  1. Hi!
    No! You were *definitely* correct. I'm here to say that substituting laptop
    power supplies between different models and makers (as long as the
    connectors are completely compatible!) is generally OK as long as you have
    checked the voltage (both listed and what is actually being put out when
    unloaded), current rating and polarity *first*. The voltage should be exact
    and the polarity had better match as well. Current supply can be higher or
    equal to what the computer expects.

    There is some leeway in most designs for current draw and possibly voltage,
    but you can't always count on this and won't find it documented anywhere
    short of personal experience.

    If you don't check these factors before plugging things in, you're looking
    at the possibility of causing anything from instant destruction on up to
    slow cumulative damage to the computer.

  2. Hi!
    Hmm...impressive bang? Lots of smoke? Sudden bright light from within? Sound
    output equivalent to a 1,000 watt home theater system but only for a second?

    I think I saw geesus, but IIRC the smoke got out. I was probably after
    the 1000 watt stereo effect, hell I was only a 9yo kid sniffing glue. [*]
    And back then, we thought Mad magazine was an anarchist publication. ;)
