My MBP is from late 2011. The battery health is normal, and I had no problems before. One day it randomly decided to not charge. I got a new cord and discovered that wasn't the issue. I did a SMC reset which worked for a few days. It then died while I had it plugged in and wouldn't turn on or charge. I left it plugged in and about 2 1/2 days later it started charging. I've tried everything I could find so far. Just curious if anyone has any other advice to offer before I decide to finally take it to Apple.
