Noisy microphone when charging is connected?

Notebook Lenovo g505.
I have an input for headphones and a micro, when the charging is connected, the microphone starts to make noise, but when I pull out the cord from the charging, the microphone works fine. Any ideas on how to fix this?

This is the "norm". Battle power interference.
You can cure it by replacing it with a suitable high-quality PSU, or by upgrading to a higher-class laptop. The laptop is cheap, they will not shove a high-quality sound card into it.
As an alternative, buy USB audio 5.1. The Chinese have such a cost of $ 5-7. There is also a Logitech G430, there is a usb card in the kit, I use one myself, it is much better than the built-in one

Блок питания заземлен? Необходимо хотя бы зануление.
И от качества блока питания зависит, в нем должны быть достаточно большие катушки (LC-фильтр), сам блок питания, пожалуй, лучше брать оригинальный и помощнее, потому что если он для более мощных ноутбуков, значит для более дорогих, а значит, и сам, вероятно, будет лучше.

Проводку заземлите, в первую очередь, если не заземлена. Хотя-бы розетку, к которой комп подключен.
