I'm going to be waist-deep in keyboards

In one of my Pinebooks Pro, the battery puffed up and caused the bottom cover to push away and break the plastic where the screws attach to the palm case.  Or at least that's what I think caused the plastic to break.

So a month or two ago, I replaced the palm case.  Today I found out this one is broken already.  The hinges don't seem tighter than any of the other PBPs I have.
But I guess I'll loosen the hinges and replace the palm case again.
