How to fix a MacBook that won't turn on

  Suddenly we found our MacBook not working.  How can we fix it?  We will see a guide with many simple solutions that any type of user can implement, regardless of their technical knowledge.

  Why is my MacBook not working?

  In order to find a fix for a MacBook that won't turn on, the first thing we need to be clear about is the cause of this problem.  Here are some of the more common reasons:

      If we use a MacBook and don't charge the battery, then when we need to turn it on it won't.

      The computer is being used for too long or is experiencing some kind of shock.  It is very likely that if we use our MacBook for too long, it will not turn on.  The device might have been infected with some kind and caused hardware damage.

      Power button not working

      Damaged internal organs.  During use, there may be an internal hardware error that prevents the computer from turning on.

      It is also possible that your MacBook has a software conflict and cannot turn on.

      IC power.  In case we checked and found that your Mac won’t turn on for the above reasons, it’s very likely that the power supply IC or the charging port power board is damaged.

  How to fix a MacBook that won't turn on

  Check the battery

  It is important to check that the battery is not exhausted or damaged.  To check the battery, we will have to do the following:

      We do not remove the battery, we simply connect the MacBook to the power source.  If it lights up, then the battery is exhausted.

      Another option is to remove the battery and connect the computer to the power source, if it turns on, then the battery is damaged.  At this point, we will have to buy 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 attached 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 professional so it can be repaired.  We do not recommend disassembling the computer without having the necessary knowledge to perform the process.

  PRAM Reset

  One of the most popular ways to fix a MacBook that won't turn on is to reset the PRAM only.

      We remove the battery and connect the charger.

      We wait 30 minutes for the device to stabilize.

      Now, we will press the key combination “Command + Option + P + R + Power” for about 5 seconds until we can reset the PRAM, this will restore the default values ​​of the device.

  Clean the devices

  Like all electronic devices, dust is one of the biggest enemies that we have to pay close attention to.  If the device is not cleaned for a long time, dust and dirt stick to the device, which causes its temperature to increase when used;  Sooner or later it will end up ruining the components.  When we disassemble our Mac for cleaning, it should be a gentle cleaning.  If we are not quite sure what we are doing, it is best to have a professional do it.

  Reboot the OS via USB

  If none of the above solutions worked, then it's very likely that the problem is caused by a software conflict.  In this case, in order to resolve it we will proceed with doing a factory reset.

      The first thing you need to do is turn off your MacBook and plug the USB built into the operating system into the USB-C port.

      After that we will press the Options button and turn on the MacBook again.

      We will hold down the Option key until the installation interface appears, and what we will do now is choose which USB the operating system has.

      Next, we will have to choose the language and click on "Disk Utility".

      Here we'll go to Format the partition and then click on 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 carry out the installation steps as we usually do.

  Once that's done, we'll boot up your Mac to verify that everything is working as it should.

  In case none of the above solutions helped.  The only alternative we have left is to take it to a repair center to have it checked by a professional.
