This time, however, it's a slightly different game because of the fragility of the Coconut shell. I really don't want to take the thing apart any more than is necessary.

Hint: use rubber bands to hold the case halves together when testing. Then you don't have to put undue stress on the screw posts, and you're not really putting it together. This is what I do when I am testing or updating boards before shipping them. One around the top of the case to get pressure on the battery contacts and one over the keyboard to get pressure on the CPU contacts. I use fat rubber bands from walmart that are big enough to wrap three times around the case.
