Hello, I would like to replace the rear housing behind my lcd. I think that is the correct term. Its the part that is on top when the macbook is closed where the apple logo lights up. I was wondering how hard is this to do? Also where would be a good place to buy the rear housing at ? The reason I want to replace this is because there are a few marks and a dent in the right back corner of they system. My machine is under apple care and apple saw the dent and didnt have a issue fixing the macbook pro, but I rather not have any future issues. Also is there anyway for me to tell how old my battery is ? Cycle count is 94 and condition is good. Can I check it by serial number on the apple site ect...? As always thank you for your help.!
