Trackpad works for a short time then start to move erratically
Hi,
I’ve just done a fresh install to El Capitan with a brand new battery on my MacBook Pro 15” 2009.
The issue i’m having is that the track pad works fine for a while and then after 3-4 minutes it starts to behave erratically making it impossible to select anything.
The only thing that fixes it again for a short time is by hitting it fairly hard, after that it goes back to it weird twitching.
I think i’ve tried pretty much everything….
- Fresh install, happen with both Snow Leopard and El Capitan.
* installed New battery, old one wasn’t bulging
* reset PRAM and SMC (PRAM i got the double chime and SMC the power connector changed colour
* tried with and without the power lead same, same problem
* tried with nothing else is plugged into the computer
* clean it with alcohol and scraped around the edges with a blade
I’m certain it must be a hardware issue as hitting it fixes the problem.
Any ideas welcomed
Thanks
