Replaced trackpad only works when touching laptop body?!?
I recently replaced the trackpad (and mounting brackets) on my MBP, as it had been damaged by a swollen battery.
I thought the new trackpad was faulty, but it turns out that it works fine, as long as I am touching the laptop body! I assume this is an issue with electrostatic charge or similar, so that by touching the rest of the laptop I am somehow completing a circuit?
When I'm not touching the laptop (so that the only contact is with the trackpad) the cursor behaves erratically, but as soon as I touch the aluminium body it works perfectly. Do I need to somehow ground or earth the component?
Any advice greatly appreciated, please!!
