Laptop Lenovo g505.
I odes headphone Jack and micro when podkluchenie charging, microphone nachinat to make noise but, when you pull the charging cord from the microphone is working fine. In General any ideas how to fix ?
This is the "norm". Battle of the interference source.
Cure can be replacement for any quality PSU or upgrade to a laptop of a higher class. The laptop is cheap, it will not push high-quality sound card.
As an alternative, buy USB 5.1 audio. The Chinese have is 5-7$. There are still Logitech G430, included is a usb card, I love this, much better built-in

The power supply grounded? There must be at least zero.
And the quality of the PSU depends, it needs to be large enough coil (LC filter), the power supply itself, perhaps better to take the original and more powerful, because if it's for more powerful laptops, so for the more expensive, and that means that he will probably be better.

Wiring ground in the first place if not grounded. At least the outlet to which the computer is connected.
