Weird noise coming from the left of the touchpad

cpcn16

I just bought an acer aspire 5 a515-57-753j,and there is a weird noise coming from the bottom left of the laptop,like a buzzing,it's pretty quiet,but pretty anoying in a quiet room.I still have 14 days to return the laptop.Is this a common issue and should i be worried about it?I found a few more posts about it from the past,but didnt find a solution to fix.It makes the noise more when in maximum performance mode.Rarely it is made without input from me but it happens every time i use the touchpad,especially when i scroll with both fingers.

Do you apply pressure on touchpad when this happens? Or just use it for touches and not presses?
