5 - 10 minutes
My partners late 2009 Macbook started to fall apart all at once. The rubberised bottom peeled off, the batter stopped holding a charge and the fan failed.
I replaced the laptop with a new macbook and kept the old one until it failed completely which was the day after it was replaced.
A year later and I was going through all my old gear and found the Macbook and thought it would be a good exercise to fix it.
The repair took all of 35 mins with the new toolkit I purchased with the replacement parts.
Once everything was is place the Macbook, to my surprise, booted like it was brand new and is now my main 'nix box.
Just because it is broken it doesn't mean it can't be fixed ...and get the pro toolkit for the repair!!
