This method can sometimes clear stuck power states that prevent startup.
Check for External Hardware Issues
External devices can interfere with startup processes. Disconnect all peripherals such as printers, external drives, or USB devices. Then, try turning on your MacBook. If it powers on, one of the peripherals might be causing the problem.
Inspect the Battery Status
A drained or faulty battery can prevent your MacBook from powering on. Connect your MacBook to power and check if the charging indicator shows activity. If not, consider replacing the battery or seeking professional assistance.
Handling MacBook with Non-Responsive Screen
Sometimes, your MacBook might turn on, but the screen remains black. Here’s what to try:
- Adjust the brightness keys to see if the screen lights up.
- Press the Caps Lock key; if the LED indicator toggles, the system is responsive.
- Force a restart by pressing and holding the power button for 10 seconds.
If the device turns on but the display remains black, the issue might be with the display hardware itself.
Reset the System Management Controller (SMC)
The SMC controls hardware functions like power management and battery charging. Resetting it can fix power-related issues:
- Shut down your MacBook.
- Connect your MagSafe or USB-C power adapter.
- Press and hold the Shift, Control, Option keys, and the power button simultaneously for 10 seconds.
- Release all keys and turn on your MacBook.
This reset often resolves issues related to power, battery, and thermal management.
Reset the NVRAM or PRAM
NVRAM/PRAM stores certain settings that might prevent startup if corrupted. To reset:
- Shut down your MacBook.
- Turn it on and immediately press and hold the Option, Command, P, and R keys.
- Hold these keys for about 20 seconds, during which your Mac may restart.
- Release the keys and see if the MacBook turns on normally.
This can fix display resolution, startup disk, and other hardware-related issues.
Boot into Safe Mode
Safe Mode disables unnecessary software and performs a startup check. To enter Safe Mode:
- Turn on your Mac and immediately press and hold the Shift key.
- Release the Shift key once the login window appears.
If your Mac boots in Safe Mode, the problem might be related to software conflicts. Try updating or removing recent software changes.
Use macOS Recovery Mode
Recovery mode allows you to repair disks or reinstall macOS:
- Turn on your Mac and immediately press and hold Command and R keys.
- Keep holding until the Apple logo or spinning globe appears.
- Here, you can run Disk Utility to check disk health or reinstall macOS if necessary.
This step is essential if your startup disk shows errors or has been corrupted.
Run Disk Utility to Check Disk Health
A failing or corrupted disk can prevent startup:
- Access macOS Recovery Mode as described above.
- Select Disk Utility from the menu.
- Choose your startup disk and click First Aid to scan and repair errors.
If repairs are unsuccessful, you might need to erase and reinstall macOS, but back up data first if possible.
