How do I troubleshoot my Macbook that won't turn on?
assistant
To troubleshoot your Macbook that won't turn on, first try pressing and holding the power button for at least 10 seconds. If the Macbook still does not turn on, then check to see if the power indicator light is on. If the light is on, it could be that the Macbook's operating system is not starting up properly and you may need to boot into safe mode. Finally, if the Macbook still won't turn on, then you may need to take it in to a professional for further troubleshooting.
