When I plug in my Dell Inspiron 15 3567, it's hard to insert the plug. When the cord is plugged into the wall, the light is on, but when it is plugged into the laptop, the light turns off and I hear a spark sound. Took it to my local Micro Center and they said that the power adapter jack was toast and the motherboard might be fried because of it. The thing is, the laptop booted and I could log in after it happened (forgot to tell them that at the store). Could the mobo still be dead if the laptop booted? If not, I could save a lot of money by either replacing the jack myself or taking it to a different repair shop. Thanks in advance.
