This is a very easy operation. Yes, you can do it in a few less steps, but I chose to do it EXACTLY like the instructions, that way I had the least amount of opportunity to break anything. Yes, potentially removing so many items you have an opportunity to break something, but in my opinion, it’s worth it. At least you learn where the components are and what they look like that way. Very good guide. I’m not sure of their other guides, but if they are like this one, it definitely saves $100 bucks in labor plus $199 for the battery at an Apple Store!

When you are at this step and before you put the new battery in, take the time to clean your computer really well. You will be surprised how much dust/dirt and even pet hairs have gotten into your computer. After I removed the battery, I use a little more of the acetone to clean the bays up and after it dried, I used a tiny bit of Isopropyl Alcohol to make sure there was a good clean area for the new bonding. Make sure you clean the fans. Don’t use a toothbrush or anything like that. If your have a Lowes or Home Depot, you can buy a shop vac attachment kit for about $20, it’s well worth it. Don’t use that air in a can crap, it will put moisture on circuits. Take your time, it’s not a hard task to do everything, just use a little patience.

Be very careful on this step. If you aren’t you can snap the plastic on the corners where the screws go in. Remember to go slowly when spinning the screws back in, it doesn’t take gorilla torque to tighten them, just take it easy!
