So, a few days ago, I plugged my iPod in to sync. Worked fine. Now today, I plugged it in and it said "too much power blah blah blah" okay, switched the cord, same thing. Plug in my mouse... nothing. Reset pram, and smc(u believe is the term) tried safe mode, didn't know what to do , rebooted. I dunno what else to try, if anything. When I got the laptop and updated to mavericks, one of the ports died. And now the other one is doing this randomly. One thing that may have caused it was it does over night and I turned it back on at 8 pm, and the whole thing rebooted, not restoring from a previous state like normal. And I don't want to hear that I need a logic board as everything is fine and it was fine until today.
