This may not work for everyone, but here is my experience. The charger does seem to defect while plugged into a wall outlet. The brick itself makes an odd buzzing noise. As others have stated, the laptop won't charge. For me the fix has always to remove the outlet plug from the brick and reconnect. The buzzing goes away and the laptop charges again. I can't speak for everyone, but although annoying, this problem is not a deal breaker. From my conversations with Razer Support, they have said that it has to deal with the static that comes from wall outlets and it is not necessary to RMA. I don't know how true this is, however, I have never had this problem while connecting to a power strip. I've never have had this problem with other chargers, I hope that Razer will address this issue soon.
