Fixing a MacBook Air That Won’t Turn On
## Direct Answer
If your MacBook Air won’t turn on, try pressing the power button for 10 seconds to discharge any residual power, then plug in the charger and press the power button again. If this doesn’t work, reset the System Management Controller (SMC) by pressing the power button, the Command (⌘) + Option (⌥) + Shift (⇧) + Power buttons at the same time, and hold them for 10 seconds.
## Step-by-Step Guide
To troubleshoot your MacBook Air, follow these steps:
1. **Check the Power Cord and Charger**: Ensure the power cord and charger are properly connected to both the MacBook Air and the power outlet.
2. **Check the Battery**: If your MacBook Air has a removable battery, take it out and press the power button for 5 seconds to discharge any residual power. Then, put the battery back in and try turning it on.
3. **Reset the SMC**: Press the power button, the Command (⌘) + Option (⌥) + Shift (⇧) + Power buttons at the same time, and hold them for 10 seconds.
4. **Reset the Power Management Unit (PMU)**: Press the power button, the Command (⌘) + Option (⌥) + P + R buttons at the same time, and hold them for 10 seconds.
5. **Try a Different Power Outlet**: Plug your MacBook Air into a different power outlet to rule out any issues with the electrical supply.
