Hi guys, does anyone here know about electrically conductive glue or adhesives?

I was trying to repair a laptop today and pulled a thin wire from the power button. The machine still switches on if I hold the wire to the terminal, so I know the computer still works.

However, I don't have a soldering iron with a fine enough tip to resolder it on. I was thinking of glueing it on but I don't know anything about electrically conductive adhesives, could anyone here point me in the direction of some good info?

I have not used the products below but have used something like them in the dim, dark past. Maybe this will give you some ideas?

Try this one...

Check with a local ham/amateur radio type and they may also be able to help with ideas and/or another way to help.

I've used a conductive wire glue for some projects that might work if you apply it with a toothpick or something fine like that, https://smile.amazon.com/Sciplus-Electrically-Conductive-Soldering-Wire/dp/B000Z9H7ZW/. Be cautious!

Thanks guys, at those prices I think I'll try both.

The power button is on a small separate circuit board and I managed to find a replacement (it's an older laptop and I wasn't sure if I could find one) so no big loss if I screw it up.

I don't have a lot of practice with soldering, especially very fine work so these could be a very useful tool.

you can make a smaller tip by wrapping a length of copper wire around your soldering iron top with one end sticking out as a smaller tip.

Here we go, found a image http://electriciantraining.tpub.com/14176/css/Solder-73.htm

Wow, Eugene! I think Iím going to say something to my uncle for not teaching me that when I was small (and could see tiny things without a magnifier)!
