Title:

Intermittent trackpad responsiveness after replacing cable

Text:

Hey all. Have a weird issue ongoing with my trackpad intermittently becoming laggy and semi-responsive.
Initially, the trackpad on my Macbook stopped working. Upon inspection, a piece of sand had gotten in and stuck between the casing and battery/trackpad cable. Somehow the heat generated caused the piece of sand to get hot enough to burn a miniature hole through the trackpad cable. Crazy. Thankfully, it didn’t go thru fully and do damage to the battery.
Anyway, I’ve replaced the trackpad flex cable since and the trackpad is working again, but with intermittent issues. When the laptop is turned on, the trackpad often works perfectly. Then, during usage it starts to become semi-unresponsive. The pointer doesn’t fully track my finger movements and the haptic feedback becomes intermittent.
Sometimes, this doesn’t happen at all. And sometimes it’s happening from the moment I turn it on.
When this happens, it never seems to go back to full working order. A restart doesn’t fix the issue. But shutting down and resetting the NVRAM often '''does''' work, until it occurs again.
I thought the trackpad cable I’d received was faulty, so I bought another one and replaced the original replacement. Same issue. So the trackpad cable is not at fault.
Next step for me is to replace the trackpad itself, thinking maybe it has become defective. But thought I’d ask here incase anyone has any software related suggestions. The NVRAM reset temporary fix has thrown me off a bit.
Thanks in advance to anyone who can help!
