How to Fix a MacBook That Won’t Turn On
If your MacBook is unresponsive, follow these step-by-step solutions to troubleshoot the issue.
1. Check Power Connection 🔌
- Ensure your charger is plugged into a working power outlet.
- Use a different power cable and adapter to rule out a faulty charger.
- If using a USB-C charger, test different ports as some may be damaged.
2. Perform an SMC Reset 🔄
The System Management Controller (SMC) manages power functions. Resetting it can fix power-related issues.
🔹 For MacBooks with T2 Chip (2018 & later):
- Shut down your MacBook.
- Hold
Control + Option (Left) + Shiftfor 7 seconds. - While holding these, press and hold the power button for another 7 seconds.
- Release all keys and wait a few seconds, then turn on your MacBook.
🔹 For Older Intel-Based MacBooks:
- Shut down the MacBook.
- Press and hold
Shift + Control + Option (Left side) + Powerfor 10 seconds. - Release all keys and turn on your MacBook.
3. Boot into Safe Mode 🔧
If your MacBook starts but gets stuck on a black or gray screen, booting into Safe Mode can help resolve software crashes.
- Hold the Shift key immediately after pressing the power button.
- Release it once the Apple logo or login screen appears.
- If Safe Mode works, restart normally and check if the issue is resolved.
4. Check for Screen Issues 🖥️
Sometimes, your MacBook may turn on but the screen remains black.
- Adjust brightness using the keyboard.
- Shine a flashlight at the Apple logo—if you see a faint display, the screen backlight may be faulty.
- Check external display: Connect your MacBook to an external monitor via HDMI or USB-C. If the external monitor works, the issue is likely with your MacBook’s screen.
- Run Apple Diagnostics: Turn off your MacBook, then hold D while turning it on. This will run a diagnostic test and display hardware issues.
If you see the MacBook power light, keyboard backlight, or hear startup chimes but get no display, a screen replacement may be necessary. 🖥️

5. Boot into macOS Recovery Mode 🔄
If your MacBook is unresponsive, macOS Recovery Mode can help reinstall macOS or repair the startup disk.
- Press and hold Command (⌘) + R while turning on your MacBook.
- If the macOS Utilities menu appears, try running Disk Utility > First Aid to fix disk errors.
- If issues persist, reinstall macOS from this menu.
6. Check for Hardware Damage 🛠️
- If liquid damage has occurred, immediately power down your MacBook and do not attempt to restart.
- If there was a recent drop, check for physical damage around the ports, screen, or keyboard.
- Listen for beeping sounds or burning smells – These can indicate logic board or RAM failure.
- Check for overheating – If your MacBook was getting excessively hot before shutting down, it could be a thermal failure.
- Seek professional repair for suspected logic board, RAM, or SSD failure. 🛠️
