Chosen Solution
Hi everyone, I have a second hand MacBook Pro in which the little connector coming from the keyboard is snapped in two. I know that in order to replace a faulty power button, the most straightforward thing to do is replace the entire keyboard, but as everything else about the keyboard is fine, I didn’t want to go and spend 50$ just because of the power button. I figured I should try fixing it myself, but to my disappointment, I couldn’t solder a wire onto the paper membrane, it just melted through, It seems like the connection paths are made of some powder drawn on. What i want is to route the power switch back to the logic board power on contacts, I have a few ideas, either A, find some sort of switch (maybe from a phone) that has copper paths can fit in there and route the wiresB, use conductive glue to extend thin wires on whats left of the power button connector. Does anyone know how well conductive glue holds up, as i have never used it, or does anyone have a better solution, (can other power switches fit in there?)
I think you’ll end up making more of a mess here with either of your two plans. Conductive glue only works as a small drop bonding two things together electrically, not to create wire paths. Finding a switch that meets the space limitations will be tricky and you would still need a means to hold the switch. Basically, I think your best option here is to replace the full upper case and not try to re-invent things.
