Why does Wi-Fi completely disappear on a laptop when I connect the charger?

Question

WiFi

Hello. I have the following situation.
I use wifi on an acer laptop with windows 10 operating system.
The hotspot has a weak signal, but at my desktop it catches, but only if the laptop is disconnected from charging!
Those. I'm sitting at the table. If I plug it into a socket, then the wifi network disappears altogether. But if you turn off the network and the laptop starts running on battery power, then the wifi network appears and the Internet works.
Of course, it is unlikely, but does anyone have any thoughts))?

Answer 1

see what happens to the adapter at this time.

Answer 2

It looks like a problem with the power circuits, and specifically, the adapter "noises" a lot, unfortunately this can only be found out by replacing or even better with an oscilloscope.
Vryatli is a software bug.
