How to Fix a MagSafe Power Adapter

Make sure the power outlet that you plug your adapter into works.

The MagSafe Power Adapter is a power cord manufactured by Apple that is used to power Apple devices. Your MagSafe Power Adapter may not function properly because your power outlet does not work, the power adapter overheats, the pins are bent or the adapter is dirty. Fix your power adapter by ensuring the power outlet to which it is connected is working properly, keeping your adapter cool, straightening the pins, cleaning the adapter connector and cleaning the connector on your computer.

Things You'll Need

• Toothbrush
• Cotton swab
• Rubbing alcohol

Instructions

1. Make sure the power outlet you plug your power adaptor into is working properly. Test the power outlet by plugging an appliance that you know works, such as a lamp or a television, into it.

2. It is normal for the power adapter to heat up a little during use. Disconnect your adapter and let it cool off if it overheats. The adapter should function correctly after it has cooled.

3. Your MagSafe adapter may malfunction due to the pins located in the connector getting stuck. For example, all of the pins may get stuck in a downward position. When a pin gets stuck, unplug the power adapter from the power port and plug it back in. This makes the pins shift and set themselves again into a neutral position. If you are having trouble getting the pins to reset themselves, press them gently sideways with a non-abrasive object such as your finger.

4. Check the power port on your Apple computer and the adapter connector on your MagSafe for any damage, and clean them both. Clean the computer port or the power adapter plug by taking the adapter out of the outlet or by taking the battery out of the computer. Clean the connectors carefully using small, precise tools, such as a cotton swab or a toothbrush with soft bristles. Ensure no cotton fibers stick to the pins. Use rubbing alcohol if you want to clean the connectors thoroughly. Ensure that all connectors are completely dry before using your adapter or computer.
