How to Fix Your MacBook Pro Charging Issue When Turned Off

Understanding the Issue

Have you ever encountered the frustrating situation where your MacBook Pro only charges when turned off, but not when it's on or half-charged if it's in use? This problem can be quite annoying, especially when you need to extend your battery life during a meeting or while working outside. There are several possible reasons for this issue, and in this guide, we will explore the most common causes and effective solutions.

The Potential Causes

1. Inadequate Power Adapter: The power adapter may not be delivering enough power to both run the MacBook Pro and charge the battery simultaneously. Ensure that your power adapter is compatible with your MacBook Pro by checking its wattage. If you're using a third-party adapter that's below the recommended wattage, it might not provide sufficient power.

2. System Management Controller (SMC) Reset: The SMC is responsible for managing various power-related tasks on your Mac. Sometimes, the SMC can become corrupt or misconfigured, leading to charging issues. Resetting the SMC is a common troubleshooting step that can often resolve these problems. Here's how to reset the SMC on your MacBook Pro:

For MagSafe adapters:

Shut down the Macbook Pro. Unplug the MagSafe adapter from the battery. Press and hold both the Shift Control Option keys along with the power button for 10 seconds. Release the keys and plug in the adapter. Turn the MacBook Pro on.

For non-MagSafe adapters (2011 models and later):

Shut down the Macbook Pro. Unplug the power adapter from the computer. Press the power button until you see the startup manager screen or the Apple logo appears. Hold the Shift Control Option keys and the power button for 10 seconds. Release the keys and plug in the power adapter. Turn the MacBook Pro on.

3. Software Problems: Sometimes, software issues can interfere with the charging process. Check for and install any available software updates, including macOS updates, which can often resolve such issues.

Additional Tips

Here are some additional steps you can take to resolve the charging issue:

Check for physical damage or wear on the power adapter and the charging port on your MacBook Pro. Ensure that the cables are properly seated and not damaged. Try using a different power outlet or an Apple certified power adapter. Watch the battery health of your MacBook Pro as it ages, as older batteries may not charge properly even with a suitable power adapter.

When to Seek Professional Help

If the above solutions do not work, there might be a more serious issue with your MacBook Pro, such as a faulty SMC or a damaged battery. In such cases, it's best to take your MacBook Pro to an Apple authorized service provider or an Apple Store. They can conduct a thorough diagnostic test and provide the appropriate repair or replacement services, ensuring your device returns to working order.

Conclusion

Your MacBook Pro's charging issues when turned off can be complex, but with the right troubleshooting steps and the necessary tools, you can often resolve the problem yourself. Remember, always use an appropriately wattage power adapter, properly reset the SMC when necessary, and keep an eye on the battery health of your MacBook Pro. If in doubt, seek professional help to avoid further damage to your device.
