Does MacBook make noise charging?

What does it mean when your MacBook Pro starts beeping?
When you start your Mac, it will automatically run system diagnostics. If you hear this pattern of beeping, it means that the Mac could not find any RAM installed. Either your computer’s memory was removed or something is interfering with the system checkup.
What kind of charging sound does a MacBook Pro use?
With the introduction of the 2015 MacBook, Apple decided to ditch MagSafe, and the charging LED, in favour of USB-C. As a result, Apple brought the charging sound present in iOS over to the new MacBook, and subsequently to the MacBook Pro with the 2016 refresh.
Why is my MacBook Pro not charging after I plug it in?

What kind of cable do I need to charge my MacBook Air?

What to do if your MacBook Pro power adapter is not working?
If your USB-C power adapter isn’t charging your MacBook, MacBook Air, or MacBook Pro, first try unplugging the power adapter from the power outlet, waiting a few seconds, and plugging it back in. If that doesn’t help, check these things.
