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?
