MacBook Pro Early 2015 barely charging I got a second-hand MBP about a week ago and today I noticed that when I ran the battery to around 50% it wouldn't charge back. I installed coconutBattery and it shows the charging rate fluctuating at 0-10W.



How do I make my MBP charge properly? Could this be due to faulty charger? I already tried a SMC reset.
Just to clear this up, this was a 13'' MBP. 

I've tested with other chargers and other people's MacBooks and found out my charger was faulty. Got a new one and everything is fine.
