Squealing AC adapter

2019-12-18, 1:06 AM

The hub's plug is producing a squealing sound. 

 

Lenovo sent replacement plugs to no difference and their tech support guy apparently found no fault.

Hi ,

 

This might be a grounding issue, have you tried plugging into a different plug? perhaps directly to wall outlet?
