Please refer to Apple’s website to find out the original stock adaptor for your MacBook. If you turn off the Mac or put it to sleep, the power adapter will start charging the Mac. You may still use your MacBook without draining its battery, but the battery won’t charge. If you use a low-wattage adapter in a high-power consumption MacBook, the power adapter barely provides enough power to run your MacBook but not enough power to charge the battery.įor example, if you connect a Macbook Air charger (30W) to a 15" MacBook Pro (87W), you could get a battery not charging notification, and the charger will get hot very soon. The low-wattage adapters are used in low-power consumption MacBooks like MacBook Airs and 12" MacBooks, while the high-wattage adapters are used in 15" and 16" MacBook Pros. You may quickly get confused with the chargers if you have a few MacBook Airs, MacBook Pros, iPads and iPhones in your household. The new MagSafe 3 chargers come in 67W, 96W and 140W. The MagSafe 1 and 2 chargers come in 45W, 60W and 85W. You need a new charger.Īpple uses a few types of chargers for different MacBook models.
If your charger keeps turning off, you most likely have a faulty charger. Other solutions include using an uninterruptible power supply (UPS) to filter out the line noise or plugging the charger into a different circuit, eg., the other side of a house or office, upstairs or downstairs.
Unplug the charger, wait for 1 or 2 minutes and plug the charger back in to see whether the charger works or not. The charger will shut down when it senses too much line noise from a socket. The AC line noise from power tools, fluorescent lights, refrigerators, and other sources may interfere with the MacBook charger. Unplug the charger immediately and let it cool down before using it again. If you place the charger in a poorly ventilated area, such as on a sofa, bedding or a pillow, the charger may turn itself off if it gets too warm. The MacBook charger can become warm during normal use. Stop using the cable immediately and get a new replacement cable. The removable USB-C cable is prone to get damage by bending the plugs at the two ends. If your MacBook starts charging when you wiggle the USB-C cable, the cable is not connected properly. Believe it or not, these simple checks often fix the MacBook battery not charging issue. Make sure the USB-C cable is fully inserted into the charger. In addition, the USB-C charger uses a removable USB-C charging cable.
