting in the pentalobe screws are a bit messed up though... Hopefully they are still working Warranty is long gone for the computer, so that will not be an issue for me. Will they... ...be happy to replace it? ...be angry and replace it? or ...refuse to replace it?
