|When I plug in the power cord to my Dell 1558 i7, the sound is first distorted (it sounds like space ships are flying in my living room) and then the sound is basically gone and I cannot hear movies, music, etc. It's as if I have turned the sounds way down. It's VERY muted. |
When I unplug the power, the sound is fine.
I exchanged batteries, and had the same result.
Is it a problem with the sound card, the power adaptor, or something else?
Thanks for your ideas!
