MacBook Pro make charging sound
hello.
i have just bought a MacBook Pro. and it ia always plugged to charge.
but it still makes charging sound. it happens 2 or 3 times when I use it, and use it like for 3-4 hours.
why does it do that, is the charging cable I have bad? or is it the port it is wrong whit? should I contact Apple support?
MacBook Pro 13″, macOS 11.4
