Fixing a MacBook Air Battery That Won’t Charge After a Drop
## Direct Answer
If your MacBook Air’s battery won’t charge after a drop, try resetting the System Management Controller (SMC) and the Power Management Unit (PMU). If that doesn’t work, inspect the charging port and cable for damage, and check for loose connections. If the issue persists, it may be a hardware problem that requires professional repair.
## Step-by-Step Guide
To fix the issue, follow these steps:
1. **Reset the SMC**: Shut down your MacBook Air, locate the following keys: Power button, Command (⌘) + Option (⌥) + Shift (⇧) + Power. Press and hold these keys while powering on your MacBook Air. Hold them for 10 seconds, then release. This resets the SMC.
2. **Reset the PMU**: On older MacBook Air models, you can reset the PMU by pressing the Power button, Command (⌘) + Option (⌥) + P + R. Hold these keys for 10 seconds, then release.
3. **Inspect the Charging Port and Cable**: Check the charging port for any signs of physical damage, such as bent or broken pins. Also, inspect the charging cable for any signs of wear or damage. Try using a different charging cable to rule out any issues with the current one.
4. **Check for Loose Connections**: Ensure that the charging cable is properly connected to both the MacBook Air and the power source.
