Trackpad not clicking/stuck down
I recently did a full rebuild of my MBP, which had been damaged. New top and bottom cases, new display, new battery. I tested the trackpad mechanism before reassembly and it seemed to click fine. Once it's all back together, though, the trackpad is stuck. It will still physically click with some substantial force, but it seems to be stuck down as it's prone to perma-clicking and dragging random things around. Squeezing the case assembly to the side of the trackpad seems to be a semi-reliable way to get a click.
Since the battery has been replaced, I know it's not bulged, so what else could be the culprit here? I know how difficult (read: very) it is to remove the battery again to troubleshoot so I'd really, really prefer not to. I'm considering using a plastic opening tool around the edge to try to jimmy it upward a little, but I'm wary since it's glass and I don't want to replace it.
I popped it open just out of curiosity and lifted the center battery modules just enough to free them and checked it. It seems to click okay. The battery is confirmed not bulged, though, and when I put it back together it doesn't click again. What am I doing wrong?
Is this a good question?
