MacBook Won’t Turn On: Troubleshooting and Repair Guide

There’s nothing more frustrating than a MacBook that refuses to turn on. Unlike other issues, a dead MacBook can’t be circumvented, leaving you feeling helpless. However, with the right approach, you can diagnose and potentially fix the problem. In this guide, we’ll walk you through the common causes of a MacBook that won’t turn on and provide step-by-step instructions to troubleshoot and repair your device.

Before we dive into the troubleshooting process, make sure you’ve tried the basics. Reset the System Management Controller and PRAM or NVRAM. If your MacBook still won’t turn on, it’s time to investigate further.

Faulty Power Source

A faulty power source is a common culprit when it comes to a MacBook that won’t turn on. Try using a different charger or outlet to rule out any issues with your power source.

If you’re using a MacBook Pro, ensure the USB-C port is not damaged. Inspect the port for any signs of wear or corrosion.

Battery Fault

Batteries can fail unexpectedly, causing your MacBook to refuse to turn on. If you suspect a battery fault, try replacing the battery with a quality-tested unit from a reputable supplier.
