While all Apple products are designed to work consistently well, things can go awry anytime. This holds true especially for MagSafe charging. Sometimes, it may take longer than usual to charge a device or stop charging it at all. Find what you should do to fix the problem.
Fix MagSafe Charging stops charging the battery unexpectedly
MagSafe charging is based on the same Qi charging technology that other wireless chargers use. When it fails to charge the battery quickly and safely or exhibits other behaviors, check the power port first. Make sure that the power port (where you plug in the MagSafe connector) is clean and free of debris. Why? The port is magnetic and might attract metal objects.
- Disconnect the USB-C (a 24-pin USB connector system) to MagSafe 3 Cable from your Mac and from the power adapter.
- Unplug the USB-C power adapter from the wall outlet.
- Use a clean and dry cloth to wipe the MagSafe 3 port and MagSafe 3 connector.
- Ensure the port and connector are clear of any debris or stains.
- Similarly, make sure the USB-C port on the power adapter and the USB-C connector are clear of any debris.
- Restart your computer.
- Connect the USB-C power adapter to the power outlet.
- connect the USB-C to MagSafe 3 Cable to the power adapter and to your Mac, then try charging again.
You should follow the above steps when you find indicator light on the MagSafe 3 connector flashing amber repeatedly.
Check the AC plug
The Apple power adapter ensure power connectivity. It is shipped with a removable AC plug that has the blades you insert into an electrical outlet. When you find that the Mac notebook isn’t charging when using the AC plug with the power adapter, switch to another Apple AC plug. If the power adapter (fitted with the new AC plug works), the AC plug that came originally with the power adapter will need to be replaced. It should no longer be used, again.
Identify your MagSafe cable or adapter
If your Mac relies on MagSafe to charge the battery, it will use either,
- MagSafe 2 connector
- T style MagSafe connector
- L style MagSafe connector
While the MagSafe 3 connector charges your Mac with a USB-C to MagSafe 3 Cable and a USB-C power adapter, the MagSafe 2 connector uses a MagSafe power adapter connected with the MagSafe to MagSafe 2 converter. Bear in mind, MagSafe 2 and MagSafe power adapters aren't compatible with MagSafe 3.
To identify your cable or adapter, use the list below to find your MagSafe connector.
Check for any software update
Lastly, if the methods above fail to yield the desired results, check if there’s any new software update available. For this,
Click the Apple Menu and choose the System Preferences entry. Then choose Software Update. If there’s a new update available, install it.
Hope it makes sense!
