Having your MacBook Pro turn off when you’re in the middle of important work can be frustrating. When your MacBook Pro turns off when you unplug it, this hints at a problem with the battery or the system.
When the device turns off spontaneously immediately after you’ve unplugged the charger, it might be because of a high cycle count. It could also be because it’s time to reset the SMC or NVRAM or PRAM.
We discuss what exactly to do when your MacBook Pro turns off when it is unplugged, in this article. Let’s take a look at all the solutions for both Intel and Silicon MacBooks.
Let’s get to it!
What to Do When MacBook Pro Turns off When Unplugged
The issue could most probably be related to your battery. So, the first step is to check your battery health and the cycle count on your system. For this, go to the Apple icon on the top and open System Settings. Then, click on General and go to the About section. Scroll down, and choose System Report. Here, choose Power from the left menu option. You can see the battery’s health and cycle count.
If your battery health is not good, this could be an indication that you need to replace the battery or magsafe power adapter. However, if everything looks good here, there are a few other methods or options you can try, such as SMC or NVRAM reset, software update, etc.
What To Do When MacBook Pro Turns Off When It Is Unplugged (Fixes)
I have gathered all the methods and fixes below in detail so that you can try to fix the error on your MacBook Pro. Try all the methods before contacting Apple support.
1. Check Battery Health And Cycle Count
Since your MacBook shuts down as soon as you unplug the charger, it could be because your battery health is left unattended. Here is how you can check this.

Step 6: Under the Health Information section, you can check the Cycle Count, Condition, and Capacity.
If your cycle count is near 1000 or anything on a much higher level, then your battery is deteriorating, and it might be time to replace it for your system to be running smoothly again. Once you determine this, you can fix the issue above.
2. Reset SMC
If your battery health and cycle count seem good, you can try resetting the SMC, which might fix the issue. Below are the steps you can follow:

Once you are done with resetting the NVRAM, wait for the system to start, and you can make proper settings for the same.
