my MacBook Pro 2016 13inch no touchbar just randomly stopped charging. I hear the charging chime whenever I plug the charger in but it says battery is not charging, and using the power as source. Yesterday it randomly restarted 3 times. I've reset the SMC, but it didn't work. I'm planning on bringing it to Apple Store, what would they most likely do for a MacBook Pro that still has 5 months left from the limited warranty? Do they usually fix it in this time or replace it? Has anyone experienced this? Also, how do I back up all my stuff from my MacBook?
