The adapter makes buzzing sound.

[Somsinghal]

The adapter of my laptop makes buzzing sound when the electricity is gone and I charge it on inverter power.

It only makes sound when I plugged it in inverter power. And the buzzing sound comes from the earphones too when plugged in laptop. The adapter and the earphone make the buzzing sound simultaneously when the charger is plugged in the inverter power. It only happens when it is plugged in inverter power. And on normal household electricity, everything seems fine; no buzzing sound. Is it normal or should I contact HP.

I reviewed your post and I understand that the adapter makes a buzzing noise when you use the inverter power.

Don’t worry, I assure you I will try my best to get this sorted.

It looks like an issue with the inverter you are using. Using you hear this buzzing when you use a square wave inverter. If you use a Sine wave inverter usually you will not hear the buzzing noise.

I hope that answers your question and you have a great day!
