A Mac computer not turning on can be a frustrating experience for any user. There are a variety of reasons why your Mac may not be turning on, ranging from a dead battery to a hardware failure. In this article, we’ll go through some troubleshooting steps to help you diagnose and fix the issue.

Check the Power Connection

The first thing to check when your Mac won’t turn on is the power connection. Make sure the power cord is securely connected to the Mac and the power outlet. If you’re using a MacBook, make sure it’s charged or connected to a power source. If the power connection is loose or not connected, your Mac won’t turn on.

Reset the SMC

The System Management Controller (SMC) is responsible for managing various hardware functions on your Mac, including power management. A reset of the SMC can often help resolve issues with your Mac not turning on. To reset the SMC on a MacBook, follow these steps:

1. 1. Shut down your MacBook.
2. 2. Press and hold the Shift + Control + Option keys on the left side of the keyboard and the power button at the same time.
3. 3. Release all the keys and the power button at the same time.
4. 4. Press the power button to turn on your MacBook.

Check the Display

If your Mac is turning on, but the display is not turning on or remains blank, there may be an issue with the display. Try connecting your Mac to an external display to see if the issue is with the display or a more serious hardware problem.

Boot in Safe Mode

Booting your Mac in Safe Mode can help diagnose and fix issues with your Mac. To boot your Mac in Safe Mode, follow these steps:

1. 1. Shut down your Mac.
2. 2. Press the power button to turn on your Mac.
3. 3. Immediately press and hold the Shift key.
4. 4. Release the Shift key when you see the login screen.

Conclusion

When your Mac won’t turn on, there are a variety of reasons why it may be happening. By following the troubleshooting steps outlined in this article, you can diagnose and fix the issue. Remember to always check the power connection first, reset the SMC, check the display, and try booting in Safe Mode. If none of these steps work, it may be time to take your Mac to a professional for further diagnosis and repair.
