Unplug USB-C power adapter
Check the power outlet
If your USB-C power adapter isn't charging your MacBook, MacBook Air, or MacBook Pro, first unplug the power adapter from the power outlet, wait a few seconds, and plugin it back in. If that doesn't help, try the following:
Make sure that you're connecting your USB-C power adapter to a working power outlet. Unplug your USB-C power adapter from the power outlet, then plug in a known working device, such as a lamp or clock to confirm that it will power on. If the power outlet works, connect your USB-C power adapter again and try to charge your Mac. If your Mac still won't charge, shut down your Mac and close the display for 30 seconds, then open the display and try to charge your Mac again. If you're not using a Mac with Apple silicon, reset the SMC.
Check for line noise issues
If your MacBook starts charging after you plug the power adapter back in, this might indicate an issue with line noise (disruption caused by stray electromagnetic signals) from your power outlet. The power adapter automatically shuts off when its built-in voltage protection feature senses line noise from an outlet.
Some possible sources of line noise include lights with ballasts, refrigerators, or mini-refrigerators that are on the same electrical circuit as the outlet you're using. Plugging the power adapter into an uninterruptible power supply (UPS) or an outlet that's on a different circuit can help.
If your power adapter continues to not work when connected to a functioning outlet, take your adapter to our MacBook repair shop for a diagnosis.
Check the MacBook AC plug or cable
Your power adapter comes with a removable AC plug. If your MacBook doesn't charge, try charging with another Apple AC plug.
Your MacBook comes with a USB-C cable that charges the computer. You can find out if this cable is causing your charging issue by trying another USB-C cable. It’s important to note that not all USB-C cables can charge your MacBook, MacBook Air, or MacBook Pro, so make sure the cable you try is designed to be compatible with your device.
If your MacBook charges with one USB-C cable but not another, immediately stop using the cable that doesn't work and get your cable and power supply checked.
If your MacBook begins charging only when you wiggle or move the USB-C cable or Apple Power Adapter Extension Cable, immediately stop using the cable and get your cable and power supply assessed.
Check for updates
In some incidents, software or firmware updates might be available for your computer that improve communication with your power adapter. If your MacBook, MacBook Air, or MacBook Pro isn't charging as expected, check for software updates on your Mac. If updates are available, update your MacBook and try charging your MacBook again.
Check for ventilation around the area
The USB-C power adapter can overheat during normal use, so be sure to use it in a well ventilated area. Always plug the power adapter directly into a power outlet using the AC plug, or place it on a table or other well ventilated area when using the Power Adapter Extension Cable (sold separately).
Avoid placing your adapter in a poorly ventilated area, like on a couch, thick carpeting, bedding, or a pillow. Avoid covering the adapter with a blanket or other insulation.
The power adapter might turn itself off if it gets too warm. If this happens, disconnect the USB-C cable from your Mac notebook, then let the power adapter cool down before handling it.
When you plug in the USB-C power adapter, it might spark where the blades of the plug enter the outlet. This is generally normal and can happen when you plug any electrical appliance into a power outlet.
