    That's correct--I haven't even started disassembling yet. Just making sure everything is working now. Ok, I'll try that. Dumb question though... Where exactly should I put the leads?
    New AC DC Jack Power Port Motherboard Connector Socket for Asus G53J G53SW G53SX | eBay
    That is the part I bought. Should the red lead go to the pin where the AC part goes? And the black to the copper on the other side?

    Yeah, I picked up the 90 degree connector piece and it actually fits my 150EM and powers it (they actually perfectly match), so I'm pretty positive the AC adapter still works.

    Would desoldering wick work to remove the old jack as well?

    To measure resistance the polarity of the leads doesn't matter, one lead goes on the center pin (or whatever soldering point the center pin connects to) and the other to the soldering point for the ground contact. Sorry I can't be more specific, I've never done this repair and don't have a jack to refer to.

    Well it depends on how good your multi meter is, it should not matter but on some cheaper ones it can make a difference.

    Hey C4RN I have an Asus G53S and I'm really worried about it and couldn't figured out how to pm you or your email. I think the DC jack may be the problem but I turned it on this morning and it started smoking and smelled like burnt plastic. What do I do?!? Sorry if this is the wrong place to post but I'm new and freaking out haha thanks a bunch >.<

    You can't PM until you have 5 posts. You would take it to be investigated by someone who knew what they are doing but it may be dead.

    This way will work as i'm still subscribed to my own threads.

    What's the history of the laptop? Did you buy it new or second hand? How long have you had it?

    Does it still work on battery? Does it only spark when you plug in the power adapter?

    If you feel comfortable taking it apart check the continuity between the ground and the power pin, you shouldn't get a result. If it turns out the ground and the power pin are causing a direct short then it's better off replacing the motherboard.

    I bought it used for $600 and it's worked fine for a few moths. Lately it has had trouble charging as it does only smoke/spark when plugged in. It charges fine when the computer is turned all the way off. I'm not comfortable taking it apart but I used a multimeter on my charger and it's output was 16.5 and should be 19.5 if that matters. Thanks a ton man

    If it was me I would just replace the psu and see what happens. Since we already know it's not with in specs that would be my first step.

    I talked to an IT and he said he could replace the charger jack or the motherboard but the charger jack saudering wouldn't be strong enough so e couldn't place a warranty. And that it'd only work if I was gentle. The motherboard is more expensive but he could warranty it. He also has an asus identical to mine. So should I bring up CPU?

    He would have to take out the motherboard and probe it to see if your dc jack was the issue. Sometimes you will get boards that look fine or boards that somehow burn a hole straight through the motherboard (the asus g71 series is infected with this problem). Sometimes replacing the dc jack doesn't fix the direct short that causes the issue. Though since you said it was sparking you should have him take it down to the board and see what's going on. Sometimes the solder breaks loose from the pad and the pin that has 19+v intermittently makes contact with the pad and causes the sparking.

    I would think in this case it's best to replace the dc jack and reinforce it with a little bit of plastic epoxy.

    Also you can get the right angle adapter that i recommend from this tutorial.

    Here's a link to it.

    Right Angle 90 Degree Converter for 5 5 x 2 5mm Power Connector Bixpower LC53 | eBay

    I had my g53sx for a couple years and never had any issues with the dc jack because I bought the right angle adapter. Every newer ROG laptop I have bought and sold has been sold with this right angle adapter.

    Just make sure he uses a new dc jack.
