I'm coming to you live from my laptop. The Mac Air that I just fixed myself thanks to iFixIt.com -- I have an original Mac Air and it had an overheating issue from day one. Well, eventually the battery just blew up inside the computer and it, a. no longer worked and b. the battery wouldn't fit in the computer any longer.
At Fry's (where I bought the Mac Air eons ago and my other Macs, so they've gotten plenty of business out of me) but the young man told me about iFixIt.com and how it had videos on how to open and fix any Mac Product.
Well, it worked. I was given an estimate to fix the computer for $650 (but a new Mac Air without the overheating problem and a new battery style) is $999 so that didn't seem worth it. Well, it wasn't. I bought a new battery for $99 and put it in myself thanks to the videos on site. How cool is that?
I'm just so happy to have my baby back, so I had to brag a little.
