So Apple was wonderful enough to replace my "macbook crack" out of wty since it is a known issue and I am truly thankful for that. Nice folks. While it was there they stuck a new bottom case on and some other internal goodies were changed out for whatever reason. My Superdrive always stuck when you put a CD in, but I never mentioned it as it worked fine an it didn't come with the book anyway, it was installed at a later date. Well it came back looking all spiffy and working excellent. Nice new bottom case and top cover, keyboard, etc... looks like a brand new book. No problem, right? Ehhhhhh. hey guys..... where did my superdrive go? Apparently the tech figured out my superdrive was sticky and decided to replace it also.......... with a combo drive. Since this book came with a combo drive they simply looked at what the factory specs were and grabbed the proper part number. Well, not so proper part number. My agent is getting it fixed right now so it is not going to be an issue, but I have to be without my book again and I run an e-business so the last 3 days have been heck without it. The next three aren't going to be any better. I just want to make a little note to persons that have added on parts to their books to make a big huge sticky note and tape it to the laptop if you send it in for Applecare that you have upgraded parts in your book. If not, you might not get them back! Thankfully I have a great agent helping me and it will get resolved, albeit a bit more unfortunate downtime.
