A complete teardown like this is very risky unless you have a high level of confidence and experience with doing teardowns on integrated laptops, which often have narrower clearances and more fragile parts than older, bulkier style laptops. As you can see below someone who is Apple Certified and Comptia A+ has expressed having issues with this. In my opinion taking the laptop apart like this for this battery replacement is the last option. The first, if you have little experience is to have someone else do it. The second, if you have confidence with isolating the battery compartment safely for adhesive removal is to follow only the steps required for removing the battery itself, and the third is to follow this guide.

The riskiness level of this approach is way too high relative to the basic requirements of replacing the battery. This is pretty much a teardown which is not necessary for battery replacement. Yes, you will need to use some type of adhesive removal which is risky near the other components of the computer, but way less risky than this complete teardown.
