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. Adicionar imagens a uma pergunta já existente
