I had a problem with my trackpad not clicking properly as well. Thinking that something had spilled on the trackpad, I removed the battery to check the bottom of the trackpad. With the battery removed, I noticed the trackpad was now clicking properly. It turned out the battery had gone bad and had swelled in the middle of it. This swelling was putting pressure on the bottom of the trackpad and causing it to not click properly. Once the battery was replaced, the trackpad worked just fine.
