    Dell XPS 17 L702X power issue

    Hello!

    Here I have a Dell XPS 17 L702X I purchased in November of 2011.
    I have replaced several components over the years (both hard drives, keyboard, fan, touchpad/panel, battery, AC Adapter, and some ram [in order]) and all in all the system typically runs rather well, aside from the occasional overheat. Anything that goes terminally wrong with a component is usually quickly fixable... until recently.

    I was watching last week's episode of Game of Thrones when I noticed the machine was running on battery. I unplugged and replugged the system, the pilot light for the AC Adapter came on for a little bit, but then stopped coming on entirely.

    I ordered a DC Jack replacement online (the part that the screw goes through on the original was broken... in the new piece the part was two hairs too low and wouldn't fit in my machine until I knifed it off, not sure how much that matters, it's made of plastic. Though it should probably be screwed down regardless, but how could I?)

    After waiting a week for this new part to get here, I installed the new DC jack and the system would still not recognize the presence of external power. It still works on battery, however.

    So, not sure if this is exactly the right place for this issue or not, though I was referred here by the IRC channel for the /r/techsupport subreddit.

    Any and all help or advice would be appreciated, and I'll try to provide more information as needed.

    Thank you so much,
    Byronius

    I think you should try to get the schematic, that is the only way you can follow the DC pad.
