Fixing a Black Screen on MacBook Air After Restart
## Direct Answer
To fix a black screen on your MacBook Air after a restart, try resetting the System Management Controller (SMC) and the Power Management Unit (PMU) by pressing the power button, the command+option+shift+power buttons, or the power button and the command+option+P+R keys, depending on your MacBook Air model.
## Step-by-Step Guide
1. **Identify your MacBook Air model**: Check the bottom of your MacBook Air for the model number to determine the correct keys to use.
2. **Reset the SMC**:
* For MacBook Air models from 2018 and later: Press the power button, then immediately press and hold the command+option+shift+power buttons.
* For MacBook Air models from 2015-2017: Press the power button, the command+option+shift+power buttons, and the power button at the same time.
* For MacBook Air models from 2010-2014: Unplug the power cord, press and hold the power button for 5 seconds, then release the power button and plug in the power cord.
3. **Reset the PMU (for older models)**: Press the power button and the command+option+P+R keys at the same time.
4. **Wait for the MacBook Air to boot up**: If the MacBook Air boots up normally, the issue may be resolved.
