## Fixing Battery Not Charging on MacBook Air After Sleep Mode
If your MacBook Air’s battery isn’t charging after sleep mode, try resetting the System Management Controller (SMC) and the Power Management Unit (PMU): shut down your MacBook, locate the following keys, and press them simultaneously – the power button, the Command (⌘) key, the Option (⌥) key, and the Shift (⇧) key. Hold them for 10 seconds, then release and turn on your MacBook.
## Step-by-Step Guide
1. **Reset the SMC**: Shut down your MacBook, locate the following keys, and press them simultaneously – the power button, the Command (⌘) key, the Option (⌥) key, and the Shift (⇧) key. Hold them for 10 seconds, then release.
2. **Reset the PMU**: Unplug the power cord, press the power button for 5 seconds to discharge any residual power, then plug the power cord back in and turn on your MacBook.
3. **Update Your MacBook**: Ensure your MacBook is running the latest version of macOS, as updates often include bug fixes and improvements for battery charging.
