10 - 30 minutos
I had my Mac charging, and I left it sitting on the sofa. It fell off, and landed on the charging side. It pushed the Magsafe board in, and crushed it... Oh no!
Fantastic. I am lucky enough to have a wonderful person in my life, who is smart. He replaced the board in about 15 minutes.
Make sure you have the proper tools. Macs have weird screws.
