If your MacBook Air battery is not charging after a restart, try resetting the System Management Controller (SMC) by pressing the power button, the Command + Option + Shift + Power buttons, or the Power button and the Volume Down button, depending on your MacBook model.
## Step-by-Step Guide
1. **Identify Your MacBook Model**: Check the bottom of your laptop for the model number to determine the correct SMC reset method.
2. **Reset the SMC**:
– For MacBook Air models from 2018 and later: Press and hold the Power button and the Volume Down button for 10 seconds.
– For MacBook Air models from 2015-2017: Press the Power button, Command + Option + Shift + Power buttons for 10 seconds.
– For MacBook Air models from before 2015: Unplug the power cord, remove the battery (if possible), press the Power button for 5 seconds, and then replace the battery and plug in the power cord.
3. **Reset the Power Management Unit (PMU)**: If resetting the SMC doesn’t work, try resetting the PMU. The process is the same as resetting the SMC on older models.
4. **Update Your MacBook**: Ensure your MacBook is running the latest software. Go to System Preferences > Software Update to check for any available updates.
5. **Check for Physical Damage**: Inspect the charging cable and port for any signs of physical damage. Clean out any debris that might be blocking the charging port.
6. **Contact Apple Support**: If none of the above steps work, it may be a hardware issue, and you should contact Apple Support for further assistance.
