There is this buzzer in this UPS (uninterruptible power source) circuit. I want to remove it from this circuit because it make a lot of unnecessary noisy. Black-outs happen too much in my area. Sometimes they happen in the deep night, when I am sleeping, and this little buzzer wakes me up by freaking me up. I always immediately realize it when there is a black-out, so this buzzer is really not needed.
I am not able to de-solder it. Because the PCB is strongly embedded into the case by some very hard clippers. It just won't move.
How do I remove this buzzer from the circuit, or shut it up without removing? I don't plan to re-use it, so it is OK if it is destroyed in the process. I just don't want to get into risk of damaging any other part of the PCB.
