A MacBook that refuses to turn on, even when using a new charger, can be frustrating. The issue may stem from hardware problems, software glitches, or even external power source issues. Below, we’ll explore the possible causes and solutions to help revive your MacBook.
1. Check the Basics
Before delving into technical troubleshooting, start with the basics:
-
Verify the power outlet: Try plugging the charger into a different power outlet to rule out electrical issues.
-
Inspect the charger and cable: Even if it’s new, the charger or cable might be defective. Test with another compatible charger if available.
-
Check for physical damage: Look for signs of wear, liquid damage, or cracks on your MacBook that may indicate internal hardware issues.
2. Perform a Power Cycle
A power cycle helps clear minor software glitches that may prevent the MacBook from booting:
-
Disconnect the charger and any connected accessories.
-
Press and hold the power button for at least 10 seconds.
-
Release the power button and wait a few moments before trying to turn it on again.
3. Reset the System Management Controller (SMC)
If the MacBook still does not turn on, resetting the SMC may help as it controls power functions.
- For Intel-based MacBooks:
-
Connect the charger.
-
Press and hold Shift + Control + Option (on the left side of the keyboard) and the power button for 10 seconds.
-
Release all keys and then press the power button again to turn it on.
-
- For Apple Silicon MacBooks:
-
Shut down the Mac (if it’s unresponsive, force shut down by holding the power button).
-
Wait for 30 seconds and turn it back on. There is no separate SMC reset for Apple Silicon models.
-
4. Check the Display
If the MacBook appears to be powered on but there’s no display:
-
Adjust the brightness using the keyboard.
-
Connect an external monitor to see if the issue is with the built-in display.
-
Shine a flashlight on the screen; if a faint image appears, the backlight or display may be faulty.
5. Boot into Safe Mode
If your MacBook powers on but doesn’t boot correctly, try Safe Mode:
-
For Intel-based MacBooks: Hold Shift immediately after pressing the power button until the login screen appears.
-
For Apple Silicon Macs: Press and hold the Power button until startup options appear, then select your disk and hold Shift while clicking “Continue in Safe Mode.”
6. Try Internet Recovery Mode
If macOS is corrupted, you can reinstall it via Internet Recovery:
-
Turn off the MacBook.
-
Hold Command + Option + R and press the power button.
-
Release the keys when the spinning globe appears.
-
Follow the on-screen instructions to reinstall macOS.
7. Check for Battery Issues
A faulty battery can prevent a MacBook from turning on:
-
If the battery is completely drained, let the charger stay connected for at least 30 minutes before attempting to power it on.
-
If your MacBook has a removable battery, try reseating or replacing it.
8. Seek Professional Help
If none of the above solutions work, professional repair may be necessary. Visit an Apple Authorized Service Provider or an Apple Store in Auckland for diagnosis and repair.
Final Thoughts
A MacBook not turning on can have various causes, but troubleshooting step-by-step can help identify the issue. If your Mac still doesn’t respond after these steps, professional intervention is the best course of action to avoid further damage.
