After a week of a variety of tests found an interim solution. This happens when turbo mode is activated on the processor. It occurs when the laptop is hot, or only turn on. The processor has been tested Intel® Processor Diagnostic Tool. No abnormalities were found. I disabled the turbo mode on the CPU power management, putting in 99%. Here
description with pictures how to change the percentage.

Now you do not receive a message replacing the adapter. Probably there are problems in the drivers chipset and the power supply when you turn on the turbo mode which lead to such consequences.

Hi friends Just do this simple step to fix this issue
This happens only due to Windows update which updates ur bios. Frimware
All u have to do is go to bios by pressing FN key and. F1 or F2 simoutensly .if u have doubt u can press both F1 and F2 both but u have to keep pressing FN key.
It will take u to bios
After going into bios just plugg in ur adapter and wait . See if still u face the same issue .even in bios . If u Don't find ur pc getting shutdown
Then this is not a motherboard issue it is a bios update issue because if motherboard issue is there it should happen even when ur system is in bios
Now for simple solution exit ur bios login to ur laptop go to device manager. Click on batteries then uninstall the drivers which is under the batteries . It will fix
