Why won't my MacBook turn on?
In order to find a fix for a MacBook that won't turn on, the first thing we need to be very clear about is what is causing this problem. Some of the most common reasons are as follows:
- If we use the MacBook and we have not put the battery to charge, when we need to turn it on it will not.
- The computer is used for too long or suffers some kind of shock. It is very possible that if we use the MacBook for too long it will not turn on. Perhaps the machine was hit by some kind and caused hardware damage.
- The power button does not work.
- Damaged internal hardware. During use, it may have some internal hardware error that prevents the computer from turning on.
- It is also possible that the MacBook has a software conflict and is unable to turn on.
- Power IC. In the event that we check and find that the Mac won't turn on due to the above reasons, it is very possible that the power IC or charging port power board was damaged.
Ways to fix a MacBook that won't turn on
Check battery
It is important to verify that the battery is not depleted or damaged. To check the battery we will have to do the following:
- We are not removing the battery, we simply connect the MacBook to the power source. If it lights up, it means that the battery is exhausted.
- Another option is to remove the battery and connect the computer to the power supply, if it turns on, it means that the battery is damaged. At this point, we are going to have to purchase a new battery.
Broken power button
Obviously, if the power button is broken, we will not be able to turn it on. This button is connected to the keyboard, this means that, if the keyboard is damaged, it will not work either.
In these cases, the only solution we have left is to take the device to a specialist so that they can repair it. We do not recommend disassembling the computer without having the necessary knowledge to carry out the process..
Reset PRAM
One of the most popular ways to fix a MacBook that won't turn on is to just reset the PRAM.
- We remove the battery and connect the charger.
- We wait 30 minutes for the device to stabilize.
- Now, we are going to press the key combination "Command + Option + P + R + Power" for about 5 seconds to be able to reset PRAM, this will restore the default values of the device.
Perform a hardware cleanup
Like all electronic devices, dust is one of the great enemies to which we must pay too much attention. If the device is not cleaned for too long, dust and dirt adhere to the hardware, which will further raise its temperature when we use it; sooner or later it will end up damaging the components. When we take the Mac apart for cleaning, it should be a gentle cleaning. If we are not very sure of what we are doing, the ideal is for a professional to do it..
Restart the operating system by USB
If none of the above solutions work, then it is very possible that the problem is due to a software conflict. In this case, in order to solve it, we will proceed to perform a factory reset.
- The first thing to do is to turn off your MacBook and plug the operating system's built-in USB into the USB-C port.
- After this we are going to press the Options button and turn on the MacBook again.
- We will hold down the Options key until the installation interface appears, now what we will do is choose the USB that the operating system has.
- Next, we will have to choose the language and click on "Disk Utility".
- Here we will proceed to format the partition and then click on the Eraser to be able to install MacOS again.
- When the partition is finished, we proceed to close Disk Utility and reopen the MacOS window, then click install.
- We will perform the installation steps as we normally would.
Once it's done, we'll turn on the Mac to verify that everything is working as it should.
In case none of the above solutions were helpful. The only alternative we have left is to take it to a repair center to be checked by a professional.
