When i disconnect the powerconnector from my MacBook Pro (15-inch, Mid 2012) an annoying sound starts.
Short movie to show what happens
Anyone any idea how to stop this?

Hello and welcome.
Hmmm...that is curious. Not sure I have seen that issue previously.
-Do you have any external devices connected - like a hard drive?
First suggestions would be to try the following resets:
-How to reset the SMC of your Mac
-Reset NVRAM or PRAM on your Mac
