Re: Squealing /buzzing AC adapter

Hi ,


You would need to get in touch with support as this is not something we can troubleshoot in Community.


I am sure they'll be happy to send you a replacement AC adapter.

Squealing /buzzing AC adapter

2019-01-03, 11:56 AM

Apologies for starting a new thread with the same topic it wasn’t allowing me to add to the existing one.


I too am having this issue with my 10" Smart Display which is on my bedside table. I first thought it was the white noise coming from the bedtime setting then realised it was the power adaptor in the morning.


I returned the unit to my place of purchase and got a replacement which has exactly the same issue the power adaptor makes a whining/buzzing sound this can't be right! Levono must have had a bad production run of the adaptors, besides the issue with the adaptor I love the product. 


Lenovo what are you planning to do to resolve this issue?
