My MacBook Pro (Retina, 13-inch, Early 2015) is having problems. I have been having this problem since last night and have tried everything to fix it or to simply find whats wrong. The laptop itself immediately turns off when disconnected from the power adapter. The light from the adapter is always Green and never turns Orange, and the laptop itself says that the battery is at 100%. I have tried resetting the SMC and reseting the PRAM 3+ times, which have both done nothing. The battery itself says that it has 0 amperage, and CoconutBattery says that the battery has suffered from failure. Is there anything I can do besides replacing the battery itself? The only abnormal thing that I did was I left the laptop overnight to charge while charging some wireless headphones through the USB port.
Given your systems age your battery is likely past its cycle count Determine battery cycle count for Mac notebooks The charging logic within your system could have also failed. I often see them failing due to using fake chargers! OEM MagSafe Chargers vs Cheap Imposters: Teardown for Truth & Lacking safety features, cheap MacBook chargers create big sparks Do make sure you have a REAL Apple unit, don’t be penny-wise pound-foolish or be taken in by a bad charger which can harm your system as well as be a safety issue in your home/office.
It could be a defective power adapter or a bad cell in the battery itself. Also check the charging port to see if it is loose. The power port may have broken loose from the motherboard.
