Hello

 

 i bought my V5-591g in september and since day one i have this problem.

if laptop is not connected with power plug It make this  Whining high pitched noise.

i also notice that touchpad  is not responding well.  i download drivers for touchapd two of them but non of them works correctly.

 

i send it to service, they replace LCD and say to me that they dont hear nothing and laptop is normal. one even said that this could be normal

It may need to be checked again by the Acer service center. I suggest you contact them again to request repair. You might provide them details on how to duplicate the problem, like when does it occur, where on the laptop is it the loudest. It may be within normal range for noise but it is very noticeable the repair tech should be able to hear it and address the problem.
