Chosen Solution

I have attempted to resolder the battery connector on, and out of the 4 gold tabs on the back, ive managed to knock one off and loose it… Does this mean the logic board is completely f’d now or can I just tack it to where the gold thing use to be ? The only other problem I had is the solder was not staying melted with a soldering iron. Maybe a hot air gun would be better, or low melt alloy…

@zaceustace your description is a bit vague. Take some pictures of what you got there and post those with your question. Use this guide for that so that we can see what you see. It does sound like you have issues with one of the solder pads. you may have to consider rerouting those contacts or try to rebuild the solder pad.

You need to have the right heat as well as plenty of flux and good solder to make the connection. Only practice will make perfect.
