avoid explosions while testing laptop power cables

[who?]

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.

Are you sure you should avoid electrocution? You can't defy natural
selection forever, you know...

Defiance is the order of the day with the most recent four generations
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.
