Hello everyone, hope some1 will be able to solve my problem. I bought a yoga 710 in praha but i live in italy. When the notebook is charging there is a buzzing noise coming from the bottom right part of it and im afraid either the charger or the notebook itself is defective. The product is obviously still in warranty, what shall i do at this point?

Hi there, Lenocre -
Thank you for writing in to the Lenovo Forum - happy to have you here today.
Interesting that it occurs with both batteries and both AC adapters. To be clear, the sound occurs only when the battery has less than 95% and is charging? (We reduce the charge rate at around 95-96% to "slow down" the charging and take it easy on the battery).
Does it matter whether the computer is on or not while charging? Does it make the sound only when on, only when off, or in either case?
If you stretch out the cords so as to move the AC adapter "brick" away from the system, can you tell if the sound is coming from the PC or the adapter brick? If from the PC, generally where on the PC? Does your configuration have the CCFL or LED?
Update us how it goes.

hello thx for the time u dedicating to me.
the problem is definitly not the ac adapter since i notice that the buzzing noise is present even when unplugged, although it is very very quiet. When the laptop is charging instead the noise is very loud (at least for me, since i find it very annoying when im studying). The spot the sound comes from is around the right side of the keyboard (maybe from the CPU?). I made some benchmark tests and performaces seem to be stable and at the same level of the yoga 710 tested on the web.
i sincerely hope some1 or something can help me get rid of this electrical buzzing noise and that this problem wont actually affect the health of my laptop, spent a lot of money on it
