Trackpad Set Screw immovable
The Set Screw under my trackpad is immovable. I have not dremelled it, or drilled into it, because of its position on the case; I fear damage to the case. I am replacing my trackpad since there is a slight tear in the ribbon that attaches it to the motherboard, hence it is acting as if there is no trackpad there, or no sensor there, and the fan is going full steam.
Back to the set screw:
I have used WD-40, and I fear stripping the screw if I use my torx screwdriver anymore than I already have. I am not sure what happened to the screw. The battery did expand above it, and I just received a replacement battery from iFixit. No liquids were spilled into the computer etc.
The trackpad not clicking AT ALL, after I replaced my battery, is what led me to discover the status of the set screw. If drilling or dremelling is the answer, could that kind of answer be super specific, since I have not understood others that I have read.
I also wonder whether I just have to get a new case, because of the screw.
