The keyboard had some water damage because my wife always uses it in the kitchen, she was really sad when her keyboard stopped working, so It was time for me to get into my DIY mode and fix it for her =)
The repair was easier than expected, the manual and the video from the site were easy to follow and they were of great help. I took the mac apart and put it back in no time =)
Keep your screws organized because THERE ARE A LOT OF SCREWS. I have some small containers (like the ones you use in the kitchen to put spices and stuff) and whenever I would take a part out (battery, speaker, fan) I would keep the screws separate from each other.
