Fixing MacBook Pro Battery Not Charging After Restart
## Direct Answer
To fix a MacBook Pro battery not charging after restart, try resetting the System Management Controller (SMC) and the Power Management Unit (PMU). If that doesn’t work, check your power adapter, MagSafe port, and battery health. In some cases, you may need to update your MacBook Pro’s operating system or visit an Apple Store for further assistance.
## Step-by-Step Guide
To troubleshoot and potentially fix the issue, follow these steps:
1. **Reset the SMC**: Shut down your MacBook Pro, locate the following keys: Power button, Command (⌘) + Option (⌥) + Shift (⇧) + Power button. Press and hold these keys while powering on your MacBook Pro. Hold them for 10 seconds, then release. This will reset the SMC.
2. **Reset the PMU**: For older MacBook Pro models, shut down your laptop, locate the following keys: Power button, Command (⌘) + Option (⌥) + P + R. Press and hold these keys while powering on your MacBook Pro. Hold them for 10 seconds, then release. This will reset the PMU.
3. **Check the Power Adapter and MagSafe Port**: Ensure your power adapter is functioning properly and that the MagSafe port is clean and free of debris.
4. **Check Battery Health**: Click the Apple logo in the top left corner, select “About This Mac,” then click “System Report.” Under “Hardware,” select “Power” and look for “Cycle Count” and “Condition.” If your battery health is poor, it may be a sign that your battery needs to be replaced.
5. **Update Your Operating System**: Ensure your MacBook Pro is running the latest version of macOS. To check for updates, click the Apple logo, select “System Preferences,” then click “Software Update.”
