I was constantly getting a notification that USB ports had been disabled due to an accessory using too much power. Most of the time there was nothing plugged in when I received the notification. So, in an attempt to fix this problem I reset the SCM(option-command-power while off), but that really screwed everything up. I was never able to boot up fully again. It would ask for password, but never get passed that. Once I was able to successfully boot in safe mode. The biggest problem is that after resetting the SCM it never again accepted a charge. I’m thinking that the USB ports stayed disabled. Now, my battery is dead and I can’t charge it to even try fixing it. Any ideas? I’m at a loss. Thanks

Edit: Assuming it is not a hardware problem (which it seems like it is), are there any ideas on how to get the battery charged to at least attempt to work on it?

    Sounds like hardware error. I would take it in for repairs. – jksoegaard Feb 19 at 22:49

    Try resetting the SMC again, but if things get worse after an SMC reset, it's most likely the logic board. – Allan Feb 19 at 23:06
  • I did do a hardware test(holding D down on boot up) before resetting SCM to see if it would say anything about USB issues. Everything checked out ok in that test. – Joshua Goossen Feb 19 at 23:30
  • Not being able to charge is a hardware issue. It must go in for service as there is nothing you can do to overcome this. – Allan Feb 20 at 13:29
  • Try resetting the PRAM. It's worth a shot too. support.apple.com/en-us/HT204063 – technogeek1995 Feb 20 at 15:44
