Chosen Solution
Recently purchased a new battery replacement from iFixit. I followed the guide to the T when replacing it, however my Mac still won’t turn on. The only thing that’s happen so far is the fan will start running on it’s own, but the Mac itself won’t power up. I’m considering taking to the Apple store to get it checked out, but would like to see if anyone here can answer my question here first. HELP?!
Sorry to say it does sound like you have a deeper issue here. I suspect you have a logic board issue within the charging logic. This can happen when using a fake charger.
