My laptop power supply kicked the bucket, it just randomly stopped charging. I went to Amazon and bought a new cord for my Dell Inspiron 15-3531 from AC Doctor INC. The cord supposedly was for my laptop. When the cord arrived i plugged it in and heard several loud beeps from my laptop then the screen went completely blank and never turned back on. The mother board has some scorch marks where the power supply connects to it. Does anyone have any idea what I could do to fix this problem? if possible without buying a new motherboard/laptop.
