    Hi all,
    what is the best way to test a laptop's power cable?
    I recently used a multimeter to test the output from the adapter, there was
    no power. I then tested the output from the mains (the cable that goes from
    the wall to the adapter. Needless to say, there was a minor explosion as the
    power arced to the multimeter pointer. That cable was evidently good! ...
    but how do I avoid explosions and possible electrocution next time?

    Set the multimeter correctly. Sounds like maybe you tried to use the
    Amps range to test across a power source? You should gain a basic
    understanding of electricity before you go poking around in these
    things. Switchmode power supplies (which is what these laptop bricks
    are) are no place for beginners.

    of man on this planet. The number that actually knows what is going on
    is far lower than in decades past.

    They are stupid enough to actually think that anarchy would work...
    while they play with their sophisticated gadgetry and talk on their Dick
    Tracy personal radio phones while driving their high efficiency
    automobiles.

    A society in anarchy would be too stupid to come up with the gadgetry,
    much less any of the rest of it, so how do they think they would survive
    if all was anarchy?

    Goddamned Ted Kaczynski mindset idiots is what they are.
