Various potential causes can lead to this issue, including problems with the power connection, software, and even the macOS. This post will analyze those causes and help you figure out the issue you are facing. So that it could become straightforward to fix the error.
Main Causes of Mac Not Turning On
As mentioned above, there are many causes of MacBook not turning on. In this part, you will get more information about them and you can compare them to your practical situations.
1️⃣ Faulty Battery and Power Connection
If you can’t open your Macbook, the first thing you need to check is the battery. Sometimes, you may find that your MacBook battery is dead. Then, try to open the MacBook after charging it for a while. However, your Mac may still turn on. In this situation, it’s advisable to try another charging cable.
2️⃣ Display Issues
This problem is very easy to recognize. If you can hear the noise when you start this device, but nothing shows on the screen, it will be almost certain that there is a display issue on your Mac screen.
3️⃣ Hardware Failures
Some important components of the Mac, such as SMC and RAM, may also be damaged and lead to the issue of the Mac not turning on. In some cases, the RAM can get damaged by water. That is why you should check for the signs of liquid damage.
4️⃣ Problems with macOS
If there is an interruption during updating the macOS, such as a sudden power loss, it will lead to a corrupted macOS installation. As the corruption will cause startup issues, it’s likely your Mac won’t turn on.

For different models of MacBook, there may be some differences in the specific operations of resetting the SMC. You can choose a suitable tutorial based on the MacBook you are using.
