So, What Could Be the Reason Behind the Issue?

Well, if your MacBook Pro would not turn on, then it could be due to more than one reason. For instance, it could be due to a faulty charging cable, a damaged power adapter or a software or hardware problem with the device. Some reasons might be very similar to what might be the case for a MacBook Air not starting but a few may be specific to the MacBook Pro not powering on.

Check the Power Supply

First thing first, check your MacBook Pro’s charging cable and adapter. Make sure that the Magsafe charger is fitting properly in the jack and is not loose. Also, ensure that the cable is not damaged. A faulty cable can not only cause issues with charging but can also damage the charging port, and even the battery in some cases.

Apart from the charging cable, double-check the adapter and make sure it is not getting too hot while charging. If possible, try to use a different power adapter and cable to charge your dead MacBook Pro and see if it is taking charge and if it boots up.

If using a new or a different power adapter does not help then there is a strong chance of the problem being at the other end of the connection and not with the cable. A faulty DC/Charging Jack or a service battery might be preventing your device from starting up. In this case, it is best to contact a reliable MacBook repair service centre to help you with diagnosing and fixing the issue accurately.

Reset the SMC

Resetting the SMC (System Management Controller) can often fix certain issues related to battery, power, fan and some other features too. So, if you are still unable to turn on your MacBook Pro or your Apple notebook appears to have gotten frozen at the Apple logo, it would be apt to give this solution a try.

To get going, plug in the power cable and then press the Shift + Ctrl + Option/Alt keys and the power button simultaneously and hold them for at least 10-12 seconds. Next, release all the keys and then press the power button to try and restart your MacBook. If there was a minor issue with power or battery which was preventing your device from booting up, that should get resolved and the MacBook should start up successfully.

Important:

• Please note, M1-powered MacBooks do not come with SMC. It means you do not need to bother about resetting SMC on your M1MacBook Pro.

Reset the PRAM / NVRAM

Another reliable solution for fixing a dead MacBook Pro or solving the ‘MacBook Pro Won’t Turn On’  issue is resetting the PRAM/NVRAM. For those unfamiliar with the terms, NVRAM (Non-volatile Random-Access Memory) and PRAM (Parameter RAM) are the areas in the memory of the device that store data such as volume settings, startup disk selection, screen resolution and even kernel panic information. Resetting them often fixes several minor issues which may be preventing your device from starting up.

To get going, hold down Command, Option (Alt), P, and R, keys at once and turn on the device. Make sure to hold down the keys until the MacBook restarts again. Better still, let it restart twice. Then, release the keys at once. Now, your MacBook should restart normally if the issue was with the NVRAM/PRAM.

Important:

• Though the M1-powered MacBook Pro does come with NVRAM, it works a bit differently on the device. Notably, Apple’s M1-equipped MacBooks feature parameter memory where you can view and customise settings with the terminal command NVRAM. However, they don’t allow resetting NVRAM.
