How to solve trackpad problem on Macbook pro?

Question

macbook

Hello! There is an old MacBook Pro A1728 mid-2012. Works like a clock. Everything is completely satisfied. Changed the battery several times.

But just a few months this thing happened: the trackpad began to behave very strangely. No moisture ingress, cleaned everything several times. Even if the laptop is just standing there, it can suddenly start doing something with this trackpad.

The problem was not solved by replacing the trackpad. The first 6 days worked norms, then a similar thing began. I don't think there are any software bugs. Booted in safe mode.

What are the options to solve all this?

Answer 1

Wear and tear most likely. For so many years of work. You have to understand that there are very subtle mechanics in fact, if I can put it that way at all, and I'm not even sure that it is included in such a run. I myself used a similar device until the end of 2018 until I wanted a faster machine)
Most likely, you can replace the trackpad (but I'm not sure that myself) and everything will return to normal, but these are just my guesses

Answer 2

Has the line changed or not? Vdrkg during installation was moved and temporarily earned
+ the same about the cable connector on the board - maybe clean it, all of a sudden
