There was some disappointing information

Mi Problema

Apple buys batteries which seem to be designed to expand and create this problem. I had one laptop that went through three of them. It never happened in any of the PCs that I have ever owned.

Mi Solución

The only issue I had was the metal plate in the center that was under the trackpad. The adhesive from the battery pulled that up. You might have mentioned that.

Mi Consejo

A bit disappointed in the title and the way that the manual was set up.

The title was MacBook Pro 15" Retina Display Mid 2014 Battery Replacement

Not having done this before I thought 55 steps seemed a ridiculous amount of steps but thought "Well they are the experts, I should listen to them." After doing several completely unnecessary things I looked ahead and saw a note that said something to the effect that I skipped from Step 4 to Step 34.

Might have put IN BOLD LETTERS AT THE TOP --- IF ALL YOU NEED TO DO IS REPLACE THE BATTERIES THESE ARE THE ONLY STEPS YOU NEED TO DO.
