    Recenly I've replaced the dc jack and burned traces off my laptop by following the advice I've been given. The link to the thread i made on how to replace the jack is below. I tried to power on the laptop after but nothing happened. Could my motherboard be fried now from the burned traces making a short or a dead battery? I've got a multimeter to help diagnose the problem.

    Most likely a multi-layer board, the thru plating is gone. So the inner layers of the PCB are open. Get another mother board.

    I only bridged the pins of the dc powerjack to where I sanded on the top layer of the motherboard and not the bottom if it's a multilayer board.

    For laptops the motherboard is pretty much the machine and is proprietary

    I wouldn't change it unless the machine is fairly new or very high end.

    It wasn't water damage? I see white stuff not only where you sanded, if the laptop is an old one you could buy the MB on eBay cheap.
