Fixing MacBook Air Battery Not Charging Randomly
Direct Answer
To fix a MacBook Air battery that’s not charging randomly, try resetting the System Management Controller (SMC) and the Power Management Unit (PMU), then calibrate the battery. If the issue persists, check for loose connections, update your operating system, and consider visiting an Apple Store or authorized service provider.
Step-by-Step Guide
1. **Reset the SMC**: Shut down your MacBook Air, locate the following keys: Power button, Command (⌘) + Option (⌥) + Shift (⇧) + Power button. Press and hold them for 10 seconds, then release. This will reset the SMC.
2. **Reset the PMU**: Disconnect the power cord, remove any other cables, and press the Power button for 5 seconds. Release the Power button, then reconnect the power cord and turn on your MacBook Air.
3. **Calibrate the battery**: Charge your MacBook Air to 100%, then unplug the power cord and let it discharge to 0%. Repeat this process several times to calibrate the battery.
4. **Check for loose connections**: Ensure the power cord is securely connected to both the MacBook Air and the power outlet.
5. **Update your operating system**: Go to System Preferences > Software Update to ensure you’re running the latest version of macOS.
