Solved Replaced The Battery With Ifixit Battery Now Trackpad Not Working Macbook Air 13 Mid 2012

Chosen Solution

After battery replacement with iFixit 2012 MacBook Air battery, trackpad is not working now.

Hi guys, just to close this out. When I replaced the battery, I mistakenly removed the trackpad setting screw. (in the front middle) when I realized my mistake, then I didn’t know how to reset it. By trial and error, I reset it so that the head was exactly flush with the surface. Do Not tighten this screw, it is a setting screw. Flush with surface got the trackpad working perfectly. Thanks to you all for your support.
