LENOVO 330S Sound Port problem on shtudown


I plugged loud speakers system on the jack 3.5 port of my Lenovo 330S 14IKB : it works fine.

But... When i shutdown the laptop, the speakers continuously emit a humming noise.

I have to disconnect loud speakers from the port jack 3.5 for this sound to disappear.

I updated drivers, bios and tested with 3 brands of different cable speakers. I even tested with a bluetooth receiver on the speakers to replace the cable jack 3.5. The problem is always the same.

Has anyone met this concern? How can we solve it?
thanks in advance
