    Purchased a universal AC adapter for notebooks from Radio Shack and having a problem that hopefully one of you might solve
    It runs fine for roughly 5 - 10 min and then the light goes off and it basically stops powering up my notebook. I have to unplug it from the wall outlet and plug it back in. I have to repeat this procedure every several minutes. I have set it at 19v, as per compaq's specs. I'm not sure if the AC is over heating and it automatically shuts off, but it's not running hot.

    It may have the voltage required, but it may not have enough amps, and that can cause problems. Check your laptop manafacturer sticker where it indicates that it uses 19 v and see what amperage is required, then check your universal power adapter and see what amperage it puts out. Also another note is that sometimes those universal power adapters have a polarity switch and you need to make sure you have the polarity right. Is your system using alternating current or direct current?
