Xiaomi Mi Air 12.5 m3 7Y30 Electrical buzzing noise
Hi, I'm sorry I have to write this post in English but I don't know I single word of Chinese and I need help.
There is a problem with Xiaomi Mi Air 12.5 with Intel M3 7Y30. It makes a very annoying electrical buzzing noise coming from the USB C port and USB 2.0. It is very high pitched. It only appears when battery is lower than 45% and when you turn on the keyboard backlights it stops. However, the sound appears again inmediately after the keyboard backlights turn off. This problem seems to be with all laptops, not only mine. We didn't find a solution yet. Some say it can be solved with a BIOS update. Can someone please help me?

嗨，對不起，我必須用英文寫這篇文章，但我不知道我單身漢語，我需要幫助。
使用英特爾M3 7Y30的小米米Air 12.5有問題。 它使USB C端口和USB 2.0產生了非常煩人的噪音。 這是非常高的。 隻有當電池電量低於45％時才會出現，並且當您打開鍵盤背光燈時，它將停止。 但是，鍵盤背光燈關閉後，聲音立即再次出現。 這個問題似乎是所有的筆記本電腦，不僅是我的。 我們還沒有找到解決方案。 有人說可以用BIOS更新來解決。 有人可以幫幫我嗎？
