My Battery Doesn’t Need Replacing, Now What?
If you have checked your battery’s condition and health, and everything looks good, there are a few other Macbook battery charger problems you can look for before taking your notebook to be repaired, or purchasing a new battery.
Make sure that the outlet you are using is working correctly. To do this simply plug in another appliance that you know works, such as a lamp. If the appliance works, then move onto the next step.
Make sure that you are using the correct power adapter for your MacBook, while you can use a higher wattage power adapter, using one with a lower wattage will cause Macbook battery charger problems.
Check for ‘line noise’. To do this unplug the power adapter from the outlet and let it sit for a minute, then plug it back in.
- If the charger now works, then it is likely that ‘line noise’ was the cause of the battery issue, and your adapter’s over voltage protection feature turned it off.
- Line noise can be caused by lights with ballasts, and larger appliances such as refrigerators on the same electrical circuit as your notebook. Plugging your MacBook into a different circuit, or a UPS device should help alleviate this problem.
- Make sure that your MacBook’s power adapter has plenty of ventilation and isn’t overheating. If it becomes too hot, it will shut itself off to prevent damage, which causes the Macbook battery to stop charging.
- Check the plugins on both the power outlet end, and the notebook end for damage and debris, and also check the entire power cord for cracks and fraying. Broken and damaged cords are common causes of Macbook battery charger problems, so you should always check to make sure you don’t have to replace the cable.
- Check for dirty connectors or stuck pins. If you notice that a pin is stuck down, unplug and replug it in the MagSafe adapter, this should make the pins move and reset themselves. If a stuck pin doesn’t reset itself, gently press the pin to the side using your fingertip. If the connectors are dirty, you can gently clean them using a cotton swab or soft toothbrush. Just make sure that the cord is unplugged from both the outlet and the notebook, and ensure that you don’t get any cotton fibers stuck in the pins.
- Check for software updates. Occasionally, there will be a software update available that will improve communications between your notebook and the power adapter. To check for updates go to the Apple menu, and then choose Software Update.
- Once you have completed all the steps, check and see if the battery is now charging and if the LED is lit. If it is, then your Macbook battery charger problems have been solved. If it isn’t, then you will need to take your computer to an Apple service provider or dealer and have them check the power adapter and the battery.
Hopefully, one of the above steps will work for you, and your battery will now be charging, but if not, even if your notebook is out of warranty, you still may be eligible for a replacement adapter or battery free of charge. Make sure you have it looked at before purchasing a new battery.
