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.
And Nada panimayu chta, even if the outlet is "ground" and on the plug PSUs have ground (not all notebook PSU vstrechaetsa), this naznachit chtl earth actually is, it is necessary to check the flap . And Yes, it's not obezatelno solve the problem. Sorry for the uneven handwriting, was written under the impression of opus vehicle. - alycia.Weimann commented on July 9th 19 at 13:36
Yes, in an apartment building this can be a problem. Battery life zemlet - violation of TB. I have the battery grounded (wiring is ancient, and in order to change it - all the walls raskurochit need to do it during the repair), but I'm in a private house and I am sure that she has contact with the ground. But in a high-rise building - plastic pipe can be someone to stand, and the neighbor taking a shower, can not get out of the bathroom, when suddenly on "grounding" the current will go. - Adrienne81 commented on July 9th 19 at 13:39
