This was the hardest part for me. Be sure you flip the release flap up before removing or re-inserting.
My board was stuck to the bottom plastic. I had to gently release it by pushing the black plastic beneath the board down, while carefully moving the board upward.
Excellent walkthrough! This was my first ifixit repair and I was able to successfully replace my damaged magsafe board. The 64-Bit driver kit was the perfect companion to this project and the many more that will come in the future.
