Identifying & Disabling piezoelectric component in Liebert GXT3 UPS

Block Image

I bought on eBay an used Liebert GXT3 2000VA UPS for my desktop computer. When power goes off (pretty common where I live) the UPS takes over and its alarm immediately starts beeping, something like once every 3 seconds, what for some people/company may be useful, but it is pretty annoying for me.
I am not electronic savvy but I have discover that the electronic component responsible for the alarm sound is a thing called piezoelectric component. Most of these things are like a small cylinder with a hole in the center, but when opening the UPS I could not locate such a thing.
I have 2 questions:

  1. Could anyone point me exactly where it is located ?
  2. How to properly disable it for good ?

Thanks for any help.

Posting the solution here for future searches.

The piezoelectric buzzer is located on a small board, inside the front panel of the GXT3 2000VA.

I have just added a little of silicon in the hole, let it dry, and now the baby is completely silent.

@tetelestai07 post some pictures of your circuit boards etc. with your question. It is probably easier to help you find it then it is to find a component layout diagram for your UPS. Make sure the pictures are focused and large enough so they can be zoomed into, to identify the components. Adding images to an existing question
