buzzing sound when charging

HP Recommended
HP Pavilion 15-cs
Microsoft Windows 10 (64-bit)

I can here buzzing sound near the position of letter A on the keyboard when I put on my adapter. That sound is smaller when the laptop is not charging.

It's not affect much on my experience however I feel really annoying to here that sound when I work in quite place.

I have used my laptop for about 1 year and a half. 

Can anyone help me ? 

Thanks

Notebook should not "buzz", of course.

 

Check whether the AC adapter might be the culprit.

I realize the AC adapter is outside the computer - if it is near the computer, it is worth a quick check.

Make sure the cord is not wrapped tightly around the adapter.

 

Open the case and look.

See if you can find what is causing the "buzzing".

The battery might be in the first stages of "inflating".

What?

All batteries die, some do so quietly and some first inflate and then fail.

 

If the battery is indeed "inflating" a bit, the "buzzing" might be due to one component touching or moving against another.

 

If it is not the battery,

If the computer contains an internal fan, 

The fan might be buzzing due to dirt / dust / wear-and-tear
