Otherwise it doesn’t work. My phone shows it’s connected but no sound comes out. When off the charging cord it won’t turn on.

Is there any kind of a blink code with the JBL Flip 3? I get 10 white charging light blinks and then it does a quick reset and blinks 10 more times.

I found out the battery tab screw holes are slightly misaligned by about 1/2 mm. This causes the battery to wedge in too tightly to the track pad which is directly above. Using a small drill bit I moved the holes slightly allowing the battery to move slightly toward the center of the laptop. This took the pressure off the track pad. Also I took the clear plastic covering off as well. It works great now.

I followed the instruction carefully and the battery works great. However, now my trackpad won't depress in all but the lower right corner. Anyone know how to fix this?
