are you suuuuuure you didn’t dent the connector? i know if i had received a battery with a dented connector, i’d immediately contact the seller so you probably dented it yourself and now you’re trying to trick all us but we’re on to you.
You need to remove the fans, logic board etc to remove the touchpad. If you’re just trying to do some deep cleaning, you can remove the battery, loosen the 4 screws holding the touchpad pop it out a little bit BUT you need to be careful to not damage the cable, you’ll need to hold it with one hand while getting all the junk out along the edges. I just did that however next time I will just do a full disassemble as it’s not that difficult, the instructions make it sound more involved than it is.
