Hi Chuwi,
I just bought a Minibook X N100, when the battery is charged 100% and the charger is connected there comes sounds from the charging port, like electricity sounds. Is this a problem or is it not dangerous ?
Because I like the laptop so if it’s no problem I will keep it then.
Best regards

It’s “normal”.
The electric whine (coil whine) comes from the coils in the power delivery circuit and while it is annoying it won’t damage anything (or at least it shouldn’t). My Lenovo Ideapad Gaming 3i is 5x more expensive laptop and there is still coil whine and I had it for 2 years now.
Some laptops have more of it, while others none at all. Even PCs can have coil whine.
Oke, thanks for the info, I don’t really notice it and it’s a laptop for on the road, so I will keep ik then if it’s not a problem.
