Logic board reset may repair non-functional FireWire
Resetting the PMU is a standard troubleshooting step when dealing with all hardware issues. The PMU (Power Manger Unit) is basically a computer inside the computer that handles the power flow throughout the system. There is no risk in resetting the PMU. Just don't press it more than once between restarts. Also, You do NOT need to hold it down for 60 secs. because this can also cause problems. Sometimes it needs to be reset more than once (reset PMU, restart, reset PMU again, restart...) to resolve the issue.
