Chosen Solution
During the battery change procedure, which went well for the most part, I broke the “small antenna cable” identified in section 17. Didn’t notice until reassembly. Since it is not the GPS nor the WI-FI antenna, I’m unclear exactly what I will find inoperative once I finish. Is a replacement available? (I was confused by the difference in picture between the Wi-Fi model and mine. Oh well.)
It is the Right Cellular Antenna. With a damaged antenna, you will have less (or no) cellular sugnal.
