Mine did not stop working exactly, but it did start to wobble and miss click a bit. After I did my battery replacement, the touchpad fixed itself. It didn’t wobble anymore and didn’t miss click. I have 2 theories about it:[br]
1. My original battery was swollen, which I never noticed till I replaced it. This could’ve put pressure on the touchpad and messed with it. [br]
2. There was 1 very small component that dropped out of the laptop when I was working on it. No idea what it was, but that might also have messed things up. [br]

Not exactly your issue, but it might help you out.
