I had this usp, since 2018 and a few months, back replaced the battery. Now it seem to be emitting like a very low yet audible humming. Like a bug zapper.
It on Ac power and when I got the new battery I charged it 18 hours. It only just now it doing this. I almost inaudible but won't to know of this is normal?
