    I just bought a used g72gx-rbbx05. No charge is in the battery so I can't turn it on. When I plug the charger in it instantly has smoke coming from the laptop where the cord plugs. The smoke exits through the speakers. What could the problem be. Windows 7.

    Whatever the problem was, it's probably burned up by now. Capacitor in the power-supply, most likely. >RMA.

    short circuit don't proceed on powering on or charging, would damage the board may be it did. complete disassembly could confirm
    hopefuly a fried power pin circuit if lucky

    Mm. There's an effect circuit and a fuse on the edge of the motherboard, usually.. and that's not actually called the power supply at all :D you're right.

    Could have been just the fuse. How or why I don't know, since you usually have a (now extremely cheap) protection circuit in the charger that will work with anything from 100 to 250v current. ..possible to blow it by using a.. high ampere car battery or something directly on the input, I guess.

    The fuse usually won't start to smoke, though. And it should not be possible to fry anything else on the motherboard without heating up the processor core without cooling (which isn't easy to do anyway now.. might not be possible any more.. takes all the excitement out of the overclock, really..).

    So... probably capacitor in the first circuit on the motherboard. ...Don't really recommend trying to solder in one yourself.

    ...actually.. is it even possible to buy capacitors that can explode now? Thinking about it, I sort of wonder if they aren't even legal..

    Think it could just be a short-circuit in the power-jack..?

    Simply whoever sold it to you needs to buy it back. Whatever it is has, has most likely blown other things on the board as well unless you are really lucky but where ever the smoke is coming out of it is never a good sign.

    The other option is your computer has a bad habit, you could try giving it nicotine gum or patches maybe....

    Seriously -> Refund. Before something catches fire.

    i would have to agree for the most part. return and dont use...probably safe to keep using ut dont take chances. its something from the motherboard. The battery still has a PCM/PCB but that doesn't regulate power to the laptop from AC it only regulates from battery so you do run risk running off the AC cord. I just wouldn't play with fire....literally.
