    My 4 year old Gateway laptop battery has finally died (I used to be able to charge it, but it wouldn't hold the charge, and would die before it even got past bootup). Now, I can't get the AC cable to charge the computer at all.

    Is there a simple fix here (a new AC cable?), or is it probably something bigger?

    I'm not using the computer; in fact, I sold it last night, but was told that it won't charge at all now.:o

    I would try a voltmeter on the ac adapter and see if any power is going through it. If not, then replace the adapter. If power is going through it, then you are pretty well stuck... it's may not be worth fixing. It could be that the plug on the laptop has detached from the circuit board it's attached to, which would mean taking the laptop apart and re-attaching it.

    Actually, I just remembered: I tried my brother's AC cable from his Gateway laptop and it didn't power it at all.

    then it probably isn't the AC at all. the battery is probably shot.

    wouldn't the AC cable power the computer even if the battery was dead?

    I tried it both with the battery in the computer, and with the battery out, and neither worked to turn the computer on.

    Im guessing the soldering on the AC jack connecting to the motherboard is broken.. if you are good with a soldering iron, take it apart and put some back on to see if it likes that.

    this is what happened to my gateway.

    i had to push the plug in reaaall hard for it to charge.. and finally it eventually gave out.

    i took it apart and resoldered it. works like a champ

    that sounds a lot like what I had to do... I've got an old soldering kit laying around; looks like its time to get that bitch out.

    PS. I'll post pics when I get it open, just so I can maybe get some confirmation on the defect.

    thanks guys

    If he took it to a computer place that fixes these things, shouldn't they know what's wrong with it? If it's getting to the motherboard, but no further, probably a bad motherboard.

    Sounds like the internal power supply is shot.

    The brick downconverts from 120VAC to 12VDC, but there's still some power conditioning equipment inside the laptop to convert 12V to 5V/3V and whatever else the motherboard needs.

    Yes, but the motherboard is after that point... if the motherboard is getting power, that part is probably fine

    I'm pretty sure the internal power supply is on the motherboard...but either way, it depends on where they stuck their voltmeter.

    I would not be at all surprised if the internal power supply burnt out from constantly working at maximum load, running the laptop and trying to charge the dead battery at the same time.

    You're screwed... not likely going to be worth fixing unfortunately.

    You could probably get a used identical machine on eBay, then plug your RAM and hard drive into it, and carry on like nothing ever happened. Should be about as expensive as fixing the laptop you have.

    Laptops aren't like desktops; once they break, if you don't have a warranty, they're pretty much totaled.

    What's the model number of the machine? Search on Ebay for a motherboard. Since it's a couple years old, it should be too much.

    I had a Dell at work that died. I got a replacement motherboard w/ CPU on Ebay for about $40. Had the machine running like new a half hour later.
