Will charging the MacBook Pro “insert the wrong hole” cause the body to overheat?
Apple MacBook Pro is equipped with multiple Type-C / Thunderbolt 3 ports that users can use to charge laptops. However, it was reported this week that if MacBook Pro users charge via USB-C on the left, it will greatly increase the load on the laptop’s processor, causing the body to overheat and speed up. will decrease accordingly.

In fact, it seems like the slowdown issue due to MBP overheating has been around for a while. In a previous 2017 article on Medium, some netizens pointed out the problem to the “kernal_task” program.
On the other hand, on the Stack Exchange website this month, a netizen responded to the overheating problem caused by charging the left side of the MacBook Pro. He concluded from the background data that the MacBook Pro often has the phenomenon of “kernel_task” Taking too many processor resources can cause the laptop temperature to rise abnormally.
At the same time, the netizen proposed a solution, and everyone can do it: avoid loading from Type-C on the left. In other words, the left port of the MacBook Pro should be used to connect external devices, and the right side is reserved for the charger, so that this problem can be avoided.
What is “kernal_task”? Apple’s support page says this:
One of the functions of the kernel task is to help manage the CPU temperature.
“Activity monitor“It can show that the kernel_task program has a high percentage of CPU usage, and fans may also be working a lot during this period.
One of the functions of the kernel task program is to leave Programs with high CPU usageReduce the use of the CPU to control the temperature of the computer. In other words, even if you don’t feel like your Mac is overheating, kernel_task will still automatically handle the situation that caused the CPU to overheat. It is not itself the cause of these conditions. When the CPU temperature drops, kernel_task will automatically reduce its activity.
It is unclear if Apple is aware of this problem, and perhaps the company will fix it in the future through updates, but as far as we know, the latest version of MacOS has not fixed this problem.
We are not sure if the 2020 version of MBP has similar problems. If you have a 16-inch MBP, you may want to share your testing situation with you in the comments below.
