Battery Alert Sound Notification

[bruc33ef]

Somehow I turned on the battery alert sound notification and don't know how to turn it off. Everytime the power cord is slightly jiggled or I slightly change the position of my laptop the sound goes off. How can I get rid of it?
Many thanks!

if you dont have dconf-editor, install it.

using dconf-editor, go to org.mate.power-manager and disable option
