30 - 45 minutes
I couldn't get it to charge. Did a website search and found it was a typical problem. Contacted a major repair center and they said they wouldn't/ could not repair it. After watching the video on iFixit I decided to do myself.
The repair went very well. There was a step left out in the video I watched about removing some screws, but I figured that out.
I don't think this repair is for everybody. It was easier than I thought it would be but I am at the degreed Manufacturing Engineer.
